Abnormal Corn Ear Development

​Environment or chemical stress during the vegetative and early reproductive stages (V5 to R3) of corn can cause abnormal or malformed ears. Distinctly different symptoms develop depending on the timing, type, and severity of the stress corn undergoes. Pesticide applications can be a source of stress on corn if application occurs outside of product label conditions or other stresses increase corn susceptibility.
