[00:00:00] Beth Vukmanic: We. Often talk about sustainability in the vineyard, but that doesn't account for the whole picture. An important theme of sustainable wine production is the ability. To elevate the practices as a whole, from block to bottle.
[00:00:12] Welcome to marketing tip Monday with sip certified. We know. That customers are looking for wines labeled as sustainable. While our longer. , form episodes help you learn about the latest science and research for the wine industry. These twice monthly micro podcasts. We'll help you share your dedication. to sustainable wine growing.
[00:00:30] After months of careful cultivation in the vineyard. The grapes still have a lengthy journey ahead. It's no secret that the. The journey takes place in the winery, but what exactly does it take for
[00:00:40] in this week's marketing tip. She shares four ways. Ways. That you. Can approve the sustainability at your winery.
[00:00:47] Number one is to sanitize smarter. Safe cleaning and sanitation practices are essential in wine-making, . But the financial. And environmental impact of sanitation products can add up and lead. A sustainably minded business to look for better solutions.
[00:01:03] Cambria periodically runs trials and explores. Floors alternative products to see if they can sanitize in a more eco. Eco-friendly way.
[00:01:10] When testing paracidic. , acid. Abbreviated PAA an organic. Peroxide based sanitation, liquid, commonly used in food and beverage industries and health care facilities. Cambria's, his team had two questions. One, could they lower their solutions, concentration and maintain effectiveness. And two could they reuse a batch of the PAA solution more than once.
[00:01:34] To answer the first question, they mixed up a range. Of PAA concentrations and got to sanitizing. When. They used ATP swabs to test the bacteria and yeast on. They're sanitized areas. They found that they could use less of the product. Product to get the same results.
[00:01:50] The answer to their second question was also a yes, they found. And that they could use. Certain PAA concentrations up to three. Times with a hundred percent effectiveness. Samantha says. Says, researching and trying different products can lead to a cost. Cost benefit and possible switch to a more effective, less impactful. Product.
[00:02:10] G Help them reduce. Both product and water while still maintaining a safe sanitation. Practice.
[00:02:17] Tip number two is to recycle your lab. Plus. Plastics plastic is one of the hardest materials to dispose of. In an environmentally responsible way. Wineries know this well, because. Because commonly used lab plastics, can't be recycled in the normal stream.
[00:02:32] Cambria works with Polycarbin, a platform. For recycling and . remanufacturing lab plastics Polycarbin takes used. Scientific plastics and re manufacturers them into more tubes. Pipette boxes and pipette tips. Their system creates. A closed loop, supply chain. That ensures that Cambria's has plastics don't end up in the landfill.
[00:02:56] To make the deal even sweeter, Polycarbin tracking software. sends Cambria, a monthly report on the impact of the recycling practices.
[00:03:05] In March of 2024. They recycled 24 kilograms of plastic reduced 144 kilograms of CO2 emissions and preserved 220 cubic meters of water. And that's only for one month.
[00:03:18] But Cambria doesn't stop at recycling. Their lab supplies. They also work with TerraCycle, a recycling company that collects. And recycles materials that are not generally accepted in the traditional recycle. Recycling system.
[00:03:32] For example. Example TerraCycle sends Cambria boxes for disposable coveralls. safety glasses and ear protection so that they can be sorted. Cleaned and sent it to third party partners to be produced into. Into usable forms.
[00:03:46] Tip. Number three conduct, yearly audits.
[00:03:50] While, responsible waste management is the goal. For any sustainably minded business, Samantha notes, you don't know how to improve if you don't know where you're starting from. Annual waste. Audits help. Cambria . Analyze their waste. And how it's being disposed. Samantha tells us they collect. They're trash and recycling separated out and see if things are being disposed. Of correctly and assess if staff training is needed. Keeping stock. Of the type and quantity of waste and where it's going is key to. Making decisions that have less impact on the environment. In fact. This is exactly how they transitioned to recycling their lab plastics.
[00:04:27] Samantha tells us . While they're lightweight. There's a lot of it. We looked into how we could improve this and ended up finding. The plastics, recycling options.
[00:04:37] And tip number four is to get involved. Jackson family wines. Cambria's has parent company take sustainability. To the next level with their program rooted for good a roadmap. Map to 2030. It's a 10-year sustainability and climate. Action plan that outlines the goals and initiatives designed to. Lead climate solutions. Create a positive social impact. And support the Jackson family's long-term vision for a sustainable. , future.
[00:05:03] Part of. Their plan centers around social responsibility and their employees. Play a significant role through volunteerism. Every employee gets. To paid. Facility. Volunteer days per year. To head out and do good as a group. Plus one to two paid personal. , volunteer days to find other opportunities that align with their values.
[00:05:24] They help their communities by volunteering for local events. Cleaning up trash at beaches and historical sites and much more.
[00:05:31] Their staff have volunteered over 6,000. hours. That's the equivalent of one person working nearly three. Years of 40 hour work weeks.
[00:05:40] With the business behind the team and supporting their. Community. It's no surprise that everyone really enjoys. . Community service days.
[00:05:46] Let us know how you have made your winery more sustainable.
[00:05:50] Listen up sip certified members offer your club members. . The chance to experience yours and other SIP certified brands in February. 2025.

[00:02:27] Craig Macmillan: Welcome to Sustainable Wine Growing with Vineyard Team. Our guest today is Alyssa Whitcraft. She is Executive Director of NASA Acres, and we're going to talk about all kinds of exciting stuff that she's involved with, and I'll let her explain those. Thanks for being on the podcast, Alyssa.
[00:02:43] Alyssa Whitcraft: Thank you for inviting me.
[00:02:45] Craig Macmillan: You're involved in a whole bunch of different projects and consortiums and programs mostly around remote sensing and agriculture.
[00:02:53] And you're excited about a number of different things in your field. What exactly is your field? I think it's a good place to start because I think a lot of people don't understand what it is.
[00:03:01] Alyssa Whitcraft: I'm a geographer, which is basically the world's oldest discipline. We use the lens of space and place and location to understand the world. And knowing that things that are near to one another tend to have more in common than things that are far from one another. And similarly, we know that where you are in the world matters for all sorts of different things. And that's really the lens through which I see and understand the world. Specifically within geography, because geography is a very broad discipline, my expertise is in using satellite data and other Earth observations to understand what's happening across the world in principally agriculture. I've done work in the past in forestry as well.
[00:03:47] Craig Macmillan: What kinds of things does this field have coming in the future? What are the things that you're most excited about in terms of all the different work that you're doing?
[00:03:55] Alyssa Whitcraft: Would it be helpful if I gave a little bit of history, or is that too much info?
[00:03:59] Craig Macmillan: . Please, please.
[00:04:01] Alyssa Whitcraft: Sure. So a lot of people don't realize that satellite data has been collected of the Earth's surface since 1972. NASA launched its first satellite back then, and one of its first applications was agriculture. It was really for looking at global forecasting, production forecasting, and things like that in areas where We couldn't gather statistics like the USSR, for example. And so that was very early.
[00:04:29] They thought, hey, we really need to understand what's happening with the global food production, global food supply. What kind of prices are we going to be able to get? Those were the very earliest experiments. And a lot of years have passed since then. It's 52 years now. That particular satellite was called Landsat. Well, it's called ERTS 1. It's been, renamed Landsat 1 in hindsight and they've just launched Landsat 9 two years ago. So we've really, we have a lot of series of it now with continuity of data for 52 years from that satellite, that mission alone. there's a huge plethora of other types of data though that are also collected. Landsat, for example, its characteristics are, it passes over the same place every 16 days at about 30 meter resolution. So 100 feet by 100 feet, about a football field, and then there's other satellites that pass over every day and they might have much coarser spatial resolution. So 250 meters by 250 meters, for example. And then there's also recently, because storage is cheap and the Internet is fast, there's a proliferation of these very fine spatial resolution satellites where you can tell almost down to the plant level.
[00:05:38] Definitely tree level, what you're looking at, that's quite fine in resolution and still have some degree of rich spectral information. And what I mean when I say that is basically everything around us is reflecting light all the time or emitting light. And we only see a little tiny piece of it, the visible spectrum.
[00:06:00] That's why it's called the visible. But there's so much richness, on both sides of the visible spectrum. So longer wavelengths and shorter wavelengths, and they tell us all kinds of things about what's going on with a surface. we see vegetation as green because that's what it's reflecting. But there's other things in near infrared that can tell us about vegetation health. Or sort of mid range infrared that can tell us about water stress, things like this. And so now we have more and more spectral information, more and more frequently and finer and finer spatial resolution.
[00:06:35] So our ability to see a great deal of detail has come a really long way. And still just like kind of any instrument you use, your ability to do something useful with it is contingent upon its quality and also the quality of the kind of science that you use to interpret the data and turn it into information.
[00:06:58] Craig Macmillan: What kinds of information is this data being turned into? And on what kinds of or agrosystems?
[00:07:06] Alyssa Whitcraft: All over the world. There's two broad classes of satellites. One is called polar orbiting. So it's going around the poles and it returns to look at the same spot every, you know, it's governed by its orbit and a couple of other things. I said Landsat was 16 days, for example and others can be much more frequently or even longer. So that's one kind, polar orbiting. The other type is geostationary, which means that as the earth turns, it's always looking at the same spot. And that's what most of the sort of weather satellites are. So that's why you can get really like frequently every 15 minutes, like a radar image, for example. all that's to say, like a lot of the satellites we use are polar orbiting, and that means it's not biased toward only collecting data over the United States.
[00:07:48] It's collecting data all over the world. In the past, because. storage was expensive. There wasn't very much storage capacity on the spacecrafts. You couldn't store it all. They used to have to select which images they were going to capture. So it might be passing over a surface, but it wouldn't turn the camera on. And only about, I want to say 2012, 2013 was when Landsat started acquiring almost every single opportunity. And not just capturing something like A third of the daylit scenes that could capture every day. so all that's to say, we now have like so much rich coverage the last 12 or so years with that kind of satellite. So that means like we're getting observations of the earth's surface where everywhere agriculture is grown at least every day, depending on the type of satellite you're talking about. And even for the finer resolution ones, you're getting it every day. 10 days, maybe once you are to 20 days once you account for cloud cover in a lot of areas.
[00:08:44] Craig Macmillan: what kinds of decisions can people make regarding how they farm based on this kind of information? And my understanding is that this is public information, is that correct?
[00:08:53] Alyssa Whitcraft: What I talked about was sort of where you can collect information. It's all over. It's not you know, biased toward any particular region per se. By virtue of that, it's not necessarily biased toward any one crop because it's collecting all those data. So those observations exist, but our ability to turn them into information is contingent upon how much we've studied that, that item. And, and how much what it, the light that it reflects in the satellite picks up on is related to whatever it is that we're trying to study. So that's to say if a satellite only collects visible information, then we're not going to be able to talk about sort of some of the items associated with chlorophyll content and like health of the plant. Or if it doesn't collect the long infrared or mid infrared you're going to miss out on information about water, things like that.
[00:09:41] And that's just kind of a simplified answer to that piece. And so we're able to collect all kinds of variables. In my work, we've called them essential agriculture variables. they're basically core building blocks, variables that we can measure and infer about the earth based on satellite data about the state, what the change has been over time and what the forecast is to the future.
[00:10:02] We can look at, Hey, what kind of crop is being cultivated here right now? We can see how has that changed over the last 10 years? We can look at, okay, this is the current condition. What's the forecast for harvest this year? different things like that. We can also do within season detection of certain stressors, biotic and abiotic stress.
[00:10:22] So you know, can be viral, fungal, bacterial diseases water stress that can help with precision kind of irrigation scheduling. We can also look at you know, when you couple that with like short term weather forecasts, you can see, okay, there's going to be really high demand evaporative demand. And so we need to think about maybe irrigating or doing something in advance to prep the vegetation for that. You can also use it for nutrient applications. So, this is primarily in row crops so not really vineyards per se. But, we can take a look at what the current nutrient status is. Nitrogen, if it's nitrogen deficient, then you are only applying what it needs and not too much. Same goes with pesticides. You're not just doing blanket spraying. You can do early detection and mitigation. With nitrogen, you only apply how much is needed and where it's needed, which has important environmental benefits. It also helps the farmers sort of bottom line, not wasting money. And also in terms of a fertile excess fertilizer being applied and also not leaving money on the farm by not applying enough. It can be really helpful in kind of zeroing in on what intervention needs to be done and what you can prepare for at the end of the season.
[00:11:32] Craig Macmillan: I'm just thinking through this, so you would have to have some crop specific, and maybe even region specific on the ground work in order to make the connection, the correlation between, I'm getting this reading, and then this is what's going on with the plants.
[00:11:47] Alyssa Whitcraft: Yes. Yep. That's completely accurate. And I'm really glad you said it because there is a perspective on satellite data that it's magic, that you just take the image and you have the information. And that's just like not really how it works. Now we're getting more and more sophisticated models out there, but all models have to be trained on something. And just because I've trained it on a ton of corn in Iowa doesn't mean it's going to work on corn in Argentina. Like that's just not necessarily how these things work. some people call it ground truth. I prefer to call it training data, validation data. you know, in situ site data, things like that, comparison data. And the reason for that nuance is just to say that there is error in all measurement. So just because if your scale is calibrated wrong and you say, this is, this was my harvest, this was my yield, then that's not necessarily ground truthed see what I mean? So, and I think that that's an important point to make because we're trying to add an additional piece of measurement to the picture, right?
[00:12:48] It can give you more frequent. more coverage deeper spectral information. It can a lot, but it's a piece, it's a component of a multi source decision support system. We say like garbage in garbage out on the remote sensing side of things. Our observations are very good, but you know, we're talking about hundreds of millions of dollars of engineering in the sensors and the satellites to go up into space. So those are incredibly high quality and the space agencies who fly them they do a lot of expensive CalVal, it's called, so they go and they make sure that the instruments like, you know, The analogy in your kitchen would be you stick your thermometer in boiling water to make sure 212 Fahrenheit or 100 degrees Celsius is exactly what your thermometer is picking up, right? So we do the same thing with satellites. that's great for the reflectance or for the wavelengths, but that's not information. So then what we go out, we might take some tissue samples. To understand what's happening with nutrients with pest and disease stuff, some soil samples for that purpose. Or for some of the more like workhorse, what we've been doing with satellite data for a lot longer, those are more novel applications. The lot much longer is what's growing where where it is. What's the season. Like why is it. Kind of just at the early part, is it flowering, reproductive, is it toward harvest and then also yield.
[00:14:09] And so we go out, we take crop cuts, we do things like that, then we calibrate our observations or our models against those data, and then we can run a predictive model that can tell us for the same site in another year, or more commonly you take it from that site and then generalize it. to where you have satellite data that are continuous, like so you have a whole an image, but you don't have any training data from this vineyard over here. So you take the training data from this vineyard and see if you can use it to identify what's happening in other vineyards. And then you assess, how well did I do off of another set of data that's from the ground.
[00:14:46] Craig Macmillan: And so I would imagine that that kind of work is done extensively in agronomic crops, or what we might call staple crops, you know, rice, maize, soy, things like that, wheat. But you can do this with specialty crops as well. You mentioned vineyards. If there is interest and if there is funding, we can do this kind of work and bring vineyards into this this, this kind of process, this kind of science.
[00:15:11] Alyssa Whitcraft: Yeah. I mean, you're spot on. Like I said earlier, the earliest applications of satellite data. Were in kind of global production forecasting with the reason being that wheat prices, for example, are incredibly correlated with conflict. So as wheat prices go up, you see more human conflict. And so these are the huge drivers of global trends in prices, in food security, all these kinds of things that are really important to track. And so the, you know, the early app applications were really for that type of crop and for very large scale forecasting in the sort of 80s, 90s was when you started to see some of the precision management. So on farm information but perhaps not as much as people hoped for in in this kind of satellite world, there was a lot of unsuccessful startups and, and things like that. I think the big reason for that is like, if you're going out and scouting your 10 acre vineyard, like you can generally walk it. It's not a big deal. You're not driving a combine through. My family's in the wine business and I grew up walking vineyards with my dad and taking tissue samples and taking fruit samples and doing things like, it was just a part of the day, you know, if you're farming 10, 000 acres, that's not viable.
[00:16:30] And so you're, you have, million dollar combine to these days and things like that. That's something with autonomous driving, you can program a great deal of information into it. sort of like historically, there just wasn't necessarily the, like. The demand for what satellite data could offer, you know, it was focused on kind of like yield and nutrients and water.
[00:16:49] There just wasn't the same use case in, in specialty crops. In a lot of ways, especially since some of them are growing greenhouses. So like, we're kind of out of luck with that. And so, yeah, whoops, but that things have just changed. We have better satellites now that collect more information more spectral information, higher spatial resolution, more frequently, we can process so much more data now, which means.
[00:17:14] we can kind of just keep throwing more and more data at a model until it picks up some signal that we never could have anticipated. That's kind of the basis of machine learning or artificial intelligence is that you just keep going like feeding it until you see if something comes out. That also has its own problems.
[00:17:31] Pretty funny fails AI. I think we've seen before the models get overtrained and it's very. clear that they don't work once they're over trained. They, they spit out like a baby with three hands AI image. And you're like, that's not, that's not right. Or I saw a matzah ball on a plate. It was like, rather than like a soup dumpling, it was like a tennis ball that was like matzah colored. I was like, that's not right either. You know, it's funny things like that. So the same thing can happen when we're looking at, you know, the earth's surface as well.
[00:18:00] Craig Macmillan: you are executive director of NASA Acres. That name has come up in a couple of other interviews. Could you explain, , what NASA Acres is and what you folks do?
[00:18:09] Alyssa Whitcraft: Yeah, sure thing.
[00:18:10] So NASA Acres is NASA's U. S. focused Applied Sciences
[00:18:15] So why, that's kind of a long title, NASA is principally a research agency. Now, it's not it's not USDA where it does farm services or loans or reports on statistics and agriculture. It's famous for people putting a man on the moon and missions to Mars, but NASA has this whole huge earth science division. within that, there's you know, the, the component that's dedicated to launching the satellites and making the data really high quality. And then there's an accessible data, high quality and data accessible. And then there's sort of like the core foundational research, which is. We've never used satellite data to measure this thing before, or we have used satellite data, but now we're just going to apply it elsewhere and do a study that results in a paper.
[00:18:56] So we learn a thing. That's research and analysis in NASA, and then there's applied sciences and earth action, which is, it's kind of new manifestation in NASA, which is like trying to take this data and really make an impact, really get the information, the data, the tools in the hands of people who are addressing, in our case, agricultural challenges.
[00:19:19] So that's farmers, that's ranchers. That's people in the ag value chain that's ag retailers, all the, I mean, there's a whole bunch of people in here who can benefit in some way from this data. And our job is to work with them to advance the science as much as possible because NASA's brand is really like quality, right?
[00:19:39] And then, but also neutrality. And so we kind of just try and lift. the floor, so to speak, make the quality as good as possible, advance the science, and then hope that the private sector that's out there that's serving people in agriculture can sustain the services or, and, and really be adding value to people in agriculture long, long after our projects end.
[00:20:00] Craig Macmillan: And so that, that's going to be where the next link is, is the private sector picking up this information, this data, and then figuring out how they can use it for their client base, maybe for a specific crop or a specific region, and then we can we'll see some development there. we've seen with like material science, I think is a classic example of that, you know the space program resulted in a lot of advances in materials that now we don't even think about. They're part of our everyday life,
[00:20:27] Alyssa Whitcraft: Yeah, like the blankets run a
[00:20:30] NASA, more than just Tang, you know, when I'm trying to like get across to people that, the planet we study most is Earth to quote Karen St. Germain, who's the Earth Science Division Director for NASA. I mean, material science is a really good example, but we have it so much in all these things that like, be them weather and climate services That's, you know, Noah's job principally to create the kind of forecasting models that are pushed out when we're talking about the United States.
[00:21:02] There's people all over the world doing it and then like weather channel or weather underground or whatever, build services on top of that. And then that's like what faces the consumer. So it's all kind of a part of an important chain. And in fact, NASA is in the background collaborating with Noah on this information as well. for us in the agriculture side of things NASA harvest, which still continues today as NASA's global agriculture applied sciences program. But from 2017, when it started until 2022, it was the whole kit and caboodle. So both us global international, the whole thing. And then they split the programs.
[00:21:39] So into Acres and Harvest. I was the deputy director and program manager for NASA Harvest from when it started until I took over the helm and founded NASA Acres in 2023. NASA Harvest, there's a great example of commercialization or of, of really strong collaboration with the private sector. Which is when the Ukraine war began there was obviously a huge hole in information all of a sudden about what on earth was going to happen with the food that comes out of Ukraine, which between Russia and Ukraine, it's 30 percent of the world's wheat, wheat's very correlated with conflict to begin with. And there's certain partners who are a hundred percent reliant upon imports from Ukraine and or Russia of wheat. , you don't just go drive down the street to the next grocery store and pick up your wheat. Like this is billions, trillions of dollars of movement that can't pivot overnight. So the potential implications were massive. And the more information you have earlier to plan for that, the better. And that's where satellite data came to bear. You couldn't send field agents out when there's an active war happening to be like, what was planted? Is it growing? Are farmers? Applying nutrients.
[00:22:50] Is it going to be harvested? Things like that. NASA Harvest partnered with a number of organizations, but one was a private space company called Planet who collects sub meter and three meter data. daily with they have many, many small satellites and so they're, these are not the three, 400 million satellites that NASA flies.
[00:23:08] These are much less expensive and they can fly way more of them. They're much smaller. They're a very different satellite. But they're great for getting high spatial resolution often. And when you can't go out and collect ground data. to do training on your images. Was this planted? Was this not planted?
[00:23:25] This appears to be this crop. This appears to be this crop. Satellite data of that kind are very helpful. And so then we would use that to train some of the other satellites that have perhaps richer spectral information or other qualities that we might look for in a certain analysis.
[00:23:40] And because we had this partnership with Planet, they were going out and collecting the data. We were able to do this analysis. talk about, you know, what we expected to see in terms of wheat harvest that year and sunflower and corn and rapeseed and all these really critical crops that Ukraine exports and help us prepare and mitigate any potential food security crisis and then Planet.
[00:24:03] On the flip side, they've suddenly made a huge impact with their data. And they've additionally been able to, you know, we do a lot of work on the. nitty gritty of the engineering of radiometric calibration and things like that. We also can support them in improving their imagery. And then now they have a use case in agriculture and all these different kind of things by partnering with us. But we've also advanced the models and the science and the knowledge that's all a public benefit. And so that's like a really lovely investment from the federal government that kind of has this big societal benefit, but then also supports the private sector and continued innovation and services.
[00:24:37] Craig Macmillan: in this case, it allows for the prediction of what may be available right?
[00:24:43] Alyssa Whitcraft: Yeah. In that example, for sure. The war broke out in February and the winter wheat harvest would have been, gosh, like may to June. You're looking to see how was the, was this coming back after winter? We're, what was the condition of the crop at a baseline? Were people able to apply nutrients of any kind? And once harvest time came. Were people able to go down in the field to harvest or did they not do it because they had been killed or evacuated or because there's unexploded ordinances in their field and things like this.
[00:25:13] And so that was really the beginning of the analysis and then it, it continued for other crops into the future. And it's a really rich ongoing project about which you can find copious resources online.
[00:25:26] Craig Macmillan: how are we doing on, on those areas? Are there people that are stepping up in the private sector to work on that.
[00:25:31] Alyssa Whitcraft: Definitely. Yeah, there are. The public sector, you know, my side of the house is too. but it's interesting. it's an interesting point because we focus so much on agronomic crops. We've done that because there's a really clear reason to invest public dollars. I think the very early stage collaboration with the private sector for specialty crops is much more critical than it was for these kind of big agronomic crops. So that means from the odd outset. the projects need to have very engaged partners from the private sector. It might be in the form of just working directly with the vineyard so that they can kind of maybe collect some of the ground data or if we're developing a tool, they can kind of like test it and provide feedback, things like that.
[00:26:14] But then there's going to be other circumstances where we might be trying to use a compendium of information. So you might be using some soil sensing to look at water status. But it's like, you can't place a million of them in your field. So, you know, you might take the benefit, the accuracy, the depth that you get from those expensive and ground instruments, and then try to pair them with the satellites and then build like kind of a hybrid measurement system.
[00:26:41] You get the benefit of the update frequency the satellites and the spatial coverage, of course. And then you get like the really good quality. measurements within the field. we've seen a lot of burgeoning partnerships in specialty crops and of course also agronomic commodity crops as well, but where we're trying to look at a hybrid network of in ground sensors or canopy sensors or drones. side canopy robots that my colleague Katie Gold, who was on your, podcast before, she uses these robots, Katie Gold and Yu Jiang, her collaborator at Cornell to, to sort of build toward the long term adoption of, of these, actually not even long term, to build toward the short and medium term adoption of these things, because that's real, it's really going to sustain them, NASA projects. typically three years acres and harvests are each in five year kind of increments harvest was renewed and For its global work and spit off its domestic work. And so hopefully we will be renewed as well But it's not the design of federal research to like provide every service forever We need to work with the people who need the information Because they're gonna tell us what to do and what like what matters to them You and then we need to work with the people who can kind of own the services long term and maintain those high touch relationships with their customers, growers, ag retailers, whomever it might be.
[00:28:04] Craig Macmillan: Spain, places like that Australia?
[00:28:06] Alyssa Whitcraft: You this is an area I'm definitely less comfortable talking about. within NASA Acres, we really only have Katie and you's project that's in specialty crops. And that's principally just by virtue of all the things I described. It's really only been the last four or five years that this stuff has started blossoming. And even within Katie's project. She's not using satellite data really, right now, she's done some demonstration stuff. We're preparing for a NASA instrument to launch in 2028. And we're doing years of preparatory work. NASA has an airborne fleet. People don't know that. And it's collecting very similar data to what will on this satellite SBG. Also, there's a sensor mounted on. The International Space Station called EMIT that also collects similar information. So we're already using that, but we're kind of like priming the pump for primetime, right? So Katie is very, Katie is like a very kind of ahead of the curve kind of situation person. The spectroscopy of the laboratory stuff, we all, we all know that it's been around for a long time, but the imaging capability to do it outside is novel. And so she and Yu are kind of working together on that. I don't have another project in my portfolio that does that right now. We are looking at using those data similarly, the hyperspectral is what it's called, data. We're starting to try and build use cases in rangeland monitoring as well for rotational grazing.
[00:29:33] So looking at forage quality, it's not just a matter of whether the biomass comes back, it's whether it's the right biomass, so the right mixture of different crops. If you've overgrazed an area, you'll just get like the one dominant. type of grass will come back, and that's not very nutrient dense, and it's not very sustainable, it's not very regenerative. If you don't overgraze an area, then things will grow back in a more balanced way, and that's something that we're trying to explore, how well satellites can pick up that heterogeneity in the landscape. That's an example there. I'm aware of some work in sort of olive groves in Spain, in Italy And I know there are some companies who have attempted to do kind of proxy measurements of shade coffee and cocoa. Very high value crops, but you can't see them because they're under the canopy of another tree. And there's been a lot of different experimental ways of trying to get at that. But in terms of my understanding of how successful those different cases have been. It's a little outside my wheelhouse. It's pretty novel. and yeah, I mean, I, the, the thing about being an applied sciences program, we're not the foundational research RNA. So what that means is like, we've got to kind of see the science demonstrated fairly firmly for it to move into a major part of the portfolio.
[00:30:53] That said, like there are some projects in my portfolio that are higher risk or that like, you know, that delivery might be a few years off because of the lack of instrumentation. And there are some stuff that's more experimental, but where those are the case like that Rangeland project or Katie's project That's because we have super engaged users already. So there's ranchers who are at the table for another purpose. Katie is, you know, an extension agent for Cornell working with grape and apple growers, and they want to know how to manage this.
[00:31:23] So she already has engaged parties. So having the satellite stuff be like maybe a little bit more nascent and its development cycle is okay versus, you know, where we don't necessarily have the strongest user. identified and partnered already, we're kind of relying on the more mature applications and starting to kind of transition that stuff out more quickly to broader audiences.
[00:31:45] Craig Macmillan: How can the wine grape industry or other crops, support this and encourage research in their particular area?
[00:31:54] Alyssa Whitcraft: There's legwork on both sides meaning that we need to be with the communities we live and work in. Thank you. to get those people involved in what we have to offer. So it's like there's a trust building component, there's an awareness building component and then there's also just the participate if somebody contacts you about being in a study or, you know, by word of mouth, Oh, this vineyard down the road is doing it.
[00:32:17] Like, maybe we'll do it here. I trust that person's discretion, so I'll do it here. Collaborating and being active in that research from the NASA acres perspective is, is really important. And more than just really from the NASA acres perspective, from really the kind of, you know, we're neutral, we're trying to build quality, we're trying to raise the floor.
[00:32:36] So even if you come, you know, you come through us, we hopefully make things better, which feeds back benefits to you in your, in your operation, but also to your kind of broader industry. So there are some vineyards, for example that I have personal relationships with from my whole life. And when Katie and I started collaborating and, you know, just generally sharing passions for a number of things, including wine and remote sensing, She asked if I had any, you know, friends who would let her take tissue samples who thought they might have particular diseases or were just curious to collaborate so that she could kind of do this proof of concept of these technologies and do these studies. And I was like, yeah, probably. So I just shot a couple of friends text messages and they were all like, sure. And the thing is, is like, they know me, right? And so they know that I'm not going to Never do anything intentional to bring harm. And I certainly would also go work very hard to make sure that even something I hadn't foreseen was protected. And I think that that's actually so critical, probably in every industry, but I'm most comfortable in agriculture. Like these are strong communities of trust that are built up. You know, you knew my dad and when I was 15 he had a major surgery in kind of mid, late August which coincides nicely with harvest, the beginning of harvest.
[00:33:57] Craig Macmillan: Yeah, the wine grape harvest in california.
[00:33:59] Alyssa Whitcraft: exactly. My dad was a winemaker in in Santa Barbara County, and that's where I grew up And I grew up in the winery so yeah when I was 15 He got he got really sick And he had to have a surgery and he was in the ICU for like a week and after that like it takes a while to recover so people that he had mentored, people who he had been close with for, you know, 20 odd years, 25 years in, in the region just kind of stepped up and processed his fruit, you know?
[00:34:28] So one, you miss one harvest, you're donezo, you know? Like that's just not how things work in the wine business. And my brother, who's now the winemaker, was only 19 at the time. So like, technically he wasn't even old enough to drink wine legally, but like, you know, he was there kind of. Running the ship with, you know, the huge support of these family friends who made it happen. So all that's to say, like those trust networks are everything in, in agriculture and everything in sort of agri food and like I said, probably other industries too, but I just don't know them. That's certainly the case in agriculture. And we're not going to make any like progress unless we build those trust relationships.
[00:35:08] And then since we can't meet everybody face to face, we need you know, those people to then be the hinge points to bring their, their kind of collaborators, colleagues, friends business partners, whatever, to the table to tell us what they need, to tell us what they want, give us feedback on what we've done and then work with us if they see value.
[00:35:27] Craig Macmillan: Yeah, I'm thinking of there are a number of organizations in the United States, in the wine industry, that fund or promote research on particular topics, and I can see there might be an opening there. you know, talking about trust, folks that have gotten awards, farmers that have been collaborators on these projects. I think it's a good place to start. For these new technologies. I think it's an interesting idea. I hadn't really thought about it that way. And I'm definitely going to take, take that away with me when I go to some of, these meetings. , and some of these, , some of these, , review, , committee
[00:35:57] Alyssa Whitcraft: Related to that, so one of the things we're just beginning to kind of explore the logistics of how we would implement it is identifying sort of farmer champions or kind of innovation partners. I don't know exactly what we want to call them, but they're people who are like amenable a collaboration
[00:36:17] , everybody only has so much time. So it takes time to do these things together. So if you have like a real passion or a real interest, it's something you might more willing to do. It helps us do it. the most good the most quickly. , so we're kind of looking at creating this kind of collaborator farmer innovation partner kind of thing where we work, you know, on their farms, they kind of give detailed feedback.
[00:36:38] They serve as different kind of hinge points, , to meet people in their community and really be champions we're doing, but also like not just be our hype guys and hype girls out there, but just be like, Hey, what you're doing makes no sense. Or like your aunt, you know, that's great that you created this capability.
[00:36:55] That gives me a forecast every week. I need it every day. Not useful to me. Things like that. So the frank feedback, , early adopters, but high touch early adopters, people who really are passionate about benefiting their industry and communities.
[00:37:10] Craig Macmillan: the state of the, world right now you've mentioned nations, lots of different crops, lots of, different technologies in your work and also kind of in the future, what's happening now to move all of this forward and where do you see it going?
[00:37:23] Alyssa Whitcraft: not to you know, date myself, somehow I'm one of like, the more se, I don't know senior is the right word, but like I'm no longer the young in this world. And so I've been around long enough that I started remote sensing in remote sensing of agriculture before.
[00:37:39] was really on an upward trajectory. Things have changed the last 15 or 16 years. But when things were really was the food price spikes in 2008 and 2011 that led to huge, push over a billion people into chronic food insecurity. It's horrible. So let's launch this called GeoGLAN Geo Global Monitoring that's going to use satellite data to give us information about, crop production globally.
[00:38:05] Some 40 odd years passed when. NASA first started doing it with Landsat. Within that GeoGLAM initiative, I was program and still in program scientist one of them. And my specific role is I work with the different space agencies in the world on developing new missions for agriculture.
[00:38:20] I basically advocate for the agriculture community to make sure we get the observations we need to do our analyses. what started out is very much this like food security, markets and trade kind of stuff. Segwayed over time, as the field grew, changed, ag tech blossoming, whatever it might be.
[00:38:38] And around 2019 2020 was when my specific focus started turning a little bit more, not stuff, but started zeroing in on the kind of farm level stuff. Because I got really interested in the way my discipline, my methods, my tools increasingly being used in the sort of sustainable ecosystem services marketplace.
[00:39:01] Without there being a whole lot of kind of methods, development, calibration, validation, like, yeah, we can, you know, create a map, but is it any good kind of thing? Or yeah, we can create a model, but does it work? People were coming to us with the NASA harvest name and the NASA kind of name and saying, can you validate this?
[00:39:17] Can you do And we all felt pretty strongly that our role was really to lift. votes for everyone. That's where we zeroed in on that topic wise in the Harvest Sustainable And Regenerative Agriculture Initiative, which we call Harvestera. I'm also the executive director of that. all these tools have advanced.
[00:39:35] The need has advanced. The audience's kind of openness has advanced. The kind of critical need for us to use agriculture as a tool belt to restore ecosystem health, soil health in rich communities and fight climate change, it all kind of needs to start at a baseline of understanding where we are and where we can go.
[00:39:54] And so I see satellite big part of that. This is all kind of coming together now. We still need the public sector's investment in terms of high quality observations. access, the lifting of the science in order for that to really take flight and be reliable and be good. that work that I've done for 12, 14, something like that, 13 years now through GeoGland with the space agencies has recently been morphing, into not just advocating for food security and market applications, but also saying, you guys, we got to think about ecosystem services.
[00:40:25] We have to think about sustainable management. Got to think about the precision. And so the space agencies are now receiving this message that there's a whole new set of value propositions for their data, but also the public sector pushing that direction.
[00:40:39] And then we like kind of push together. Toward impact.
[00:40:42] Craig Macmillan: one message that you would want to tell wine growers regarding this topic?
[00:40:46] Alyssa Whitcraft: Gosh, one message.
[00:40:48] Craig Macmillan: Two?
[00:40:51] Alyssa Whitcraft: Oh man, I guess you know, I think what a lot in my field don't think a lot about is quality Of the crops. We tend to think about quantity. Of the crops. and as a result, we can kind of answer use the wrong, use the wrong approach, answer the wrong question. And for specialty crops and I think, you know, what's finer than fine wine in, in terms of how much finesse you have to have from the 25 plus year old vines through bottling.
[00:41:20] What kind of needs a higher attention to quality I think that. for the grape growing community, particularly for wine and fine wine. they could maybe help shape this and push this, put out the demand there and say like, I don't need you to tell me how to absolutely maximize, make the like juiciest, wateriest, highest volume of berries.
[00:41:40] Like I need to know how to make the best quality. I need to know how to prevent losses related to extreme weather. I need to make sure I don't have my die that, I've been cultivating for so long to build these beautiful old growing and all that, they're more important than maybe they realize they are in this space and could push to really move our science and usership toward quality more than perhaps we have historically.
[00:42:03] Craig Macmillan: and I really appreciate you sharing that. This has all made me think about an interview that I did recently with an extensionist from Texas A& M we were chatting after the interview actually about climate change. She said, there is not a single grower in the state of Texas that is a climate denier.
[00:42:22] Everybody sees it. It is getting hotter. And things are changing and they're going to have to change. There's no doubt about it. And that reminds me of changes in other agro systems. over time whether it's changes in the way the soil fertility is, or changes in rainfall, or changes in disease patterns. I think there's applications, especially in areas that are suffering extreme stresses now, that'll apply to places that'll suffer extreme stresses, maybe a little bit later.
[00:42:49] So I think that's a great message that we can bring to These programs say, Hey, we need. And here's maybe how can we do it? How can we benefit from what you're already doing? I think that's a great message. Where can people find out more about you?
[00:43:01] Alyssa Whitcraft: if you want to find out more about NASA acres, you can go to org. If you want to find out more about the Harvest Sustainable and Regenerative Agriculture Initiative, that would be HarvestSara. org basically any program I've said today, you can just put a org at the end and it'll work. And if you want to learn about my family winery, it's WittcraftWinery. com And just shout out to my dad, my mom, and my brother for kind of sparking and maintaining my love of and interest in food and wine.
[00:43:33] Craig Macmillan: Yeah, And just on a personal note your dad, Chris was a mentor of mine. It was one of the first winemakers That I worked side by side with and had a huge impact on me. Especially around the idea of quality.
[00:43:43] Alyssa Whitcraft: Okay, so not to totally digress here, Maybe it's germane to the topic, which is I was pre med at UCLA. And I took a a geography general ed course called people in Earth's ecosystems just to fulfill a gen ed requirement and fell in love. And that professor bonded. and he did a lot of remote sensing of tropical I took his remote sensing class. We were supposed to. pick a and design it. And the picked was trying to. Compare every single metric that we could derive from satellite data for Conti, with, with some vineyards that my dad sourced from at the time so like Bien Nacido. Obeying these different vineyards and trying like in compare, I mean, it was the polar opposite of a robust study. I was like 20 and it was my first remote sensing class, but it really like capped my interest because trying to understand. Obviously there's the climate pieces to some degree, there's the soil pieces, but you know, my dad was the first or one of the first at least to do the blocks designation in wine.
[00:44:45] So he had N block and Q block and Bien Nacido. And I was like, well, what was it? characteristic that made them sort of different? Could you come up with that in a way, not that we should quantify and sanitize everything because there's certainly a je about these things, but like, what is it that creates quality, ?
[00:45:01] , and what of it is sort of biophysical in nature and could be measured and that kind of really sparked the interest that shaped the rest of my career.
[00:45:09] Craig Macmillan: That's fantastic. I really want to thank you for being on the podcast. Our guest today was Alyssa Whitcraft. She's executive director of NASA acres, fascinating conversation and tying together some pieces from previous podcasts. Yeah, just thanks for being a guest

