This project addresses the importance of the interaction between Phialophora gregata (pathogen causing brown stem rot) and soybean cyst nematode in reducing yield of soybeans in Iowa. Results from this project will provide information needed to make sound decisions for the management of BSR. Specifically, it provides information for the first time on the amount of yield loss that occurs in Iowa due to 'hidden' disease caused by genetic type or genotype B of the BSR fungus. This research also is determining if the most widely planted SCN- and BSR-resistant cultivars in Iowa are providing protection against genotype B of the BSR fungus. The results from the research also will indicate if a...
