Agricultural Pesticide Use in Minnesota

In the 2019 federal survey estimates, Minnesota's most-applied agricultural pesticides statewide were Glyphosate, Acetochlor and Metolachlor & Metolachlor-S. These estimates describe agricultural land use across the state — context for what's in use around the region, not a reading on any garden's soil.
