Gibberella ear rot of corn
Gibberella ear rot is caused by the fungus Gibberella zeae, also known as Fusarium graminearum. It usually begins at the tip of the ear and appears red or pink, or occasionally white. Gibberella sometimes rots the entire ear. Infections occur more commonly in cool, wet weather after silking and through the late summer. Gibberella can produce vomitoxin and zearalenone.