[00:00:00] As a member of a sustainably minded ag business, you have the potential to shape the way people view our food system.
[00:00:07] Welcome to marketing tip Monday with SIP Certified. We know that customers are looking for wines labeled as sustainable. While our longer-form episodes help you learn about the latest science and research for the wine industry. These twice-monthly micro podcasts will help you share your dedication to sustainable winegrowing.
[00:00:27] There is a dramatic difference between how consumers and producers understand sustainability. While, both groups have positive perceptions of sustainable agriculture. The general public has a much more limited understanding of it and even ranked sustainability as one of their top four least understood terms.
[00:00:48] Fostering a shared understanding from farm to table is key to turning sustainability into the norm. With that comes a healthier future for people and the planet. Part of the problem is that farmers themselves often don't have the time. Or the platform to communicate directly with consumers. But an educated and informed hospitality and sales team that's you can bridge the gap. And an easy way to start is by educating your team on what it means to be a sustainably minded business.
[00:01:19] Tolosa winery in the Edna valley of San Luis Obispo, California created a unique way to both teach their team about sustainability and involve them in their efforts. This week's marketing tip tells their story.
[00:01:33] With Tolosa is three PS groups. Employees were given the opportunity to experience sustainability firsthand.
[00:01:40] Each person could join a group that focused on one of the three pillars of sustainability people, planet and prosperity.
[00:01:47] Each of the groups would take their area of focus and work together to find ways to improve the businesses practices.
[00:01:53] First off the people group.
[00:01:55] This group focused on encouraging staff. Engagement safety communication and more. They looked into wage scales to ensure the staff was receiving fair pay And analyzed and improved safety procedures.
[00:02:08] Second up is the planet group.
[00:02:10] This group taught Tolosa's staff, new methods for recycling and composting, both at work and at home. When the company wanted to expand its solar field, the planet group researched soil profiles and growing conditions. On the company's property to identify the area that was least hospitable to vines. So it could be used for the expansion.
[00:02:30] And thirdly, the prosperity group,
[00:02:32] thanks to this group Tolosa, reduce their water by hundreds of thousands of gallons. Member's designed a water nozzle that eliminated the wineries open hose, water use. In fact, the nozzle is so good. It is now mandatory. Josh baker CEO says on average, this one small change resulted in some 380,000 gallons of water savings annually.
[00:02:56] While, participation in the groups is always optional. Employees were enthusiastic to join Josh notes, that the level of staff involvement. Was a bit of a surprise. People chose to take the extra time to be a part of it.

If you are dealing with vine mealybug in your vineyard, you are not alone. Kent Daane, Cooperative Extension Specialist at the University of California Berkley studies different types of mealybug populations across the globe.
Kent covers organic and conventional strategies, ways to increase the presence of generalist and specialist natural predators, and the importance of establishing refugia for beneficials.
His latest work focuses on area-wide management tactics. Looking to the European Grapevine Moth eradication program as an example, Kent sees an opportunity to decrease vine mealybug populations through neighborhood driven monitoring, trapping, coordinated sprays, and mating disruption.

Transcript[00:00:00] Craig Macmillan: Welcome to Sustainable Wine Growing with Vineyard Team. Our guest today is Kent Daane. He is a Cooperative Extension Specialist with the University of California, Berkeley, and he works primarily out of the Kearney Agricultural Research and Extension Center. And today we're going to talk about a number of topics.
Thanks for being on the podcast, Kent.
[00:00:17] Kent Daane: Craig, thanks. I'm happy to be here.
[00:00:20] Craig Macmillan: Let's dive in on one pest that everybody's interested in, continuing to be interested in, and you may have some new insights or newer insights on this. Let's start with mealybug management. Kind of what's the state of the art in that topic right now?
[00:00:33] Kent Daane: Yeah, that's been the number one question I've been getting for many, many years now. It is an invasive pest. We know it came in, probably being brought in by a grower down in Coachella Valley. It has since spread into the San Joaquin Valley, Central Coast area where you are, Napa Sonoma, and it's been found now in Oregon.
Just like Napa, Oregon has attempted an eradication program. And probably just like Napa, most likely it's not going to work. It's a very, very difficult insect to kill 100%. I mean, I can come up with all kinds of different programs, soft programs, hard programs, expensive programs, inexpensive programs, where I can suppress that insect pest. It's very difficult to remove it from a vineyard. And that becomes important when you think about the kinds of damage we're worried about in Central Coast wine grapes.
Pretty much anywhere where they're looking at grape quality. But especially in the cooler regions. So, this insect, this mealybug, is one of many mealybug species. that is a vector of grape leaf roll associated viruses. And this is the primary reason it grows to such high pest status. So for the most part, the growers can knock its levels down far enough that it's not in the grape clusters or it's rarely found in the grape clusters. That's more of an issue for table grape growers. It's a cosmetic pest. When you look at some of the Regions in the San Joaquin Valley where they're growing a lot of table grapes Kern, Tulare, Kings, Fresno, counties, there's enough heat accumulation and these grapes are harvested early enough in the season that they can still build up their Brix. They can still get a very good grape to market. Even when there's some vinely bug on the vine, they just don't tend to be as impacted by this leaf roll pathogen as our wine grapes.
When you get into regions like San Luis Obispo, Napa, Monterey, Oregon, where they really are trying to hold those grapes on the vine for a longer period of time, trying to build up the bricks levels. That's where this. pathogen causes so much damage.
[00:03:06] Craig Macmillan: most of our growers are already going to be familiar with this, but what kind of damage does the vine mealybug cause? It's so, so terrible.
[00:03:12] Kent Daane: So the vine mealybug, besides being a vector of this pathogen, is also a direct pest of the grapevine. It can feed on the roots, on the trunk, on the leaves, and in the fruit. When this first hit California, we were working on it primarily as a San Joaquin Valley pest. growers that were putting on, you know, the products of the day dimethylate, lanate. If they were missing , the, target window where that pest was exposed, we would see thousands and thousands of mealybugs, not just per vine, but sometimes a thousand millibugs per leaf. It was causing defoliation. It was causing the berries to raisin on the vine. In South Africa, populations were getting so heavy. It was killing the vines themselves.
How many people out there 20, 30 years ago were spraying so many neonics as we're saying today? We weren't doing that. now really, we were spraying for leaf hoppers as our number one pests followed by mites in case there was a flare up. It changed what we were doing in terms of pest management. In fact there's a group of us working internationally. Not just on the vine mealybug, but other mealybug species, because we've seen vine mealybug, grape mealybug, citrus mealybug, all becoming more problematic over the last decade. And we're, asking that question, why? What has gone on? And one of the thoughts we've got, not yet shown, but one idea is that we just sprayed so many of these, these newer chemicals that the mealybugs are developing resistance, The natural enemies are not, and we're seeing an escape of some of these mealybug species in now a, to them, a pesticide lessened environment.
[00:05:10] Craig Macmillan: speaking of biological control, so this is an invasive pest, came from outside the U. S. That's the kinda the classical biological control problem. the pest comes, but its natural enemies don't come with it. there are some natural enemies of vine mealybug in the United States.
[00:05:24] Kent Daane: Yes, they are, and I don't want to go too deep in the weeds on this, but this is new, very exciting to me. I did an importation program, that's a classic biocontrol program, where we go to the pests, origin, we look for natural enemies and we bring those back to the United States. Growers can't do that.
It's got to go into quarantine. We have to study those natural enemies. Sometimes for years to make sure that they're not going to do any harm.
The classic example people think about is I've got a problem with rats. And so I bring in a weasel, the weasel kills all the rats, and then starts going after my chickens.
We don't do that anymore. Classic biocontrol is now much more modern. We've got all kinds of protective barriers against making a mistake. In fact, I think that we've gone a little bit too far. I think we're overly cautious.
Bringing this back to the Vine melaybug, I imported material from Europe, from Israel, from Egypt, and from South Africa. We were finding mostly the same species in most of these different regions. The two most important species at that time were called Anagyrus pseudococci, which is The well known parasitoid that you can purchase from insectaries. The other one is Coxydoxinoides peregrinus, no common name on these insects. Both are established in California.
When I did this work, we noticed a difference between the anagyrus near species Pseudococci that we were getting in Sicily and Spain with the material that we were getting that had already been established from Israel
and what we're finding in northern Italy. Working with a taxonomist, Sergei Trapitsin he found some significant differences between these. And later on after both were imported in the United States determined that these were two species, one still Anagyrus pseudocoxi and one Anagyrus vladimiri. So sometimes you'll see insectaries selling Anagyrus vladimiri and you think, Oh, I want that.
That's different. It is different, but both are established in California. We're actually going to do a followup study. now in collaboration with this international group to find out what we've got in California. I suspect we've got both. Now, why is this exciting? Because at the time we were doing this work, we felt like the parasites were different, and we felt that these different groups that we were importing, maybe one had co evolved with the citrus mealybug, And the other with the vine mealybug. And we had already done some work with the vine mealybug, molecular work, looking at its relationship to each other around the world. and their names are, scientific names would be citrus mealybug, planococcus citri. Vine mealybug, we knew as planococcus ficus, which means, Ficus tree, fig tree. And we were showing that this group was, they had an outlier and ours was the outlier. And then working with this international group, they said, look, back in the fifties, there was a planococcus vitis. And I think what you've got, what we've got on vines, is the vine mealybug. But not in Iran and Iraq at that time.
And, and maybe in that Mediterranean region Israel, Egypt, Iran, Iraq, Turkey the Mesopotamian region, I think is what it is. Maybe there are some parasites there that we didn't have. Certainly, my colleague in Egypt and more parasites than we were finding in Europe. We just weren't able to get them all to establish in colony in quarantine. So it opens up the window that, that maybe there's something still out there. At this point in time, I say in all the countries where vine mealybug is reported as a problem, that's most of Europe Mexico, South America South Africa. We have the best of those parasites.
We just want to delve deeper into what are we seeing in Turkey? How does that match up with what we know is in Egypt? And I do have colleagues in Iran. It's just harder for me to go there.
[00:10:09] Craig Macmillan: right, of course. so this makes me think, is it possible that we have mixed populations of these mealybugs in California on the same plant, so it's different areas?
[00:10:17] Kent Daane: So that's the project we're working on with this international group. What we decided to do in a three part approach is to first find out what everyone's got.
The assumption is that in South America, In the United States, North America, we have got single invasion events. Our guess is that it arrived in the U S in Coachella and Mexico at the same time. We're pretty sure that the population they have in Peru is from California Yeah, they were bringing nursery wood in and lo and behold, they found vine mealybug. We went down to look at a nomatode problem to be honest with some UC California researchers. And we found that they had some mite problems at the same mites that we've got in North American California. So they were probably not being very cautious in what they were importing. So we're assuming that South America's got this California group which came from Israel. We know Israel and Egypt have something very similar, but it's different than most of Europe. South Africa is similar to Portugal and Spain, which makes sense with the trade routes that were going on in the 1960s. What we're guessing is that The European groups, there probably are, there's reported failures of vine mealybug mating disruption in some European areas. And we think that probably is this other mealybug that is probably in Turkey. So it's all very exciting to me, kind of delving deeper into the weeds on this. But the first part of this international group, again, a great group of people, Europe, South America our first part is what do we all have? Our second part is what we're doing a grower survey that we actually sent to the vineyard team and they spread out to some growers as well.
What are, what are growers using to control the mealybug? Because maybe with some of the, we find out what it is and maybe growers are working harder to control our vine mealybug than say that the fig millebug which appears to be what they've got in most of Europe.
Remember when I started the foreign exploration when I was in Spain growers would tell me yeah we've got the vine millebug but it really is not much of a pest. Citrus millebug on vines is more of a pest. Well they probably have that fig mealybug but
[00:13:01] Craig Macmillan: Ah,
[00:13:01] Kent Daane: You know, taxonomically, it looked to us like the vine mealybug.And I hope I'm not throwing all these things out and it's confusing.
So, second part, that is, the survey. What do you have and what are you using to control it? And if it matches up that, yeah, what we've got is the one that's more difficult, that fills in a lot of boxes. Third and fourth part are now looking at the natural controls.
What parasites are you getting coming off of this? What parasites are in your region? And how do they respond to the pheromones that we know are out there? So if they're not, if they're responding to both citrus and vine, maybe that's an indication that it's this other group. If they're not responding at all, or weakly, yeah, we've, we've got three or more distinct species. And we can't tell them apart, but maybe the parasites can.
[00:13:56] Craig Macmillan: this is kind of a practical question. hoW do you monitor parasitic wasps? They're tiny. They live in refugia. They then come out and plant their eggs in their host. that seems like a really hard thing to do.
[00:14:10] Kent Daane: That's an absolute fantastic question. So let's look at that most common parasite, Antigyrus Pseudococci slash Vladimiri. So what we found over the years is that it does a great job on mealybugs that are exposed in the fruit, on the leaves, on the cane. By the end of the season, if you're not putting on a lot of contact chemicals, you're getting greater than 40 percent parasitism. Very easy to see,
[00:14:43] Craig Macmillan: Right.
[00:14:43] Kent Daane: doesn't do very well against the mealybugs under the bark, because it's got this searching behavior where it's got to get on top of the mealybug, determine how big it is, do I want to put a an egg that's not fertilized in that, which would be a male, and they need smaller mealybugs for that. Do I want to put an egg which is fertilized? In that, that will become a female parasite that needs larger host.
[00:15:09] Craig Macmillan: the same insect, the same parasite has the ability to do either.
[00:15:13] Kent Daane: Yes.
[00:15:15] Craig Macmillan: Wow.
[00:15:15] Kent Daane: again, this is really a neat subject and I hope I don't bore the audience too much. But, a lot of these parasites that become important for mealybugs they have this little sac, so you've got your oviduct going to your ovarioles, in the female.
And right around the oviduct area, before it splits into the two ovarioles, you've got this little sac called the spermatheca. unlike humans, where the sperm goes in and Seeks out the eggs and fertilizes it. The sperm go in and the female parasite stores them in the spermatheca. And then as the eggs are mature and ready to go down, oviduct and get ready to be oviposited into the mealybug, the female decides to fertilize the egg or not fertilize it.
And if it's fertilized, it becomes a female. If it's not fertilized, it becomes a male. And that allows her to determine what the host size is, because the females are bigger than the males. And so she will walk up and down. and size that mealybug and say that this, this mealybug is a good enough size that this is worthy for me to put a fertilized egg in and that will become a female.
Or a second in store mealybug, she'll say, this really isn't that good of a mealybug host. So I'm going to put An unfertilized egg, and that will become a male. And that was, going back to this Anagyrus Vladimiri versus Pseudococci, that was the most important difference that we found in this Sicilian and Spanish group of Anagyrus, was that they would oviposit and put females in smaller hosts than the male. earlier parasite which probably evolved on the citrus mealybug.
So going back to this question because I do go off on different tangents. How do you sample for these things? So it's really easy to find a mummified mealybug on a leaf. But remember what we're doing. We're spraying now a lot of Movento and we're spraying a lot of the Neonics regardless of its Admire, Platinum, or generic derivative. They're all good materials. and maybe you're putting on an IGR like a plot, again, all good materials, Assail, all good materials. What they tend to do is work really good against the mealy bug, which is exposed on the leaves. Our systemic materials are really good at going out to the leaves. Our contact materials, our IGRs, the neonics, that are contacts kill the mealybug that's exposed. All of these materials do less of a good job with the mealybug underneath the bark.
we're not getting a true indication of what these parasites can do because we're killing the host that's the best location for them to attack. So that means to really find out what's going on, you got to strip bark oftentimes. So now you're looking at parasitism in that region of the vine that the parasite doesn't like to be. Now, if we add to this, this other good parasite, which is the coccidoxoenoides peregrinus, we really liked to bring this in because it attacks the very, very small stages of the mealybug, the first and the second instar. It's sometimes a small third, but really it's focused on the second instar.
[00:19:05] Craig Macmillan: Got it.
[00:19:06] Kent Daane: It's in California. You can find it, but it's really hard to find out what impact it's got because it will parasitize the mealybug and will cause the parasitized mealybug to die. to feel sick and to seek out some area for protection because the anagyrus if you see that mealybug parasitized on the leaf causes that mealybug to kind of glue itself down to the leaf You have to flip that thing to get it off the leaf.
A mummy is a dead mealybug which sticks to the leaf. The coccydox anoides causes the mealybug to find a place of protection because it doesn't stick it to the leaf. So it often times goes to the trunk, or goes to the stem, and eventually falls off the vine, and will pupate down into the ground.
And so to sample for that one, you have to collect them as first or second instars live, bring them back to the insectary, and rear them out to the parasite, which is just really a lot of work hard to do. so these things are far more difficult to do. Sample four, then going out and counting, you know, aphid parasites, which are just out there as little brown mummified aphids.
[00:20:29] Craig Macmillan: it sounds like this would play a role in my timing of my insecticide applications, whether it's Spirotetramat or Neonic or One of the programs that I think is common is to have spirotetramat on top and have a myothiamethoxam soil applied. Does that sound right?
[00:20:47] Kent Daane: Yeah, that sounds right. I mean, they're both good products and they're doing what they're supposed to do. they're killing the mealybug. And when the timing is right, they're getting out there before the mealybug. So as the mealybug is going out towards the leaves. You know, they're probably doing a better job than the parasite will do on its own.
Now, if you are an organic grower and you can't use those materials, then timing does become a little bit more critical because you're putting on, oftentimes, organic materials every 10 to 14 days because they've got a shorter residual. So on those you may want to, you know, work your timing around to avoid to give it a window of opportunity some of these natural enemies. There you're looking on the leaf, you're looking for mummified mealybugs. You know, are, do I have some of these good natural enemies in the field? You're looking for the mealybug destroyer, or one of the other beetles. Green lancelings are also doing a pretty good job. So you're monitoring those. And maybe you're deciding, I've got a lot of good activity maybe I should wait to put on pyganic or one of the other materials, which is broad spectrum give the other parasites a chance, a cycle, to see what their impact's going to be on that millibug population. Or maybe you're going to leave every fifth row unsprayed to let the parasites come back in and then hit that row later. So you've got a chance for those natural enemies to move the just sprayed vines.
[00:22:22] Craig Macmillan: That was going to be my next question is what is the refugee situation for these parasites? Do they come into the vineyard, do their thing and then leave? Do they come in when there is host and then they hang out in the vineyard for the rest of the season? Do we know? I'm just thinking about ways that I can preserve, conserve those parasites as much as possible so that they're there when I need them.
[00:22:45] Kent Daane: That's a great question, Craig. And let's break this apart into two different areas. Let's talk about First, the generalist predators that I just mentioned, the green lacewings, a good mealybug predator against the smaller mealybug stages. A lot of the things we do to enhance natural enemies will enhance generalist predators.
So that's where your cover crops come in. That's where your pollen and nectar come in. You'll increase generalist predators. Ladybird beetles, green lacewings, minute pyre bugs, those can all attack and kill. That same group of cover cropping that brings in the gentleness predator may have little impact on the specialized parasitoids.
Things like the anagyrus and the coccidocsinoides, what they want is the mealybugs. And not all mealybugs will do. They really want the mealybugs that are better hosts for them. So, they tend to get everything they need out of that pest population. They can host feed. They can stick their ovipositor into a mealybug, turn around and feed on some of that exudate, some of what's being bled.
The mealybug creates honeydew. That honeydew, instead of trying to plant a cover crop for honeydew, that honeydew serves as a food to increase the longevity of those parasitoids.
And as the mealybug density goes down, the parasite numbers should go down as well. Now there are different kinds of food sprays that we hope to look at that oftentimes do help increase both generalists and perhaps specialist natural enemies.
[00:24:46] Craig Macmillan: Hm.
[00:24:46] Kent Daane: The number one thing you do to to enhance beneficial insect numbers is to watch the broad spectrum insecticide sprays or to time them where you're not spraying, you know, all 100 acres at the same time, but you're leaving a refugia so they can move back in.
[00:25:08] Craig Macmillan: Interesting. So, I might be looking at something and saying, okay, I am going to have to take some action here. I'm hitting an action threshold but not pull the trigger on the whole thing. leave one area for a little bit, and then can you come back and treat that later, so that you're preserving some of these folks, and then they can come back on the other side, and find a balance between the chemical and the biological.
Mm
[00:25:31] Kent Daane: Right. A balance, a delay might just be 10 days, might be 20 days. We don't want to miss our spray window, but remember, Most of the natural enemies are winged as adults, whereas the female mealybug is never winged.
Fairly slow, fairly thestle. So that allows for those beneficials to come back in. And if you're a large grower this just happens over over the course because you can't spray 100 acres in a day.
[00:26:07] Craig Macmillan: Right. Right. Fascinating. Are growers starting to adopt, in your experience with the folks that you work with, are growers starting to adopt these kinds of timings and techniques and methods?
[00:26:19] Kent Daane: I think growers are constantly adopting, improving, changing one of the common misconceptions when I talk to students or people who just don't don't know how to farm or farmers is that farmers really don't want to spray.
Spraying costs money. it is an added expenditure, added time, added worry. So they'd much rather, you know, go back 50 years when we didn't have all these invasive insects from Vine mealybug to Virginia Creeper growers are always seeking out how to improve the insecticide materials they've got, how to reduce the insecticide applications they have to make. And that does include natural enemies, mating disruption. What it comes down to is just costs. So oftentimes there's a trade off.
If you're going to use mating disruption, you may not be doing three applications of an insecticide for vine mealybug. Maybe it's one insecticide plus vine mealybug mating disruption. If you're organic and you're releasing beneficial insects and spraying every other week. Maybe you don't have the cost for mating disruption. So these are all decisions that individual growers have to make. Obviously we've got some growers in some regions can spend 300 per acre for mealybug control. Other growers simply cannot do that because of the value of, their product at the very end.
[00:28:03] Craig Macmillan: Right.
This is kind of a natural lead in to something I wanted to touch on, and that is the Virginia Creeper leafhopper that's found on the North Coast. That also an invasive, correct? Came in from outside.
[00:28:15] Kent Daane: It is invasive to some extent. It is not invasive like the vine mealybug is from. The Mediterranean region Virginia creeper most likely is, is North American. But yes, it was never really a California leafhopper pest. It was, no England, Canada. Pest that then went into Washington, then went into Oregon, that then came into California. interestingly, the, leafhopper that I worked on for so many years the variegated grape leafhopper probably North American, probably had a different avenue, probably came up from the south, from Mexico, Texas, to Arizona, to California. So Some of our invasives are close relatives.
[00:29:07] Craig Macmillan: Interesting. what's the difference in damage that's caused by the Virginia creep leaf hopper and the the variegated leaf hopper.
[00:29:17] Kent Daane: So they're, they're very similar.
I think that the grape leafhopper is the one we've been dealing with for the longest time and has been relatively mild compared to the other two.
The variegated grape leafhopper When it first came into the San Joaquin Valley, it could defoliate vines. It had three to four generations per year.
[00:29:42] Craig Macmillan: Oh, wow.
[00:29:43] Kent Daane: It seemed to be much more damaging than the grape leafhopper.
Virginia creeper leafhopper, now in northern California, making its way south. So it's gotten to the middle of the state. It's in Napa, Sonoma, Sacramento. I have not seen it. Heard it reported in the Fresno area. Oh, it has been reported in Fresno.
But I'm not saying it causes much damage here. We really don't get many leaf hopper reports for damage here, except for organic growers. And that's because all the sprays for vine mealybug.
Most of those vine mealybug sprays are very good against the leaf hoppers. Where I have seen it as a pest. It's been mostly in wine grapes. Mostly in the cooler regions of the state. Mostly controlled by conventional insecticides. There are programs organic materials registered for Virginia creeper that I think have done a fairly good job. But it, it does get out of hand. And I think for all these leaf hoppers with organic materials, what happens is that The organic products tend to not work well , against the leaf operant in the egg stage or the leaf operant in the adult stage.
So timing is very important. You want to get those materials on. when egg hatch is nearly complete and when you've got mostly first and second instars out there. That's because most of our organic products tend to impact these pests by either being a desiccant like the soaps that dry it out or a suffocant like the oils that clog the spiracles. And so the the, adults just fly away from that tractor rig as it's coming down.
The eggs are protected inside the leaf itself, in their little clusters for the Virginia Creeper. And the larger insects can, they're just more mobile. So it's hard to kill them. So timing becomes relatively critical with these insects. I've not worked directly with Virginia creeper other than hosting Houston Wilson did his graduate work in my lab and really focused on, on the parasites of this insect.
Lucia Varela, now retired, did focus on looking at the different insecticides and she's got a nice summary article which is on Monica Cooper's website. It talks about the different insecticides, U C cooperative extension Napa County.
And she's got a website that goes into materials for organic growers for Virginia creeper leaf hopper. I think that's where I saw. that information posted. And what Houston did was he just looked at and tried to improve the Enneagrus. So we get those two confused. The Lilybug parasite is Anagyrus. The Leafhopper parasite is Enneagrus.
The two names sound pretty similar, but one is an inserted family and one is a Mimerit. Or a fairy fly, fairy winged fly. They're some of the smallest insects known. So,
[00:33:03] Craig Macmillan: Wow.
So, we are continuing to look at these new parasites, how they're performing, we're learning a lot more about them, and we're learning a lot more about timing of different kinds of sprays around their life cycle.
[00:33:17] Kent Daane: Yeah, what Houston was trying to do was to understand why parasitism against the Virginia creeper leafhopper was against all the leafhoppers. Why parasitism was relatively low. So I was working with Danny Gonzales and Sergei Tripitsin,
And just mentioning to the taxonomist, Sergei, that it seemed like there were differences amongst these Enneagris samples that we were releasing.
And I had happened to save all of the material that had died. So I sent that to Sergei, and Sergei looked at these things closely and then said, look, we've got a complex of parasites. And he named Enneagris erythronureae. After the species that was most commonly attacking variegated grape leafhopper, which is Erythronere variabilis. There was another one, and he called a Negris tryptocova, which was named after his wife's father's family and he said that was the better looking one of the group. And there was one that just didn't do that much. And he named that after me, a Negris Dana. And so that one we thought was the one attacking the western grape leaf hopper most commonly. And it was being found more commonly in the riparian zone. So that's 20 years ago, fast forward to our new invasive leaf hopper, the Virginia creeper leaf hopper, which is again coming down from Canada to Washington to Oregon to California. Well, it ends up that the Enneagris deni is very important attacking that leaf hopper.
So Houston was working out the relationship of these three parasites against these three leaf hoppers and trying to understand if he could manipulate their numbers to improve biocontrol. He looked at hedgerows, he looked at augmentative releases or inoculative releases, and we're still curious to see if that can't be improved even.
[00:35:30] Craig Macmillan: That's fantastic. Another topic that I wanted to touch on, because it's a really cool idea, and I think we'll have applications across a lot of things eventually, and that is area wide pest management strategies. And I know that you've done a lot of work in this area from the beginning, really, of kind of the concept.
What is an area wide pest management strategy? Management program. What does it look like? What can it what is its goal? How does it operate? What kind of success we've seen so far?
[00:35:59] Kent Daane: Yeah, that's a fantastic question. It's a topic I'm really excited about and let's think about it when we think about the European grapevine model. that was another invasive insect,
It was found in California, it was found in Chile around the same time. So you've got this invasive insect, and the state of California deemed this important enough to have an eradication program.
[00:36:22] Craig Macmillan: Oh and just real quick. What kind of damage does grapevine moth do?
[00:36:26] Kent Daane: So the European Greenvine Moth it'll feed on the vine, but it gets in the fruit clusters. think of the omnivorous leaf roller One of those, one of our tortricid pests that can really cause damage to the grape a number of generations per year, a lot of different possibilities where it might come from in terms of a host plant material.
So it can be very problematic. It would require a spray every single year, an additional spray for a tortricid pest, if it were to establish.
[00:37:00] Craig Macmillan: one the big issue here is that it attacks the berries directly
[00:37:03] Kent Daane: absolutely.
[00:37:04] Craig Macmillan: Okay. So that's a, that's a serious problem.
[00:37:07] Kent Daane: No, no, the, it, it causes mold and rot and everything else once it gets in there. So, you know, two or three doesn't seem like a lot. You just think, well, berry can go to crush, but that berry will get all kinds of bunch rot.
not a good fruit. So when you think about the eradication program, where there was monitoring everywhere in the state. When you think about the eradication program, where when they found this pest through pheromone traps, and then they did a ground search to find out where it was. And then there was a coordinated investigation. Effort to spray the right materials, to use mating disruption, to go after it in all of the adjoining areas. those eradication programs are very intense. Area wide control programs.
So, let's think about Vine mealybug, which is now in most vineyards. We're still approaching this on an individual grower basis.
We might have one grower using mating disruption, because they're going to go organic, and a next door neighbor doing nothing. There's going to be constant movement of that pest into that grower's. field We might have two growers, one using Movento every other year, and another using Platinum every other year. Those males are going back and forth between those vineyards, sharing whatever genetic resistance that they're developing.
And so really, if those growers are switching, one's using Movento, one's using Platinum that insect is moving between those vineyards all the time. And it's not a resistance management program,
or you might have a small five acre grower deciding to put out mating disruption. Mating disruption works better blanketing the whole area. So an area wide program, and then you bring into it the idea of roguing leaf roll diseased vines.
there are two things I just mentioned in this last 30 seconds that are so important for area wide management of mealybug and leaf roll that are the killers to those programs.
The first is mating disruption still costs more money than a pesticide application. It's a fantastic tool. It is a tool that works better the lower and lower the mealybug density gets.
So you use insecticides to really drop the mealybug population down, but there gets to be a point where the mealybugs are now on the bark. There are little populations here and there, and we know the insecticides are never 100 percent. Mating disruption works better. The lower the milli buck density is.
[00:40:05] Craig Macmillan: Got it.
[00:40:06] Kent Daane: But there's a cost to it. So we start with insecticides. The next part is the rowing of the infected vines.
That's very important on an area wide basis because if you're planting, you've had, vineyard is old, it's not productive, it's had leaf roll. You pull it out, but it's right next to a block that's got 80 percent infected vines. You're always going to have new infections showing up over and over and over again.
Unless that grower next to you is just doing this bang up job of applying insecticides all the time to keep mealybugs from going into your vineyard. you can make area wide control work for the pathogen. and the pest.
But in the best world, let's say you're in control of a thousand acres, pull out every vineyard that's infected and replant and then pull out every new infection in it. And people just can't afford this.
[00:41:06] Craig Macmillan: Right.
[00:41:07] Kent Daane: if you're managing 200, 300 acres and Your vineyard with leaf roll that's at 30 percent is still profitable. it's hard to pull out those 30%.
It's just hard to do. I get it. But something that I wish we could get, you know, government subsidy for to, to have them help us come in, pull out the infected vines, start clean again. But it does work. It's worked in South Africa. It's worked in New Zealand. It's worked in Napa. It just comes at a cost that may be prohibitive in some regions, in some areas. So the best we can do is to manage mealybug and the disease incidence in an area wide manner.
[00:41:52] Craig Macmillan: if I remember correctly, I mean, the work has been done now that, demonstrates roguing is your best strategy overall long term, but it's expensive short term. and that is the issue. That's the tricky bit.
[00:42:06] Kent Daane: There are two tricky bits to it. The first tricky bit is the expense you just talked about. The second tricky bit is that in most of the regions where we know it's worked They have not been dealing, perhaps, with our vine mealybug. They've been dealing with the grape mealybug, long tail mealybug, obscure mealybug. we've got I think the worst mealybug. And maybe that mealybug is just better at surviving on root remnants.
You know, you hear all the time from growers, I r I've been removing 10 percent of my vineyard every single year for five years. And when I looked at The south African data, they removed 20%. Second year, 5%. Third year, 3%. Fourth year, 1%. And after that, it was always 1%.
[00:42:54] Craig Macmillan: last piece of this puzzle in my mind is you have to get your neighbors to cooperate. That's the area wide bit. You have to get people to get on the same page in terms of what they're doing. And it sounds to me like they don't necessarily have to be doing exactly the same thing. They just have to be sensitive to what somebody else wants to do.
Does that sound right?
[00:43:15] Kent Daane: There are areas where it has worked well. It can work in the Central Coast. It can work in Lodi. We may not see, you know, eradication of diseased vines. We may not see a reduction of vine mealybug to a point where we can treat every other year. We might be treating every single year. for this, but we can improve what we're doing through communication right now.
In the central Valley, we're working with a great group of growers where we're just mapping out the vine mealybug and we're sharing with the growers where the melaybug populations are. It's their decision. What? What to use, what to do for control. It's their decision. Can they rogue or not rogue?
But what we're trying to do is to help foster communication amongst the different growers that are neighbors, because we're a third party, which I think helps a little bit. it would be fantastic if we could have someone hired as a scout or PCA, where we work with. PCAs in the region and everyone shares data. We're trying a new computer program this year, which we at the end of the season, we'll launch with our collaborating growers where they can log on in real time. and see what the trap counts are as we count those trap counts. And that will help them make a decision, we hope, on what to do in terms of control measures. But again, the best thing might be that we're opening up communication, just as the Vineyard team is doing through podcasts, through field days, through the website.
[00:44:55] Craig Macmillan: Well, let's hope. And I, and there's a number of other organizations too. the, the group in Lodi has done a fantastic job from what I understand. Fostering communication and sharing information. like you said, I think that's probably one of our, our, our best hopes. Is working collaboratively as an industry and getting communication between the experts like PCAs and the extension community. .
[00:45:15] Kent Daane: And of course, anyone can always reach out to me with questions as well.
[00:45:18] Craig Macmillan: Fantastic. And we'll put your information in the show notes. I want to thank you for being on the podcast. fantastic. Very helpful and very, very exciting. I think I was feeling a little more dismal about this whole topic coming into this interview than I am now. I think there's maybe more potential than I was kind of giving credit.
I, you know, I come from a time back in the 90s when Vine Mealybugs showed up in the Central Coast. And it was a lot of gnashing of teeth and pulling of hair, and we did not know what to do, and the damage was insane. I mean, I saw stuff that was just blood curdling, and I think we've come a long way.
We've come a long way, and that's from the efforts of folks like you, so I really appreciate it. I want to thank our guest, Kent Daane. He is a Cooperative Extension Specialist with the University of California, Berkeley. he works primarily out of the Kearney Ag Research Extension Center. And, thanks so much for being on the podcast.
This is great.
[00:46:10] Kent Daane: Thank you very much. Enjoy the harvest time coming up.

