In this week's CropCast, hosts Seth Naeve and David Nicolai welcome Dr. Dean Malvick, University of Minnesota Extension Plant Pathologist for corn and soybeans. Dr. Malvick dives into the 2025 growing season to discuss the development and yield impact of key crop diseases. He provides a timely review of Southern corn rust and corn tar spot disease biology, detailing their spread across Minnesota and adjoining states this year. Dean also outlines the knowns and unknowns regarding the progression of these corn diseases in relation to weather, wind, and crop rotation. Finally, the discussion covers the complex management strategies, including hybrid selection and the critical timing of foliar fungicides. We didn’t forget to ask about soybeans.
