Farming Podcast | Corn Disease Management Strategy | XtremeAg
Are You Losing Corn Yield to Disease Without Knowing It?
In 2025, many row-crop farmers across the Midwest experienced surprising yield losses—not due to lack of fertility or weed control—but because of unmanaged or mistimed corn disease pressure. From southern rust reaching further north to recurring outbreaks of tar spot, growers were challenged with invisible yet economically significant threats to plant health and grain fill.
In this episode of Cutting the Curve, host Damian Mason is joined by Adam Byrne of FMC and Kelly Garrett, a founding member of XtremeAg, to discuss how farmers can reduce corn yield loss from disease through timely scouting, hybrid selection, fungicide strategy, and more.

00:00:00 Did disease cost you crop yield in 2025? It very likely did, and you might not even know it. That's what we're talking about in this episode 00:00:08 of extreme Ag Cutting the Curve. Welcome to extreme Ag Cutting the Curve podcast where real farmers share real insights 00:00:16 and real results to help you improve your farming operation. And now here's your host, Damien Mason. 00:00:24 Alright, I'm here with my friend Adam Byrne. He's with FMC joined by Kelly Garrett, one of the founders of extreme Ag. 00:00:30 And we're talking about disease management. And here's the thing, your company and Gail, our friend, uh, through this out there, 00:00:35 he is like, Hey, I think a hot topic we need to cover is there's a lot of disease pressure that didn't even used to exist. 00:00:40 You're from Michigan, I'm from northern Indiana. We're sitting here at my office studio in Northern Indiana. We're seeing diseases up in this climatological area, 00:00:48 northwest Iowa that we didn't maybe see three 10 years ago. And we're not sure that we're treating it right. 00:00:53 At the same time, we're talking about trying to save money because of where commodity prices are, 00:00:59 and we might be really shooting ourselves in the foot because of not doing this from handling the disease. So I want to get to the technical part of it 00:01:05 before I do, did I just outline that correctly, Kelly? Yes, you did. Uh, disease definitely cost us money in 25, regardless of what we did. 00:01:13 Fungicide, nutritionals, anything like that. It was, it was a really tough year, second tough year, second toughest year in my career. 00:01:20 So the natural inclination is, Hey man, we've got a real problem w with money because these commodity prices, 00:01:26 we gotta cut back on something. Maybe we don't need a fungicide pass. Maybe we don't need to take care. 00:01:31 You know, the, the, the disease is not that big of a problem. We can let that go. Is that where people start cutting back? 00:01:37 We hear that all the time. You know, the conversations are where can we make cuts? Where can we save money? And I think disease management is 00:01:44 right up there with weed, weed control, you know? Mm-hmm. These, those are the two things that you make those cuts, 00:01:49 you're losing money right off the bat. So I think you need to be investing those dollars into disease management and crop protection, 00:01:57 but it's a matter of how do you best spend those dollars in terms of getting that return on investment. 00:02:03 So it's not a matter of just prescriptively going out there and making applications, but it's a matter of well timed. 00:02:07 What are your targets and how are you doing it to keep those plants as healthy, reduce stress so you can keep 00:02:13 that plant kind of through the grain field. Period. Healthy and, and strong Diseases, worse diseases are worse Now, am I right 00:02:19 that we never saw things like southern rust up in this part of the world? Or did we have it and didn't know it? 00:02:25 I, I think, I think that's a, a twofold answer. Mm-hmm. I think we had it and we didn't know it. I don't think they're worse. I, 00:02:30 I believe it's just a weather pattern. Uh, Mike, Kevin's my agronomist at home, uh, he subscribes to the theory. 