[00:02:14] Craig Macmillan: Our guest today is Allison Jordan. She is executive director of a California sustainable wine growing alliance. And today we're going to be talking about the green medal awards. Hey allison, thanks for being on the podcast.
[00:02:30] Allison Jordan: Great to be with you. thanks so much for having me.
[00:02:32] Craig Macmillan: So let's start with some basics. What is the California sustainable wine growing alliance? And in particular, what is it? What are its goals? And what's it doing to achieve those goals?
[00:02:42] Allison Jordan: Well, the California Sustainable Wine Growing Alliance is a partnership that was created by Wine Institute and the California Association of Wine Grape Growers back in 2003 as a nonprofit organization that's all about promoting sustainability from grapes to glass. some of the ways that we do that, especially the whole idea of encouraging adoption of sustainable wine growing practices is also around communicating about it so we can really tell the story about California's leadership in sustainability.
[00:03:14] And we do that through education, through outreach, through certification, and also through partnerships. So for instance, the vineyard team is a great partner of ours and us. Fantastic work. Not only in the central coast, but also throughout the state.
[00:03:31] Craig Macmillan: Thank you. I know that we've really enjoyed and benefited from our work with you. And also around the Green Medal Awards. what exactly are the Green Medal Awards? how did that come about? What was the purpose of creating the awards?
[00:03:45] Allison Jordan: So during Down to Earth Month each April, which is a chance to really highlight California wine community sustainability leadership we also celebrate the California Green Medal. The full name of the awards is the California Green Medal Sustainable Wine Growing Leadership Awards. And it's our way of recognizing industry leaders.
[00:04:06] So those who wineries and vineyards that are really using advanced sustainability practices. They're innovating and they're sharing that information with their peers. It really was a way for all of the different California sustainability programs to come together.
[00:04:21] We're all really about elevating sustainability. And so we came together with not only the Sustainable Wine Growing Alliance, which of course is this partnership with CAWG and with Wine Institute, but also with the Vineyard Team and Lodi Wine Grape Commission. Napa Valley Vintners and Napa Green, and also the Sonoma County Wine Growers, so that we could all be part of celebrating and shining a spotlight on these leaders.
[00:04:46] Craig Macmillan: I think that's one of the really great things about this. And my understanding is that you actually have representatives from different organizations that are part of the review committee for the applications and also part of the cross promotion. Is that right?
[00:04:57] Allison Jordan: That's right. Yeah, so all of those organizations are involved and participate in the judging panel. We also have experts from universities, the wine education field some representatives from retailers and, and some somellier have. Participated in the past. So we try to have that really well rounded group that can be reviewing the applications from wineries and vineyards around the state.
[00:05:20] Craig Macmillan: that's really fantastic that you have expertise from around different fields and different areas. I think that gives it a lot of weight and a lot of legitimacy. So let's get to the purpose of all this. So who are the 2024 green medal award winners and what are some of the sustainable practices that they employed that garnered them this recognition?
[00:05:39] Allison Jordan: Sure. I'll just run down the list. So every year we give four green medals and they are in the categories of leader. So sort of the overall. Embracing sustainability also in the areas of environment, community, and business. And this again helps us really share in lots of different ways what sustainability is all about.
[00:05:58] So for the Leader Award this year, which again is all around that excelling in all three areas of sustainability, being environmentally sound, socially equitable, economically viable. It goes to the Lang Twins family winery and vineyards. They're based in San Joaquin County, just north of Lodi, and have been very involved in sustainability, both in the Lodi region, but statewide for, for many, many years.
[00:06:22] Really, since the inception of our programs. And if you think back further, because it's a generational business they've been embracing sustainability since the early seventies. just some of the examples of things that they've done. They've done a lot around habitat restoration projects. I've actually had the chance to just go in and do a walking tour just a couple of weeks ago, and it's just impressive how they've really repaired that riparian habitat, working with local youth and providing hands on environmental stewardship education for them.
[00:06:53] But they also started off as a family of growers and built a state of the art winery. Just within the last decade or so and they really included a lot of energy efficient design and solar power technology. So just a really great example. thinking back some of the other past winners in the leader category are Treasury Americas, Wente Family Estates, O'Neill, Vintners and Distillers, and J. Lohr Vineyards and Wines. So some really great examples of leaders in our industry.
[00:07:25] The next category would be community. of course, this is all around what vineyards or wineries do to enhance relationships, not only with their employees, but also with the broader community and with their neighbors.
[00:07:39] And this year it goes to Cooper Garrod vineyards at Garrod farms, which is a beautiful vineyard and winery, and also a horse farm in the Santa Cruz mountains. really I've known. Doris and Bill for years, Bill was a former chair of the California Sustainable Wine Growing Alliance, and they just give their whole heart to their community.
[00:08:00] They have done things like pioneering the FireWise Community Initiative. They actively participate in benefits for their schools, for mental health. They participate in the Chambers of Commerce and the industry groups. And also to foundations. they really invite the community in so they can use their farm's hiking trails and participate in winemaker walks and all kinds of really fun ways to learn about sustainability.
[00:08:26] And just thinking back again on some of the past winners in this category, we had Cake Bread Cellars, McManus Family Vineyards, and Smith Family Wines. And there are two more. Do you want me to take a breath or do you want me to keep going?
[00:08:40] Craig Macmillan: no. Keep going. This is great. Yeah.
[00:08:42] Allison Jordan: All right. So the third category is the environment. Something that I think people think of a lot when they think about sustainability.
[00:08:50] there are those vineyards and wineries that are really maximizing environmental benefits. And this year it goes to Gloria Ferrer in the Sonoma region of Carneros. they use regenerative organic farming practice is something we're hearing a lot about. Regenerative is, is the new buzzword in the world of sustainability.
[00:09:06] they're introducing biodiverse cover crops implementing high intensity sheep grazing. They create biochar and really thinking a lot about how do you build healthy soils and minimize your overall environmental impact. They've also established wildlife habitat with things like hedgerows and pollinator friendly areas and nesting sites. So they're really attracting that wildlife into their property and fostering biodiversity.
[00:09:33] And I can think of some really great past winners too. Tobless Creek, Trefethen, Scheid Family Wines, and also Halter Ranch Vineyards.
[00:09:41] So again, some stellar examples of environmental stewardship.
[00:09:45] Craig Macmillan: Yeah. Very heady.
[00:09:46] Allison Jordan: yeah, exactly, exactly. And we have the Business Award as the final category. And this is given to the Vineyard or winery that best demonstrates smart business practices. So things like looking for those efficiencies and related cost savings and innovation.
[00:10:05] And this year's winner for that category is Vino Farms. They are a vineyard management company based in Lodi, but they farm all over the state and they've used all kinds of different advanced technology, for instance, for water use efficiency, they've used Tule towers and soil moisture probes and ceres imagery.
[00:10:27] And the idea is to really understand water needs to prevent overwatering and to make sure they have uniform water distribution. And, of course, this can lead to substantial cost savings in addition to saving water. They've also done things like releasing beneficial insects via drones. To reduce the need for pesticide applications.
[00:10:46] And of course, again, the associated costs with that. And then they've also done a lot to embrace renewable energy. So they transitioned all of their trucks and tractors to biofuel since 2010. So going way back They use solar panels in their vineyards to power ranch shops and also water pumps.
[00:11:06] And some of the other examples of this category winners are Niner Wine Estates, Jackson Family Wines and Monterey Pacific. So some really good examples of both vineyards and wineries that have done some amazing work that are really driving that innovation.
[00:11:23] Craig Macmillan: Did you say this is the 10th year? Is that right?
[00:11:25] Allison Jordan: It's right. It's the 10th year. So we've now had close to 40 recipients of the Green Medals. We've had a couple of that have won multiple years Tablas Creek being one of them, Trinchero Family Winery being one. So when you look at the full picture, it's probably around 36 different recipients of the award.
[00:11:43] And if you visit greenmedal. org, you can see all of the current and past winners and some video highlights of the winners. And just, it's a great way to learn really delve into what does sustainable wine growing mean on the ground.
[00:11:56] Craig Macmillan: Yeah, it's, it's another way of having that kind of farmer to farmer, winery to winery contact to see what people are doing and, and how they've made it work and kind of encourages people to try things for themselves.
[00:12:09] Allison Jordan: Exactly. Get some good ideas of things that you might want to talk to them about. And I think that's another key thing about wine growing. Virtually all of our green metal recipients, I feel like are leaders in that they're willing to share that information and participate in field days and workshops and all of the things that all of our organizations do to advance sustainability.
[00:12:28] And when you look at it, it's amazing. We're the fourth largest wine producing region in the world. And today we have 85 percent of California wine being made in a certified sustainable winery and 67 percent of the acreage is certified to one of the California programs. So it's really exciting to see that level of adoption.
[00:12:47] Craig Macmillan: Yeah, we've come a long way.
[00:12:49] Allison Jordan: We really have.
[00:12:50] Craig Macmillan: We really have. Thanks to the efforts of folks like you.
[00:12:53] Allison Jordan: It's been a pleasure to be working in this field for now over 20 years, which is hard to believe.
[00:12:57] Craig Macmillan: I know, I know. Is there one thing that you would tell growers regarding this topic in terms of either applying for awards or how to use what you can find from award winners?
[00:13:10] Allison Jordan: Yeah. So I feel like the awards is one example of how you really have to think of all of the costs and benefits of sustainable wine growing. And as you explore specific practices to make sure they make sense for your operation. One of the things that I think comes to those vineyards and wineries that are adopting sustainable wine growing is the ability to share their story and the positive public relations around it.
[00:13:35] And we can help amplify that through things like the Green Metal Awards. The green metal.org website has lots of great information about, again, the practices being used by the recipients. But also you can learn how to apply if you're a vintner or grower for the 2025 awards the applications will most likely open up around November.
[00:13:55] So keep an eye out then and they tend to be due in January. So We will be getting the word out in lots of different ways through the vineyard team and all of our partners and through the California Sustainable Wine Growing Alliance. But you can also just periodically check out greenmetal. org to see if there's any new information about it.
[00:14:14] Craig Macmillan: So we've got greenmiddle. org is a great resource. Where else can people find out more about you and your organization?
[00:14:20] Allison Jordan: Our organizational website is sustainablewinegrowing. org. We also have one for, basically for more our, our Interested consumers and retailers and other stakeholders. That's all around certification. And that's California sustainable wine.com. And then the last one I'll mention is, is again, just showing the breadth and depth of all of the different initiatives across the state.
[00:14:42] So in honor of 30 years of all of the different sustainable initiatives in the state, we put together a website called californiasustainablewinegrowing. org and it has a retrospective of some of the really key milestones. That all of our respective programs have done. So if you're looking for some of that history of how this idea and this approach has evolved in California, that's a really great place to look.
[00:15:09] Craig Macmillan: Cool. Well thanks so much for being on the podcast. This is really great. And I'm really happy that we can support some of these leaders and get some of these messages out there. I think it's really important and it's been the mission of all of these organizations. And so to be able to come together for something like this is really great.
[00:15:23] Allison Jordan: Yes. It's one of my favorite things of the year. So looking forward to celebrating the winners.
[00:15:28] Craig Macmillan: our guest today has been Allison Jordan. She's executive director of the California sustainable wine growing alliance, and we've been talking about the green metal awards here today. Please, by all means, check out the resources we've talked about and think about applying. So I worked for Niner Wine Esates, so we won the business category.
[00:15:45] And what we found as we went about it was, it was a great process internally, to list and think about all the things we've been doing. And what we realized was We were doing a lot of things in a variety of areas and you don't see that you're always focused on whatever the current project is, right?
[00:16:07] You're always focused on fixing whatever. And when we stopped and actually kind of meditated on it, it was like, wow, you know, there's a lot that we're doing and a lot that's going on. And then it also helped us identify areas where we thought, Hey, you know, maybe we haven't paid attention to this.
[00:16:17] Like maybe we should. And I just think that process, regardless of whether you're a winner or not is really valuable. It's a good exercise for people.
[00:16:25] Allison Jordan: Yeah, that's a great, great insight. And I do feel like, you know, certification is a great way to tell, to tell a story. your story, but to add credibility to what you're doing, but you still need those examples. And so taking the time to compile those and to really show what you're doing, what you're exceptional at I think is a really great exercise.
[00:16:44] So fantastic point, Craig.
[00:16:46] Craig Macmillan: All right. Thanks, Allison.

