The Connection Between SCN, SDS, and Soybean Yield Loss

New data from the Crop Protection Network shows Soybean Cyst Nematode and Sudden Death Syndrome are two of the leading causes of soybean yield loss. Zach Trower, an agronomic service representative with Syngenta, talks about the connection between SDS and SCN and the impact on the bottom line.

“So, we look at Soybean Cyst Nematode, that’s probably one of the largest pests for soybeans nationwide. It can cause about $1.5 billion in crop loss every year. Usually, you’re gonna find it most soybean fields throughout the country to some extent, some fields obviously a little bit worse than others. But the connection with Soybean Cyst Nematode and Sudden Death Syndrome is that SCN is actually going in there and attacking those roots and causing openings. We can actually see the disease, Fusarium virguliforme that actually causes SDS, get inside those roots through those openings, that wound caused by SCN. So, when you get into some of those higher pressures, we can definitely see them interact. And as one’s going in there early in the season and opening up those roots and the other ones infecting, we can see them be a little additive and cause a higher problem for those soybeans.”

Trower talks about ways growers can protect their soybean crops against SDS and SCN.

“SCN is obviously very heavily influenced by selecting varieties, right? That’s going to be our biggest thing for SCN is making sure we have the right variety in that field to combat that pest, making sure we’re watching out for resistance and all those other deals. So, when I think about SDS, there’s three major things that I see influence SDS. The first one is compaction. The second one is the variety that we choose. And then the third one is making sure we have the right seed treatment on.”

Compaction is one of the first things farmers have to watch out for.

“Compaction is gonna be the number one driver. If we have a lot of compaction, that soil is going to have a hard time draining, going to stay wetter longer. It’s going to allow that disease to really infect those soybeans. When it comes to variety, I mentioned that with SCN, it’s really important. But when I look at the variety for SDS and making sure that we have a good SDS score on that plant, it’s really, really critical. Otherwise, if we don’t have that good SDS rating in those soybeans, it’s going to be really hard to keep that field clean because we have to really let that seed help us along. And then finally, that seed treatment aspect, we got to make sure we have a really good crop safe seed treatment on there for SCN and SDS, and that’s why I really look at Saltro® seed treatment.”

Saltro Fungicide Seed Treatment gives growers solid protection from yield loss.

“Saltro seed treatments can really give you that best-in-class SDS and SCN protection, but we don’t have that baggage around safety. A big thing that I’ve noticed with growers is we’re trying to lower our populations with soybeans. Plant less to try to get more of an optimum stand out in our field to optimize that yield and optimize some of our cost savings with our precision equipment. If we’re going out there with a product that’s not crop-safe like some of our older seed treatments out there, we can see some baggage there and even potentially lower our stand more than we really want to. So, I really look at Saltro Seed Treatment. You get that best-in-class protection, but you don’t have that baggage of thinning out the stand or crop response from it.”
