The following news article is from Paul Vincelli, Plant Pathology, University of Kentucky College of Agriculture.
Last month, I wrote an article about Diplodia ear rot, our most common corn ear rot in Kentucky. Diplodia has no known associations with mycotoxins in corn. Gibberella ear rot is associated with mycotoxins and in some cases may look very similar to Diplodia. Normally, Gibberella ear rot is not a widespread problem in Kentucky, but this is not a normal year.