Transcript[00:02:07] Craig Macmillan: Our guest today is Philippe Roshausen. He is Professor of Cooperative Extension at University of California, Riverside. And today we're going to be talking about the soil microbiome. Thanks for being on the podcast, Philippe.
[00:02:19] Philippe Rolshausen: Thank you for having me.
[00:02:20] Craig Macmillan: Well, when we do these topics, like to start from the very basics. And then we can go very deep from there. What is your definition of the soil microbiome?
[00:02:31] Philippe Rolshausen: Well, a microbiome is the collection of microbes. The soil microbiome is the collection of microbes associated with the soil. I have to say we work on the soil microbiome, but we also work on the phytobiome, which is the collection of organisms. associated with the, the, vine, and that can be fungi, bacteria, viruses, even insects. So we are more interested in fungi and bacteria in my lab. And especially those that live inside the vine and how it's connected to the roots and the soil.
[00:03:12] Craig Macmillan: Yeah, I'm very interested in that. Just for our listeners, other aspects of the soil microbiome could include things like microarthropods,
uh, nematodes, etc. It's a very complex Complicated
ecosystem.
[00:03:26] Philippe Rolshausen: I and I only focus on one part of it.
[00:03:29] Craig Macmillan: The work that I've done with soil microbiome in a very primitive way. We just focused on total bacteria, total biomass, things like that.
You just mentioned this and this is a good jumping off point actually. Because plants are an active part of this ecosystem, you will find different soil microbiomes around different crops. What is the soil microbial community like around grapevines in particular?
[00:03:50] Philippe Rolshausen: Well compared to, to what is the question. Let's give you an example. I work on citrus and grapes in the same soil environment, you would see differences between a grapevine and the citrus plant just because of the property of the host. Within grapevine, you know. Depending on the variety or the rootstocks, I should say then you would also have different microbial communities associated with the rootstock.
And this is like a plant effect because plant recruits their microbes. So, so you have sort of a template of microbial or a core microbiome, which is you would find across a different rootstock or varieties of grapes or even plants. But then. Some are very variety specific or host specific, and so you would tend to see some varietal specificity and specific microbe associated with some of those rootstock operants.
[00:04:47] Craig Macmillan: That's news to me. That's fascinating.
there is some commonality, but you will find some differences just based on things like rootstock?
[00:04:56] Philippe Rolshausen: Yes.
[00:04:57] Craig Macmillan: Oh, that is interesting. We may come back to that. one of the things about your work that I was really intrigued by, which I was unaware of, is the different microorganisms that one might find inside the grapevine, and what roles they play in the functioning of the plant. I mean, I think most of familiar with Our gut microflora. Right, where we know that we have organisms inside us. We have organisms on our skin and all that. I didn't realize that was true for plants as well. Tell me more about that.
[00:05:26] Philippe Rolshausen: You can make the parallel between the roots and the gut, actually.
Because they have similar functions. Especially with respect to nutrient assimilation Defense against disease, for instance. Now, the gut is inside, the root is outside. Someone made the comment that the plant where there are guts on the outside, just because of that parallel that between the rhizosphere and the gut.
there is a connection between what's going on inside the plant and what's going on outside the plant. We are interested to understand what the organisms that live inside the plant. Where they're coming from. in terms of diversity the endosphere, which is the the region of the, the organism living inside the plant, the endosphere is not very diverse.
There's only a few of thousand fold less microbe capable of living inside the plant just because it's a more. Stringent environment I work on the xylem a lot and, you know, there's a negative pressure for instance, there are, there's not a lot of food available, for instance.
And so microbes have to adapt to those environments, right? And it's not every microbe is capable of doing that. there's only A certain type of microbe that can live inside them. we're interested in those because we work specifically on vascular disease of grapevines, so fungi, bacteria especially.
And we try to understand how those pathogens interact with the plant, but also really understand those pathogen within the, context of the microbial community and how those pathogen interact with the microbes living inside the plants. to go back to your question, it's like, where are those pathogen coming from?
How did they get there? How do they interact with the plant and how do they interact with the microbes? within those interaction, what would be the, the disease outcome in certain type of interaction.
[00:07:35] Craig Macmillan: So what we're talking about is we have these pathogenic organisms Which could be in the form of like grapevine trunk disease Things like that or Peirce's disease. In the case of bacteria and what you're getting at is it that there's other types and populations of microbes that may be antagonistic to the pathogen?
[00:07:56] Philippe Rolshausen: Yes. So that was our hypothesis. Traditionally, you know, microbiologists were looking for biological control agent against diseases and they were culturing those.
That was the traditional approach. So you take a plant tissue, You put it in the culture media and you see what's growing and then you test if those organism are able to inhibit the growth of your pathogen. That would be the traditional way of doing it. Now, with the metagenomics , the development of those technology, we're able to kind of look, at the entire community of those organisms living inside the plant and using those tools, we could actually select those that have some.
That might be antagonistic to certain pathogens. the beauty of this is that you can actually look at the entire community. When you look at a traditional microbial approach, you kind of zoom in on, to those that can grow in culture and those that can grow fast in culture and sort of overpower the other ones.
when you use those molecular approaches, you look at the entire community and you can And sort of a broader view of really what's going on and who does what. and so that's the approach that we've been doing to try to identify biological control agents or beneficial organism to plants and to grapes in particular.
what we do is we select plants with different phenotypes. So we will select. Plants that, you know, that range from very healthy to poor health. And we're able to build those sort of correlations with organisms that associate specifically with healthy plants and those that associate with sick plants.
and from that, once we have identified the organism, we can go back and try to culture it and to reintroduce him in the system to prove that Actually, they are beneficial in some capacity.
[00:09:52] Craig Macmillan: does this mean that I could have plant material, and one of those vines would be healthy and one would be weak and showing disease, but they both would have the pathogen, it's just that the other one has the microbial community to help fight it.
[00:10:07] Philippe Rolshausen: That's right.
[00:10:08] Craig Macmillan: Wow.
[00:10:09] Philippe Rolshausen: there's a environmental factor that comes into play as well. because abiotic stresses also so like, you know, drought or heat play a factor into the plant, weaken the plant in some capacity and will change the disease outcome and the interaction between the pathogen and the microbe.
There are more layers than, you know, the simple pathogen, microbe. plant interaction There's also the environment in which those components are part of that really plays a big factor.
[00:10:43] Craig Macmillan: So, are you finding or pursuing how those abiotic factors can be manipulated?
[00:10:50] Philippe Rolshausen: A little bit. I'm really interested in those aspects of, especially in the eras of climate change.
plants are going to be subjected to a lot more stress than they used to be. I think we need to understand how this is going to affect the, the microbiome at large and because I'm a pathologist, how this is going to affect disease outcome. we are starting to only scratch the surface of that.
I think a lot of people are as well. It's a lot more complicated when you work with. Woody perennial than when you work with an annual plant, because you have the approaches and the logistics are more challenging, I would say. drought is the number one just because it's been on the radar of every grower in California, but so we, you know, we are interested to see how those factors really affect the Have an effect on disease.
Yes.
[00:11:44] Craig Macmillan: Are you doing that in the laboratory?
[00:11:46] Philippe Rolshausen: Well, yes. You have to sort of work in more controlled conditions and sort of dissect it one stress at a time. so it is in more greenhouse conditions or gross chamber conditions where you can, semi controlled environment where you can really control heat or, you know, water or, and see how that affects the microbiome.
[00:12:07] Craig Macmillan: I think this is fascinating. can you tell me more about what that actually looks like, like how do you set it up? How are you controlling it? What kind of ranges are you using? I love the details.
[00:12:17] Philippe Rolshausen: So we've done experiments mostly with irrigation so far. And we are only starting to tie irrigation to microbiome, but we have done the.
How irrigation affects severity of disease and impact on the plant. this is pretty straightforward, you have plants that are fully irrigated that are not on the deficit irrigation, and then you calculate what a deficit irrigation like a 25 percent deficit irrigation look like, a 50 percent deficit irrigation look like, measuring, you know, how much water.
How much irrigation you put in on your plants, you inoculate your tree or vine with a pathogen, and you let it incubate for, you know, weeks, because you know, those are slow pathosystems, they take time, and you see how that affects for trunk disease in particular lesion of the wood necrotic lesion, for instance.
And then we look at factors on the plant. We measure biomass, for instance, of the roots, the shoots. We look at gas exchange, photosynthesis, and so on and so forth. going down to the microbiome, you know, we would be sampling the tissue, extracting the DNA, and then sequencing, you know, all the microbial community, bacterial and fungal, to see how those communities have changed over time in a well watered versus a deficit irrigated plants.
[00:13:49] Craig Macmillan: And is that quantitative analysis, or is it simply the complexity of the diversity of the microbiome
[00:13:56] Philippe Rolshausen: it's semi quantitative so let's say, you know, like you're looking at a presence of a specific taxa.
It's a relative abundance of the taxa in comparison to the others. So when you see an increase of the taxa. in your community, it's either because it does increase or because the other taxa within that community decreased. So it increases in, in relation to that. So it's not really an absolute measure of abundance.
It is a relative measure of abundance, but you could still use it and make some correlation with that.
[00:14:34] Craig Macmillan: Can you explain, metagenomics?
[00:14:37] Philippe Rolshausen: That's not my field. To be honest with you, but the principle is that you're using primers that are universal primers and that allow you to, so there are.
Meaning that you can sequence conserved region. So those primers are aligned with conserved region across several taxonomic groups. Okay, so fungi or bacteria. And then you sequence a length of nucleotide. In our case, it's about 200, 250 nucleotides in length. In between, and this is valuable between those two.
Primers, that region is valuable. And so you could start making you can do a micro real fingerprinting and identify which types are, are present, you know, but it's the community of organism. So it's like all the fungal communities or all the bacterial communities. So some primers are better than others for special taxonomy group.
So for instance. I work with Dario Cantu at UC Davis, CBT Controlled Neurology. Davis uses field of knowledge, and so he developed primers for group causing grapevine trunk diseases. And so it's mostly what's called the Ascomycota phyla. his primers are mostly focusing on this group of, fungi, but it doesn't give any information on The basidiomycota, which is another group, or the glomerulomycota, which is the mycorrhizae fungi.
if you wanted to get information about this group, you would need to get a different set of primers, right? so it's really up to primer that you're using that gets you the right information. and also the database that you're using that gives you the right information because sometimes the database are not curated or they're not accurate, and those are getting better as we're getting more and more knowledge about the taxonomy and, and the biology of those organisms.
we're able to make more accurate prediction because we're gaining more knowledge about those organisms. So for instance, there's a lot more information about bacteria than, They are about fungi just because there are not a lot of reference genome for fungi compared to bacteria. so it's a lot more difficult to predict. Sometimes for fungi than it is for bacteria.
[00:17:01] Craig Macmillan: But it sounds like that would be coming down the road.
[00:17:04] Philippe Rolshausen: Oh yeah, yeah, it's a matter of time. I mean, really, you know, this technology is going so fast, so quickly that, in five years from now, I can't even predict what it's going to look like,
[00:17:15] Craig Macmillan: This thought just occurred. your work is obviously, I don't want to say infancy, but it's, it's pretty early work. You know, we're, we're working with tools that are still in development, basically. at this point, would you say that there are certain conditions or practices or manipulations that a grower could use to promote the most beneficial endo, um, microbiome in their plants?
[00:17:40] Philippe Rolshausen: In principle, yes, and I believe that this is true. We just don't have the knowledge yet to make recommendations that are solid. There we go. So, when you apply something to your soil, you know, if you're a grower and you apply fertilizers, or this is going to, or even if you if you till your soil or it will have some impact on the soil microbiology.
That we know. How that reflects to what's going on inside the plant, we are, we are not there yet. We, we don't have that knowledge yet just because like I've said before, only a few of those organisms move inside the plant. There's always a a gap between you know, what's going on outside the plant and what's going on inside the plant.
The inside the plant it's a buffered environment that changes very slowly compared to the root of, a grapevine. what we've done is we've looked at the microbiome of vines that we planted in the field and look at the rhizosphere microbiome, or the, the The macro bill community associated with the root and the macro bill, community associated with the trunk, the graft union, and so forth.
And we see right after planting that the microbial communities associated with the root changes really quickly, whereas the the microbiome in the trunk are the graph union. changes very slowly. whatever growers do and cultural practices that they implement in the vineyard will have a limited effect inside the vine or it will take years for this to see the effect.
the rhizosphere microbiome drive a lot of, of biological function, you know, they, they, they fix nitrogen metabolize phosphorus detoxify compounds and so on and so forth. So there's a lot of, benefits of, using some cultural practices, beneficial practices and how they affect microbial communities associated with the roots.
[00:19:48] Craig Macmillan: We know that for like the pathogenic organisms, like the fungal ones, you know, they come in through wounds, whether that's a grafting or whether that's a pruning, we know that bacteria are introduced through things like piercing sucking insects. Like Leaf Hoppers and Peirce's disease. what is the, pathway for the bacteria and fungi that you find inside of a vine that are not the pathogens?
[00:20:10] Philippe Rolshausen: Well, you said it. the pathway is like from inside the vine, it's first of all inherited from the nursery. That's, that's the main pathway.
And then. Some of those organisms come from the soil, there's a fraction that comes from the soil and move throughout the plant systemically through the sap, the plant sap. So that's another pathway one of the major pathway. But again, that takes time. Right. And then, you have fewer introduction that comes through, you know, the plant natural openings, stomatas on the leaves, for instance.
Right. Or pruning wounds. Some organism when vines are pruned some organism common pruning wounds and are able to colonize down into the vascular system. That's another path. Or introduction through insects. And, you know, OSA is, you know, one of the best example of that being introduced with shop shooters. during feeding So, but I would say those, are minor introduction compared to what's already there when the vine is being planted and secondary to movement you know, sap movement throughout the plant, from the root to the upper part of the plant.
[00:21:29] Craig Macmillan: One thing that I saw mentioned is that these variations in The microbiome inside the plant may also have kind of a role in our concept of terroir in terms of how different areas have different characteristics. Is there, something to that idea?
[00:21:46] Philippe Rolshausen: the characteristic of wine region or the terroir is not only linked to the soil, the variety or the weather condition.
. It's also linked to the microbial communities associated with those vines. There has been a study that's very famous that was done 10 years ago at UC Davis that showed that. But it's mostly true for organisms that live on the plant surfaces the surface of the berries or the surface of the leaves.
It is not so true for organisms that live Inside the vasculature of the vine, just because of what we've talked about, just because it takes time for those communities to change over time. really those the microbial composition of the trunk is, from what we understand today, mostly inherited from what's coming from the nurseries.
you know, nurseries have a huge impact in shaping. the microbial communities of the trunk and the vines and you know, can you talk about terroir when it comes to the endosphere of the vine? I don't think so. I think it's, it's a debatable question. I think it's mostly true on epiphytic organism, organism that live on the vine surface just because they are more subject to the environment. Whereas it's not so true for trunk organisms,
[00:23:11] Craig Macmillan: , Even though we've been talking about the endophytic side, what's some of the things that the other parts do you were just talking about, we have a different community in the environment that's on the surface of the plant and that, that has a role in, you know, differences between regions in terroir. What impact are those kinds of organisms having on the physiology of the vine that contributes to those differences?
[00:23:35] Philippe Rolshausen: Well, that I don't know because, you know, that's not the field I've studied. But they, could influence the fermentation process, but I'm more interested in the one that live inside.
Do they have an impact on the wine quality itself, perhaps, you know, that's a question we're interested in. they have an impact on disease. We know that much because they, they affect disease outcome and we've shown that.
The question also, I think, from the standpoint of A grape grower or a winemaker is like, well, do they also affect winemaking?
we found some bacterium in the sap of grape vines that are present during the fermentation process. So lactobacillus, for instance we found those in the sap of grapes and some bacteria that also that spoil the wine fermentation process will also. Found them in the sap. So the question is like, are those, are those coming from the soil?
You know, where are they coming from? We find them in the sap and then can they go inside? Can they be moved to the berry of the grapes and then participate in the fermentation process later on? We don't know the answer to that question. The only thing we know so far is that we can detect them inside the plant stem.
And so. What is the impact? That's the question mark, but those are really relevant questions questions we're interested in because, if you can connect the root system to the cluster, and then if you can influence the root system or the microbial community of the root system, then perhaps you can influence the communities living in the cluster and then, you know, Later on, influence your fermentation process.
So that's the idea behind it. It will take time to decipher those questions.
[00:25:27] Craig Macmillan: Coming back to the pathology side. we have testing programs for virus in the nursery system. And we have the ability to test for fungal diseases, of course.
Do you see a role for testing for bacteria and fungi other than the pathogens at the nursery stage?
[00:25:48] Philippe Rolshausen: I don't think it makes sense. So we've been working with nurseries for several years now. And we are looking for where diseases are coming from prior to vineyard establishment. there's no certified program for fungal diseases and some bacterial disease like Crown gall.
there is a fraction of those pathogen that is coming from the nurseries. That's a fact and this is true for California, but this is true for everywhere else in the world. So if you get any. any vines from a nursery, you are going to find fungi causing grapevine trunk disease. And the reason is that there are over a hundred taxa of fungi causing grapevine trunk disease you will likely find one of them and not only that, but they are able to live on a different environment. And so they can live in soil, they can live in water, they can live in plant debris for some of them. And so you cannot get rid of them. I think that growers have to have the mindset that you are not going to be able to have plants free of pathogens causing fungal, grapevine, and trunk disease.
That's just not possible. Viruses, you can get rid of them and there is a certified program that works for that. This program would not work for fungi. It's just not realistic. Right. It would be too costly to do it. Right. Right. Right. Right. The question is like, can you live with it, right? Do pathogen causing grapevine trunk disease will cause the vine to die?
If that were the case, you would have no grape production in California because virtually all the vines are infected with one fungus causing grapevine trunk disease. that's not the case. It happens, it's called young vine decline, you know, when sometimes growers plant their vine. And the vine dies within five years.
But this is because what we understand now is that it's related to the stress factor that I was talking about earlier. there is something going on with the environmental stress that caused the vine to decline after five years. what we've done is to monitor the microbiome and the vine, like I've told before, following planting.
And we do capture those pathogen from the nursery to the vineyard. And they are evolving in the vineyard just and we can detect them. But under no stress conditions the vines are doing just fine. So every year a vine will lay out new wood, right? It will grow out some wood. The trunk gets bigger and bigger.
the fight between the trunk disease pathogen and the vine is if the vine can grow wood faster than it loses some to trunk disease, then it's fine, you know, it will be able to survive. Plants and grapes are able to compartmentalize the infection. They lay out walls to compartmentalize infection, and if they do that successfully, you know, Then they will survive now when you have a stress factor that comes into play and here you have to Go back and define well define stress this is where we go back and go back to your question about what stress are we talking about?
Heat a drought I think overcropping can be one of them also, when growers take tend to push the vine early on after the establishment to get into production quickly after two years. I view this as a stress factor, so this will influence the microbiome of the vine, living of the microbiome living inside the vine, and as a result, it will influence disease outcome.
[00:29:34] Craig Macmillan: I will not look at grapevines the same way. , is there one thing, one takeaway from this conversation that you'd like growers to hear
[00:29:44] Philippe Rolshausen: what we're trying to do is to identify cultural practices that are beneficial to production.
I think you, you have to look at it from a probiotic or prebiotic. Standpoint, just like we do for humans, you know. when you look at the prebiotics, those are similar to the cultural practices that you implement in vineyards to support the presence of beneficial organisms. that can be, you know, adding compost to your soil or cover cropping because they provide some benefits to the microbes living in the soil, and as a result, the microbe associated with the vine.
that's one of them. The probiotic is the addition of single microbes to the system identify which one of those probiotics using the metagenomics approach. And we've made some some stride in, in, in that research, we've identified several organisms that are beneficial to the plant and that are antagonistic to some of the disease.
So for instance Pierce's disease we've identified several organism living inside the vines that are antagonistic to PD. And today we are testing those organism in field trials at UC Davis. Because we've demonstrated that they, they work on the greenhouse condition. And now we moved on to field trials.
And when we inoculate those beneficial organisms to, or those probiotics to vine, they are able to stimulate the vine health in some capacity, or are being antagonistic to the pathogen in some capacity. And the vines are able to sustain the disease. So, the takeaway message from that is that we are making progress, you know, understanding what those probiotics and prebiotics are for viticulture.
[00:31:39] Craig Macmillan: That is great. and I'm really happy, That you're doing this work. It takes time Oh yeah, It takes time. Absolutely, that's, and that's, part of what we do here is we, bring people kind of what the future is looking like and what's possible because if you understand it, then when it does come along, The learning curve is already hopefully down the road a little ways. doing your homework, basically. thank you in your lab. This is really exciting. interesting stuff. Where can people find out more about you?
[00:32:09] Philippe Rolshausen: Well, they can go to the University of California, Riverside Botanical and Plant Sciences website. I'm a faculty member, so they will find me there.
I have also my personal website. Rolshausen. Slash lab. com. The problem is like the spelling of my name, right? It's not easy to do.
[00:32:27] Craig Macmillan: We'll have a link to that show page plus A a number of your recent publications.
[00:32:33] Philippe Rolshausen: Yeah, we have several publications about what we've talked about today.
We have just had one released about how pruning practices affect also the microbiome and, and disease. So. You know, this is an active area of research. I'm not the only one doing this. Like I've said, I've collaborated with Dario Cantu at UC Davis. And I think he should be mentioned because he's doing some excellent work.
And we are a great team working together. As a cooperative extension specialist, I collaborate with others. I collaborate with other faculty. And this is a collaborative work that I'm talking about. I'm not the only one,
[00:33:11] Craig Macmillan: there's a network. want to thank our guest, Philippe rolshausen. He is professor of cooperative extension with the university of California riverside and doing some very exciting work. And thanks for being on the podcast, Philippe.
[00:33:24] Philippe Rolshausen: Well, that was great. Thank you for having me.

[00:02:00] Craig Macmillan: Our guest, today is Kelpie Wilson. She's the owner of Wilson Biochar Associates, consulting and manufacturing. And as you may have guessed today, we're going to talk about biochar. Welcome to the podcast, Kelpie.
[00:02:08] Kelpie Wilson: Thanks. Thanks for having me.
[00:02:11] Craig Macmillan: What exactly is biochar?
[00:02:13] Kelpie Wilson: Biochar is just charcoal, but it's special charcoal that, uh, you can use in soil or for purposes of carbon sequestration. That's the official definition from the International Biochar Initiative.
[00:02:27] Craig Macmillan: And what does biochar do for us in the vineyard?
[00:02:30] Kelpie Wilson: Well, it sequesters carbon, so it's a very stable form of carbon. Uh, Carbon comes in a lot of different forms. I mean, we're all made of carbon, and, you know, carbon can be a diamond, which is really stable, or it can be in a sugar, which, uh, you um, oxidized into CO2 pretty quickly. So uh, in is very, in a very stable form um, it's called aromatic carbon, so it's fused carbon rings.
which are the basis of all organic chemistry. biochar is. It's carbon. The thing about biochar and charcoal is that charcoal can have, you know, widely ranging different properties depending on how you make it and what it's made from. And I should add also that uh, in the definition of biochar, For use in soil or for use in carbon sequestration, it needs to be made from organic you know, that is clean.
So there are some environmental kind of limits around it that ensure that it's, it's really contributing to the carbon cycle in a positive way and that we're not making Materials that have, you know, toxics in them that could hurt soil.
[00:03:41] Craig Macmillan: So we're introducing carbon in a fairly stable people have told me that the carbon that you put into the soil in the form of biochar could be there for thousands of years, but it's obviously available somehow, or it's involved in the soil microbiome somehow, or it's involved in nutrient cycling somehow.
What are some of the properties that contribute to that soil health component,
[00:04:00] Kelpie Wilson: Well, There's there's quite a few. The interesting thing about biochar is that it's naturally present in soils in many, many parts of the world because of fire, from vegetation fires, forest fires, it's it's supposed to be there in many cases. Uh, Especially here in the, in the in the west coast where we uh, natural fire regime in the forest.
And if you look at the most productive soils in the world, for instance, the mollisols in Iowa or the um, in the Eurasian steppe, they have large amounts of biochar Um, In the case of the steppes and the plains, that's because of prairie fires. So you have these tall, tall grasses that would periodically burn off very regularly, like every 10 years or so, and the top would burn off in a flame, and that heat would radiate you know, kind of just above the root zone, the grasses are bunched up really thick, and some air is excluded, so they wouldn't burn all the way to ash, but the heat would turn it to char, the flame would move on, and you'd be left with char, and so this char builds up over years and centuries, and, you know, hundreds of centuries to make this a very black soil and then there are other places around the world historically going back thousands of years where it was deliberately to add to soil.
So those are the terra preta soils in the Amazon naturally normally didn't have a lot of fires. And look, also can look at charcoal middens around ancient villages and even city states where people would dump their manure and their, you know, their hue manure, their night soil, and they would always deodorize it with charcoal and ash, and you find very fertile black soils in those places.
So, it's not a new thing um, but we just kind of recently rediscovered So, as far as what it does in soil, you know, it doesn't break down. Like, you know, you asked, well, then how does it feed the It it sets the table. So It's the stable carbon with these fused carbon rings. It doesn't break down easily.
And we'll also have the mineral ash. from the vegetation that burned. And so that's food. And then it also needs the carbs and the protein. So, and that comes from all the fertilizer that you add to it. So it basically sets the table for soil life because microbes like to sit down when they
eat. And so you have all these little surfaces.
In the charcoal, it's very, very porous. You know, think of activated carbon. People know that activated carbon is used for filtration. It's got all these pores. And so, in that way, it's kind of like a sponge. It can hold air and soil, which is beneficial. But also, there's the surface area. So, each of those tiny pores has a surface around it.
And when you add up all the surface area, and this is kind of mind boggling, It's But you take a teaspoon of, of or, you know, that's got a lot of surface area or an activated carbon and it can have a football field's worth of surface area all inside It's, you know, it's, it's, it's amazing to think about, but all those surfaces are where the microbes can sit down and attach themselves.
And if we, if we have added fertilizer as well, there are nutrients and water. Attached to those surfaces by electrostatic attraction. So the microbes just can hang out there and, and it's all there for them. So that's how biochar promotes um, the soil food web by, uh, promoting the microbes. And then the their mycelia in there to, you know, get it's a foundation of good soil.
[00:07:42] Craig Macmillan: And you were talking about the fertilizer part. Is that one of the reasons why it's a good idea or a common practice to mix biochar with compost and spread it in that form?
[00:07:50] Kelpie Wilson: Yes, but I would not just mix it with compost if I have any choice at all. I would put it in the beginning of the composting That's where you're going to get the most benefit know, it just takes time for all these things to come And so If you start it from the beginning, not only do you get the nutrients and the biology in there right you're um, having um, beneficial impact on your composting So, You'll have fewer greenhouse gas uh, the compost will get hotter quicker uh, and you know, the char will absorb any kind of nasty stuff that's in there, reduce odors, etc. it's really, The thing about biochar and to make it really work for you in a, in a farm um, is to get every, Benefit you can out of it.
And there's a whole cascade of benefits that come with biochar.
[00:08:40] Craig Macmillan: we can talk about that some more, but let's get to some practical things. Let's say I'm interested in this. I've been hearing about it. I'm excited about it. I want to try this out. How can I make some high quality biochar with the least amount of emissions and the highest biochar production on my farm?
[00:08:57] Kelpie Wilson: Great So I've been working on this for quite a while. When I first heard about biochar, it was, I think, 2007, and it was the terra preta soils that we were all hearing about. I immediately got involved in it. I went to work for the International Biochar you know, was in close touch with people all around the world.
that we're trying to find ways to start making and using biochar, and a lot of the first people to actually do it were people who uh, you know, making little cook stoves or just making biochar in burn piles, and I saw that myself because I live in the woods here in Oregon, and I'd go out to where they did burn piles to, you know, We had a lot of extra vegetation that had to be thinned to protect from wildfire.
And I'd go to these burn piles and I'd find little chunks of charcoal left in them. And so we started making, doing experiments to see if we could optimize that. And we figured out make, take a burn pile and light it from the top. So it burned from the top down, and that would burn up a lot of the smoke so it was cleaner, and also leave us with a little pile of glowing coals at the end.
And anybody who's made a campfire has seen this. You have that pile of glowing coals, and if you just walk away and leave it, it'll all go to ash. But if you just simply put it out with water, hey, you've got biochar. So that's the way to start, and you can can do it in your a, with a kettle grill.
You know, just a little container that will improve the biochar recovery because if you cut off the air that comes in from and the sides of your you, you will just burn less of it to And again, you just put it out with water. So then I started making containers to improve the efficiency.
compared to making biochar in an open burn pile, if you put it in a container, You can make three or four times as much so, I've been working with little containers ever those, We call those flame cap kilns. Because the idea of how they work is you put your, make your burn pile in a container.
It's cutting off air from the bottom and the sides. So all the air comes from the And as it burns down, you keep adding more. And every time you add more material, it flames up. And the char that you've already formed on the bottom is protected from air by the container. And it's protected from air from the top because all the air that comes in is used in the flame of the currently burning material.
And so what you've already made is, is protected from oxygen. So you can build up a huge pile of char in a container, and you're only limited by the size of your container, really.
[00:11:34] Craig Macmillan: So the practice is put your feedstock in a container something that cuts off the bottom the sides from the air Light it from the top with kindling or something I would assume something lighter weight and then as that process goes and you can see the material come back Well, is it truly combustion if there's not a lot of oxygen?
[00:11:51] Kelpie Wilson: Well, uh, I call it combustus interruptus. So basically it is combustion, but combustion happens in stages. Okay. myths combustion. One is um, wood wood burns, wood does not burn. Wood gas burns in a And you can see this if you look at your charcoal grill, you see, there's not a flame.
Because the gas has already been mostly, you know, burned out of it. And so it just glows. So there's different stages of combustion. The first one is dehydration. When you heat a stick of um, water's going to come off of it, because water doesn't burn. And then the gases come out, and those are, methane, carbon burnable, burnable gases, and those make the flame.
And then when the flame goes out, you know, you just, that glowing coal stage. So it's, it's really staged combustion, and you're just interrupting and saving the char.
[00:12:49] Craig Macmillan: If I understand you correctly by putting more material on the top I'm continuing that process. The stuff on this top is heating up. You're getting that, flame cap. So you described it. And I can just keep layering on until my container's full. Basically.
[00:13:04] Kelpie Wilson: Yep, that's how we do
[00:13:06] Craig Macmillan: I want to come back to the kiln idea, but first, what are the, what are good feedstocks to make biochar from? What are feedstocks that are not good for making biochar? Right. Right.
Uh
[00:13:19] Kelpie Wilson: Good feedstocks are dry.
You don't want a lot of wet stuff, because you use a lot of energy burning the wet. , Good feedstocks are also appropriately sized. So grapevines, for instance, are good because they're not really big. Even the trunk of a vine is not really big. And so if you try to put a big log in your container on your fire, you use so much energy to get the heat into the center of the log.
So it's a progressive thing, right? You're charring the outside, and the heat's moving in, it's charring and charring and charring. But meanwhile, the outside of your char is starting to burn to ash. So it's not very efficient to try and char a big log. The kind of limit depends a lot on the fuel moisture.
In Utah, we're We have really dry wood. People are putting six and eight inch diameter logs in a kiln and doing fine. In Oregon, I kind of keep it to four inches, usually. But you know, we could do bigger stuff. It's just not quite as efficient. So dry less than 25 percent moisture is ideal. We can do wetter stuff, and we often do because we're here in the middle of winter trying to get burn piles taken care of. So we go ahead and do it, and there's some techniques for optimizing how you do that, how you load it. But dry, less than 25%. and not too big, but also not too small. I've really tried hard to biochar hemp stalks, for instance, which are abundant around here, and they're just a little too small.
if they're dry, they do pretty well, but you have to really make sure you don't pack them in too tightly because, small, small things like straw, and crop waste like that, they will pack and cut off the airflow and you'll get smoke.
[00:15:07] Craig Macmillan: Oh,
okay.
[00:15:08] Kelpie Wilson: That's the main issue is you get smoke.
And then as far as what species, the main difference between different species of wood, for instance, is density.
And because we're making biochar in a flame, we're making it at a very high temperature. So it's, as long as we're not smoldering it, As long as we have the flame present, we know we're making it at a high enough temperature to burn out most of the volatiles. Know, some species like eucalyptus or walnut might have chemicals in them that are allelopathic, I think is the term.
And if you add a lot of that to soil, you could have problems. But as long as we're making it at high temperature, we burn most of that out.
[00:15:50] Craig Macmillan: Got it. So we want things that are dry. We want things that are woody, that are relatively high in concentration. Things like grasses are probably not going to work as well or work terribly well. It sounds like you want chunks basically, you know, something about the size of your forearm or a little bit bigger chunk would be a really
great, size.
[00:16:09] Kelpie Wilson: that's a great way to look at it. I like the physical measurements. You know, I was telling woofers here the other day about how to, make biochar compost. And so we're doing it in layers. And I just said, think about Parmesan cheese. When you add the biochar, if you really like Parmesan on your pizza, just add the biochar like that.
So those kinds of physical measurements are really helpful for people when they're learning how to use biochar.
[00:16:33] Craig Macmillan: and returning to that topic you recommend putting biochar in your composting windrows at the beginning as part of the whole process.
[00:16:41] Kelpie Wilson: Yes.
The very beginning when I think about a vineyard, especially one where you're actually making the wine know, you're pressing the grapes and you have the is it called
pomace? I think the grape skins that's easily degradable stuff. It's hard to, compost just on its own because it doesn't have much carbon, but if you add biochar to that, you can make a beautiful compost.
And then great for reducing on farm inputs. contributing to the circular economy. And that's always how I recommend people use biochar if possible, is find whatever other organic waste streams are there, whether it's grass clippings, grape pomace, leaves, anything else, manure that you might have, mix it right in there.
[00:17:27] Craig Macmillan: Makes tons of sense. Okay. Let's get down to the nitty gritty here. We've touched on kilns as a way of getting the highest production. Tell me about the Ring of Fire Kiln system the concept in general. And then what might, what might be a biochar production day like?
[00:17:42] Kelpie Wilson: The Ring of Fire kiln is my latest, greatest design. Just bin kilns, but they were heavy. So They were, weighing a lot, and you had to, move them around, and very hard for one person. So I came up with this modular design of panels. And so you can hook them together.
They're four feet long and 40 inches tall, and they have a bracket that hooks them all together, and you can make a kiln any size you want. with that. I mean, not too big, but usually we make kilns that are between six feet and 12 feet in diameter. And so that can accommodate the piles you already have, for instance.
And then the other innovation with that kiln is it has a heat shield. And that's really important for two reasons. One is it holds more heat in the kiln so you get more production. It's more efficient. But the other one is that it protects the worker. Because when you are around a giant , flaming pile, you know, you can really get fried just from the radiant heat.
You know, you're not burning up, but you, the radiant heat, I would come away from some of my sessions with very red skin and very dehydrated. And so we really think a lot about the workers who are doing this. Because it's mostly hand labor, although we can also load the bigger kilns with, machinery. that's the Ring of Fire Kiln. It's also very, very clean, and there's a gap between the heat shield and the inner ring that allows, um, air to come through, and then so you have preheated air that's going in from the top into the kiln. And that also helps a lot with, uh, Reducing the smoke. And I have lots of pictures and videos showing the smoke being sucked into the kiln from the top.
It's really cool to see these loops of smoke kind of coming up and then being sucked back down into the kiln. Those are the advantages of the ring of fire kiln in addition to the fact that it's modular. One person can take it apart and move it one panel at a time. The panels only weigh less than 40 pounds and set it up somewhere else.
That's, that's the other advantage of the ring of fire kiln. So a typical workday, and I'm going to quote some numbers from my colleague Eric Meyer, who has Napa char, and he's done some incredible work in vineyards in the last couple years. Here's what he says He can make up to 12 cubic yards of biochar per kiln per day, which is two bone dry tons.
And that is equivalent to two to three acres of pulled mines. he'll do this usually with one helper. Sometimes he'll have a, a mini excavator that he uses to load it, but a lot of times he's just doing it, you know, as hand labor. And so that's a ;lot of biochar, two tons of biochar in one day. He'll start by arriving at the site, setting up his kiln, and then just hand loading the biochar initially, fill it full, light it on top.
There's a little break where you let it burn down till you start seeing glowing coals at the bottom and, some ash on the top. And then you just load it one layer at a time. And the loading rate is really critical. If you overload, you get smoke and you'll end up maybe even with unburned pieces in the bottom because the flame moves up in the kiln as you add more material and the bottom starts cooling off.
You don't want to leave any big pieces at the bottom. We load small pieces initially. And if you have bigger pieces, you would load them kind of toward the end or in the middle. And then when it's all full of biochar, or you're just done for the day because you're tired, you get some water out and you spray the kiln down with water just to cool it.
Then you open up the panels, and rake it out, and you spray it with water and rake it at the same time. So you end up with a big, big patch of biochar on the ground.
[00:21:29] Craig Macmillan: Perfect. Then you take that to your composting spot and away you go. .
[00:21:32] Kelpie Wilson: another piece about making biochar from vineyards, especially vineyard removals, is that a lot of times there's wire, trellis wire, in it. And you could have a big pile and you could build a kiln around the pile because you're not untangling that pile, right, with all the wire in it.
And then at the end, uh, you know, you pick the wire out of the char. You can use a magnet.
[00:21:52] Craig Macmillan: That's cool. What are some things that we should be concerned about not doing? If we are newbies to biochar production.
[00:22:00] Kelpie Wilson: Yeah, that's a really good question too. So, you need to know a little bit about your biochar. If you have a lot of ash in it, it can be alkaline. So if you have an alkaline soil, and you have alkaline biochar, you need to think about how you're going to apply it and maybe, usually composting will take care of any pH issue.
If you have an acidic soil, you might want to just add it directly. You know, take the most advantage you can get of that liming ability. You also don't want to add too much at one time, especially without composting it first, because it can, , lock up nutrients for a short time. Most likely you're not gonna have too much biochar for a, for a big field. Um, It's great to be able to do it a little bit every year. That's the best way to incorporate it.
[00:22:47] Craig Macmillan: Oh, and that's another question. I've seen different strategies here. Some folks believe that it has to be incorporated into the soil. Other folks say, no, that's good, but you can go ahead and spread it at the surface and you'll still get some benefits. Is that true?
[00:22:58] Kelpie Wilson: Well, it's going to depend a lot on what you're trying to grow. So the vineyard trials that I've seen using biochar, a lot of times they're putting it in at planting and they're putting it in deep in the root zone. That seems like a good idea to me. One thing I'll say is when I look at the literature, I read a lot of the biochar research literature.
There's some really interesting new material out about replant disease. So if you're replanting in a vineyard, you know, in an old vineyard, new vines. The soil can harbor pathogens that the older vines were able to resist, but the new vines have a hard time with. And biochar has a lot of benefits for disease resistance, just because it promotes a lot of microbial diversity, so you don't get the dominance with some of the pathogenic fungi and other organisms.
So, you know, adding it, deep You know, when you're doing the replanting, replacing a vineyard is probably the most beneficial way, to add biochar. But if you already have a vineyard and you're using cover cropping, for instance, it'll go really well with a legume cover crop like clover and you don't even need to compost it because clover and legumes fix their own nitrogen and And biochar is especially wonderful with legume crops because it promotes the nitrogen fixing bacteria. If I just had a couple bags of biochar and I wanted to use it right away, and I was, planting a cover crop, I'd just use it in the cover crop. I think vines are like any other plant, where they have roots that come up close to the surface, they can get benefit from surface applied biochar as well.
[00:24:39] Craig Macmillan: So if I'm following this idea, so from a cover cropping standpoint, what am I going to do is broadcast it and then plant my cover crop. That'd be one way of building the health of the whole floor, which is a really good idea. What about banding? It's very popular to band compost right into the vine row.
If I have compost that's got biochar in it, will I get those benefits as well?
[00:24:59] Kelpie Wilson: I would totally think so. The other thing about biochar is that it holds water. So, you know, in, droughty areas that would be helpful to,
[00:25:08] Craig Macmillan: If there was one thing, just one piece of advice that you had for folks, Who are interested in starting to produce biochar and use biochar. Let's talk about it one for production and one thing for use. What would that be? What would that two part advice be?
[00:25:25] Kelpie Wilson: first of all, uh, get one of my ring of fire biochar kilns. It's a, you know, it's really economic. And second of all, buy my book, the biochar handbook, because I have all kinds of information in there about composting, you know, different ways to culture biochar, build soil. Well, you know, so sorry to be so nakedly promotional there, but
[00:25:50] Craig Macmillan: Well, you know, you're directing, you're directing people towards resources,
[00:25:53] Kelpie Wilson: right.
[00:25:53] Craig Macmillan: Anything else?
[00:25:54] Kelpie Wilson: Oh, well, I'll send you some other resources, too, that you don't have to buy the book. Check out the U. S. Biotar Initiative website. There's a Biotar Learning Center there and USBI has collected a lot of resources there. fact sheets, their seminars, webinars. There is a lot of biochar information out there.
And I will say I've watched a few YouTube videos that are just. Make me cringe it is so easy to experiment with it yourself, which is great. It's really great that people experiment with it. And I think, feel free, you know, do your own experiments. , there's some not so great information out there that, you might want to just do your own work and look at the more authoritative sources like that the USBI before you take what a YouTuber says as, as gospel about biochar.
So I guess my one advice really on both, topics of production and application is just jump in and try it. It's so easy. You know, make it, make a bonfire in your backyard or, any kind of little container. You could dig a little shallow pit in the ground and, just make some biochar, then you've got some.
Now do some, greenhouse trials. You know, see how it interacts with your soil because every soil is different. And so, check the pH, add it to, you know, your soil, and, grow a seedling. it's very easy to do some experiments. I actually have, in my book, a whole procedure for how to do a, scientifically valid experiment. Uh, Pot trial in the greenhouse, so you can really, step by step, you can really look and see how it compares with other amendments, try it in your compost pile, use a compost thermometer, it's not straightforward how to use it in compost, because again, compost like soil, it's going to have a lot of different kinds of ingredients, biochar does really interesting things, in compost, so.
Just try it.
[00:27:46] Craig Macmillan: Just try it. Like that's great advice. Our guest today has been Kelpie Wilson. She's the owner of Wilson Biochar Associates Consulting and Manufacturing.

