Specialist: Grain bin management to avoid damage in warm weather

A grain management specialist with Iowa State University recommends producers keep a close eye on bin management in warmer weather to mitigate grade damage and more.

Warmer than normal weather makes grain damage more likely.

A grain management specialist with Iowa State University recommends producers keep a close eye on what’s going on in the bins, especially since many areas have seen 70° to 80°F weather already.

High temperatures can cause stored corn to get blue eye mold, which causes grade damage just like rotten corn and it will fail the sniff test.

“By the time you smell it, you’ve got some damage in the corn somewhere, it might not be too bad, and you may be able to mix it and take the temperatures down, you won’t get rid of the damaged corn.”
Charles Hurburgh, Iowa State University Grain Management Specialist

Blue-eye mold is a discoloration down through the germ and is more prominent with cracks. One way to prevent it is to keep the corn cold.
