Last year we began testing soybean varieties for tolerance to sudden death syndrome (SDS). Funded by checkoff dollars, we have repeated the test this year with varieties submitted to us by private companies. The SDS tolerance test was conducted in a field near Ames, Iowa. To ensure uniform and consistent disease pressure across plots, we planted dry oats infested with the SDS pathogen along with the soybean seed. Our field experiments show this method, developed by our project at Iowa State University, can provide a consistent level of disease pressure. Details of this method are available upon inquiry.