[00:00:00] Customer sense of urgency around climate change is rising. In fact, 78% of global consumers feel that environmental sustainability is important.
[00:00:10] Welcome to marketing tip Monday with sip certified. We know customers are looking for wines labeled as sustainable while our longer form episodes help you learn about the latest science and research for the wine industry. These twice monthly micro podcasts will help you share your dedication to sustainable wine growing.
[00:00:29] Customers like the idea of being sustainable and want to live more sustainable lives. While, many brands and retailers today are making eco-friendly claims. Some chalk up to little more than greenwashing. A marketing ploy designed to make products seem more sustainable than they are. Because of this consumers can feel that they can't always trust green claims.
[00:00:50] It is more important than ever for sustainable brands like you to share your sustainable story in a meaningful and authentic way.
[00:00:58] In this week's marketing tip. We share a great example. With Niner wine estates, sustainable story on the value of energy efficiency.
[00:01:06] Electricity use in the winery accounts for a large proportion of the end products, energy demand. From keeping buildings and tanks at proper temperatures to powering equipment and lighting energy use in the winery adds up quickly. Anticipating increasing energy demand and cost. Niner wine estates built its winery into a hillside. Because of this, the ground level on one side of the building is a couple of stories higher. Then the ground level on the other side. This wasn't a flaw in the design, rather, a strategy to allow for a gravity flow winemaking system. are brought into the facility at the top level, instead of being transferred by machines, the grapes move with gravity down the tiers of the building through each stage of the winemaking process.
[00:01:51] Another other energy efficient benefit of the hillside is that the earth surrounding the building works as a natural insulator, reducing the need for a cooling system to keep the facility at optimal temperatures. is another element that Niner wine estates utilizes large windows in the production facility and tasting rooms allow sunlight to fill these buildings during the day. When they do need electricity. The grid is not their primary source. Since 2015, the majority of their tasting room restaurant. Wineries and Wells have been powered by the sun. There are two banks of high efficient solar panels on the property. One at the top of their winery building and the other on the ground next to their tasting room.
[00:02:33] Additional solar panels can be found in the parking lot, but they aren't used to power business operations.
[00:02:39] solar banks are on top of EVs charging stations, welcoming staff and guests to plug in while they enjoy their time at nine or wine estates.
[00:02:47] Together. All of these components have a significant impact on Niner wine estates, energy efficiency. them to symbols of sustainability, achievement, sip certified and lead a certified level. Silver.

[00:01:56] Craig Macmillan: Our guests today are Duff Bevill and Brooke Parsons. Duff is owner of Bevill Vineyard Management in Sonoma County. And Brooke Parsons is Viticulture Analyst with Bevill Vineyard Management. And we're going to talk about the Ford Pro Pilot Project that they're involved in. Thanks for being on the podcast.
[00:02:19] Duff Bevill: You bet, man.
[00:02:19] We're happy to be here.
[00:02:20] Craig Macmillan: So Duff, what exactly is this project? How'd you get involved in it? Give us a little history.
[00:02:26] Duff Bevill: Yeah, back in I think it was September, October of 2021. Well, I'm involved with the Sonoma County growers organization and Carissa Cruz, our president and Carissa.
[00:02:37] Got a name of somebody to call. And she made a cold call to a Ford motor company. And then I think one more phone call after that. And she got in touch with Ford pro told him what we were interested in doing. Thought whether it was a perfect fit because our sustainability program that we've you know, managed now for more than a decade, well over a decade.
[00:02:54] And Ford sent someone from Detroit out here to meet with us over dinner and another representative out of Sacramento that was, I think, a lobbyist for Ford, I can't remember exactly. His role, but both of them came out here and she cold called a couple of us to come and have dinner with his middle of harvest and yeah, we hit it off and she went back to I guess, technically Dearborn and told them back there that we were legitimate and she thought that they should pursue something with us.
[00:03:19] So that, that was in September, October, then in November around Thanksgiving. A team from Ford came to meet with us. They want to know size of our fleet of vehicles. They're just trying to get some, to find out how legitimate we might be. And they went back positive. And then the following January, so it'd be January of 2022 Ford came out full blown to Sonoma County, out to the Dutton Ranch.
[00:03:43] And we had a big, giant press release. President Jim Farley came out from Ford, all on film, gave a talk and that sort of thing, and it was a big deal. So that really launched, it's really January of 2022. Roughly probably March, I think it was, of 2022, they didn't have the lightened pickup trucks available yet.
[00:04:01] That was still, suffering from COVID, you know, and, and Production was down. So , they actually had some Ford vans, electric vans, which they just gave us a try and Brooke she was basically assigned that van and tried to figure out what to do with it. And so we, all collectively came up with an idea on how to use the vans, although you know, they're just not a fit for farming, but we made, we made it work out.
[00:04:23] And then I think it was in June, we finally pick up the lightning. So June of 2022, we've got the lightnings. And then what we did was we gave Ford feedback. We met with engineers, either Zoom or in person on a pretty regular basis for the better part of a year. More than a year probably.
[00:04:40] Just getting feedback from a farming point of view, you know, from us using vehicles in the field. And each one of the three companies used them differently and to gather information. I personally wanted to drive it so I could see. How it would work if I want to buy more, would actually work for me .
[00:04:56] I know one of the other companies used to have their shop mechanics use it and another company had one of their field foreman use it. So all of us really tried something different with it and for different reasons. But anyways, that's how it worked out. And we just fed information back and forth, making recommendations, you know, see if there's any flaws that Came up and we'd report back immediately to them.
[00:05:14] We saw something that Could be improved or or ask why it was the way it was that sort of thing
[00:05:20] Craig Macmillan: And we're talking about a completely electric vehicle that's designed for farm use Is that right?
[00:05:25] Duff Bevill: The concept of ford pro so I got my ford hat on right now the concept of ford pro It's a division that was created to really focus on business people with fleets so farming was a connection I don't think they thought of until we reached out to them.
[00:05:42] I think on paper, originally they were looking at the local contractor. You know, the guy was he drove it personally, he was the contractor, or he had a couple carpenters working for him. I think that was probably it initially. Whether they were thinking of farming at all until we reached out to them.
[00:05:58] I don't know. They almost certainly weren't thinking of wine grape growing on the west coast. I think that the whole name Ford Pro, it was really targeted to professional business people who would normally have a pickup truck and how they could adapt using electric vehicle.
[00:06:15] Craig Macmillan: I wasn't familiar with this until this came up for this episode. Is this product line is, is that commercially available at the time that you approached them? Is it available now? Is it still in kind of a testing state?
[00:06:26] Duff Bevill: They weren't available yet, but they were marketing in the summer of for sure the fall, but certainly the summer of 2021.
[00:06:33] I saw ads on TV or Something that would pop up on a website. If you're on Googling something else on a Ford pro for a lightning come up for 10 seconds and disappeared on it. It was a little bit of a tease at that point. But I know the one I got or the one that we have now was number one Oh nine.
[00:06:48] Craig Macmillan: Okay.
[00:06:49] Duff Bevill: I used to kid them asking, tell them I wanted number one, but they wouldn't give it to me. But I got number one oh nine and, they were just beginning to market it you know, shortly after Covid hit. And so they continued to in, in 2021, you know, we were basically all shut down in 2020.
[00:07:05] And 2021 was still pretty disastrous, but they were but all their production facilities were shut down. I mean, they came to a halt just like everybody else. So I think they anticipated getting out there, marketing earlier, making it available earlier. But I think the biggest stumbling block was for, I think a lot of manufacturers, they just didn't have the chips from the big chip manufacturer in Hong Kong.
[00:07:25] And that was what it boiled down to. I think it was true for all the car companies. Yeah.
[00:07:30] Craig Macmillan: Yeah. I remember that.
[00:07:31] Duff Bevill: That was, you had to get that out there. And so they had a marketing plan. They created a division. They had a president of the division identified. The marketing team was in place.
[00:07:38] All the engineers were shifted to the Ford pro team. You know, we got to meet almost all those people, I could, make a phone call to one of the head engineers anytime I wanted to, or send them a text or an email.
[00:07:49] Craig Macmillan: Wow.
[00:07:50] Duff Bevill: It was a real interesting experience.
[00:07:53] Craig Macmillan: And you said you got a van first, is that right?
[00:07:56] Duff Bevill: Yeah, Brooke drove it, yeah.
[00:07:57] Craig Macmillan: That got handed over to you, Brooke. What was that like? Did you have experience with electric vehicles prior to that? Did you have experience with vans prior to that? Were you, Pickup truck person.
[00:08:05] Brooke Parsons: Good questions. Yes. I had never driven a van much prior, especially for viticultural tasks. Before using the e transit, I used a pickup with a trailer that I would load a four wheeler onto the trailer and the e transit took the place of the trailer and the pickup. So I loaded With a ramp. The four wheeler inside.
[00:08:31] Craig Macmillan: Oh, it was a pretty good sized vehicle then.
[00:08:33] Duff Bevill: Yeah. A half ton chassis. It was basically F-150 chassis, but the van, you know?
[00:08:38] Craig Macmillan: Oh like a panel van.
[00:08:40] Duff Bevill: Exactly.
[00:08:41] Craig Macmillan: Oh, okay. I was thinking like in a condo van.
[00:08:44] This is more like a panel van. You got room to put stuff in. That makes sense. More like a, more like a service truck.
[00:08:48] Brooke Parsons: Like a service truck. So I'd open the back of it to load the four wheeler, but I could also open the side to access my tools and whatnot. It was nice.
[00:08:59] Duff Bevill: They actually outfitted it with shelving. Which would have been perfect if you were like a plumber or an electrician. But with the shelving it made the bay too narrow that we couldn't even fit the four wheeler and ATVs, so we had to take the shelving out so we could use it for that purpose.
[00:09:14] You know, we just substitute trailer and a pickup truck for the van. But how long did you drive that van?
[00:09:20] Brooke Parsons: I drove it for one full season, so May or June through the end of harvest.
[00:09:25] Craig Macmillan: How did you find that? Cause you see that all the time. You see the truck with the trailer, with the ATV in the back.
[00:09:30] How did you find that moving up to a van? Did you find it easier to drive? More difficult? Were you not as confident
[00:09:34] Brooke Parsons: I loved it because I didn't have to worry about a trailer and I didn't have to unload it each night to put it in the barn. So I just closed it all up and it was safe inside the van.
[00:09:46] If I went anywhere. I felt safe to leave the four wheeler locked inside and it wouldn't be tampered with. It was simple enough to bring back to the shop and charge every day and be ready to go the next morning.
[00:10:01] Craig Macmillan: That was gonna be my next question, Brooke. So when you first started with this, did you have any concerns about range?
[00:10:05] Duff Bevill: All of us do.
[00:10:07] Brooke Parsons: Yeah, that was the number one concern was range. For our operation, we farm all in Sonoma County and in a given day, I wasn't driving more than say a hundred miles in the van and it did make a difference in the range, whether or not I had weight in the vehicle or not, or if I use the heat or not.
[00:10:32] I didn't have as much range in the van as the Ford Lightning. And I had to be careful there were a couple of scary moments that I thought I'd have to call Somebody to come get me, but I never ultimately ran out of power
[00:10:48] Craig Macmillan: So with a little practice and a little experience, you knew
[00:10:51] Duff Bevill: If you were to buy a a ford lightning, I don't know about the other electric vehicles in the ford product line But for sure the lightning you would have a choice of, I think, two different battery packs.
[00:11:02] One they refer to, I believe it's just standard. And then they had a second option or an option that would be the extended battery. My understanding at the time, the Ford, pro version of the Ford Lightning came with a standard battery. But when they heard I was, you know, initially I was getting over 300 miles in a charge, I asked them about that and they said let us get back to you.
[00:11:22] Well, a week later they got back and said, oh yeah, that's right, we set yours up, or the three, but for sure mine, the one we still have, with the big battery. They sort of custom built that truck. These three are one offs in that first early run of the heavier battery pack, which to me and I suggested this to him, if the marketing is intended to be to the professional business owner driving a pickup truck, I think Ford pro should just be, you have a standard big battery in it for those reasons.
[00:11:50] They may do that. I have no idea. You're got a professional driver. He's in there going from. The lumber yard to the job site down to the Supply depot for something else. I would just think that's just based on our habits in the farming industry.
[00:12:03] You're shuffling around and it seems to me that'd be a good option, but anyways, It worked out great for me.
[00:12:08] Craig Macmillan: So you've been driving the lightning now for a little while, right?
[00:12:11] Duff Bevill: I drove it for the first two I guess nine months just so I could assess How I might want to buy more of them for , our operation here.
[00:12:19] We buy a couple of pickup trucks every year. I gave , the, pickup to Brooke. So she now drives the pickup cause we turned the van back in.
[00:12:25] Craig Macmillan: I figured that might get kicked back to you so Brooke now you've driven the van now you're driving the truck How do you feel about the truck?
[00:12:31] Brooke Parsons: It handles better than any vehicle. I've ever driven. I love to drive it. I'm very proud of it and I Like it a lot zero complaints
[00:12:41] Craig Macmillan: Even though you have to have a trailer again
[00:12:42] Brooke Parsons: Even though I have to have a trailer again, that's okay.
[00:12:45] Duff Bevill: It was remarkable how it seemed like it was luxurious riding because the electric horsepower, . That thing is so powerful. One of the things, again, my understanding of the engineers, they redesigned the chassis on it.
[00:12:57] So Ford that F one 50 has four wheel, all four corners, independent suspension. Soon as we got to, we put it up on the rack to take a look at the, Technology underneath it. Look at the batteries, you know, you're not touching anything, you're just looking at everything.
[00:13:10] And they designed this beautiful cast aluminum suspension for the back end of that truck. That you'd find in a, I don't know, luxurious European automobile, I think. But it's built heavy to handle all that, torque. You know, oh, it's like, I don't know, 800, horsepower when you push the special button on the dashboard, you know, and it's pretty stunning the performance and that's all torque.
[00:13:31] That's twisting power. And so the engineers had to design into that thing, something capable of handling that much torque is beautiful. But the point is a four wheel independent suspension just rides beautifully cars heavier. So about a thousand pounds heavier, I think because of the batteries. So the comments, the extra weight.
[00:13:47] And a very sophisticated suspension. It's just like a luxury sedan. And you're driving pretty nice.
[00:13:52] Craig Macmillan: And so Brooke, you've been driving this truck now, one of the things that has come up around electric vehicles has been the question of horsepower end of torque.
[00:13:59] How do you feel this truck performs compared to like, let's say a diesel dually,
[00:14:03] Brooke Parsons: It accelerates very quickly, so getting onto the freeway is no problem when it's busy. And the other biggest factor that I notice is braking. You hardly have to brake and it takes a little bit of time to get used to because when you take your foot off of the accelerator, it naturally stops because the engine isn't going.
[00:14:29] And you hardly have to use your brakes, which is very nice.
[00:14:33] Duff Bevill: When I first got it, my wife had a Prius many, many years ago, and she pretty much drove it right off the lot. The way it was set up from the dealer. Well, I discovered that you could switch to regeneration on electric. So when you did let off the throttle, it would break by regenerating electric motors, regenerate electricity, put it back in the battery.
[00:14:52] Well, that's the first thing I did on this lightning. Find that setting I think in the nine months that I drove it I told the guys at Ford I said, I'll bet you I didn't touch the brakes ten times in those nine months
[00:15:03] Brooke Parsons: but to answer your question I've only pulled light things behind it and So I haven't really put it to the test in that way.
[00:15:13] Craig Macmillan: I was doing a little research on this and I understand that there's like a data collection and management component to this that's attractive.
[00:15:19] What can you tell me about that? Have you used that feature? It can tell you about your fleet, I guess?
[00:15:24] Duff Bevill: Aside from electric vehicles Ford was really interested in us, Using and learning to use, and hearing back from us, their telematics. That's what they call it, Ford Telematics.
[00:15:37] And I think it was initially launched with the Ford Pro division, where you sign up every vehicle in your fleet. We've got like 20 Ford pickup trucks, something like that. If you go back all the way, I want to say like to 2014.
[00:15:49] Prior to that, I'm not sure, but for sure, like 2014, the electronics in those vehicles have the capability of just hooking up to the telematic system. The Ford is promoting, and if you get it into your fleet and get your, your vehicles in entered in your fleet, you can monitor them. Of course, like GPS, that's what everybody's doing nowadays, but much more than that, your shop manager could know, have a better use of knowing when it's time for an oil change, you know, we just do it.
[00:16:14] We track that kind of stuff, hard copy paper, put a sticker on the dashboard and the drivers relay to us when the mileage number comes up, they notify the shop manager and we schedule for a service. Typically the oil filter change and then in general inspection we inspect the brakes and all that kind of stuff.
[00:16:31] With the telematics they have the potential setting up where you could punch in a timeline that you wanted either by the calendar. Like every 12 months on the vehicles that we don't run very much. We do a major inspection every 12 months. And then the ones that actually have the mileage being for somewhere between five and 7, 000 miles, something like that.
[00:16:50] Depends on the vehicle. Depends on the tractor or it's a pickup truck or a full size class eight diesel truck. And so all that stuff is available. And one of the pluses and this happened to us. It was a perfect, we've used this as an example. Typically in modern vehicles, the components that fail first are the sensors that measure your NOX exhaust pipes.
[00:17:11] Those are the ones that are going bad. Probably because of the heat cycle they go through because of their exhaust pipes, right? So about anywhere between 40, 000 and 60, 000 miles, those are the devices that fail. So one of our foremen called the shop, our shop manager, and said check engine light came on.
[00:17:27] I guess he got the code through telematics, identified it as an oxygen sensor, ordered the part. The truck never came back to the shop. It's still out on the job site. We're supposed to be with the crew. He gets the parts ordered. The delivery guys bring the part to the shop that day. And it's interesting how it works is that is the analysis is it is 90 percent likely it's your oxygen sensor. They come up and then when the guy back that night, they bring it right into the shop and change that sensor. At the end of the day, confirmed that that was the part that needed to be replaced.
[00:18:00] The next day was back on the job site, all repaired. The only other way around that would have been. Bring it back to the shop. Get your, your analysis device on it, you know, on the onboard computer or mechanic drives out to the job site, does the same thing at the job site.
[00:18:16] And then it comes back or it comes out, orders the parts on a telephone or something like that. So it's saves time. There's no doubt about it. And there's a lot more to, manage a lot of the of systems we have already in place Ford doing the same thing with their telematics.
[00:18:28] So some of the things Didn't have any added value because we already have that kind of technology, but they were expanding a lot of that technology for fleet management. So that's a real plus. And they were constantly tweaking that in making improvements on the usability of it and that sort of thing.
[00:18:44] So that was a big deal. That was a big one.
[00:18:47] Craig Macmillan: The fleet management aspect of having an electric vehicle like this with this kind of a technology going into the future could be huge for a farm, could be huge for a management company like yourself that has properties all over the place. That kind of remote diagnostic is really amazing.
[00:18:59] The idea of like, Hey, the light's on. Okay, I'll fix it tonight. No problem.
[00:19:03] Duff Bevill: Well, the other big plus is when we put that lightning up on the rack, just to take a look at it, you know, we're just kind of noodling through the, , there's no oil to change in an engine. We found one plug access to a transmission on it.
[00:19:18] But even the owner's manual says don't touch any of that kind of stuff. You know, they can be serviced, but there's no schedule for servicing. The disc brakes, I don't think you'd ever If you use the vehicle to its maximum value, I don't think you'd ever put brakes in it. There's no transmission transitions made up of hundreds and hundreds of parts. It's not electric motors or a simple, simple mechanical device and the internal combustion engine has hundreds and hundreds and hundreds of parts that aren't there. So it has the potential of being over the ownership timeline of it.
[00:19:52] A lot less cost per mile. Even when you, you calculate in your Cost of electricity charge, but we have here and we've got solar panels here too. We already had installed From a number of years ago So we've got sort of that added advantage whether the electric vehicle made a little bit even more sense because we're already kind of using discounted Power
[00:20:11] Craig Macmillan: that was going to be my next question. i'm assuming your solar is connected to the grid So it's an offset so you're not islanded, but you still have the, you're generating power on your own.
[00:20:20] So you've got onsite power generation to power your fleet to a degree. That's brilliant. Yeah, that's fantastic. I remember years ago people were complaining about diesel engines and friends of mine were like, well, if you build us a solar truck, I'll freaking drive it. I got no problem with that.
[00:20:33] Well, here we are. What do you know? It's 30 years later, we have solar trucks, in effect. There has to have been some obstacles to adopting this. Were there some roadblocks or some things you had to learn along the way before you really felt like you were totally comfortable?
[00:20:46] Duff Bevill: Well, like I said, I was familiar with a hybrid.
[00:20:49] I still drive a hybrid. I drive a hybrid Ford pickup truck now. We had to get a charging station installed. Here at the office and then, you know, there's a decision. Do I do it at home or do the office? I wanted to hear at the office because that's where the fleet is parked and I had to think through, you know, get the one installed and how many more can I have and how many trucks will it eventually service without a major infrastructure redesign.
[00:21:11] So we've got that one put in and I, in the process, I had the electrician who was recommended to us. I had him install extra conduits underground. That are dummy right now. I assume we'll, we'll, extend for more pickup trucks.
[00:21:25] That was really the big obstacle. And then that's why I drove it because I want to know firsthand exactly what I was up against. I accomplished what I wanted. I want to learn as much as I could about it. Being there, having access to the Ford people, especially the engineers. Was on the fast track of having a better understanding.
[00:21:40] I got to talk to the guys who actually, one guy designed the grill, the other guy designed the dashboard. I mean, I was talking to those,
[00:21:45] Craig Macmillan: you had access. Yeah. That's, that's pretty amazing. Brooke, what was your learning curve? Like you talked about a couple of things, but were there obstacles that you felt you kind of ran across that you had to figure out, or that could be improvements
[00:21:56] Brooke Parsons: just forming the habit of charging.
[00:21:57] One time I forgot and. I was responsible for getting people someplace in the morning and it made me nervous. But you do that once or twice and you don't forget. So that was the real only obstacle. When traveling a longer distance, I did have to learn how to find charging stations that work well, are compatible with the lightning.
[00:22:25] And Ford is making advances in that area, now partnered with Tesla to use their system. And so that will only improve. But really it's around learning how to use the logistics of electric charging.
[00:22:44] Craig Macmillan: Right. And that's true for electric charging. For all of that. And you're right. I think a little bit of practice.
[00:22:49] Most of the folks that I know with electric vehicles, they're scared at first, and then they kind of figure it out. Now that you've had a chance to work with this, I think I already know the answer to this question. I mean, there's a question for both of you. When you were looking to your crystal ball, how do you see this technology being applied in the future?
[00:23:03] Duff Bevill: Think there's a place for it. I'm not so sure that one type of energy source is going to be the, solution for everything. I think practically, I think it's going to be some kind of a combination of energy sources and I don't discount nuclear.
[00:23:14] There's probably a place for everything, certainly in a transition period that that'll work best for all. Electrician put in the the charging station for us. He said, , if everybody's gonna go electric, the package must be solar panels, um, battery storage, either a large battery storage in a community setting, you know, like in a neighborhood or a small city size.
[00:23:37] Or you'll have battery storage areas that is appropriate, like maybe at our farm shop. Because we're commercial, we would be a candidate for battery storage, at least for our operation. So you'd have a solution for, you know, we're back to Sonoma County weather conditions again for the first time in quite a few years.
[00:23:55] I mean, it's overcast and rainy a lot of days out of the year. If you have solar panels, they're just not going to be working as efficiently and you still have to go to work every day and get your people to work. If you are relying. Let's say exclusively on electric, you've got to have something other than solar panel on the roof
[00:24:09] so windmill, solar panels, battery storage, there's some combination of multiple technologies. I just think that's sort of realistic of what it is. Do you want 95 percent of it to be coal? No, none of us do, you know, cause we all know the story there, but is, is there a place for coal for 10 percent of it?
[00:24:25] 15 percent of it. Don't know. I have no idea. It's good. I mean, we liked it. It's you know, just, we're not relying on it entirely right now, but we'll phase into it as time goes on.
[00:24:33] Craig Macmillan: Well, that was going to be, and and maybe Brookie also can kind of speak to this. I mean, is there a time when there isn't going to be a diesel truck on the farm?
[00:24:40] Duff Bevill: We're more concerned about diesel tractors. You know, the evolution went from, steam, you know, the early 1900s. The steam to, and then, you know, both in automobiles and, and on, on the farm, the competition was steam or gasoline because diesel wasn't invented yet.
[00:24:58] diesel engine wasn't invented until the 1920s. So turn of the century, 19th and 20th century, it was a competition between steam and gasoline, gasoline won. So gasoline surge forward all the way into the 1930s and with a few exceptions and in the 1940s, but by the 1950s. There was a clear transition that diesel was much, much more efficient, you know, pound for pound and horsepower for horsepower.
[00:25:24] I can't even think of where you could buy a gasoline tractor once you got in the 1970s. I'm sure you could still, but it represented a really small percentage. And by the 80s and 90s, it's all diesel.down to almost lawnmower size you can get it John Deere ride along more, you probably have a choice between gasoline and and diesel power to mow the golf course,
[00:25:42] that's actually transitioning to electric now too, you know, those, those small ones will plug it in and then mow for two hours, we're not even in the transition part of that story yet.
[00:25:52] There's a couple, manufacturers that have electric tractors the, inconvenience of them is really insurmountable right now, but changing batteries at lunchtime in your barn and that kind of stuff, tough. That's, tough technology.
[00:26:05] Craig Macmillan: It's still new. Yeah, this is still new. We're still finding our way there. I've talked to people about that topic quite a bit. It'll get better. Yeah, we'll see where it goes. Hey, Brooke, what is one thing that you'd recommend to listeners if they're thinking about adopting electric vehicles for the farm?
[00:26:20] Brooke Parsons: Would say be open to trying new things. It expands your mind and. It allows opportunity that would not be there otherwise. And be okay with mistakes. That's how we learn.
[00:26:37] Craig Macmillan: That's great advice. I think that's really, really good. Where can people find out more about you at Beville Vineyard Management?

[00:00:00] By acting environmentally and socially responsible today, we get future generations, a healthy place to call home. The actions that you as an individual take, have an impact.
[00:00:11] Welcome to marketing tip Monday with SIP Certified. We know customers are looking for wines labeled as sustainable. While our longer form episodes help you learn about the latest science and research for the wine industry. These twice monthly micro podcasts will help you share your dedication to sustainable wine growing.
[00:00:29] So you can show your customers that you share their values.
[00:00:33] The summer months, bring more staff and guests into tasting rooms across the country. Invite your whole team to join in your brand sustainability efforts. When you practice these five sustainable tasting room habits. Tip one is to conserve. Simple actions like completely shutting off water faucets after use and notifying management of leaks help conserve this limited resource. Turning lights and appliances off when not in use reduces electricity. Consumption.
[00:01:02] Although the commercial end use energy sector uses the smallest amount of energy of the four sectors, which include transportation, industrial, residential, and commercial. The majority of the energy used comes from fossil fuels, small efforts in the workplace, reduce reliance on non-renewable energy. Tip two is to recycle responsibly.
[00:01:24] We know the importance of recycling, but when heading to the bin with recyclables in hand, it's easy to forget the nuances. Some items can be recycled together, like cardboard paper and some plastics and metal. Glass is, usually recycled separately. And sometimes that's separated by color. It may be tempting to line up a recycle bin with a plastic bag. But it can actually be detrimental to your good efforts.
[00:01:48] Plastic bags can clog recycling machinery. Contaminate other recyclable materials and potentially lead to recyclable material ending up at the landfill. Instead, keep those items loose or use a paper or reusable bag to line the can. Your wine bottle corks can also be recycled and turned into many useful items.
[00:02:08] Start a collection container and send it off to be repurposed.
[00:02:12] Re cork has a map of drop off locations that makes it easy to find a cork recycling partner near you. Consider teaming up with neighboring tasting rooms to send your corks together. Tip three is to reduce and reuse. Upgrade to glass and metal dishes in the break room to cut down. On single use plastics, Sanitize and reuse water bottles for serving water. These small changes can drastically reduce your weekly waste. Tip four is to source locally. Check out local artists and small businesses for crafts, snacks, and knickknacks to offer for sale in your tasting room. This is a great way to introduce your guests to local talent and support your community. And tip five is to bike or carpool to work.
[00:02:58] There are several alternative transportation options available today For eco-conscious commuters. Trips can be shared by carpooling or using public transportation to reduce the number of cars on the road. Riding a bike e-bike skateboard or one wheel has The added bonus of getting your blood pumping.

