Sclerotinia stem rot of soybean research featured in the FABI International Seminar Series 2021-10-05
Dr Damon L. Smith of the University of Wisconsin-Madison (UW-Madison) was the guest presenter at the September FABI International Seminar Series on 30 September. He spoke about “Using research-based solutions for managing Sclerotinia stem rot of soybean”. Sclerotinia stem rot (SSR), caused by the fungus Sclerotinia sclerotiorum is one of the most important diseases of soybean in the Midwest USA. In the last five seasons, SSR has resulted in significant yield loss in the Midwest region alone. Management of SSR is complicated and requires a multi-pronged approach. Researchers in the Midwest U.S. have been working to refine the integrated management strategy for SSR, which includes using resistant varieties, modifying row spacing and planting population, crop rotation, and fungicide applications. In addition, researchers are developing new techniques such as smartphone-based forecasting systems and using RNAi technology to combat SSR. The presentation outlined the latest SSR research-based tools and how they have been integrated to improve SSR management of soybeans. Damon also looked ahead and explained how some of the new technologies being developed may eventually be used to manage SSR.