00:02:36 Uh, we had a snowstorm in March and the wind blew out of the south very extensively, and the ground even turned red in parts of Iowa. 00:02:43 And we believe that the inoculum from that southern rusts blew up at that time. And, and you know, 00:02:49 I thought he was crazy when he first told me that. And then he started to go through it and he's like, look, the, the, 00:02:54 the disease started from the bottom. Mm-hmm. It didn't, the disease was in the soil. It didn't go from the top down. 00:02:59 It started from the bottom up. So I believe that he's correct. So I don't know if diseases are worse, 00:03:04 but when we have weather patterns and weather changing, things like that, it, it can be worse for us and we can, a disease can come in 00:03:11 that we don't have any immunity to. Well, that's the thing I wanna get to. We gotta get a lot of stuff to cover. 00:03:15 But anyway, Adam, my question is, do you think that we're gonna get to where we have resistant fungus resistant rust resistant disease? 00:03:24 Like we now have, uh, glyphosate tolerant wheats, You know, I think, you know, in row crops? Or are we there already? No, I don't think we're there yet. 00:03:32 You know, I think in row crops, one of the advantages we have is we don't make weekly sprays like we do in specialty crops or so on. 00:03:39 Mm-hmm. So we're usually making one or two applications maximum a year Yep. For these pathogens. And I think that plays in our favor. 00:03:45 And a lot of the chemistries we're using across the board, maybe there's obviously some that will cut costs 00:03:51 and use some of the, the cheaper generic or single mode of action. But a lot of times we're using 00:03:55 multiple mode of action products. A lot of our premium fungicides have three or two modes of action, uh, very good fungicides. 00:04:01 So I think that helps, uh, delay or hold back that resistance development. So I, I don't think we're at that high risk yet. 00:04:08 And a lot of work is done at the university level to kind of collect baselines when these new fungicides come out, 00:04:12 so we can kind of track whether there's development over time. So I think right now we're okay there. Mm-hmm. 00:04:18 Um, and you know, kind of talking about, you know, to touch on what Kelly was saying about are they worse or not, it's kind of a relative thing. 00:04:25 So compared to when, you know, compared to 20, 30 years ago, yeah, sure. They're, they're worse. 'cause tar spot wasn't around then. 00:04:31 That's one challenge that's new to our, our system. But otherwise really better or worse kind of fluctuates with hybrid sensitivity 00:04:38 and how, where we're gearing some of the hybrid selection too. Ideally our tools are better 00:04:42 to manage it now than they were then. Correct. But you can also argue well on herbicide, our tools aren't better. 00:04:48 In fact, I think we're going backwards on herbicide. So I'd say I, you know, uh, one book that we, I have read, 00:04:55 we've talked about it when weeds talk. Mm-hmm. Mm-hmm. I think the weeds are getting worse and I think the diseases are getting worse 00:05:00 because we're getting worse at farming. Mm-hmm. We're out of balance so far, nutritionally, that's what's making the, the weeds tougher 00:05:06 and the chemicals don't work. And we're out of balance so far nutritionally that our plants are weaker, our plants are not as healthier 00:05:13 and the diseases make it worse. So I don't believe that the weeds or the diseases are getting worse. 00:05:19 I believe the plants and our nutritional balance is going backwards. Yeah. And I think there's a lot of truth that, 00:05:24 'cause we don't spend as much time on plant health and abio stresses that are out there. And those all we know can exacerbate the effects of diseases 00:05:33 or, you know, the impacts that are coming in and how that plant is able to, to manage those Stresses. And is 00:05:40 the highest yielding area of the field, the cleanest area or the dirtiest area? It's the cleanest area. 00:05:45 And the reason it's the cleanest area is because we have a nutritional imbalance for fertility there in the, in the lowest yielding area. 00:05:52 That's where the weeds are the worst. And we've always believed, we've always believed it's because, well, we didn't have canopy. 