You may have moldy corn, but is it a real problem?
Ohio State University specialists say before abandoning a cornfield, make several determinations. They say ear mold may not be widespread within a field, and it may not be the variety that causes mycotoxins.
Before making a decision:
-
Walk you fields, and examine multiple ears for signs of ear rot.
-
If you have an ear rot, determine its variety and whether it produces mycotoxins.
-
If the mold is a hazard, determine how widespread it in throughout the field.
-
Examine 50 to 100 ears at multiple locations spread out throughout the field.
-
In the case of aflatoxin, a black light test should be checked if it fluoresces.
-
A positive black light test does not prove the toxins are present with the aflatoxin.
Here's a guide to help you identify molds in corn.
