Herbicide-Resistant Weed Struggle Unmatched inU.S. Agriculture

摘要

IN 2021, IT'S RESISTANT WEEDS that remain American agriculture's Achilles' heel."The evolution of herbicide-resistant weeds is one of the most significant developments in agriculture today," says Dr. Aaron Hager, Extension Specialist, Weed Science, at the University of Illinois. "In terms of tough issues facing today's farmers, thishas to rank right at the top."This view is supported by a majority of U.S. ag retailers, who play a key advisory role for growers. In a weed survey conducted by Meister Media sister publication CropLife during the fall of 2020,40% of respondents said that in their opinion, the stateof weed control in agriculture was "volatile, as bad as I've ever seen it." Another 37% said weed control remained volatile, "but was not as bad as it once was.'' Only 16% of survey respondents said weed control was "getting better" than in prioryears. The remaining 7% weren't certain what the current state of weed control in agriculture was like.