00:05:58 No. It's because the soil's out of balance and the herbicide doesn't work correctly. The soil's out of balance. And mother nature's bringing 00:06:03 that weed to try to correct it. The fungicides are the same way. If we can correct this nutritional imbalance, 00:06:09 we'll shore up a lot of these weaknesses. You seem kind of like the university type. I, I don't wanna be insulting here 00:06:15 because you're probably like, I'm not the university type, I'm not professor type. But you mentioned the thing about 00:06:20 university trials and all that. I, I don't know that some of the stuff that we thought was prescriptive based on university 00:06:27 recommendations 30 years ago still applies. You know, I don't think it, I don't think it necessarily does. 00:06:33 I think there's been a change. I think, I think our hybrids have changed too. So Grainville period is stretched out and maybe longer. 00:06:40 And I think the other thing that's going on is in the old days before things like Tar Spot or Southern rusts mm-hmm. 00:06:46 Which we, this year, it surprised us. Mm-hmm. It kind of came up, I don't know. We're been talking about tar tar spot every winter. 00:06:51 And now we didn't really have tar spot this year, but Southern Rust snuck in. But those are diseases that we don't have a, 00:06:58 a consistent timing in terms of onset. We don't. And so we used to be preach, you know, prescriptively, let's go in at that task so 00:07:06 that VTR one timing make a fungicide application, that was probably your best return on investment for your Crop. That speaks 00:07:12 to the nutritional problem that I talk about though. Yeah. You, I agree with you. Everybody wants to go in at R one in agriculture, we've got to a spot 00:07:19 where we just wanna hit that easy button. Yeah. It doesn't work that way. That we're going backwards because of that. 00:07:24 You said you, before we hit record, you gave a fantastic illustration about, um, justifying the investment on disease management 00:07:34 because you did some custom farming and they wanted to pull back every nickel. And the example was, um, disease cost, 00:07:41 You disease cost, uh, very poorly or very much. It, it, uh, there's two 80 acre parcels that we custom farm for a landlord. 00:07:48 You know, we rent some ground for them, then we custom farm for them. And we got into the August of the year, late July 00:07:53 of the year, the corn market was in the tank and things like that. And they did not wanna spend any more money. 00:07:58 And so there was no fungicide, there was no nutritionals or anything like that, like we did on our own crop. 00:08:02 And I would tell you that it cost them, um, 40, 50 bushel. Yeah. And so people want to make these cuts 00:08:08 and they don't wanna spend the money and things like that. Well, um, top 00:08:13 of the line fungicide, what's it gonna cost for You? Actually gave a real number. You said 170 bushels of 'em. 00:08:17 One Oh, it was two 10 over here. It it was two 20 on our corn. Yeah. 170 on that corn there's 50 bushel. Yeah. And a fungicide, 00:08:24 It's $4 corn is 200 bucks. Exactly. And what's, what's a, what's A, what's a, let's say premium fun side, 00:08:28 you run $20 not county application costs. Yeah. So 40 bucks all in max, which is very high max. That's high. There you go. Five 00:08:34 to one return on fungicide in a $4 corn market. And then you, but you also have a thing killer. You talk about offense versus defense sometimes. 00:08:42 Um, on this thing, you're doing it, if the disease is already there, you've lost Right Adam? Yeah. If you go out there 00:08:49 and you're like, oh God, you got tar spot terrible. And if I treat it Terrible is a Bad. Yeah. I'm already lost. 00:08:54 I always say if you're scouting by driving down the road looking through your car window 00:08:57 and you see it, it's too late. That's That easy button again. Yeah. It's, that's right. 00:09:00 You need to be in two with your fields. Know. I don't know if I like that when I was a DuPont intern, I did most of my scouting that way, 00:09:05 but I did get out sometimes. Yeah. If I was drinking beer, I had to get out and pee and I would go out and actually 00:09:09 stand in the edge of the That's what you might Find the early infection. Yeah. I mean, Most of the time, so about every third beer I'd actually 00:09:14 get out and check the field, but the rest of the time it was more of a drive by. You're saying that's not effective? 