So far this season, weather in Iowa has been cool and wet. NOAA’s mid-term weather forecast for the coming 30 days shows that Iowa will have cooler than normal temperatures with above normal precipitation. A cool and wet summer is favorable to soybean diseases, especially foliar diseases. If the weather trend holds, we should see more foliar soybean diseases late this season than a normal year. Fungicide is a means to controlling foliar diseases. To determine if a chemical control should be applied to manage the foliar diseases, scouting is critical.
