The purpose of this project is to mitigate soybean root diseases in Kansas. Therefore, the objectives and methods will be to (1) Discover resistance to fungal pathogens: SDS, Fusarium diseases, and charcoal rot through the use of high-throughput pathogenicity assays and field tests; (2) Evaluate management strategies for fungal pathogens: SDS, Fusarium diseases, and charcoal rot with emphasis on cover crops and testing fluopyram, a widespread fungicide; and (3) Assess the impact of a re-emerging root pathogen, Phytophthora sojae, in southeastern Kansas through the collection of isolates, testing agains commonly used fungicides, and establishing race information for this pathogen.