00:09:18 No, I don't think so. And, and I, but I think wonder, I never caught on a DuPont, But I think where we get to that tassel application, the idea is well if you spray way 00:09:25 before it's there, you're protecting yourself. I think that's a misnomer too, because with something like tar spot 00:09:29 that can ramp up very fast mm-hmm. And wipe out your crop quickly, You could be putting out the product 00:09:34 before it even has any purpose. You're almost burning your residual activity up with no pressure yet. 00:09:41 The timing has to be correct. And that's where you, you know, the easy button is to spray at R one. 00:09:45 Well then we're gonna try to do a little better. We're gonna put a preventative out. We're gonna spray at V 10 pre tassel. 00:09:50 But if it's too soon, you know, you've gotta scout and it, it's difficult. Not only do you have to scout, but then you gotta get, uh, 00:09:57 in my, you gotta get the plane service there at the right time. It's another challenge. I mean, it's, it's tough. And 00:10:03 We struggle from an agronomy perspective to talk about these things. 'cause we talk in biology and what's the best 00:10:08 approach for a grower? We don't take into those operational constraints. The getting the, the sprayer in there, 00:10:13 getting the airplane. Right. I mean those, those are Playing the weather, having the hired guys, the July 4th weekend 00:10:19 Logistical trouble. Yeah. It's easy to say what we say and then not realize the constraints the grower has because there Exactly. 00:10:24 There are real challenges. And so exactly That, That has to be juggled. But there's no doubt in my mind, looking at 00:10:30 what we've been seeing with the fluctuations and timings of these diseases, that being in tune with your fields or your hybrids, 00:10:36 it may not be the same across all your hybrids on your, your farm And, and the, when the disease comes, 00:10:41 it isn't like a cookie cutter textbook thing. Like last year we've never had southern rust like we had this year. 00:10:46 I said it was the second worst year I had that was 2014. We've never seen northern corn leaf 00:10:51 blight like we did in 14. Yeah. That was a very tough, that was the worst, worst disease year of my career. 00:10:56 You gave the example of 50 bushels on that thing and it's pretty much side by side. It's a custom farmed, uh, field and it's yours over here. 00:11:01 And same, you know, same treatment with the exception of fungicide. No fungicide. Right. One pass two passes. 00:11:08 Uh, depends on the field. Okay. Could Have been, but in this example it could have Been, I'm talking like overall average or what. 00:11:13 Yeah. Yeah. So in this example, so they lost 50 bushels. It could have been that two passes would've prevented that 00:11:17 and it could be 40 to $50. Even saying with some, you know, okay. On the math part of it, on the money part of it, 00:11:24 I guess I want to know when we said we opened this thing by saying, has this cost you money 00:11:28 and maybe you don't even know about it. Is that a reasonable number or is that an extreme number? Well, I think that's reasonable. 00:11:33 I think we see that over and over. And we had a trial in northwest Ohio this year where tar spot actually did move in this field. 00:11:40 And we had treatments where you had an untreated, you had a foliar fungicide at vtr one, a prescriptive application of a premium fungicide. 00:11:47 And then we had another one where we used in that plant fungicide, xw lfr and followed it with the timing 00:11:52 of a fungicide when the disease pressure was ramping up. So it actually ended up being 10 days later than 00:11:58 that VTR one timing. And that foliar fungicide of VTR one gave us an 80 bushel gain over the untreated. But that one with the well timed fungicide falling 00:12:07 that at plant, keeping that plant healthy gave us another 12 bushels on top of that. 00:12:10 So you're talking 92 bushels mm-hmm. Over an untreated. So it is real. I think those numbers, you know, in some fields, in some situations are very real now, 00:12:19 you know, could it be some years where the disease pressure's low, you don't get that return. Absolutely. There's so many variables that go into it 00:12:25 that the the hybrid response. Yeah. This, you know, with our 24 row planters and then our 12-year-old corn heads, we most 00:12:31 of the time quite often will have two different hybrids, maybe from two different companies, uh, in, in the, 00:12:37 in the tank when we're planting this year with that disease, it was not uncommon to see 30 00:12:41 or 40 bushel from 12 rows to 12 rows. It it, and so you just don't, and you can't out predict it because you don't know what the weather's gonna be 00:12:48 and you don't know what the disease pressure's gonna be. That's why you need to be a diversified seed portfolio. 