Phytophthora sojae and P. sansomeana have the potential to rob yield from Michigan soybean producers. It has been 20 years (1993-1997) since a detailed survey has been conducted for the Phytophthora sojae pathotypes (races) present in Michigan. We often receive questions from growers and seed dealers regarding which Rps resistance genes, trait packages and seed treatments 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...
Performance of the graduate student and project progress will be evaluated monthly through lab meetings. Resources developed such as isolate collections will be made available to soybean breeders for the screening of germplasm resistance.
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.
