Late Season Corn Disease: time to scout!

Reports are coming forward of various disease problems in this year’s corn crop. Some of these diseases include ear rot, anthracnose and stalk rots. Wet warm late season weather can increase the possibility of stalk and ear diseases and worsen any already present. Now is the time to scout fields to determine which may have problems. Farmers may decide to harvest fields with stalk rot earlier to avoid loss. They may also look for varieties that are more resistant to stalk rots when buying next year’s seed, especially in fields that have a history of problems.

Several links are included below which cover current year disease reports in the Corn Belt as well as background on ways to identify and manage the problems.