In today's podcast Craig Macmillan, critical resource manager at Niner wine estates with a long time sip certified vineyard and the first ever sip certified winery. Speaks with Misty Oebel. Health and farm stress extension educator at Michigan state university. Misty works with a team to help farm workers manage depression and anxiety. Their educational initiatives, outreach and teletherapy, give farm workers who often live in remote areas.
Access to help without a commute or social stigma. Misty highlights the importance of community support, recognizing signs of stress and maintaining a resilient mindset through learned optimism. She reminds listeners that the farmer is the most important asset on the farm. Before we get into the interview, I wanted to share a message from Lupita, a vineyard team.
Juan Nevarez is Memorial scholar. She says my parents left Mexico to give my siblings and me a better future. I want to make them proud by finishing school and pursuing my dream of becoming a pediatrician and the Salinas valley so that I can give back to my community.
We know that higher education is important to many students, but paying for college could be challenging.
This unique program provides financial and support services to the children of California's vineyard and winery workers. So they can earn a higher degree. You can help a student like Lupita, make their dreams come true by making a gift. By visiting vineyard team.org/scholarship. Or look for the link in our show notes. Now let's listen in.
[00:02:35] Craig Macmillan: Our guest today is Misty Oebel. She is a health and farm stress extension educator with Michigan state university extension. Thanks for being on the podcast.
[00:02:44] Misty Oebel: Well, so much for having me.
[00:02:46] Craig Macmillan: And today we're going to talk about a concept called farm stress. When I first heard the term farm stress, I was thinking of farms that were stressed, you know, land that had been overworked or was in decline and that kind of thing, cause that's a lot of the stuff that I talk about and study, but that's not what we're talking about in this context.
What does farm stress mean in your world?
[00:03:05] Misty Oebel: So in my world, I'm focused on behavioral health. I look at providing education about stress, particularly chronic stress and its impact on the agricultural community. So I think it might be more accurate if we went by the term of like farmer stress or stress on the farm, but that's not the way it's titled.
So farm stress is what we go by.
[00:03:25] Craig Macmillan: One of the things that brought your project to our attention, and it's really extensive. MSU Extension is doing a lot of work in this area. It's really impressive, and we'll hear some more about that. Suicide rates are one of the highest in the occupations of farming and ranching of any occupations in the United States, actually.
Which a lot of people might be surprised to find out. And related to that, there's also very high incidence of Depression and or at least meeting the criteria for depression and for generalized anxiety disorder. And, you know, by these, I want to make sure that we're clear that, you know, we're not talking about simply being like, Oh, I'm sad.
Oh, I'm depressed, but actually things that impact your ability to function, your actual mental illness conditions
[00:04:05] Misty Oebel: Right. That's exactly right. When we're looking at these numbers a lot of we're studying it through self report. So it's asking questions. It's not asking a question like, do you feel depressed? It's asking a question like, are you having problems with your appetite? How is your sleep changed? How are your relationships with other people?
Are you experiencing irritability on a regular basis? Those are the kinds of questions that they ask. And then those are the criteria that they're looking at when they're saying agricultural workers are you know, we're finding that about 60 percent of the people that are participating in these studies are meeting the criteria for.
depression, about 55 percent for generalized anxiety disorders. So this is significant because that does impact your ability to function.
[00:04:50] Craig Macmillan: And are also risk factor for things like suicide and substance abuse.
[00:04:54] Misty Oebel: And that's exactly right. We see much higher rates of suicide rates amongst agricultural workers than other occupations. We do see, really high substance use rates as well. Alcoholism we see is reported with heavy use for alcohol amongst farmers is about 38 to 50 percent of farmers in America, which is pretty significant.
The other issue we see is farming or agricultural workers also have the highest rate of stress related death. due to disease. So that's a very major concern for us.
[00:05:25] Craig Macmillan: It's a major public health health issue. Issue around this. When you said you were , asking these questions, getting this, this data, how is this data being collected? How do we even find out, this is an issue?
[00:05:36] Misty Oebel: There's a preliminary study that's coming out of Illinois State University. It's being done by Rudolfi and Berg. They're the ones that are leading a lot of the information on this. And so there's the study that I'm going to quote most because those the numbers that are most they're the most relevant to me because I do work in the Midwest.
And so what we're looking at is we're just when we start to see those statistics like the high suicide rates, the high rates of death by stress related disease we start to see the amount of issues we're having with alcohol and opioids and even we're seeing some stimulant use. increase at this point.
Those are all things that start to trigger us to do a lot of research and try and figure out what this impact is and why it's happening.
[00:06:13] Craig Macmillan: And I'm guessing that is where the MSU extension managing farms for stress program came from.
[00:06:18] Misty Oebel: Yes, there was a significant need. The USDA was asking for people to participate in and start providing education and support for farmers because we were noticing that there were some pretty significant issues within the community.
[00:06:32] Craig Macmillan: This is one of those things that's true for a lot of areas of public health. How do you. Get to the populations that need the help because people don't always come forward looking for help or there the demand there? People are having issues and they're coming looking for help. What's the what's the the interface?
between the farm stress program and the target population
[00:06:56] Misty Oebel: Sure. So one of the things that we're doing through our program, we spend as much time as possible in rooms with growers. Speaking at a lot of conferences, speaking at a lot of meetings. We spend as much time as possible, putting our faces out there and trying to build that rapport.
And I have yet to speak in front of a group of people on a farm stress and not have people waiting in the wings afterwards to talk to me about that. So there is some face to face connection there. Sure. We also have people who hear about us through like news or hear a podcast or read an article and then they go looking for our website and then they connect with staff that way where they're reaching out to us and saying, I might need a little bit more help.
Can you help me with this? So that's pretty common. We also receive phone calls and emails from people all the time who say, Hey, my veterinarian said I should reach out to you or my accountant or, you know, my Miller, it's these people who they have professional established relationships with who are saying there's something that's not right.
right? There's something going on here and you need to talk to somebody about it. And so we connect with people that way. But I would say quite honestly, the number one way that we are connecting with people is we get an email or a phone call from someone who loves a farmer. So it's a parent or a spouse or a sibling who says, you know, my, sibling, he has this farm, he's been working on it for a long time.
He's really, really depressed and he's not doing anything about it. And we're getting really, really worried about him. So there's a lot of different ways that we come in contact with these farmers. I would say probably the number one way is because somebody noticed something was going on and then they connected them with the appropriate resources at that point.
[00:08:32] Craig Macmillan: And that's an important point the role of community and family and our social networks The old see something say something Sometimes it can be hard to do when it's a loved one and probably the most important to do when it's a loved one.
[00:08:42] Misty Oebel: I agree with that. Just this year alone, I've talked with six different families as they're surviving the loss of a loved one to suicide. And one of the things that keeps coming up is I noticed something was going on, but I didn't want them to be mad at me. I didn't want them to be upset.
I didn't want to hurt their feelings. And it's one of those things that I think we would all rather have somebody be upset with us than to lose that person. And so that's really important. If you see something, say something, notice something, refer them to somebody. It's also really important to start learning about how we can communicate.
You know, how to ask open ended questions, how to ask difficult questions and how to practice those active listening skills so that when somebody is answering the questions, you're hearing what they're saying and you're not just waiting for that opportunity to start talking again. Those are all really important.
There's trainings that we can offer through MSU Extension. There's an open course that's available on our website. It's called Rural Resilience. It's open to the community and it's free and it's online. So it's, it's really useful, but it's literally trained to teach you how to recognize signs of stress in yourself and how to manage that stress, but then how to recognize signs of stress in other people and then how to communicate with them and have positive communication that could be helpful.
[00:09:52] Craig Macmillan: So you mentioned this website. We just talked about how you kind of get in contact with the population. What are some of the other methods that you folks are employing around this to get people help? What is the kind of help that you can provide?
[00:10:03] Misty Oebel: Some things that I think are really useful, again, that referral process is really important to us. So if you know about us and then you see somebody that you care about is struggling, please let us know. Through MSU Extension, we offer a lot of other programs that aren't necessarily related to farm stress.
So it's not unusual for us to talk to like a field crops educator or a fruit crop educator, and they're coming to us and they're saying, Hey, I'm working with this farmer. And we're seeing these behaviors and I'm talking to them and I'm trying to get them to talk to you. That's pretty common as well. So those are all resources we have available.
We offer through the website, we offer a lot of things. And I always tell people if you're interested in the Farm Stress and you want to know more about our program, if you go to our website, and it's usually pretty easy if you type in like MSU Farm Stress. we're usually the first result. We come up pretty quick.
And that website has everything. It has articles we've written. It has educational materials. It has those programs like the training materials available as well, that online training. And then it also has a form that you can fill out for our teletherapy program, which is also really beneficial.
[00:11:04] Craig Macmillan: Yeah, so I was just gonna ask about that. So you are able to put people or connect people to talk therapy services either tell therapy or face to face.
[00:11:12] Misty Oebel: Yeah, it's actually, it's one of the programs we're really proud of. We have this opportunity to provide it to people who are connected to the agricultural community. And it helps because there's a lot of barriers within the farming community to getting, you know, mental health services. You know, most farming is done in rural communities.
So we know rural communities have less access to medical services, let alone behavioral health services. We know that then if somebody is interested in going to like counseling, it's going to take them longer to travel to a therapist. And then they're going to sit there and they're going to come back.
There's also some stigmas attached still to like mental health issues within rural communities. So you know, when you talk to a farmer and they say, you know, I just don't want them to see my truck sitting in that parking lot. I'm just really concerned about that. I don't want people to think something's going on.
And so teletherapy is a resource then that it removes those barriers for them. You can do it from the comfort of your own home on a laptop or a smartphone. They use cameras, so you're still able to see the person. You're able to have a conversation and talk with them.
It's completely confidential. And then it's a really great resource then because then It removes the barriers and makes it accessible to everybody. The other piece of that is sometimes one of the barriers is cost. That can be really prohibitive for people, especially farmers who are independently, you know, they work for themselves, so they're not always insured, you know, so this can be a problem.
And so MSU extension has the availability. We actually provide for and cover the costs for any agriculture workers within the state of Michigan. At this point, our funding is limited, but we're able to then cover the cost of that. So there's no cost to the farmer either.
[00:12:44] Craig Macmillan: How many folks are you getting in contact with? How many folks are taking advantage of this?
[00:12:48] Misty Oebel: At the moment, I don't have the numbers. That would be something my program lead would have. I just refer people. It is something that we refer people on a pretty regular basis, probably one to two a week we make a referral or we talk to somebody about sometimes more. So I think that that's a pretty good estimate that we are definitely reaching people this way.
[00:13:06] Craig Macmillan: And that actually just reminded me of something else. So is this referring folks to behavioral health professionals that are outside of the MSU system. Is this, is this program funneling folks to other existing folks or is this counselors and therapists and prescribers inside the MSU system?
[00:13:23] Misty Oebel: We work with partners. This is one of the things we wanted to do. Like for example, I have a background in counseling psychology. Our program lead has a background in psychology as well. We have the backgrounds in it, but we don't want to be doing therapy because that takes us away from that education piece.
So we refer to licensed therapists and it's been really good so far. I think it's been a really great program. We try to look for therapists that have a background in agriculture as well. We recognize the subculture of farming is unique, and we don't want to send them to people who are not going to understand where they're coming from.
We want to make sure that there's that background there already.
[00:13:56] Craig Macmillan: In your experience so far can you describe what some of the aspects of a agricultural subculture are like? Because I agree with you. I think there's very much some commonalities. And there's a cultural component that's different than other aspects of American life. What are some of the things that you've seen and what are some of the barriers that come from that?
[00:14:18] Misty Oebel: Oh, goodness. Yeah, there's a lot. There are things that are so unique to farming that you don't see literally in any other profession. You rarely see people who identify so much with their work as growers and farmers. People who, you know, It's so inherently ingrained into who they are. It's becomes part of their identity.
I could use an example. It's kind of how I came into the firm stress work. My dad grew up on a farm and, you know, just a little farm had six brothers and sisters, parents. They worked this farm and his father passed away when he was 17 years old. And within a couple of years, they realized that without.
Their father, they really couldn't continue the operation. They started selling equipment, selling animals and leasing the farmland. And when I asked my dad about it, when I was a kid and was asking questions about what it was like when he grew up, one of the things he said that's always stuck with me is he said, you know, it was really strange to be a farm kid without a farm.
Even after the farm was gone, he's still so identified with that aspect of his identity that it just. never occurred to him that you're not really a farm kid without a farm mate. He still was. And so that's very unique to farming. There's a legacy aspect of farming that we don't see in every other profession as well.
There is an understanding that this is something that we want to continue to go on. And we passed into the family. So kids are growing up knowing there's that expectation that, that This is going to be passed on and we will be taking this over. So there's that legacy aspect of farming. There's the idea that you're in a rural community, so you have fewer neighbors than people in urban areas.
So sometimes that can mean that you have really strong community nets, but other times it can mean that you feel really isolated as well. As we're entering a more modern area and we're seeing less individual farmers. I want to say it that way.
We're seeing bigger operations, less small farms that can also feel really isolating for farmers because less people understand what they're going through, less people are able to relate to them on that level. There's so many things that are so unique to this subculture. And and they're also just so, so much, when we say salt of the earth, we're literally talking about farmers.
They are the people who are out there day to day. They feed us. They're taking care of the land, and they take such pride in their work, and they're so conscientious about that work. I think that's really important to recognize. They're a completely different culture of people, and so I think it's really important.
It's really valuable that this work exists just for the fact that this is a culture we can't lose in our country.
[00:16:40] Craig Macmillan: Absolutely. And you know, having programs that say, Hey, we we understand you and where you're coming from, I think might help a lot. And I was very impressed by what I've seen online. It's very welcoming the way that it's presented. It can be very daunting to try to reach out for something that you've just assumed no one's going to understand, right?
And if you kind of get the sense that there are people there for you who understand who you are and where you're coming from, I think that definitely helps. There are a couple of things that I noticed that I thought were really cool. One thing is the idea of resiliency. A resilient mindset and a productive mindset are two things you have.
Materials about developing and maintaining and etc. Can you tell me about those two ideas? I just think that's just so interesting
[00:17:24] Misty Oebel: I'm gonna argue, and I'm always gonna argue this, that a resilient mindset is a productive mindset, because a resilient mindset I think we could define it, if we're going to define it just at its simplest terms, it's, it's learned optimism. I think there's already innate optimism when we're talking about agriculture anyway, because otherwise, how do you face a drought one year and then go back and do the same thing the next year?
You have to be optimistic. I mean, you just have to, it's innate. But I think that a resilient mindset is that learned optimism, which is we're able to accept that, you know what, things don't always go the way we want them to. Things often happen that we did not hope for. We face uncontrollable circumstances all the time, especially in farming, when you're dealing with weather or, you know, pests, things like that.
So we have to be able to accept when things aren't going well and still be able to move forward with the idea that things are gonna be okay, even though things aren't going well. Now they're gonna be okay and we're gonna get through it. I've survived everything up to this point. I'm gonna survive this.
I'm gonna go on to the next thing, and it might look different, but it could still be good. And I think that's that resilient mindset that we talk about. And there's so many benefits of a resilient mindset. You know it decreases depression and anxiety. We see better physical health because our cortisol and adrenaline levels, those stress hormones are lower.
We also see again that ability to move forward and to be adaptive and to be more focused on problem solving than getting stuck on just what the problem is. So that resilient mindset, I always argue this resiliency is is productive. If you're not resilient, you're going to struggle and you're going to get stuck.
And then you're not going to be very productive.
[00:19:02] Craig Macmillan: I'm gonna call on you as a practitioner now? What are some examples of techniques or tools or things that I can that I can do that. They will help promote this in myself
[00:19:11] Misty Oebel: The two most important aspects in resiliency is making sure you have that community. So making sure you're building a community, you're finding people who support you, who understand you and who care about you. That's the number one thing that is actually the most influential factor we have found in resiliency and whether somebody is going to bounce back from a difficult situation.
Community social connection. We actually find isolation is really, really dangerous. It increases depression and anxiety, it increases cardiovascular issues, and suicidal ideation goes up when people feel lonely. So, community is number one. The second thing I always argue is really focusing on that emotional health piece.
And we can do that in a lot of different ways. But one of the simplest ways is to start practicing those mindfulness techniques. And sometimes when I say that people are like, Oh, that's that hippie, dippy stuff. And I don't want to do that. You know but what we're really talking about there, did they just put a name to it?
It's just being engaged. It's just being present in your moment. Cause sometimes we get into the habit of. I'm stressed and I've got a lot to do and we get into this autopilot mode and we just keep working and we plug away at it and we feel really good because we just keep going. But when we're doing that, we also have to ignore a lot of other things that are going on and we're not really aware of what's happening.
So practicing mindfulness. Because practicing mindfulness allows us to be engaged enough to be aware of what's going well so we can be grateful. Gratefulness is really great for you know, resiliency. The other thing that it does is it allows us to notice when things aren't going well, and that allows us to do that problem solving and be like, okay, what can I fix?
And then if something can't be fixed, okay, I can accept this can't be fixed, it's out of my control. And that's also really important for resiliency. And then that third piece to when we're really aware of what our moment is like it allows us to be aware of our emotions and to recognize them as they're happening and to process them instead of doing the thing where we like are just shoving those emotions down because I'm busy.
So I'm going to shove it down and then I'm going to keep working and then another emotion flies in and you know what? I don't want to deal with that right now either. So I'm going to shove that down too until we blow up because we have just this overwhelming flood of emotions we've been ignoring. And so when we're practicing mindfulness, it allows us to process them as they're happening and they never get to that huge overwhelming stage.
And we can practice mindfulness in a lot of really simple ways. It's not complicated. It's not something that you have to go through a class or something to learn how to do. You know, it's a journaling. I'm going to sit down every night and write down what went well today and what didn't. It is meditation or prayer breathing exercises, really, really simple breathing exercises that just make you pause.
and stop and notice what is happening around you and in your body. That's it.
[00:21:53] Craig Macmillan: And I'm guessing You're communicating these ideas in various forms. I mean, there must be print form, there must be video form, there must be face to face form. I mean, are you doing clinics, trainings, newsletters? What are all the different avenues that you're using to communicate these very, very, very practical, very specific things?
What routes are you using to get those to people ?
[00:22:14] Misty Oebel: Like I said before, if there is a room with growers in it, we try to be in that room. We, we speak at every opportunity that we possibly can because we do want to make sure the message is getting out. We participate in podcasts. We write articles, we write a lot of articles. We are actually in the process of re updating a lot of our program materials right now to make sure they're all fresh and all the information is new and current.
So we do that. Those are all available online. The training programs that are available online. We talk to families who are in the middle of it. And so we talk to people on the phone. It's not unusual for us to spend an afternoon at a farmer's kitchen table. talking with them and figuring out what their next steps are.
Literally any avenue. So we have all of these print materials that are available, a lot of stuff available through our website, but we are also people who are available. Should there be a need for that as well?
[00:23:03] Craig Macmillan: Something else that I noticed that I thought was great is, you know, obviously farm stress doesn't just affect the adults that are involved. It also affects youth. And like you talked about this generationality aspect and how important it is. Just like you said, farm kid without a farm. It's farm kid.
You know, that's part of the kid. Can you tell us a little bit about that and how that's fit into your program?
[00:23:23] Misty Oebel: Yeah. That same study that I was talking about earlier by Rodolphe and Berg, as those numbers have come out, they also did study on farm youth. And what they found is that the numbers for depression are the same. About 60 percent of farm youth meet the criteria for general depression. We see slightly lower on generalized anxiety, it's about 45%. The number that I find really interesting, I want to know more about, is 62 percent are reporting the, the diagnostic criteria for separation anxiety, which is very, very interesting. Yeah, that one kind of throws me. I don't know where that's coming from, but it's really interesting. And I'd like to know more about that one.
What this tells us is that as parents and adults, we're not doing as good as we think we are and hiding how we're doing. It tells me we're not doing as good as we think we are in hiding, you know, when stress is occurring, when we're depressed, when we're anxious. Kids are pretty intuitive and they pick up on that.
I know my kids have called me out on stuff like that before and like you weren't hiding it as well as you think you were. So that happens. I think there's also when we go back to it, there's that legacy aspect of it where there's an understanding that if this farm is going to continue, somebody is going to step up, somebody is going to take over it.
And so you see really young kids who start assuming the responsibility of the problems. well before they really need to do so. So that is absolutely impacting them as well. I think it makes it really, really, really important for parents to be paying attention for those signs of stress in their kids as well as in signs for themselves and their neighbors.
They need to be paying attention. Are they showing mood changes? You know, are they suddenly really irritable? Are they having problems sleeping? Am I seeing differences in their appetites? Are they shutting down? Are we not talking as much as we used to talk?
There's a lot of things that we need to pay attention to when it comes to our kids just to make sure that they're okay and so that we're able to connect them with the support that they need earlier rather than later.
[00:25:13] Craig Macmillan: Is there one thing, just one piece of advice or one observation that you would recommend to our listeners around this topic?
[00:25:20] Misty Oebel: Can I go with two? Is that ok?
[00:25:22] Craig Macmillan: Two is great, do two.
[00:25:23] Misty Oebel: Okay. One of the first things I want to come back to. It's something that we've talked about a few different times. Is this idea of the generational aspect and the legacy piece? Because that is absolutely a barrier in farmers in, seeking behavioral health support.
There is kind of this idea of like, well, my dad was a farmer and he never saw a therapist and my grandpa was a farmer and he never saw a therapist. So is there something wrong with me now if I need additional support? And what we kind of forget is that depression and anxiety are not new. And if you're facing it, your dad probably had it too.
Your grandpa probably had it too, but they were struggling silently and never got the support that they needed. And I think that when we're looking at generational stuff, we always try to do it a little bit better with each generation. We want the farm to be a little bit bigger, a little bit cleaner.
We want to make sure that our processes are a little bit smoother. With each generation, it gets a little better and we do the same thing with parenting. You know, we want to be a slightly better parent to our kids than our parents were to us, and we hope that they do the same thing with their Children.
So I think that makes it really important that we recognize that just because past generations weren't receiving help, that doesn't mean we shouldn't receive help. It actually makes it more important because we're trying to prioritize that, and we're trying to make those changes in the family. So that's the number one thing I can think of.
And then the other thing, this is something I tell farmers all the time is the growers and the farmers that I know are very, very conscientious when it comes to caring for their land. And their animals and their crops and buildings and equipment, and they invest a lot of time and money into the maintenance of all of those things, because their assets but I'm always going to argue that the farmer is the most important asset in any farm.
And so I really feel very strongly that it's important that we prioritize caring for ourselves and we recognize that self care is not selfish. It's very important. If you're the most important asset on your farm, you've got to make sure that you're taking care of yourself.
[00:27:21] Craig Macmillan: I think that is a fantastic observation. Absolutely. Where can people find out more about you and more about the Farm Stress Management Program?
[00:27:30] Misty Oebel: I'm always going to recommend you go to our website. Not only do we have all of those great resources, but you can connect with staff through that website. We have all of our pictures on there. I'm on there. Dr. Remington Rice is our program lead. He is phenomenal. He has his information even in multiple places on the site.
So please reach out to us if you have any questions, thoughts, concerns want more information, that's the best way to get ahold of us.
[00:27:53] Craig Macmillan: Fantastic. Our guest today has been Misty Oebel. She's a health and farm stress extension educator with Michigan State University Extension. Thanks for being on the podcast. This is one of those areas we don't talk about very much. And I'm really glad that we did. And I think the work you guys are doing is fantastic.
And I hope that this model gets picked up in other states. We see it more widely applied because farming is important. And because farming is important, that means farmers are important. Just like you said, it's our asset. So thanks for being on podcast, Misty.

What does it mean to farm sustainably?
Sustainable farming is a collection of practices spanning from water and energy conservation, to soil health and biodiversity, and social equity.
Welcome to Marketing Tip Monday with SIP Certified. We know customers are looking for wines labeled as sustainable. While our longer-form episodes help you learn about the latest science and research for the wine industry, these twice-monthly micro podcasts will help you share your dedication to sustainable winegrowing so you can show your customers that you share their values.
There are so many examples of sustainability in action to point to right outside of your window:
Native landscaping: minimal irrigation and maintenance needs. Cover crops: promote soil health and provide refuge for beneficial insects. Alternative energy sources: reduce reliance on fossil fuels. Owl boxes & raptor perches: birds of prey feast on vertebrate pests.One topic that sustainable farmers get asked about often is pest management. In this Sustainable Story Marketing Tip, learn how Presquâile Vineyards utilizes technology to manage bird pests in a more environmentally and economically sustainable way.
Safely Keeping Birds at BayBirds like finches and starlings are common vineyard pests. They damage fruit and canopies, and will even create nests in the vines.
To protect their crops, vineyards typically use bird netting. While effective, netting comes with un-sustainable downsides: they break down in the sun, installation and removal necessitates a lot of labor, and they create waste over time, as nets must be replaced every few years.
Presquâile Vineyard knew there was a more sustainable way to handle their unwelcomed feathered visitors. In 2023, they installed five bird lasers.
Spooked by the beams of light, the birds stay away. But if the light beams repeat a consistent pattern, the birds will ignore the lasers and reenter the vineyard.
To maintain the perceived threat, the laser beams are programmed for a variety of motions.
As for the effectiveness of the lasers, Andrew Heilbrun, Vineyard Manager, says that âmonitoring bird pressure visually is pretty easy. We saw very little damage this past season after installing the lasers.â
On top of serving their main purpose as an effective method for bird abatement, Andrew notes that their new laser systems offer several other benefits:
Removes tripping hazard for employees. Doesnât affect non-target animals. Reduces waste. More financially sustainable.The bird lasers at Presquâile Vineyard have proven to be a Safe Pest Management strategy with benefits that touch all 3 P's of sustainability: People, Planet, and Prosperity.

To understand fungicide resistance in the vineyard, a group of United States scientists formed the Fungicide Resistance Assessment Mitigation and Extension (FRAME). Sarah Lowder, Assistant Professor and Viticulture Extension Specialist at the University of Georgia describes a nationwide sampling project to test for resistance markers. To get samples, they are promoting a new collection method called glove sampling. This process leverages the time that fieldworkers are in the field running their hands through the vines. They collect samples by rubbing their gloved hands on a cotton swab and sending the sample to the lab. Research shows that glove sampling results are very similar to spore trapping, a process that samples the air flowing through the vineyard.

