NEW All Agricultural Herbicide & Acetochlor BMPs Open for Public Comment

The MDA is seeking input on the following two revised BMP documents. These BMPs were drafted in 2004, revised in 2010, and recently revised again. The revisions proposed below 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. The MDA requests comments on the following two documents:

  1. Revised Water Quality Best Management Practices for All Agricultural Herbicides (PDF)
  2. Revised Water Quality Best Management Practices for Acetochlor (PDF)

Comments may be submitted August 6 - October 4, 2018. Comments must be submitted by 4:30 p.m. on October 4th, 2018.

Please submit comments and questions by email to:
