 My name is Sam Markel. I'm an extension plant pathologist at NDSU at September 1st, so it's fairly late in the growing season. I'm standing in a soybean field in Sargent County and the field looks really quite good. It's lush, it's green, it's thick, it's all the things that you want when you're growing soybeans. But it does have a disease that's new to the state. It's called frog-eye leaf spot. Frog-eye leaf spot has been a problem in the eye states and the central plains and the mid-south for some time. We've been expecting it to show up in North Dakota at some point and it has. And so when you're looking at frog-eye leaf spot, at least late in the season, what you're going to see are lesions and they're generally circular. They can be a little bit angular. They tend to have a brownish, maybe even grayish center and it's got a fairly distinct ring around the lesion that usually is dark brown to purple. You sometimes can see some graying in the middle of that lesion. If you flip this over, you often can see gray molding or gray mold of some sort in the middle of that lesion and that's usually usually a good diagnostic tool to identify frog-eye. Now there are a few diseases that look similar if I will stick to for one but we do know that this is frog-eye and this is new. So frog-eye leaf spot is seed-borne and residue-borne both. So you can get it in infected seed but usually once you get it in a field, this will survive on the residue for a couple years. So if you have frog-eye, you'll be at risk of frog-eye the next time you put soybeans in, if you only rotate out to corn or wheat or something for one year. The disease can be economically important. It can cause yield loss and it has in other parts of the country but a lot of that depends on the time that it shows up and the severity. So we look at it generally starting after flowering all the way maybe up to r4 or podfill and if you have it at that point you might want to think about managing it. Obviously we're long beyond that so we're not worried about yield loss this year. We're not worried about yield loss occurring in this field but it is something that we need to know about. So at this point we don't really know how widespread frog-eye is. We're out serving right now to try to get a better handle on it. Frog-eye is brought on by conditions that are hot and humid. So we've had a hot and humid summer so it's sort of not surprising that we had the conditions that would facilitate this disease. It's also not surprising that I'm very close to a shelter belt. Lots of times higher humidity because of lower winds sometimes longer due periods. We're out serving right now in the southeast corner of the state. We're trying to get a better understanding of where this is at. This winter we're going to be looking at the frog-eye and making sure that our fungicides are effective because you can manage it with fungicides as long as the pathogen's not resistant yet.
