  1. Phytophthora Damping-off and Root Rot of Soybean

    Feb 5, 2019

    Phytophthora damping-off, root, and stem rot have been the most destructive diseases of soybeans in Ohio for more than 60 years. When rainfall saturates fields soon after planting, high incidence of seedling damping-off can result in yield losses greater than 50 percent in individual fields and require replanting. Statewide yield losses average 11 percent in years with wet springs and 8 percent in years with more normal planting seasons. The disease is most severe in poorly drained soils with high clay content.
