Alternatives to Triazine Herbicides in Iowa Corn Production

Abstract

<p>This report explores triazine herbicide alternatives in corn production given the possibility of restricted atrazine use. We identify three key results: <ol> <li>Restricting atrazine application rate to 1.5 pounds of active ingredient per acre would generally not reduce weed control or corn yield.</li> <li>An atrazine ban might not decrease weed control or lower yields provided farmers can manage alternative strategies efficiently.</li> <li>A triazine ban would likely increase costs, labor, and total pounds of active ingredients of substitute herbicides, but would not necessarily decrease weed control.</li> </ol></p>
