Ear Rots and Mycotoxins

Aspergillus ear rot of corn

Ear rots of corn annually reduce yield and grain quality in the United States. Different fungi cause ear rots, and some of these fungi are able to produce toxic compounds, know as mycotoxins. Mycotoxins can be toxic to humans and livestock, and are carefully regulated in food and feed.

A partnership was formed in 2012 to understand and combat ear rots and mycotoxins.  This partnership involves the University of Arkansas, Michigan State University, North Carolina State University, Purdue University, Texas A&M University, and is funded by the USDA National Institute of Food and Agriculture. The goal of this partnership is to  provide new resources to farmers to aid in ear rot and mycotoxin management.


The Crop Protection Network (CPN) recently released a series of 5 publication on corn ear rot management. Visit them by clicking on the links below:
