This Podcast is sponsored by the UMN Extension Integrated Pest Management (IPM) Program. In this week’s podcast, we feature Dr. Dean Malvick, University of Minnesota Professor of Plant Pathology. Dr. Malvick discussed what diseases he is keeping an eye out for in Minnesota soybean and corn:

Soybean diseases

White mold symptoms are beginning to occur, though the next few weeks will tell how severe it is region-wide. Dr. Malvick explained how we are past the window where treatments would be effective for white mold, but growers should consider varieties for next year that have partial white mold resistance, though no variety is entirely immune.

Sudden death syndrome (SDS) of soybean is caused by a fungus that infects roots early in the season, and symptoms are generally not visible until later in the season. It has been confirmed in most counties in the southern half of Minnesota. Varietal selection and possibly seed treatments can be tools to consider for next year.
