Farmers frequently encounter abnormal corn ears in their fields when the crop experiences stress conditions, such as drought, temperature extremes, disease and insect injury, or misapplied chemicals. These abnormalities can affect yield and grain quality adversely. We’ve prepared a poster highlighting ten abnormal corn ears with distinct symptoms and causes. The purpose of the poster is to help corn growers and agricultural professionals diagnose various ear disorders.

A reduced 11 x 14 inch version of the poster is available online.

The full sized poster is available online.

The OSU College of Food Agriculture and Environmental Sciences Communications & Technology section (contact information below) has 26 x 33 inch copies of the poster available for distribution. The poster is printed on plasticized coated paper for durability. Poster cost is $11.25 plus shipping. Ask for “Abnormal Corn Ears” poster” ACE-1.
