Three corn cobs with common ear rots. From left: Fusarium ear rot, Gibberella ear and Diplodia ear rot.

Scout for Corn Ear Rots

Several corn fields scouted in northeastern South Dakota counties were found with ear rots. Ear rots were mostly prevalent in areas that experienced hailstorms in the recent past. Ear rots in corn are caused by a few fungal pathogens, and which ear rot develops depends on the weather conditions.
