Corn and soybean disease: Strategies for effective management in 2022
Dr. Dean Malvick, U of M Extension plant pathology specialist and crops program leader and professor of plant pathology discusses corn and soybean diseases he has observed and what might yet appear in 2022. Since it was first found in Minnesota in 2019, the fungal pathogen that causes tar spot in corn has spread from southeastern Minnesota to as far north and west as Stearns County in three growing seasons. Tar spot-related topics included scouting strategies and identification, when symptoms are likely to be observed, and what research has told us regarding proper active ingredient and application timing for managing tar spot with a foliar fungicide.
