Voluntary Water Quality Best Management Practices (BMPs) for all agricultural herbicides and specific BMPs for acetochlor, alachlor, atrazine, metolachlor and metribuzin were developed by the Minnesota Department of Agriculture (MDA), University of Minnesota Extension and other interested parties in 2004 and updated in 2008. Subsequently, the BMPs for all agricultural herbicides and acetochlor were revised in 2010.
Voluntary Water Quality Best Management Practices (BMPs)
The purpose of the BMPs is to prevent and mitigate the degradation of Minnesota's water resources from agricultural herbicide use. Since their development, the BMPs have been promoted by the MDA, pesticide companies, pesticide dealers, University of Minnesota Extension and others.
The MDA is evaluating the adoption of BMPs by corn growers through grower, pesticide dealer, and applicator interviews, and is evaluating the effectiveness of BMPs through ongoing water quality monitoring and in-field studies.
An acetochlor BMP poster (Figure 6) jointly developed by the MDA and Acetochlor Registration Partnership (ARP) in 2008 is available by calling 651-201-6141 or by downloading from the MDA website.
