This spring’s cool and wet weather, with accumulated degree days behind average, favors seedling diseases. Fungal pathogens have been reported to cause poor seedling stands in both corn and soybean fields. Infected soybean seedlings are rotted and can easily be pulled from the soil. Infected corn roots are discolored, soft or mushy. Mesocotyles also may have a brown discoloration. Infected corn seedlings often appear yellow or stunted.
