NEW Draft Water Quality BMPs for Atrazine

The MDA is requesting comments on the Draft Water Quality Best Management Practices for Atrazine.

The MDA developed voluntary Water Quality Best Management Practices for Atrazine BMPs in 2004 and revised them in 2011. Currently, the MDA is again revising these voluntary BMPs in response to current agricultural practices. The MDA requests comments on the document, which represents a revision of best management practices developed in 2004 and revised in 2011.

Written comments, questions and requests for more information will be received for 60 days, ending on March 15, 2019. Please direct your written comments to:

All Agricultural Herbicide & Acetochlor BMPs Adopted

The MDA adopted the revised voluntary Best Management Practices for All Agricultural Herbicides and for Acetochlor. These BMPs were originally drafted in 2004, revised in 2010 and revised again after a public review process in 2018. The revisions were made in collaboration with the University of Minnesota Extension and other interested parties.

The purpose of these BMPs is to protect Minnesota's groundwater and surface water from potential herbicide contamination resulting from normal agricultural use. These voluntary BMPs should be adopted when applying all agricultural herbicides including acetochlor in Minnesota.
