Corn ear rot problems are often related to how long the corn stands in the field in the fall, the amount of second-generation European corn borer damage, and the late-season weather. This year, corn dry-down is progressing more slowly than anticipated and there was a healthy second generation, so there are more ear rots being reported than usual. The dry weather that was widespread earlier in the summer resulted in someAspergillus infection (the fungus that produces aflatoxins).
