This growing season has been favorable for development of sudden death syndrome (SDS) in Minnesota. This disease is developing earlier than normal in my research plots in Waseca, and I expect it to become obvious soon in many soybean fields. The earlier it develops the more potential it has to cause significant yield loss. SDS has been spreading and we are requesting help to determine where it occurs in Minnesota. SDS has been concentrated in south central Minnesota in past years, but it could occur almost anywhere in the state.
