Minnesota farmers reminded of chlorpyrifos BMP’s

Minnesota farmers using a common insecticide to treat soybean aphids are being reminded of important Best Management Practices.

University of Minnesota Extension entomologist Bob Koch calls chlorpyrifos an important tool for controlling aphids.

But, he says growers need to be mindful of BMP’s developed by the Minnesota Department of Agriculture.

“They’re monitoring different streams, rivers, and lakes around the state and have been finding more and more detections of chlorpyrifos in those surface waters.”

Koch tells Brownfield some key points from the chlorpyrifos BMP’s are maintaining setbacks from permanent water bodies and applying large droplets when possible.

He says respirators are usually required when working with the chemical, and he advises applicators to pay careful attention to label specifications.