Transcript2024-07-04_235_Sarah Lowder - glove sampling for mildew_Otter
[00:00:00] Craig Macmillan: Our guest today is Sarah Lawder. She is Viticulture Extension Specialist and an Assistant Professor in the Department of Horticulture at the University of Georgia. And today we're going to talk about some exciting new advancements around monitoring for powdery mildew and other related topics. Welcome to the podcast, Sarah.
[00:00:16] Sarah Lowder: Thank you very much, Craig. I'm very excited to be here.
[00:00:18] Craig Macmillan: First though, I want to start with something I just found out about that applies to this, and that is the grape frame networks. Can you tell us exactly what that is and kind of how it came about and what it does? Okay. Thanks, Craig.
[00:00:29] Sarah Lowder: Absolutely. Yeah, the FRAME Network is part of a USDA SCRI grant.
This is a project that was funded several years ago, I believe in 2017, as part of the Specialty Crop Research Initiative Project System. And FRAME Networks literally stands for Fungicide Resistance Assessment Mitigation and Extension. networks. And so this was a grant that was really intended to look and learn so much more about how fungicide resistance works in the vineyard for powdery mildew specifically.
But this was a group, a very large group of scientists from all across the country from a wide range of different disciplines looking into how we can better address fungicide resistance for vineyards and for powdery mildew specifically.
[00:01:12] Craig Macmillan: But there's also applications either now or in the future for other fungal diseases like downy mildew, et cetera.
[00:01:18] Sarah Lowder: Absolutely. Yep. They are currently working on getting a new iteration of this grant, Frame 2 as it were that will hopefully be able to address also resistance in Downy Mildew and Botrytis Bunch Rot.
[00:01:29] Craig Macmillan: Fantastic. This is really exciting because what I saw was that there are people at Washington State, Oregon State in California, and then on the East Coast.
So hopefully this work will continue. What exactly kinds of things does Frame do?
[00:01:45] Sarah Lowder: Yeah, so we had a multi pronged approach for this project. One of the big parts that I was a part of is looking at the assessment of the fungicide resistance. So one of the things that we did was collect powdery mildew from all across the country, from states and vineyards all over, all over the place, and then look for different fungicide resistance markers in that mildew.
That can hopefully help us much more quickly assess if we have fungicide resistance present in a sample. One of the big groups of fungicides that we looked at was the QOI fungicides, the Sturbulurins, also sometimes they're called or the FRAC Group 11, with FRAC is the Fungicide Resistance Action Committee.
Is what the FRAC group would be for that and those just kind of group your different fungicides based on the mode of action. So how they work on the different diseases that they're attempting to control. And so we were looking at this group, this group 11, the QOI products which operate by attaching to the mitochondria, so the powerhouse of the cell.
And just preventing them from being able to produce energy and so the, the spores die and you don't get any more growth of that disease. But because it's one of those products that works like a binding site if you get resistance presence it just means that your fungicide can no longer attached to the disease and then it can grow in the presence of that fungicide and then you can even no matter how much you spray that product it can still continue to grow.
By looking at there's one particular mutation that occurs that causes that resistance in this group of products and we're able to run a test much more quickly than you can otherwise do a lot of different fungicide resistance testing And tell whether or not you had QOI resistant or sensitive Mildew in your field so you knew whether or not you could use that product or not
[00:03:35] Craig Macmillan: What about frac group three?
That's another one that we have known Resistance issues with the demethylation inhibitors. Is that part of the project as well?
[00:03:43] Sarah Lowder: Absolutely Absolutely, the DMIs demethylation inhibitors, absolutely, the FRAC3 Group 3 are a group of products that have a little bit more complicated unfortunately of a resistance pattern rather than just having one particular mutation.
There, there are a bunch of different things going on in those products. But we do have a marker that can help us get a sense for the resistance. It's not as necessarily reliable as the QOI. Frack Group 11 product resistant testing, but we can test that as well and give us an idea of whether or not we might have resistance to DMIs present in the field as well.
[00:04:19] Craig Macmillan: Are there other frack groups that have potential or have found some resistant populations coming down the pike?
[00:04:28] Sarah Lowder: Absolutely. Anything that has a very specific mode of action really has some potential for having a resistance develop in a population.
[00:04:36] Craig Macmillan: Great.
[00:04:38] Sarah Lowder: We're, we're looking at some of the modes of action. We have not heard as much of field failures due to resistance to a lot of other products, but we wanted to, like, kind of get a, get a jump on looking for some of those other modes of action to see if we can develop. Test to be able to monitor that, monitor that much more quickly before resistance becomes as much of an issue.
And we were able to get a lot of that information for like the SDHI groups, which is the group 7 products. Although again, we're not really hearing too much yet of any field failures for powdery mildew control from the SDHIs. As well as looking much more into some of the mechanisms for how group 13, quinoxafen how well how the resistance might work in that system.
All of those are stuff that we were able to do because of the Frame Network project team.
[00:05:26] Craig Macmillan: That's really great. I hope that we can continue that. That's really important work. In order to do that kind of thing, you need to get samples. And you and your colleagues are promoting a new method for monitoring for powdery mildew and collecting, I guess, ASCA spores, I would imagine, is what you're collecting.
Tell me about it. There's videos on YouTube. It's really exciting.
[00:05:47] Sarah Lowder: Absolutely.
[00:05:47] Craig Macmillan: It involves a glove.
[00:05:49] Sarah Lowder: Indeed, we call them glove swabs, which is one of the projects that I was able to help lead as a part of the system. Because you hit the nail on the head when you are trying to monitor fungicide resistance.
The first step that you have to do is actually find the mildew. And you want to find this before you have a control problem. You want to find it while there's still not very much mildew present in the field. We looked at, we looked at a bunch of different ways. Not everything worked very well. But one of the ideas that we had was, oh, We have vineyard workers moving throughout the field all the time.
Could we potentially use these people who are already in the field doing normal stuff to also potentially collect powdery mildew? And we found that as you're moving through the vineyard, as you're moving your hands along the canopy, you're able to collect powdery mildew. Conidia spores, actually, it's generally, it's their summer spores.
are collecting and you're able to take a, just a cotton swab. So many of us have taken a COVID test that you've had to stick up your nose. It's a very similar, similar swab that you take with your hands. And you can stick that in a tube and send it to the lab for processing. This system worked, I think, way better than any of us were expecting it to.
It was actually much better than trying to go out there and look for it physically. And you can do it much faster because it's just literally, you can be walking through the vineyard with your hands in the canopy, take a swab. and collect it, and you can find that so much faster if you're already having to do a lab test for that product.
[00:07:16] Craig Macmillan: And also the potential here is that, let's say I've got a crew out and we're doing a shoot thinning in the spring, so they're handling the canopy all the time, we could swab some gloves and then send that out to be tested and get an idea what's out there.
[00:07:27] Sarah Lowder: Absolutely. Absolutely. And as you're already testing for whether the field is out there, you can also use the same test to tell whether or not you have resistant mildew to the QI fungicides.
[00:07:38] Craig Macmillan: Is this quantitative?
[00:07:41] Sarah Lowder: So, it is run on a quantitative quantitative PCR. So, in theory, it does give you some information on how much mildew is present. In the QI QPCR test, in the test that tests for the fungicide resistance pattern, it tests a piece of DNA in the mitochondria, and you can technically have different numbers of things.
Mitochondria per cell, individual cell, and so the, the quantitative, it does give you that information, but it's not necessarily the most reliable information. So as, as a scientist, I'm always hesitant to say that, oh, you can get quantitative information, but it, in theory, it does give you a little bit of information about how many spores at least you were able to collect.
You can tell a little bit of that information.
[00:08:21] Craig Macmillan: Can it tell me something along the lines of, I can go out and sample at the very beginning of the season, maybe even post bud break, and say, oh, we have nothing there yet, and then come by later and test and say, oh, we have something there now. Is there a qualitative aspect to it?
[00:08:41] Sarah Lowder: Absolutely. So we tested it and compared the glove swabs to visual scouting to compare it to someone actually physically going out and looking and found that the glove swabs were much more sensitive. They were able to find the powdered mildew much faster, and also much sooner than the OR than our visual eyes were able to do So.
But we also tested it in comparison to impaction spore traps. So these are tests that actually had come out of a lot of the lab that I worked in the foliar pathology lab with Walt Mahaffey at the USDA for a couple years previously with like Lindsay Thiessen that they were able to test these impaction spore traps which sample the air that flows through the vineyard.
We're collecting that many of the vineyards in the Willamette Valley of Oregon which we did a lot of the testing in that area as well as in Areas like Napa, California have a bunch of these spore traps present that we were able to test it in comparison to these spore traps, which have been used pretty widely in the system.
And what we found was that our glove swabs were showing us very similar information to these impaction spore traps which was really cool because a lot of these growers absolutely do use already these impaction spore traps to look at when they're going to initiate their fungicide spray programs.
So, in theory, yes. You could absolutely potentially use these glove swabs as a fungicide initiation indicator.
[00:10:01] Craig Macmillan: Yeah, that's what I was getting at, and that's, that's a really exciting technology. Because obviously we're trying to control the amount of material we put out there, and obviously part of resistance management is being careful what you put out and when.
And so having a good idea of what the timing should be, I think, is really important. And then of course, as everybody knows, People who listen to this podcast know, by the time you see it, it's too late, baby.
[00:10:24] Sarah Lowder: Absolutely.
[00:10:24] Craig Macmillan: You know, it's, it's, it's, you're chasing a ghost. And so, here's, here's our Ghostbuster tool, where we can catch that ghost before before it comes too much of a problem.
Now you said, send these off for, to a lab for analysis. What what labs are we talking about?
[00:10:39] Sarah Lowder: The initial frame grant project is technically at a, has come to an end and so the funding that originally funded a lot of this testing has ended, but now we're able to supply all of these protocols and testing materials and stuff to a lot of the different private labs elsewhere.
So I know one of the private labs that does the impaction trap testing. service in the William Valley of Oregon has taken over that process, as well as I know a bunch of different labs like I know at UGA here, where I am currently, they have some tools and able to do some of those testings or do some of those tests as well with the qPCR.
And so even if you, a lab where you send a lot of your materials, if they happen to have a qPCR present and you're strongly interested in doing it, you can talk to them to see if they might potentially be willing to add this into their repertoire.
[00:11:24] Craig Macmillan: So, this technology is starting to make it out into the world of commercial plant pathology.
[00:11:29] Sarah Lowder: Yes.
[00:11:30] Craig Macmillan: I may have a plant pathology lab that I already work with, I can talk to them, I can make some phone calls, and for instance, a commercial lab in Oregon, they're a business, so they still may do samples from California or from Washington or from Ohio.
[00:11:44] Sarah Lowder: Yeah, potentially.
[00:11:45] Craig Macmillan: It's not limited by territory.
[00:11:46] Sarah Lowder: Correct. You can send these samples and as long as you're not leaving your samples out in the sun and in the heat for a long period of time they can be shipped off elsewhere as well.
[00:11:55] Craig Macmillan: Where do you see this technology going? What's, what's the future here? We, we, we've just kind of touched on it a little bit, but what, in your, when you close your eyes and imagine the long term impact of your work, where do you see this kind of thing going?
[00:12:08] Sarah Lowder: One, I would love to see a lot of this information being used more regularly to be able to test this a little faster. And eventually, one day, we may be able to test for all of these different resistance genes, all of these different resistance patterns within the same sample. So you could be like, okay as a normal part of my practice, I'm going out and taking these glove swabs or whatever else that I'm looking to test.
Even if I don't use a glove swab, but I can come in and take my powdery mildew sample and send it off to the lab and get a, just a score sheet of exactly what fungicide products could be used or could be not used. That would be really awesome, because no one wants to buy a product that it's not going to work, and no one wants to put a product out that's not going to work for any reasons, environmentally or financially.
In the wallet or just for labor purposes. It's just a win, win, win situation. If you know, you don't have to use a product and instead you could choose a different one.
[00:13:01] Craig Macmillan: Oh, this might be a related, very practical matter. So gloves, touching vines, no problem. I can have workers. I could have actually my VIT tech go down a row and then swipe the canopy.
Where do I get the swabs because we're talking about something has to be a sterile protected swab, just like the COVID test swab. Where do I get those?
[00:13:17] Sarah Lowder: Yeah so a lot of the times, or at least for a lot of this test that we did originally they were groups that we sent out, or like just kits that we would send out to the different cooperating practices.
But essentially, it is literally the same tool. It's a polystyrene cotton swab tip and we normally will put them into these little half tubes that kind of keep their tip protected, and then you will stick it back into the plastic wrap that it came in, and then wrap it up so that it stays more protected. But it is, it is literally the same tool that you often will use for those COVID tests, which made it really hard to get that right at the beginning of the pandemic.
[00:13:54] Craig Macmillan: Where, where can I get them? Where can I order them from?
[00:13:56] Sarah Lowder: So I can send a link for the type of material that we're looking for. And then you can shop around for the same tip at a couple different locations and find the best price.
[00:14:06] Craig Macmillan: That'd be perfect. We'll put a link to that in the show notes. So folks, you can go check that out and find the materials that you need.
And then you can also shop around for the labs and see who's doing what. And again, if a lab is getting a lot of phone calls. That's going to encourage them to adopt this new technology. What is kind of the, the current state of the nation, if you will, in terms of fungicide resistance, what are the hot new topics, what's getting funded?
What are people working on and where are they working on it?
[00:14:33] Sarah Lowder: Fungicide resistance is certainly a hot topic that has a lot of different research happening in a lot of different areas. I could literally fill your entire podcast probably with talking about this topic. One thing that I'm very excited about is to hopefully see this Frame 2 iteration happen that is, being submitted for funding for this next funding cycle this year, but it is looking to hopefully also add in testing for downy mildew and betritis bunch rot, which are also two big diseases that can cause a lot of issues.
Especially now that I'm over here in Georgia, I'm very excited to hopefully get to test much more of the downy mildew which can be quite the struggle in the vineyard. And we're getting much more information on a lot of the other modes of action that we're working with. I'm excited to see a lot of the information come out about some of the quinoxephins.
Some of this information that we have started to work on and we haven't seen much field resistance to these products yet. But if we continue to use them, then they may still pop up. And so hopefully making sure that we can get ahead of the game for these other products.
[00:15:37] Craig Macmillan: I'm very happy about that because I'm old enough to remember when the DMIs came out and it was like, Oh my god, it's a secret.
It's the silver bullet. We're never gonna have to use sulfur again. Yay, and then it was literally within a couple of years they failed in some places. Now, the Fungicide Resistance Action Committee is publishing better information, more information, more accessible information every year about what's new about the different code groups.
And they're also now putting a category in, or they have for a long time, but they have a category in there about the potential for resistance. So they'll say, yeah, there's known resistant populations for this. This one has got high potential, even if we haven't found it yet. And that's directing research in that direction.
And I think that's really important that we stay ahead of these things. things, looking at where the potential is, as well as where there's known issues. So that's really fantastic. This is going on at what OSU, MSU, I think, Tim Miles in Michigan Walt Mahaffey in Oregon. I think Washington state.
[00:16:35] Sarah Lowder: Mm hmm. Michelle Moyer is the viticulture specialist at Washington state university, who's been the project director for this project, led with Walt Mahaffey, who is the foliar plant pathologist at the USDA located in Corvallis. the horticultural crops units. And then a whole, a whole group of scientists from across the nation.
There are people at UC Davis. There's people at Michigan State University. Even while I worked on this project in my role at Oregon State, I'm at with the USDA in Corvallis, Oregon. I'm now here at the University of Georgia working with Phil Brannon, who was the University of Georgia, Scientist working on this project and who actually was the person that convinced me to actually apply for the job that I currently now sit in.
[00:17:20] Craig Macmillan: That's great. You know, we do still have a little bit of time left. This is a huge topic, but I found it interesting as I was doing research on you and looking at your publications. One of the things you've been involved in is research on collective action. and information transfer among growers related to disease management.
And I am really fascinated by this topic. My background is in sociology. So my background is in people, talking to people, doing people stuff. And as we know, things, not just diseases, but also insects like mealybugs, etc. It's an area wide issue. And what you do or do not do on one farm affects what happens or doesn't happen on another farm.
Can you tell us just a little bit about what that research was like, what you did?
[00:17:57] Sarah Lowder: Absolutely. So that was really coming from how do we branch out from some of the fungicide resistance? Like how do we use a lot of this information that we are getting? One of the things that we were realizing is that some of the vineyards that we were working with, that we were getting some of these tests from, even organic vineyards who were not using any, they weren't using the QIs.
They also weren't using any other synthetic product. We're still seeing sometimes very high rates. of the fungicide resistance to these different products. And what we really found was that a lot of the information that we were able to look at was really so much more useful on that larger scale when we were able to look at all of this data in the aggregate.
And so one of the things, which I'm going to talk about my experience with the Oregon State, in the William Valley Vineyard growers especially, that they took all of this information, that they took the data, powdery mildew information that we are getting from their impaction spore traps. They were taking the fungicide resistance data that we were giving them, and they were sharing all this information with each other.
And we're able to say, Hey, oh, I was using this product, you know, on my field this year and next year. And then I started to see a lot of issues. You didn't see it immediately, but you saw it pretty closely after I did, even though you followed the patterns elsewhere. And so they were able to take a lot of that information and aggregate it and share together and be able to use that much more quickly.
I didn't talk too much about how much of the fungicide resistance that we were seeing. We definitely did see some differences in some of the states. that we were looking at, although it was generally pretty high rates of resistance to the QI products across the nation. That degree was less in a lot of the places in Oregon where a lot of this information started and where they shared a lot of this information from the get go.
So one of the things that we wanted to look at was how does this information come across and then what do people do with that information? Absolutely. So when you get into the area wide management, when you, when you start talking about it, you're like, okay, while I manage my property, Unfortunately, a lot of these diseases aren't just staying on my property.
If we could, if we could keep everyone isolated, then we wouldn't have to talk about a lot of this information management information management across all these different regions. What do we do once we have that knowledge and once we're sharing all of these spores back and forth even if we don't necessarily want to share that.
But if we can also share some of the information on what we're all seeing, we can all manage it a little better. Even if it's just as simple as like, Oh, my sprayer was not calibrated correctly and I'm starting to see More powdery mildew in my vineyard blocks. If you communicate that to your neighbor, then they may be able to increase their spray intervals a little bit more in order to not lose their crop because they're going to have to deal with a much higher crop load.
And they could be looking at the spore information. They could be looking at any of these monitoring effects that they're collecting. But if you can know that a source population nearby is going to be pushing more spores more readily, that's even before it's hitting your vineyard. So it's getting that information even a little faster than you would with some of the spore monitoring efforts, if that makes sense.
[00:21:01] Craig Macmillan: That does make sense. And so, in terms of the collecting the information, this doesn't just have to be glove swabs or, you know, impaction traps. This simply can be people saying, hey, I'm seeing mildew pressure that's pretty intense, or I'm seeing it earlier, or whatever. Other people are saying, I'm not seeing it yet, but I know I'm downwind of you, for instance.
Or, I know that my conditions are still very conducive, so I might be able to, like you said, increase my spray intervals, maybe check my calibration, check my coverage. It's a, it's a heads up. Basically from from one grower to another. How is this information shared?
[00:21:34] Sarah Lowder: So there are lots of different ways that this information is shared One of the ways that we wanted to look is at just what did people find the most useful when they were Looking for different information on either new diseases or old diseases or all that kind of thing And some of the stuff that we were finding was that people really found their colleagues, just those person to person conversations that they were having to be the most useful information when managing any diseases.
And while people certainly found, which I was happy to hear, that people found their viticulture specialists, their extension agents, to be extremely useful when helping to find this information, they really were still, the the most important part was their colleagues and their neighbors, the other growers in the area.
And so you can look at different ways that people communicate, which we, one of the things that we did was look at a communication network. So just exactly how is that information flowing in the system? And there are certain people, which this may not necessarily be a huge surprise. But there are certain people that a lot of people go to, to learn more information about stuff, especially as someone that is looking at a region and be like, Ooh, I have one, this super great new tool, mate, I have something even cooler than the glove swabs.
And now I need to tell. the growers about it. I need to see if we can actually use this in a commercial way that'll be viable. You can go to some of these more influential individuals within a region and then hopefully see that information spread a little bit more quickly than it might otherwise if you just kind of picked your people based on just where they were located or even just the closest ones you get your hands on.
As it were.
[00:23:09] Craig Macmillan: Gotta find the node. Gotta find the hub,
[00:23:11] Sarah Lowder: find the node. .
[00:23:14] Craig Macmillan: This is an interesting topic to me because one of the things that I think we've lost from a cultural standpoint is the coffee shop. People who are now retired growers have talked to me about how you're on your farm. You know, before sunup you get things running, you get going.
People are doing what they're doing. Everything's fine. And then you go to the coffee shop about nine o'clock and everybody's there. And that's where the information would get transferred. And this goes back to the, you know, basic farming decades ago. We don't do that anymore. What we do is we're there at Sunup before Sunup, we get things running, we get done, then we're back in the truck and we're on the phone and we're going to the next ranch and we're not connecting with people.
In that kind of social conversational way, the way that we used to. And so hopefully we can revive some of that either through meetings or through internet or through just simply networks, like you said, if there's a relationship, you can just simply call somebody and say, Hey, I'm starting to see this and hopefully we can build those social networks and see the collective benefits
[00:24:12] Sarah Lowder: and find more ways to bring us together.
[00:24:15] Craig Macmillan: Find more ways to bring us together in a world that seems to be forcing us apart, right? No. On this topic of managing diseases and monitoring diseases, is there one thing you'd recommend to our listeners around this?
[00:24:27] Sarah Lowder: There are lots of different diseases in lots of different ways that a lot of things are managed and we talked a little bit about Collective action in the sense that a lot of times some diseases are more effectively managed on a much wider scale than an individual Farming unit so like you could do the best practices in your own vineyard but if you have Someone next door doing lawn best practices that could just mitigate all of the hard work that you just put into it.
But it's hard to say anything on the large scale other than the fact that Talking more with those around you has a much wider benefit for disease management on all scales And just also grow better cultural practices, better more information on learning. I may be someone in the academia realm, but I always think that the more you can learn, the better.
And your neighbors are in the same game as you are, especially in vineyards. I feel like the mantra of the rising tide lifts all boats is very much in effect.
[00:25:24] Craig Macmillan: So we can learn from extension and from all that great stuff that's out there, but we can also learn from each other. Sarah, where can people find out more about you and your work?
[00:25:31] Sarah Lowder: Yeah, so now that I'm over here at the University of Georgia, where I'm most easy to find is through the Viticulture Extension website. It's called the UGA Viticulture Blog. We post a lot of information relevant to those growers in the southeast, but we also have a blog posting that sometimes will go out via email if you would like to sign up for that, backlog of what we've posted.
It's the easiest way to find me. I'm all around the University of Georgia system.
[00:26:00] Craig Macmillan: Fantastic. Thank you so much. Our guest today was Sarah Lowdre. She's a Denture and Viticulture Specialist and Assistant Professor in the Department of Horticulture at the University of Georgia. Thanks for being here. This was a great conversation.
[00:26:10] Sarah Lowder: Thank you, Greg. I had a great time.

TranscriptCraig Macmillan 0:00
Our guest today is Yu Jiang. He is an assistant professor of systems engineering and data analytics in the School of integrative plant science horticulture section at Cornell agritech. Thank you for being on the podcast
Yu Jiang 0:12
Thanks Craig for having me for these podcasts.
Craig Macmillan 0:15
I found out about you, because you're connected to the NASA acres Consortium, which is doing a bunch of really cool stuff for all kinds of crops around the world and winegrapes turning out to be part of it. What is what is NASA acres,
Yu Jiang 0:28
So I got to adopt the some of the official description about a NASA acre so our audience can better understand what's our mission and what's our approach. So NASA acres consortium is commissioned under NASA Applied Sciences program, and brings the value of Earth observation technology down to earth. NASA acres consortium established the march 2023 And then led by Dr. Alissa Witcraft from the University of Maryland. NASA acres is NASA's second consortium devoted to strengthening food security and agriculture, followed by the success of NASA harvest, a global focus a consortium but this time, NASA Acers specifically emphasizes on the US own agriculture land in NASA acres, we bridge the gap from space to farm and adaptation to impact to gather with US farmers, ranchers, and other agri food system decision makers who are charged with addressing the most pressing challenges to sustainable, productive, resilient agriculture now and in the future. to ensure our missions, NASA acres utilize a consortium structure to bring together a geographically, semantically and personally diverse group of agriculture actors, and partners from both public and private sectors collaborated within a model that matches ivory cultures own highly dynamic and diverse needs, and flexible partnerships and rapid actions on tools in NASA acres that will help ensure that a satellite based Earth Observations applications are user driven and free for all the preppers we envision .
Craig Macmillan 2:25
a huge mission. There's a bunch of different technologies that are involved here. And you're involved in a bunch of them. One that I'm particularly curious about was we had a guest on the podcast from Cornell Katie Gold, she was working with hyperspectral imaging and the detection of plant stress, but as a plant disease. And that's the that's the sky. Right? That's the information coming from satellites or whatever. You are the boots on the ground person. Is that right?
Yu Jiang 2:49
Yes, correct. I'm on the ground, I'm doing the groundwork.
Craig Macmillan 2:53
All right, we're literally grounding. So as far as that project goes, I understand that you're using robots and with sensors and artificial intelligence and whatnot to detect and predict disease spread. You tell me more about that.
Yu Jiang 3:09
For my account of a personal program, and the involvement of with NASA acres, you know, project, we bring in new, especially ground robots, we use various internet of of things, sensing network technologies, that we can offer the information as the ground truth matterments that many of these you know satellite or Earth observation data streams can use to try and various models for prediction, or estimation of various things of interest. And disease is definitely one of the biggest things for the ineyard management's currently adding in the future.
Craig Macmillan 3:50
Absolutely. If I understand what this work is on the ground as its ground truthing what the hyperspectral imaging is telling us is that right?
Yu Jiang 4:00
Roughly yes, if you can see there, all the current paradigm of doing remote sensing work. Most of the time, people are really focusing on the modeling, or how we can find the best and model to link or connect the hyperspectral signals collect data from, you know, satellite based or airborne based imagery systems, we use the ground truth data collected by a human on the ground. And these have been proven very successful in the past to produce various models that we are using right now including weather forecast, but with the very rapid and unprecedented climate challenges, and also the induced disease pressures. We are kind of lagging behind with the speed or pace we need to develop new models to tackle these problems. And that's a reason we want the robot to do so so that we can catch up with the disease. This can Have a fashion or progression speed, but also offer new tools for our viewers to use for their management decision making.
Craig Macmillan 5:08
So tell me about the robots, what are the robots doing?
Yu Jiang 5:12
So we developed a customized robot called the phytopathobot short for PPP. So basically phytopathology there's, my colleague, Katie Gold right is a scientist, that who really work on plant disease, and the bot is just the short name for the robots. And we put these two together, and basically just shows we integrated the kind of advantages offered robotic or automation systems with the new AI capability. So this robots can really bring the human experience and intelligence to all the fields that can do for example, if you see scouting recommendation, or some other, you know, checking functions that otherwise currently we have no human resources to do so for every single farm at the present time.
Craig Macmillan 6:06
Right? Is it fair to say that the training part would be described as artificial intelligence? Or should we call it neural network hearing? Or what would be the appropriate technical term for that part of it? Because I have a question about that.
Yu Jiang 6:17
Yeah, I think, broadly speaking, is a part of the artificial intelligence.
Craig Macmillan 6:23
Okay.
Yu Jiang 6:23
And that is more off the AI application for agriculture.
Craig Macmillan 6:28
What's happening is there's cameras then or there's some kind of a, either hyperspectral, or there's something that's getting information that's mounted on the robot, right?
Yu Jiang 6:40
Yes, correct. Our robot is currently equipped in ways both RGB multispectral thermal and the hyperspectral sensors, which many more on the road.
Craig Macmillan 6:52
And then you get readings. And then you know, human, I would assume says yes, this is disease, or yes, this is not. And then over many, many iterations, then the artificial intelligence learns what that is. And then it can be autonomous, you can send it out and it'll find it on its own, identify it on its own.
Yu Jiang 7:14
Yes, so I would see the autonomy is achieved at two levels. First is all the AI system for disease identification and quantification. We have a twin various models, with the expertise from our like, it's 30 plus year career technicians. And now we just a brand Hey, spray into the AI system that we can rely on to detect the disease in the field, specifically for a grape downey and powdery mildews at the moment. But at the same time, we also train the AI systems to guide the robots, autonomously navigating in the vineyard. is much more like the similar technology Tesla or other you know, EV car manufacturers are using for autonomous driving, but now just say, equipped those technologies with this ag robot that can do with autonomous navigation in vanguard in alternative in many of the different fields for agriculture purposes.
Craig Macmillan 8:14
the future of this technology, or the robots gonna continue to be a part of it, or are we going to be at a point where we're relying solely upon the aerial or orbit based imagery?
Yu Jiang 8:26
That's a great question. And I actually want to set up some of the context. information for our audience,
Craig Macmillan 8:33
please.
Yu Jiang 8:33
So yeah, the robots we kind of referred to here, actually those intelligent, you know, agent that can perform certain tasks in your backyard, or do the actual right to do all these operations, like a spring harvesting, you know, picking samples, all these, then when we consider how are we going to strategically and effectively deploy those robots? That's a big question is not a trivial because each robot at the current, you know, time would cost roughly 50,000 to $60,000. I think for many of the large farms, or wineries, the company will be able to afford that. For many of the small to medium sized farms, these can be a barrier for them to adopt the latest digital technology, which I hate, you know, that part as technologist. So one of the possibility is actually linked to the NASA acres project and the mission is a how we can use all sorts of information that can be affordably available to the growers to really use that for decision making. And a while of the concept we propose here is to make a closed loop joint training system that can connect the proximal sensing from the robots and other drone systems, we use the Earth observation data offered by federal agencies such as NASA, so that later all the growers can really enjoy, you know, using a very low cost or affordable platform offered from NASA or NASA acres consortia to make decisions on their individual farms. But largely training, the costs of a training such a model is taking over by large growers, largely, you know, stakeholders and some sort of a, you know, public and research institute that can balance the way or how the disadvantages you know, community can't adopt the latest technology.
Craig Macmillan 10:44
That is fascinating. You mentioned tasks, what kind of tasks are you talking about?
Yu Jiang 10:49
The current account of the PPP robots can do two tasks. First thing is for disease recognition, and the qualification, as I mentioned, for downey, and powerdy, and then now PPP can also generate a map right after the scanning off your vineyard, where those disease really severely infected your plants right now. And we working in progress try to use these PPP derive the map to correlate with the satellite maps or hyperspectral imaging so we can get so we can find which hyperspectral signals gone and correlated with diseases infection on the ground. And this is especially important for crops like grapes because of manual for the disease, or occurred from the bottom of the canopy, or the side of the canopy, where many off of the you know, satellite or Earth observation systems may not easily see at the beginning. But those signals will be embedded in the hyperspectral signatures.
Craig Macmillan 11:55
Got it. Okay. So I could get a map that would allow me to spray pesticide a fungicide very, very targeted way is kind of where we're going with this.
Yu Jiang 12:06
Yes, correct. I'm actually gonna just share some other ongoing effort here. Also, while also my colleague Dr. Devika Daughtrey from plants, Plant Pathology at Cornell agri tech, who identified the use of the UV, as treatment, powdery mildew or Downy Mildew for our grapes. And our account of ongoing efforts is to synchronize that map generated by PPP and the transfer to the UV robots. So now UV robots are gonna rely on that map to apply the UV treatment to balance the power usage and the hopefully to also maximize the contents of the disease spreading in the vineyard.
Craig Macmillan 12:52
That's really exciting. I understand the USDA also has some some role in this technology or related technologies.
Yu Jiang 12:59
Yeah, you ask the actually is a big partner of the whole team, especially for the grape genetics research unit, here in Geneva, New York. And we have a very multidisciplinary team, I will see I can see is from like a plant breeding to genetic to plant pathology now, including myself from engineering and robotics. And we also have about informatics, and we some colleagues from other universities on economy and marketing. So the whole team's efforts is back to a systems engineering approach, I would say. So when we look at the whole production, right, it's not just that, yeah, we have this robot that can do proceed and spray or deliver the UV treatment can solve all these questions. It's just hard to imagine that simple. So then we when we look at the whole agriculture production system, we started with the best plant material. And if we started with the building a candidate or a successful candidate data, usually just to make the rest of the whole production management much easier than ever before.
Craig Macmillan 14:14
Yeah, absolutely.
Yu Jiang 14:15
That's where, you know, all the scientists on the team really excited about how we can breed a new plant materials that have more like a natural resistance to plant the disease or maybe other stresses so that later on the in season management, it can be much more easily, you know, controlled or conducted by the growers. That Castile enable sustainable, you know, agriculture while maximizing the profitability for many of the growers in the future.
Craig Macmillan 14:45
I understand that one of the projects you've worked on had to do with phenotyping. So if I'm reading plants, there's a particular trait that I want and there's a particular expression of that trait that I want, whether it's disease tolerance or drought tolerance or salt tolerance. answer whatever it is, but that aspect of plant breeding is very difficult and takes a long time traditionally, and takes a high level of expertise. What is this idea of high throughput? phenotyping? What's that all about?
Yu Jiang 15:13
If you can have a think about the whole history of plant breeding, all the way you treat the back to mon Tao, we are human phenotyping is the best way, we just go to the field, plant and various plant materials, and just watch their performance in the field and find the best suitable for us. Right? So so then we recognize the traditional breeding, it becomes a numbers game, the more we test, the higher the possibility, we're going to find something, going t obe suitable for us, right? So we say it's a matter of who can email you this account of a traditional breeding way that requires the highest throughput phenotyping. Because the more you testing in the field, the higher the possibility we got to get something successful, and how to evaluate in the field is the biggest question right now. And that's where the high throughput plant phenotyping plays a vital role to address that bottleneck. So instead of for a breeder, to raw, only, you know, hundreds of 1000, you know, testing materials, the now can run, you know, 10,000, or even 100,000 in a year. That's how we hope to speed up the entire breeding cycles.
Craig Macmillan 16:25
So tell me the details of the tech of the details of the so I get some, I breed some plants, I've got some seeds, I'm gonna plant some seeds, right, I've got genetic recombination, now we gotta cross. How does this technology actually play a role? I put a bunch of plants in front of it, or how does it work?
Yu Jiang 16:46
Yep, so So in my understanding, there are actually two different paths ways to use that. One is along the traditional ways, as we just described, basically, we just find the best performancer from the field, right, and the system would just behave like a human in the field, we just find the tallest one, then we just a mirror the height of the plants in the field using the AI system with the robot, or if we want find more disease resistance is more like a what the PPB is helping right now, go to the field check a differente. And though gene all types off with a group of eyes, and then we find the least the infection as the candidate for the next one, right, this is a more like a traditional way. But now the second pathway is even more exciting is through the genetic studies. So once we kind of forget these phenotypes, especially there are differences, we have many different ways now can sequence them to understand their DNA markers and sequences, so that we will be able to work with the bell informaticians, to find which genes are associated with the phenotypic trees have a desire. Okay, so certain genes in my show, okay, the high disease resistance always associated with certain region in your DNA, and that's very likely being the gene or the region really control the resistance right to that particular disease. And if we ran multiple of these experiment, we get more and more as a candidate of Regents, and lead her on instead of keep running the field of trials, which still consume a lot of resources and the timing, because you need to wait until the plants are mature, and, you know, go through the entire season, we can now rely on those genetic, you know, information to identify the next around of a candidate, if the content of those gene regions is very likely, they're gonna have some, you know, resistance to certain disease. And that's another whole pathway, in my opinion, to facilitate the cultivar development in the future.
Craig Macmillan 18:58
And what is the role of AI in that?
Yu Jiang 19:00
So AI, please several rules there. So first, is to help the phenotyping itself, right. So basically, in the past, we sent a large group of it, you know, people go to the field and check the planet, hide diseases, infection, fruit size, you name it. And now we can just use, you know, robots to take images or even our cell phone to take an image. And then the AI will just mimic a human behavior to identify Oh, where the plant is, how tall the plant is, what's the number of leaves within that image or a number of a fruit fruit the size, a little versus, you know, trees and AI definitely now, at least, that being comparable with human performance for many of these tasks. And the other way is actually, to use AI as another tool to make a better prediction of relationship between the phenotypic trees and their genetic variants, right as we discuss for the second impassively is basically made to find that the association between genetic and phenotypic variants, and the AI also now plays a vital role to help us to find those relationships. It goes beyond traditional statistics human developed, and the find many interesting and hidden relationships that are currently statistic based approach cannot find.
Craig Macmillan 20:24
Wow, that's amazing. There's a couple of other things that that I that I was researching you that I noticed that were very, very, like practical right now, today, please, can I have some kind of technologies. One is improving the efficiency of pruning grapevines? And then I think I read this right, using facial recognition, AI technology to recognize powdery mildew infections. I would love to know about those two things, because those are two things that I would if I had it, I would use it today.
Yu Jiang 20:51
For sure. Let's start with the disease part. Yeah, cuz that's just allow what we just discussed why we developed that tool is basically a request actually, from my colleagues from the breeding and genetics slide. Okay. So in the past, my colleague, Dr. Lance Candle-Davison, at the USDA ARS develop a protocol that can use a one centimeter leaf disk as an assay to evaluate the disease progression, on the group leaf tissues, and then later on that can help him as a pathogen geneticists, to find the genes related to the disease resistance to powdery and downy mildews. But the challenge is, in the past, we have to train a bunch of, you know, technicians and the postdocs, even some of the other grad and graduate students at Cornell, to sit in front of a optical microscope and put the sample on our eight turn to like a tax 100x. And then manually identify how the pathogen really grew in the past a couple of days during the experiment, right, and then counted the number of a hyphal, which is a particular organ of the pathogen being grown, right. And then at the end of the day, they turn all these numbers back, and they will be able to run some quantitative genetic analysis, try to find the relationship. And I tried to once to be honest.
Craig Macmillan 22:27
Okay, yeah, I spent a lot of I spent a lot hours with a dissecting scope. So I hear you Isn't that fun?
Yu Jiang 22:34
Well, I want to see, for the first a couple of new samples. Yeah, it's it's a new experience for anyone, right? And if it's like, oh, yeah, I get that. After trial, you know, 10 samples. I'm done today. I don't want to see the front end of the microscope that day. And don't ask me to do this again. Right. It's quite tedious. And as a person, you'll feel fatigued very quickly. Yep. Very quickly, because you need to, to be super concentrated on what are you observing right now? And then also make the columns in your brain? I don't know how I did that. But I did. But after 10 samples, no, no more?
Craig Macmillan 23:16
Yeah. Yeah.
Yu Jiang 23:17
So that's the motivation for us to consider how the AI system can really help us, right? Because basically, what do we want the AI to do is giving you know, an image? Can you tell me? Which part content of the hypho And then tell me how I mean, how many of these hyphos are within that image? That's all right. So it's very much like the facial recognition technology we're using every single day. So our smartphone or maybe other security checking, you know, systems, right? And that just to give us motivation, hey, why not? Let me just build the robot and some of the AI tools that we can automate this whole process. So later on, instead of asking our students to do that very tedious work of observing the dissecting microscope, we will be able to allow them to do more intelligent work, how to find or improve the approval from the genetics, the perspective or the breeding perspective, rather than letting them doing this repeated and boring work. And that's the whole motivation here. And that's a reason why we can't have a proposed out method and that really got some success and to speed up that process. And now, just want to share with you in the past the year 2023 Last group, by using this technology was able to find a 60 more quantitative trait, a low sigh, which you can see there are data that gene regions related to certain, you know, phenotypic traits. And here in this study, that's more for the powdery mildew resistance. just named as single year, his team found 60 More as compare with, we fund probably 40 In the past four decades.
Craig Macmillan 25:08
Wow, wow, that's fantastic. There's so much here. There's so much stuff going on in it, as I have guests on that are working in these areas. It's just is it every day, I'm just learning so much new stuff, but I can't let you go without talking about pruning. I just, I just have to know about that I've I pruned a lot of grape vines personally, and I've trained people and you know, and there's, there's this, well, I'll just break it down for you. Pruning grape vines is an art form. And I don't care what kind of Trellis I don't care what kind of grape, whatever it is. And even if you're mechanized, that you gotta tune this thing up, and you got to collect data, and you got to figure out how this is gonna work. And when you have vines that are being pruned, you're trained, every single time somebody that I've been working with, usually above me was like, do these people really know what they're doing? Because they can't screw it up. Right? So now, is this going to help me? I mean, this is do you have technology? That's gonna help me you? I mean, I need this help.
Yu Jiang 26:02
Yes. Also, simple answer is A Yes, yes. And yes. So we are developing actually, the technology for the broader pruning a system for both apples and grapes as perennial crops, because they do need this type of technology to help based on my personal experience in the past three years, with both the pruning for apples and pruning for grapes, I share your burden Craig, it's not only you, but as an observer, and both the person who did the pruning, okay, using the knives, I have a strong feeling, I don't know what I'm doing.
Craig Macmillan 26:44
Right?
Yu Jiang 26:44
Right, I have a lot of criteria being you know, taught, say you need to find a branch that thick or that long, then you need to cut to certain lengths or just a cut them entirely, so that you can have new shoots coming with more healthy groups and the more productive grooves in the year. But to be honest, and once you get into the field, maybe perhaps the first several you keep that in mind. And then otherwise, oh, yeah, I just feel like these two needs to be cut. Don't ask me why I just feel that way. Right. And this is a kind of shows the non uniformity among the workforce. If I'm a beginner, I have less experience, I gotta be low in my working efficiency, I am going to create more problems, and rather than more success pruning, for the management, and obviously, the more counter for trend and people needs to be you know, pay them more because they have those experiences. So that all comes through the labor shortage issue, then it's just really hard to find those skilled people. So in my group, we kind of develop we are developing new 3d imaging technologies. Oh, wow. Yeah, that can get the very high fidelity of the 3d models of your grape vines and the apple trees in the field. And then once we get to some models, we can extract the skeleton is much more like how human described that, oh, yeah, that's my skin, and then I have to shoes and how they grow. And then we just be able to do that in a granular detail with all the needed information, like what's the diameter, or what's the length for each of these branch. And then due to all we can, based on our predefined the pruning criteria, to decide where are the cutting points, so that either a person or maybe a machine, or maybe a robot in the future, can go to the field directly cut based on the information we already get. Yeah, and the good thing is now with this whole kind of a new approach, instead of based on our existing you know, criteria, we can also form all different sets of criteria to really prune it in whatever way we want because that's a digital system. It won't hurt anything rather than using some of the power from you right? And then we can count off a get a difference you though proven the vineyard to take a look which we better serve our purpose. And we are also working with some offer collaborators try to incorporate to the growth models for grape vine. Try to see with different pruning strategy how the group vine or apple trees gonna grow during the growing season. And how I mean for me differently you know, branch structures and maybe different fruits load and the distribution with a hope you know, if we know this information beforehand, we can let the universe to determine what might be the best strategy we want to do as the you Though time progress to the green season, so do you have much more information in advance? Rather than Oh, yeah, I got it just to do the pruning. But that's the best I can do.
Craig Macmillan 27:15
Right? Right, right. So it sounds like that could be kind of an iterative process, you have a robot go through, and you get your 3d model, and you bring it back. And then you develop an algorithm essentially, that says, Keep this, don't keep this keep this, don't keep this, cut it here, cut it there, then you could execute that. Exactly, basically, to the vine.
Yu Jiang 30:29
Yes. Correct.
Craig Macmillan 30:30
And then you could have it grow. And then you can come back the following year, and say, Okay, well, what happened? And you could refine that model over time.
Yu Jiang 30:39
Yes, correct. That that's exactly the concept called a digital twin. Wow. Yeah, we see is a product actually from NASA, used to use that for you know, making the Mars rovers or the moon rovers, because they need to simulate so many different things before they put the actual manufacturing, right. But now we want to adopt these concepts for agriculture, before we do any of the decision making on pruning or harvesting. We want to see how they progress in the digital world, because it just takes us so minimal cost, and then we can have better understanding which way might be the best, we want to move forward.
Craig Macmillan 31:20
Wow, that's really exciting stuff. This technology is probably still in its infancy, I would guess.
Yu Jiang 31:27
Yes. Correct. I mean, although now we have more and more 3d imaging technologies and even more like a loose AI driven approaches. But it still is early stage, we are having some challenges from the field. So that's a reason we are, working hard to make progress. And I hope to share more things, you know, in the coming years with the audience here and hopefully demonstrated to the grape industry someday.
Craig Macmillan 31:53
Yeah, absolutely. Keep going. We're out of time. But I want to what is it one thing you would recommend to grape growers around this kind of topic, these topics, I guess I should say,
Yu Jiang 32:05
Can I share two actually?
Craig Macmillan 32:07
Please yeah, to is great.
Yu Jiang 32:09
Why I really want to share with with all the growers as we are at the point where many of these digital technologies are being more and more available and affordable. So please keep your eyes and the for example, at Cornell, my extension program focuses on the digital agriculture trials for adoption short for data aims to fill in the gap between you know, the growers and the startup companies who deliver those new da tools for production management, and also tried to offer more knowledge base to our growers, they can learn and better use these tools by themselves. So this is very important, as many of these tools go and just a calming and you don't want to miss the opportunity offer using the best of the tool to shop yourself and make better management. The second thing I also really want to share with our audience here is pleased to share all these exciting lands from digital agriculture to our case, to younger generations who are working in your, you know, vineyard or winery. I'm a strong believer the best investment is always you know, for the future generations. If they got excited if the et buy in all these ideas and put more efforts to start, you know, learn and develop new technologies back to agriculture and the food sectors. I believe we're gonna have a sustainable and resilient agriculture in the future for sure.
Craig Macmillan 33:39
That is fantastic. Where can people find out more about you.
Yu Jiang 33:42
you can check on my labs website is a se a i r dot c a l s dot cornell.edu. I will provide you the link so that you can share with the audience.
Craig Macmillan 33:58
Fantastic. So our guest today with Yun Jiang. He's a system professor of systems engineering and data analytics in the School of integrative plant science the whole crypto section of Cornell agritech thank you so much for being on the podcast. This was really fun.
Yu Jiang 34:13
Thanks so much Craig for having me today and as my priority to share our ongoing efforts and research with the broader audience here for grapes. Thanks, everyone.

