The cool weather early in the planting season makes generalizations about seedling diseases difficult. Although cool soil temperatures are favorable for infections by Pythium and Fusarium, soil moisture was not good for these two disease-causing fungi until last week (week of May 6), when rainfall saturated the soil. If there is another large rainfall in the next week or so, some seedling disease problems may occur, and the types of diseases depend on the temperature this week and next week. This article discusses identification of the possible diseases.
