This year does not appear to be a particularly bad year for ear rots, but there are a few unusual occurrences. First, there seems to be more corn earworm damage than usual this year. This can lead to increased Fusarium ear rot. Second, I have noticed that Diplodia ear rot is more prevalent than usual. Neither of these observations constitutes a major outbreak, but it might be worthwhile to look for these problems. Also, if cold, wet weather persists, be on the lookout for Gibberella ear rot. Corn that has been frosted can be very susceptible to Gibberella ear rot if it remains in the field for a long time
