From 1997-2008, the estimated reduction of soybean yields in Kansas have averaged 2.7 million bu/yr for seedling blights, 6.2 million bu/yr for charcoal rot, and more than 2.4 million bu/yr for other root diseases (including SCN, SDS, Phytophthora and Fusarium root rots).
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.