âFood disconnectâ is a term used to describe the average consumerâs lack of knowledge about where their food comes from and how itâs made. When it comes to wine, most consumers only see the finished product in the grocery store or tasting room!
Welcome to Marketing Tip Monday with SIP Certified. We know customers are looking for wines labeled as sustainable. While our longer-form episodes help you learn about the latest science and research for the wine industry, these twice-monthly micro podcasts will help you share your dedication to sustainable winegrowing so you can show your customers that you share their values.
While everyday agricultural practices may feel ordinary to you, these topics are fascinating to the average consumer, who likely has little to no insight into the block to bottle process behind their glass of wine.
Describing specific practices and why they are important helps customers understand the time and care that went into producing their wine. Sharing your unique story welcomes them to take part in the good feelings that come from supporting a business that is doing better for the people and the planet.
People care about social and environmental issues, and want to support brands that share their values and do something about it.
This weekâs Marketing Tip tells the inspiring Sustainable Story of how Bien Nacido Vineyardsâ irrigation team demonstrates diligent Water Management through the use of technology and a growth mindset.
Data-Driven IrrigationWater is a valuable resource for all forms of life. But it is limited and must be used responsibly.
Bien Nacido Vineyardsâ team of experienced irrigators, led by Miguel Asuncion, take several steps to ensure efficient water use.
To avoid system malfunction and uneven hydration, vineyard stewards must constantly maintain their systems. Bien Nacidoâs team performs multiple line flushes each year to keep them clear of dirt and debris, and routinely tests distribution uniformity to ensure consistent hydration across their diverse terrains and elevations.
Vines arenât heavy water users, and Mother Nature provides a portion of what they do need. Bien Nacidoâs irrigators track rainfall, weather data, and soil moisture levels, and estimate evapotranspiration. With this data, they tailor their irrigation schedule based on the landâs needs.
When their data shows their vines need water, the team of irrigators waits until the sun is down. They irrigate during dark hours because without the sunâs heat, the vines and soil can more efficiently absorb and utilize what is applied.
But they believe opportunities for enhancement never end. Bien Nacido partners with experts to help identify even more areas for improvement.
They have created a plan to advance their soil and sap flow monitoring technologies, and seek further optimization opportunities with regular analyses of their irrigation systemâs design, filtration, and pressure regulation.

Lange Twins has implemented individual regenerative practices but now they are asking, what would happen if they stacked them? Kendra Altnow, Sustainability Manager at Lange Twins Family Winery & Vineyards and a 5th generation Lange shares Project Terra. The goals are to increase biodiversity, build and enrich the soil and improve watershed through shifting farming practices, restoration and conservation. They are accomplishing this through grazing livestock, establishing permeant ground cover, reducing tillage, improving native habitat, and reducing reliance on herbicides, insecticides, and fungicides.

Our guest today is Kendra Altnow she is sustainability manager at Lange Twins family winery and vineyards and she's a fifth generation. Lange. Welcome to the program.
Kendra Altnow 0:09
Thanks for having me. Glad to be here.
Craig Macmillan 0:11
We want to have you on because you folks there at length twins have been doing some really innovative things around regenerative agriculture. And through a project you're calling project Tara, what is project Tara? What's that all about?
Kendra Altnow 0:25
Well, we kind of have two different definitions, I would say a project Terra one is the concise purpose of project Terra is to increase biodiversity building, enrich the soil and improve our watershed through shifting our farming principles and practices, restoration and conservation, all while building the next generation of land stewards. That's what I like to say is the on paper definition of project Terra. But project Terra means something a little bit different to me, it's our vision coming to life. Like many of us, the health of the planet is a top of mind. And a few years ago, I really wanted to see what we could do as a family to contribute to being part of the very complex solution equally as important passing our land to the next generation healthier than it was passed to us. So I really just started reading and I learned that there are lots of changes that we can make. But we have a unique access to something that a lot of other people don't have. And that's our land. And really, I see that our land gives us the greatest opportunity for change. So we started just digging into what those practices look like. And regenerative farming really was something interesting and something very obtainable for us to do.
Craig Macmillan 1:41
What are some of those practices? Because from what I understand from doing research with what you're up to you, you did certain things 10 years ago, and then you brought in some other elements, and then you tried some other elements. Now you're kind of trying to bring them all together, if I understand correctly, what are some of those elements?
Kendra Altnow 1:55
Yeah, that's exactly what it is. I like to say when people come out and come to the farm for tour, that we've been practicing everything in different vineyards, but not necessarily taking those practicing and what regenerative agriculture calls stacking them. So the components of those are reduction of off farm inputs, livestock integration, maintaining permanent ground cover, conservation or reduction in tillage, creation of habitat, which is one of my favorites, and reducing our reliance on herbicides, fungicides and insecticides. So those were all practices that we have been doing. But we said, hey, can we take those and put them together in one pilot vineyard. And that's really the core of what Project Terra is. And for us, it's not just about doing it on that pilot vineyard, but is building the framework to be able to scale it to the other vineyards within our families holdings.
Craig Macmillan 2:56
You mentioned you were excited about this particular area. And I think it's an interesting one, too. And that's habitat.
Kendra Altnow 3:00
Yes, that's my wheelhouse. I love it.
Craig Macmillan 3:02
Yeah. So tell me about that. How does that play into this project?
Kendra Altnow 3:05
Gosh, it's a huge portion. Biodiversity is really a big element of what we need to do here as farmers in general. When my grandfather was farming, he did edge to edge farming. And that really is you didn't see anything green in those vineyards whatsoever. When my dad and uncle came back in 1974, the ranch that they grew up on really looked different the wildlife that they had enjoyed seen. It wasn't there anymore. But the reason why it wasn't there was because the habitat was gone. Without that biodiversity, there was a shift in the ecosystem. And so with that, is this new recognition that we're approaching ag at that system's level, where we're seeing the farm, not just between the rows or from edge to edge, but everything inclusive.
Craig Macmillan 3:52
So how do you do that? If you like, did you take landlords in production? And then set it aside for habitat? Or did you identify areas that could be habitat and then restored them in some fashion? How did you how did you approach that?
Kendra Altnow 4:05
Yeah, and that's, you know, something we've been doing for a long time is habitat restoration, primarily riparian restoration, our family is here on the Mokelumne river. So that's our watershed, and we have unfarmable areas. But we also have areas that were planted that we have taken out of production just because the quality coming off the vineyard wasn't meeting the standards of the winery. So we we kind of have a multiple approach. Over the years, it was just what we could get done. Recently, we worked with point blue conservation science and we have a conservation plan. And that conservation plan takes a look at all of our land that we farm as a whole and has helped us identify areas where we can make improvements that's not only within the vineyards itself by creating maybe filter strips or wildlife corridors, but also where We have maybe a vernal pool area, and what we can do there. So really enhance what is already happening. So it's a little bit of everything I guess is we've, we've had help. But we also just noticed, oh, that area over there isn't great. Let's put a pollinator habitat in.
Craig Macmillan 5:16
And you've been doing as long as you believe that there is some improvements and some stability from increasing the biodiversity on the land.
Kendra Altnow 5:24
Let me take a step back. Biodiversity has definitely increased here on our farm, just the other day, we saw two Bob Cats hanging out on the bridge by our house, that is nothing I saw in my childhood. So I can definitely tell you that there has been a shift because there are animals and birds that we haven't seen that are coming back to our area, those animals and birds are what we see. And so can you imagine what we can't see? So what we're making the impact on? Who knows, right? I don't I'm not out there every day with a microscope looking. But by these bigger animals being here, I have to say that the other ones are here, too.
Craig Macmillan 6:04
And do you think that leads to a more stable? agro ecosystem?
Kendra Altnow 6:08
Absolutely. 100%
Craig Macmillan 6:10
100%, you had mentioned also things around fungicide, insecticide herbicide reduction. How does that play into what kind of practices and how does that play into the stability of the project overall?
Kendra Altnow 6:20
we just finished reading a book. And there's a lot to be said about soil health, right. And that's a big topic, especially in ag these days, I think that we're a lot better than we have been. That's what sustainability is all about, right? Is continuous improvement, really digging into the health of the soil makes us recognize that maybe there's more we can do. From my perspective, having biodiversity above ground and below ground is only going to help us not just in our vineyard and the production of the wine grapes, but also as a whole for everything around it. I'm not sure if that answered your question. Sometimes my brain goes off in tangents.
Craig Macmillan 6:57
No, I think I think it's the right idea, I think what you're getting at is by looking at things as being integrated, looking at from a system standpoint, where everything affects everything else changes that make over here, make changes over here. And those can be beneficial changes, they don't have to be negative changes, necessarily.
Kendra Altnow 7:12
And I think also, it's such a long term result, right. So it takes a very long time, for us to see the true benefits of what we're doing today. I always say, Gosh, I wish we would have started this, you know, 10 years ago, because then I would feel better about what we're doing. Now you have to have patience. And I think that's been the biggest learning for us or for myself in particular, is that you're not going to change your soil structure or your soil health or anything that has to do with the environment, it takes time. And it takes that dedication. And it's not always the easiest path forward either. So you really have to sit back and realize following that vineyard, for a certain period of time might seem against what we would typically do. But in the long run, it's going to benefit what we're doing, if you understand what I'm saying,
Craig Macmillan 8:09
Yeah, I do I do I change this to soil health improvements. And so structured water holding capacity and things like that. Those do take a long, long, long, long time. But you have to do it if you're gonna get there, you know, and I think what a lot of folks are finding out from the interviews that I'm doing, you know, you may go like, Oh, my God, you know, it's gonna take 10 years, well, 10 years can fly by in terms of like a region, you know, just do it stick to it part of that cover cropping. So you folks have been doing cover cropping for a long time. And I'm guessing that the decisions that you've made in terms of what to plant, where to plant it, maybe even how to plant it, how to terminate it, and probably evolved over time. Can you tell me a little bit about your cover cropping, philosophy management, how that's changed over time?
Kendra Altnow 8:51
So my very simple philosophy is the soil is better served covered period, I believe that not only in our own homes, at home, in our backyards, and our front yards, but also within the vineyard. So that's an aside from how we make our decisions on what cover crops we plant. When it comes to cover crops. I'm sure you know this, they're super complex, there's so many different species out there. And they all are very specific on what you're trying to do for typically the health of your of your land or your soil. So what we always look at first, is the vigor of the vine because we want to ensure that we're not taking away from the growth of the vine and then regional erosion. So those would be like the two starting points for us. And then from there, we combined with the soil type, if we're going to be grazing or not grazing and then the ecological benefits so it's kind of a stacking just in decision making. And then the way we choose what vineyards it goes into, we we across the board, try to get it out. Timing is a big thing for us in all of our Lange Twins family vineyards, except in the vineyards that the mower can't fit down the rows. So it's a very operational decision on that, that side.
Craig Macmillan 10:10
What are some of the variables that you've been trying to manipulate? And what were some of the plant choices that you made to achieve those goals?
Kendra Altnow 10:19
Erosion control is probably our biggest number one cover crop choice that we do or a multiplex this species type, that's something that I would have to ask Chris and Charlie, or even Maria, on our team, they handled the decisions of that. But I'm involved in more of why. So I'm sitting here looking out my window at one of our vineyards, and we have a runoff issue. And so we made, you know, a very spot decision to plant a an erosion control mix, just because it's not planted right now. And we saw two years ago, or, actually, it wasn't two years ago was last winter, it was just gosh, the amount of soil going into the soil was absurd. So what can we do about it? So a lot of it is knowing your land as well, and making the decisions that way?
Craig Macmillan 11:07
So you're using different things in different places. So for some areas, it's all about erosion. Other places, it's about probably water management,
Kendra Altnow 11:14
Or, you know, your nitrogen fixing is a big decision making as well, depending on the vineyards.
Craig Macmillan 11:22
Oh,that reminds me, so I hadn't thought of before, have you been doing any, like pre post testing or control treatment kind of testing, as you do these things
Kendra Altnow 11:30
For cover crops?
Craig Macmillan 11:32
For cover crops or anything else.
Kendra Altnow 11:34
We do a lot. I mean, we do a lot of soil testing, is what we've started doing. And we do that not only just from a short term reason of seeing what's happening right now. But in these areas where we are doing no sustainable ag versus regenerative AG, we have started long term analysis so we can see what really is going to be happening in the vineyard long term with the decisions that we're making today. And does it make sense. So does it make sense for us to do it? Well, maybe it's not making a huge impact on that level, but it will be financially. So there are a lot of tracking that we are doing, because we need to make sure that it makes sense from a sustainability point of view.
Craig Macmillan 12:21
What do you been finding out?
Kendra Altnow 12:22
That's a great question. I It depends. I mean, it really depends on where, and it also depends on what and that's what's so tricky about farming. There isn't a playbook. Right. So what is working on one vineyard isn't necessarily working on another, for example, we have a vermicompost trial going on right now. And it's interesting, we've set it up. And we've done all of the analysis. And what we found is that different phases of the growth of the vineyard, the vermicompost, made a difference. But at the end of the growing season, everything caught up. So it's going to be interesting to see this year, what happens because is there going to be a true difference year after year. And then we'll add in do we add vermicompost again, so what we're trialing right now, which is really fun, is taking our pumice from the winery and feeding it to red worms to see if we can then reapply it out in the vineyards. What we don't know about that is if what is in the vermicompost by the worms, eating our promise is something that is going to benefit the vineyard. So benefit is in the sense of we're closing the loop on our promise, but it may not actually have any value to the soil in the vines themselves over a traditional form of compost feeding. Worms are really fun.
Craig Macmillan 13:45
I'm just gonna ask about that. So you're making worm compost on site?
Kendra Altnow 13:48
No, we're not. So there's a neighbor of ours, my cousin in law found I went out to visit him and I asked him if he would be interested in trial doing a trial with us. And he said, Sure, so we're taking pumice over to him from the winery during crush, and then he is running the trial for us. If it is something that becomes viable for us to do then we would transition it and start it on our own.
Craig Macmillan 14:15
Which reminds me of something else. You are working with a number of collaborators, you're not doing this in a vacuum and we'll transition into grazing was part of that but like what are some of the collaborators here you have your your neighbor, you're obviously working with probably other agencies or other other companies or their specialists who was part of the team here outside of Lange Twins.
Kendra Altnow 14:36
Oh, so many when I started in this role, going back a little bit is I you know, I didn't go to school for farming or winemaking and or sustainability for that matter. And so I took a lot of learning, calling and asking questions. Honestly, some of the organizations I reached out to first I was Point blue conservation science I hopped on, you know, the internet and I started just Googling people and seeing who would be interested in coming out and giving me a hand, they have been awesome because they really have introduced me not only to a whole host of other individuals within the that side of the world. So I would say the habitat side of the world, they did our holistic conservation plan for us. That really is what I would say is my strategic plan on that side of my role. From there, I work with the Center for land based learning their SLEWS program, in particular, the kids from that program come out, and they actually implement some of our projects for us. And that's great, because that really is helping that next generation of land stewards in my mind, hopefully, some of them will come back and want to do this and do it in a fashion that is smart for both themselves and for the environment. NRCS Of course, Xerces, East Bay Mud, calf Valley grazing, hedgerow farms, Megan Phillips, Kelly Melville, you name it, I have like talked to all of them. And really, they have all been instrumental in us putting this together and moving it forward.
Craig Macmillan 16:22
I think it's an excellent transition into grazing.
Kendra Altnow 16:26
Yes, that's fine. I love graze
Craig Macmillan 16:28
you love it. Okay, cool. Well, here we go. If I understood correctly, from some things that I read, you folks are looking at moving into year round grazing. Can you tell me a little bit about the evolution, how it started, how you kind of got into it and how you got to where you're at now and kind of where you see yourself going in the future? Because it sounds like you actually are moving you're not done yet is what it kind of sounds like to me if I understood.
Kendra Altnow 16:51
We're just getting started. Grazing came to us through Charlie's sStar, there were sheep grazing and alfalfa field next to his home vineyard. And he offered the grazer to come into his vineyard for feed. And he said, guys, they did a great job. What do you think? And so we trialed it on 100 acres, and it was great. They came in, they did their job, it was the winter pass, and good to go. We loved what they did. We learned a little bit. And then the following year, it was ramped up big time. So we had a contract raiser come in. And we had probably 2000 to 3000 sheep everywhere, literally everywhere. And that winter was really raining. So it was difficult to get them into the vineyard. Some of them were flooded out. And it was just a challenge all around. And then when the rubber hit the road in the springtime, they got a better contract and left. So we didn't necessarily truth be told, have the best experience the second year. And it was logistically the main reason why. So the third year, we wanted to approach it a little differently. And I was at a young farmers and ranchers dinner and was approached and said, Hey, I had know someone that would love to do vineyard grazing. So great. So we sat down and talked. And what we realized is that what was going to work best for us is for them to be a true extension of our team. So not someone that's just going to come in and then move on to someone else, but someone that is going to be dedicated to working with us, because that is what we found was most important is that we're working together. So I see Valley grazing and Ross Mulrooney as not a separate from length twins, but he is part of length twins in the sense of being our sheep herder, right. So he's the guy, the boots on the ground, moving the sheep, the health of the sheep. And we're just helping direct them in that. And that honestly, if I could give anyone advice, and I know this can't happen for everyone based on size, or lots of other complexities, that has been a saving grace for us, because it's just, he, he knows what we're working towards. And we know what his needs are as well.
Craig Macmillan 19:14
You're working collaboratively. He has needs the sheep have needs you have needs can we find a way to have those things meet that makes a better outcome leads to a better outcome. Without question, yes, it sounds like you started with kind of the traditional, hey, let's get some animals, let's turn them loose. They're gonna go run around and do their thing. Oh, they're done. Now they leave. My experience with grazing is that it can get much more complex than that, and can lead to some even better outcomes when the management becomes a little bit more intensive, which it sounds like you're kind of moving towards is that right?
Kendra Altnow 19:52
Right. I mean for us, our goal is to have four passes a year with the sheep so it's It's a tool for sure. That's how we see this. It's a practice that we're going to implement within the vineyard. That's no different than mowing or herbicide spray, for example. So for us, the number one reason why we started it, there's lots of factors but was for that biodiversity in the soil and the soil microbiome, we know that animals do make a difference. So that was a really big factor. The second factor is back to the herbicides, if we can cut down on that, that's also going to help that soil microbiome third is the fossil fuels. Right. So by employing the sheep in the vineyards and integrating them in, we are cutting on fossil fuel use by all of the tractor passes that we're not doing anymore, etc. Sure, at first, it was like, Yay, winter weed control. This is awesome. But then you start scratching your head and peeling back the layers, you recognize that there's lots of other benefits of having animal integration. I mean, I sometimes they were just going back before my grandfather, right? They had animal integration, they actually had dual crops within their vineyards. And so it's like, we're going back to what we knew our ancestors. And we're applying it today, but in a modern way, with changes, of course, because we're not homesteaders.
Craig Macmillan 21:27
So we're talking, you said four passes. So what, what's the timing? What's the timing of the other grazing passes.
Kendra Altnow 21:34
So the first grazing pass for us starts post harvest. So three weeks after the vineyard has been harvested, we can move in the sheep. And really, this is to clean up weeds, vegetative debris, and the leaves. The second pass is the cover crop and weed management on our rotation. Typically, what ends up happening is why when they're done with the first pass, they're going to go start kind of all over again, right. And so now they're going to the cover crop and weed management. And that is what really this time of the year is. So they're out there mowing the cover crop, or they're really happy sheep, because they have tons of feed and getting the berms, we always focus on the berms. That's really important for us, especially if we're if we're not using any herbicides, it's really important for us to pay attention to the berms. The third pass is cover crop and weed management again, and this is kind of when we have the blind canopy management happening suckering chute hygiene and leaf removal. So it's in that spring where springtime, where there they can get in, they're not going to do a lot of damage, and they're still going to do good. And then the last pass is summer, so forth passes time or weed control. We are using these only and our trellis systems that are high wire. And so the Sheep can't really do that damage, because they can't reach up into the canopy and make a huge impact.
Craig Macmillan 22:57
And that was something that I mean, you you folks may have some experience with this. Maybe too early still, you know, the trend has been towards shorter and shorter, lower, lower trellising for a long time. And it's always been Oh, wine quality is better when the trellis is lower. And then we have these systems here where you will Yeah, but if I train a little bit higher, a little these other benefits that I can get is your winemaking staff getting feedback at this point. Are you seeing anything in terms of the cultural differences between the more traditional trellis and a higher wire trellis.
Kendra Altnow 23:26
I can give you a very specific example. We have single vineyard wines. And on our single vineyard wines, they keep all the lots separate. And we have an older cab vineyard. And then we have a high wire cab vineyard that is a little bit younger. The older one is California sprawl, it was planted in Gosh 1980s. It's our winemakers favorite vineyard. And along comes our River Ranch vineyard. And it's high wire and it is mechanically pruned and it is grazed and very different than what they 38 is. And I'll tell you what, they love that River Ranch cap and made it as a single vineyard wine. And so that to me goes to show that it can work both ways.
Craig Macmillan 24:09
It can work both ways. This is so fascinating. We could just go on forever. But is there one thing regarding kind of your experiences with all of this, all of this integrative stuff, is there one thing that you tell our listeners that you would recommend to them? As far as this goes this area?
Kendra Altnow 24:25
Oh man, I have so many recommendations. That could be like a whole thing on its own.
Craig Macmillan 24:32
You're gonna write a book?
Kendra Altnow 24:34
Probably. So my one recommendation is every little bit helps. And I truly believe that and that is something that you can do not only within your vineyard or your business, but you can do that at home. So my passion came from my family, because we have been farming sustainably in a really big way. However, my practices at home for example, I really got ignited because I saw a picture of all the plastic in the ocean and I had a heart attack. And I knew at that point, I couldn't use plastic bags anymore, for example. And that's a true story. I think that even though everyone around me might not have changed that practice, I know that that little bit does help. Right. So I think that is really important. I think the other important thing, when you're talking about farming, is the mindset shift. Farmers have been farming and doing things the same way for years and years and years. And it really takes forward thinking or openness to be able to change the way you're doing something. Because it's harder, it's harder, not only to train your team, that it's going to be done differently. But now you're using another tool, or introducing something different that hasn't been done before. So there's a learning curve. And when you have 100 million things going on, that one new thing feels like 100 billion pounds. And I think that it's really important that you have a cheerleader, which that's what I am, is the cheerleader to say, Hey, I think that this is really interesting. Do you think that we can implement not all of it at once, but do you think we can handle parts of it. And even that one small step is going to get us to where we want to go. And I would come in very different from, say, Erin and Phillip, my brother and cousin, they've been entrenched in farming for years, I kind of have this outsider's perspective where I don't necessarily know all of the logistical nightmare that might happen. Or I don't know all of the little idiosyncrasies that happen. All I see is this awesome opportunity. And then they bring me back to reality. And then we meet in the middle, and then we implement something. But I think if it was someone that didn't have that, like, I think we could do this, it wouldn't come to the forefront, because we're just so tasked on what we're already doing, and making sure that we're getting it done, that doesn't really give us time to do anything different. And I think that to me, has been the biggest learning. And maybe that the tidbit that I could give others is that be be that cheerleader or somehow find yourself to be that cheerleader for yourself, because it really will make a difference.
Craig Macmillan 27:41
I think that's great. I mean, every every little bit counts and being a cheerleader. Yeah. Sharing your excitement and your successes. I think it's huge.
Kendra Altnow 27:50
Yeah, I mean, it's, it's funny, Craig, between you and I, or if you want to put this out there I you know, I don't have a science background. I don't have a farming background. I don't have anything like that type of background. My background is sociology. And for for me, I just know that we can do better. And we have an opportunity to make positive change. And so I come in with they always call me rainbows and sunshine. Because that's that's like, really, for me, that's what it's about right is, is how can we make a difference, and I dried down I5. And I'm like holy smokes, we are the size of a gnat when it comes to farming in this world. And how to like I sit there and think, wow, I am I'm working hard to make change on my tiny little farm. Just think if we could get this farmer who has 30,000 acres to also make that change. And I think that's where it's at is it's got to start. I see. I mean, we're not small in the sense of tiny, tiny. We're midsize but gosh, there's some big farmers out there. And so sometimes it's like, Am I really making a difference? Like this is on 450 acres right now we could expand it. We're planning on scaling it up. Yeah. Okay, let's forget about those 30,000 acre farmers and that we're only a tiny bit to this very complex issue or complexity that's happening out there. Sure. Yes, let's do this. Because ultimately, it's going to be better for the next generation because they're going to be out there hopefully farming too.
Craig Macmillan 29:25
Yeah. And technology and innovation has its ways of being transmitted. Yes. And being adopted. More broadly. It takes time. And it also takes different systems. It takes different systems and that's one of the things that's intriguing is we've seen things that like you said that we tried things in the past and then we moved away for various reasons. And then you say hey, wait, there's benefits. Let's go back and try this again. Or people say Well, that isn't gonna work on my system because my system is so different. Within time goes by and there's proof of concept and then it well maybe this would work and we see changes all the time being out there as a leader Kendra, I think is part of the part of the solution and you're doing that.
Kendra Altnow 29:59
And I think honestly like what we can do for our farm, and this is what makes regenerative and we could go into that as a whole nother one podcast. But I look at sustainability and regenerative, which is so great about sustainability in my mind is it's not one size fits all, you're making the decisions for your farm based on what you can do in the best possible way. So someone might still fully believe in full tilling and that's all good and great. I'm not judging you, but they might be excellent in water conservation. And we have a lot of room to grow in that right so I like that's what I think is so awesome about farming is that there is no one single way of doing things and there is no right or wrong, but I always believe that there is room for improvement.
Craig Macmillan 30:52
Exactly. Where can people find out more about you?
Kendra Altnow 30:56
Well, Langetwins.com will have information about the family winery and the vineyards and laying twins on Instagram has tidbits about sustainability and if you really want to see all of my lovely day to day posts you can follow me at Kendra underscore Jean nine you get a little bit of sustainability and a lot of benefit family animals.
Craig Macmillan 31:22
That's fantastic. So our guest today has been Kendra Altnow she is sustainability manager at length twins family winery and vineyards and she's a fifth generation Lang. Thanks for being on the podcast has been a really fun conversation. Thanks Kendra.
