Phytophthora sojae and P. sansomeana have the potential to rob yield from Michigan soybean producers. It has been twenty years (1993-1997) since a detailed survey has been conducted for the Phytophthora sojae pathotypes (races) present in Michigan. I often receive questions from growers and seed dealers regarding which Rps resistance genes and trait packages should be used for Phytophthora stem and root rot management. This survey of pathotypes and examination of management practices (seed treatments and resistance packages) will enable us to provide up-to-date information to Michigan soybean farmers. Phytophthora sansomeana is a newly described species that can cause disease on soybean,...
We are currently sampling fields within Michigan and have sampled 57 so far. this fall we plan on starting to bait the fields that we have collected from.
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.
