The following information is a Web Extra from the pages of Farm Journal. It corresponds with the article “Moldy Corn Alert” by Kim Watson. You can find the article in the February 2010 issue.
Information provided by the University of Minnesota Extension:
This fall the harvesting season was a challenging one to say the least. Dealing with moldy corn was a primary concern.
The University of Minnesota Plant Disease Clinic reports that many samples came back Cladosporium, a genus with which no known toxins are associated. You can send samples to the clinic to diagnose and help identify mold and kernel infection. Call them at (612-625-1275) for more information.
