Delayed planting coupled with the wet spring may mean this is a good year for a fungicide application on corn. Wet conditions have favored the development of some foliar diseases within the canopy, and many fields are delayed developmentally due to later planting. In the past two growing seasons, most of the corn in Iowa has been flowering by mid-July. This year, it will be another 10 days or more before widespread tasseling occurs in the state. When diseases start during early grain fill, this increases the risk of reduced yield.
