The Curious Case of Corn Smut: Why This Crop Remains Unaffected
8 Aug 233 min 45 sec

In late June, a hail storm caused significant harm to Kevin's corn fields. However, one month later, he is amazed that there are no visible indications of corn smut, which is typically caused by physical damage to the corn plant. Kevin discusses the progress of his crops and shares insights on why he believes there is no disease present at this point.



00:00 Earlier on in the growing season, we had a real bad hail storm right there in wheat harvest. I brought the, brought everybody out here. We did some videos on the corn. 00:10 It was pretty well no foliage. It just looked like an asparagus plant sitting there and we felt like at that time our ear leaf and from there on up had very little damage. 00:21 And turns out that was a correct assessment of what was going on in the field. So typically when we get hail damage, 00:29 we immediately go back and we start putting some foliar fertilize and fungicide on within, you know, 00:35 48 hours of the hail damage to help heal these plants up a little bit different this year, 00:41 this crop had xyy put in the two by two fertilizer from F M C and that is our fungicide. 00:48 And what that does is it provides season long control so we wouldn't have to come back and do a fungicide application that set possibly in a severe, 00:58 uh, escape or something real late in the plant's life, which so far we've not had to do that with Ali. But I've never experienced the hail damage with hail damage. 01:07 What happens is you get what's called ear smut on this ear. When you go to harboring, it'll get in there and, 01:14 and it's real harmful to the grain and you can get alpha toxins and different things in it. 01:19 And we absolutely can't have that 'cause we can't sell the corn with that in it and we're not gonna contaminate our other corn with it. 01:26 So that's why we're so aggressive with this fungicide. But xyy actually has good control of beer smut, ironically. So it's kinda one of them deals where the stars and stripes lined up. And yeah, 01:38 it was a bad event. We got a lot of damage down here, but our, our factory to build this plant and uh, 01:45 to build that ear is in these upper leaves. These are our solar panels, catching all the sunlight to get the photos in. 01:52 And if you notice the year leaf is safe, it was no damage on that ear leaf right there. Um, you can see all the damage down below. So it's, 02:03 it's really odd not to go back and put fungicide on this. We're about R three to R four on this corn. Depending on where you are, 02:12 this is not irrigated corn. Very healthy. We don't have any disease present that we can tell in the plants. And one of the good things I guess the hell done is disease starts at the bottom 02:23 of the plant and comes up there ain't nowhere on the bottom for the disease to get to the hell done tore it all up. But I am going to, 02:28 today I'm gonna split this farm in half and I'm gonna do my standard, uh, fungicide treatment with my polar fertilizers on half the farm. 02:38 And the other half I'm gonna leave it just like you see it. Um, and I want to compare in this environment. 02:45 This is 200 bushel corn, uh, this year, thank the Lord. But I'm gonna compare if I get any yield gain. I, I've always got yield gain with my folder applications. But some people 02:58 Say, well it's your fungicide, it's giving you the big yield gain. Well we have no disease here. 03:04 What's going to be good to see is in this situation with hail does, this is our way actually hold that ear SMU off and keep it s safe and healthy. 03:13 Um, you can still see some dings on the stalks from where the hail hit. If you're in an area that you get a lot of hail. 03:20 This is something to really think about 'cause I absolutely did not plan this and um, never even thought about it. Uh, 03:29 so it's another tool in the toolbox that we can have to ensure a good quality, healthy plant. 03:35 And hopefully we'll have some high yields if that's what the good Lord has in store for. Shall stay safe.