00:12:53 But you know, you're talking about what's the response you Think, see, you think, okay, let's, 00:12:57 now we're getting into the recommendation for the farmer. Mm-hmm. The person watching this that says, Hey, 00:13:01 you know, hell, maybe you're right. I maybe I did lose, I think I did lose yield. There's some I ran through that field 00:13:05 and that normally I was off. So we got the person, uh Yep. I'm in agreement with this. So the recommendation is, first off, you think 00:13:12 you both mentioned seed. Mm-hmm. It wouldn't have been my first go to. So what are you saying? 00:13:17 Some companies seed is, would be, in my opinion, of a more northern germ plasm. Yep. And anytime you're have a disease 00:13:23 with the word southern in it. Yep. Mm-hmm. You're gonna have a problem uhhuh, some companies seed is gonna have more 00:13:28 of a southern germ plasm. And look, I go back to 14 northern corn leaf blight, you're gonna have a problem 00:13:34 and you don't know what's coming. And so, you know, it used to be we, you know, you'd have this hot number of corn 00:13:39 and my dad would wanna plant all the acres to that, you know, and we talked about that. Well then as we, as I started to learn and get older, 00:13:45 and you talk about the, this disease pressure coming in, I wanna plant the bigger portfolio that I can. 00:13:51 'cause you don't know it has to be a shotgun approach because you don't, you don't know what the disease pressure's gonna be. 00:13:56 And, and so my recommendation is plant it all the bigger diversity, the bigger portfolio seed you have, 00:14:02 you're, you're being safe. You're taking a more conservative approach and you're not gambling on said variety said company seed. 00:14:10 You know, we, when I was younger, we only planted one one company seed because you got that big discount. 00:14:15 The discount's not enough for the risk. The seed company is either liking this discussion or hitting this discussion. 00:14:21 'cause a, we're giving them credit for actually having seed that can help us with our res uh, with our, uh, tolerant, 00:14:26 I'm sorry, mitigation of the disease. Yep. And on the other side, they're saying, wait a minute, we don't want the farmer to buy only our stuff. 00:14:32 And he's saying buy everybody's stuff. No, I think I, like any of the industry partners in, in agriculture, we need to be held accountable 00:14:38 and we need to be pushed to do better at what we're doing. Right. And so I think we always say in, in, 00:14:42 at least at the university level, the recommendation should be, start with your seed choice. Start with your hybrid selection 00:14:47 because that's your first line of defense. Mm-hmm. Okay. So you know a history of what you've had in those fields. 00:14:52 So white mold in, in the north in soybeans, you gotta pick a variety that's got tolerance to white mold. You know, it's not susceptible. It's 00:14:59 Same with corn. So recommendation, we're starting now for the farm that says, okay, I did have some disease problems. 00:15:03 I'm convinced that's why I lost yield. First one is you say vary up your seed. Mm-hmm. Okay. Number two, diversify. Number two thing. Number two thing. 00:15:09 What if I, okay, I want to, I want to decrease the disease loss that I had, or I have no disease 00:15:14 whatsoever, which is probably impossible. What do I wanna do? I think you need to be in tune with your fields. 00:15:19 You need to be scouting and you'd be prepared to use Not just every third beer driving down the road. No, you're saying actually get out. Get out and 00:15:25 Look at your field. Yeah. And so when we, we do People really do that? No. They don't like to sometimes. No. 00:15:30 I think, I think the progressive good farmers actually do. I think, I think most farmers are in tune with their fields, 00:15:35 but they, um, it's different now. I think we need to be better at, you know, monitoring what's going on. 00:15:41 But then I think you need to prayer to not just prescriptively make fun. All all joking you aside, a lot of the people that are 00:15:46 with us are amateur at agronomists themselves or have consulting agronomists on staff and that's make them earn their money. 00:15:52 I mean, and not make them earn. They're doing that anyway. But they are in the field. They are really 00:15:56 Absolutely. You know, uh, some basic things. Rotation, which I'm not good at. I have a lot of corn on corn. But then pay attention 00:16:02 to the hybrids that you're following up each other with. Yeah. Don't put the same germ plasm 00:16:06 behind the same germ plasm behind the same germ plasm. You need to vary that. It's still not as good as a rotation, a cornine uhhuh corn, corn rotation. 00:16:15 But you cannot, you can't continue to stack. I, I would continue to stack Corteva genetics on top of there. 00:16:21 I would move, I would put some bear in there. I do things like that. You gotta diversify. You gotta diversify. 00:16:24 It's like your financial portfolio. You're, you're silly to put everything in one basket. Okay. Very much seed scouting, diversification 00:16:31 of, uh, germ plasm. What else do I need to know? Obviously I think we're gonna talk about treatment. 00:16:35 Yeah. Treatment. I think and, and be realistic though, you have to understand there's abiotic things that are going on 00:16:40 that contributed to yield loss that we don't see. Whether it's warm nighttime temperatures. This summer was crazy. You know, 00:16:47 everybody's talking about why didn't we see Tar Spot this year? But we saw Southern Rust, which was unique for us. 00:16:51 It came further north. Mm-hmm. And earlier than we've seen. Right. But Tar Spot didn't blow up. Why? 00:16:55 Well, we had a lot of warm nights, nights that didn't get below 80 much. 00:17:00 Mm-hmm. The upper seventies. And when you don't dip down to those cooler nights, you lose yield. 00:17:05 I mean, there's physiological factors that have been studied that you need those cooler temperatures to. 00:17:10 So there's other things that lead to yield loss. It's not just what we think of weed competition or diseases. Right. There's other factors that are stresses that can, 00:17:17 can make the diseases worse. And those are Less a factor. You're in Michigan, I'm in Northern Indiana. 00:17:21 Those, those things are less factors where he is in Northern Iowa than it would be. Like our friend down in Matt Miles talks about nights 00:17:28 that they stayed 90 degrees. That's right. But, uh, we still have some of that pressure here. 00:17:31 Yeah. I, I got seed, uh, I got diversifying my seed. I've got, uh, scouting, I've got, uh, the germ plasm, uh, and rotation. 00:17:39 Um, and now I've got the actual treatment with the stuff. Yeah. You, you make uh, fungicide. 00:17:44 But there's a bunch of other stuff. There's some that is way expensive. 'cause it's got seven modes of action. 00:17:49 There's this other kind that have been on the shelf for a long, long time. What do I need to think about when I want 00:17:53 to do my treatment? Well, in, in the custom farming example that I gave you, the farmer, the, the, 00:17:59 the grower there didn't feel like they had that in their budget. Mm-hmm. I leave room for it in your budget that 00:18:04 that's not the place to cut. So leave room for that in your budget. I would tell you like in a year when you have depressed corn 00:18:10 prices, dry fertility, your dry fertilizer, that, that's where you should find a spot to cut 00:18:16 or maybe your seed population. Mm-hmm. Find a spot to cut there. Don't find, don't don't cut on disease 00:18:21 Mitigation. Yes. Don't, that's not a spot to cut. Look at, look at what it did this year. Look at what can happen. Yes. 00:18:27 Then if you don't need to use it, great. You've got that room in your budget, but you need to leave room for that in your budget. 00:18:33 Anything else on this thing? Because disease, we, you are convinced of it and you're not just, oh, I don't farm Michigan. 00:18:38 That won't affect me. You, your FMC has a global footprint. Yes. This is not a Michigan problem. 00:18:44 Disease cost, disease cost yield in a lot of geographies. Yes. Fair. Yeah. Fair. It's, it's, to me it's the number two factor. 