Atrazine is the main weapon against weeds in sweet corn, with few alternatives
Date:5/19/2010

n with atrazine and tillage.

One of Williams' prior studies was to find sweet corn varieties with larger canopies that would provide more shade, making it more difficult for weeds to gain ground. He noted that there is progress in using other physical and alternative weed control tactics such as flaming, mechanical weeding, and crop varieties that suppress weeds, but use of such tactics requires more management than spraying an herbicide.

"If the regulatory decision is that we can't use atrazine in ways that ensures protection of the environment and human health, then growers will need immediate, economically viable weed management alternatives", Williams said. "For now, such alternatives to replace atrazine are not well developed or demonstrated."
