Gibberella ear rot is the most common ear rot in Ontario and unfortunately has resulted in not
only significant yield losses to farmers but reduction in corn grain and feed quality due to
mycotoxin accumulation. Although the pathogen Gibberella zeae (Fusarium graminearum)
produces several mycotoxins including Zearalenone (ZEN) and T-2 toxin, the most economically
important in Ontario is Deoxynivalenol (vomitoxin or DON).