00:18:52 You have to be prepared for weed controls first if you don't have clean fields with weeds 00:18:56 and the disease problem's, not even a problem. Right. You, you didn't get there, Adam, Did people let their foot off 00:19:00 the gas because of the money? Or are they truly got surprised with diseases that like we didn't see before? Or a little bit of both? 00:19:06 Maybe a little bit of both. I think we did get caught off guard with Southern rust, but it's not any different than being caught off guard 00:19:13 by when tar spot emerges. Like if we're prepared and kind of budgeting for this, it shouldn't have cut a sc guard that much. 00:19:19 You know, Southern rust is novel, but we should have been ready to react. I I think it the first time something 00:19:25 happens, we get caught off guard. I I think the answer to your question is yes, people didn't want to react because of the money. 00:19:31 Yeah. But then also the first time something happens is bad. When is the first time we saw a tar spot? 21? Well, 00:19:37 I can't remember. 2018 was probably the first bad year. It showed up in over in your neck of the woods in like 2015. Yes. Yes. There, there you go. 00:19:43 That's Yeah, I remember, you know, I was talking about extreme mag when we talked about it in Illinois, but the first time when a disease comes, 00:19:50 it just decimate thing nobody's prepared. Right. Neither corn leaf black, 14, 15, 18, things like that. 00:19:55 With tar. With tar spot. Now 25 with southern rust. Yeah. And the next time it comes, we're better prepared 00:20:01 because of the expensive education We've received. Last thought on this, you know, there's a lot of pressure on things like monocropping and you know mm-hmm. 00:20:08 No rotation, all that. And then just like, there's people that are saying we wouldn't have 00:20:13 to have use antibiotics if we didn't have those, uh, pigs in those tight confinement or whatever. Are, are some of our practices like cover crops, um, 00:20:22 and some of the things he's doing, is it going to mitigate the disease thing or is the disease thing such that just kinda like these damn weeds 00:20:30 that we have a hard time tilling now. They they can outpace us even, even though we changed some of our practices. 00:20:35 I think we may make management decisions like rotation or not that could short term impact some disease pressures. 00:20:45 But no, I don't think we're gonna mitigate or get rid of the disease pressure. It's going to, it's gonna cycle somehow some way. 00:20:50 I think we're always gonna be dealing with challenges to the plant health and, and how can we keep that return on investment, 00:20:57 but that grain fill as best as we can. And I think that's the reality we're gonna to as A farmer with 25 years of experience. 00:21:05 Do you think that there's some practices you can do that can also, besides the treatments and the, we talk about is cover cropping change? 00:21:11 This? Does enough rotation lessen The pressure? It does. You know, like we talk about 00:21:15 the corn on corn penalty. Yeah. Corn on corn yield penalty. What? It's it's real, it's there. What is it? It's, 00:21:21 We've always thought it was, it's not fertility at this point. It's not. It's not. It's not. And I, I, 00:21:24 that's what I was leading into. I'm glad you said that. I don't believe that this nitrogen credit, 00:21:29 which I don't believe exists in now with the re you know, more education, I've got this nitrogen credit is the reason 00:21:35 that the rotation yields better that had what if it's disease? Yeah. What if disease is 50% of it? You know what I mean? 00:21:40 I I don't think it's fertility at all. No. So if you are going to limit your rotation mm-hmm. You've really gotta have your intent off. Well you, 00:21:48 You know, you're raising the risk for things like crown rot or stalk rots. I mean, you know, You're, which also happened this year. 00:21:53 Absolutely. It was a big year in areas for mm-hmm. For that. Yeah. So, you know, you're raising your risk by management decisions 00:21:58 or you're lessening your risk with some decisions, but you're going to, it's gonna cycle back around. I mean, I think we're always gonna be dealing 00:22:04 with disease management one way or another. Name's Adam Byrne, the company's FMC.
