Acetochlor is a herbicide widely used on corn in Minnesota, and to a limited extent, also on soybeans. Common trade names for acetochlor include Harness, Keystone, SureStart, Surpass, Volley and Warrant. It, along with atrazine, another widely used corn herbicide, has been frequently detected in Minnesota's surface water, at times at elevated levels. The following sections explain acetochlor's role in Minnesota agriculture, its impact on Minnesota's environment, and actions being taken to reduce the presence of acetochlor in water.
