In Minnesota five soybean pathogens, Heterodera glycines (Soybean cyst nematode), Phialophora gregata (brown stem rot), Phytophthora sojae (Phytophthora root and stem rot), Sclerotinia selerotiorum (white mold), and Fusarium virguliforme (sudden death syndrome) cause more than 50% of the disease yield loss in Minnesota. With the exception of SCN these pathogens are all fungi or closely related organisms. Varietal resistance is the most reliable and economic method of controlling these diseases. The soybean breeding program continually evaluates sources of resistance and incorporates their disease resistance into soybean breeding lines.
The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
