Soybean Production
- Wet, Cool Weather Favoring Early Season Soybean Diseases. Pythium has been identified in several poor soybean stands. If moisture and warmer conditions continue, watch for Phytophthora.
Corn Production
- Seedling Diseases Appearing in Corn. Cool, wet conditions are leading to the development of diseases caused by Pythium and less frequently, Fusarium.
Alfalfa Production
- Watch for Alfalfa Weevil Adults on Regrowth. First cuttings of alfalfa are later than normal this year, likely leading to increased alfalfa weevil activity.
