Gibberella ear rot

Gibberella ear rot is caused by the fungus Gibberella zeae, also known as Fusarium graminearum. It can be identified most readily by the red or pink color of the mold. In some cases, the color appears white. It usually begins at the tip of the ear. Gibberella will sometimes rot the entire ear. Gibberella ear rot infections occur more commonly when the weather is cool and wet after silking and through the late summer. Gibberella can produce vomitoxin and zearalenone.
