 Good morning. My name is Henry Jordan. I'm the Variety Tested Manager here at Auburn University and I'm standing in an early planted maturity group for soybean trial at our E.V. Smith Free-Thirk Center. So on my right is what a typical variety trial would normally look like. On my left is what happens when we have extreme nematode pressure. So a little bit about this trial. It was planted on April the 22nd. It was an early planted trial maturity group for soybeans. I came out in mid to late June and took pictures, variety specific pictures of this trial and for the most part everything looked like this variety on my right. When I came back about a month later in July you can see what we've got on my left. So one thing I want to bring up here is the importance of variety selection. Choosing the right variety can either make or break a grower in certain conditions. So obviously this variety on my right is very tolerant compared to the variety on my left. So here we can see some pretty severe symptomology caused by a root not nematode and what actually happens is the J2 phase of the nematode actually enters the root and creates these galls around themselves. In that field we've got a foliar disease that we also have nematodes. So Claire has dug up a root. I don't know if you can get close enough you can see the massive galling on the root system caused by the root not nematode. So when you see the inner vent of the root, that's a fungal nematode. Let's come in probably with the interaction of this nematode that opens up the roots and then the fungus came in and you saw how much death it caused. But everything does not die and some of the roots are still surviving. You can see the plant is put on extra roots in the top trying to make up for the damage caused by the root. And this one we can clear with some pods. It still survived. Lots of pods on this one. So this is a bad situation with root not nematode. Here we are in the soybean field where we pretty clearly have some symptomology going on. So in order to make sure that it is the root not nematode we're going to take a quick soil sample. So what you're going to want to do is take your soil probe and place it pretty close to your root system and then go ahead and take that soil sample. You're going to want to get a few places along these rows and then you're going to mix these samples together in a ziploc bag and then you're going to want to treat it like a gallon of milk. You don't want it to get too hot. You're going to want to keep it refrigerated so that you can then send it into the Auburn lab and they can tell you if you have what type of nematode you have and also the population number and then that can help you make better management decisions. On this variety that you see we still have root not nematode damage and you can see the galling here but it's not as severe as in that last plot. So we do appear to have some tolerance on here in this plot and you notice we don't have as much of the fungal disease as either. So this variety is a little taller much smaller has more yield but it still does have the gall. So the nematode is here but not causing it severe damage. So we'll just call this one more tolerance. Here in this variety this you notice the roots of this plant which looks so lush and green it has a good yield on it no fungal disease has also very little nematodes but and the root system is quite clean. So this one is definitely looking very good. We did we specified he was not nematodes on it but it's definitely not got the galling so it is a very tolerance. So the variety trials are extremely helpful that we can look at all these different genetics and see the expression of all these varieties when we do have a nicely root not excessive yield on fungal disease. So if you have your soybeans with showing galls like this one because of root not nematodes you may need to switch varieties and get a very nice root system like this one. So this plant is showing the ability to fight the root not nematodes and if you have the root not nematode in your field you're going to have to have a very good variety that is tolerant to this problem and also you're going to have to do your management practices accordingly to help your soybean plant fight the nematode. So fungicide insecticide keep the pests away keep diseases away help your plant to fight the nematode. Also during the winter you can rotate your field with some options like wheat rye and black oats to help the population of the nematodes keep down. Another option you have is to be certain that when you buy your seed they come with a nematocyte treatment on on the seed and that way you're going to have another help to have your plant healthy and fighting the problem.
