Herbicide Injury on Corn Inbreds

Glenn Nice, Department of Botany & Plant Pathology

Herbicides can sometime react differently with different inbreds of the same plant species. Although Accent is labeled in field corn, field corn grown for seed, and popcorn, it can sometimes cause unusual responses with certain inbreds. This variable response can be a result of different rates of breaking down the herbicide in the plant. When growing a corn inbred it is always important to consult your seed company representative to find out if the inbred is sensitive to the selected weed management program.
