Soybean Cyst Nematode and Sudden Death Syndrome are known causes of soybean yield loss, but a new disease, Red Crown Rot, is starting to show up with similar results. “Like SDS, Red Crown Rot is very similar in that it also gets in the plant early in the season and doesn’t express itself until late as well with this foliar leaf scorch,” said Syngenta Agronomic Service Representative Matt Geiger. “You need to control both of those with a seed treatment, you want to prevent them from getting in the plants when they’re young.” Distinguishing between Red Crown Rot and SDS can be difficult. “They look a lot alike. You need to look at the roots late-season if you want to try and identify between the two because at face value you think you have SDS because the foliar scorch looks very similar.”
