Underground Storage TanksAgricultural Pesticide Use in Vermont
In the 2019 federal survey estimates, Vermont's most-applied agricultural pesticides statewide were Glyphosate, Metolachlor & Metolachlor-S and Atrazine. 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.
Pesticide data: USGS NAWQA Pesticide National Synthesis Project (EPest county-level use estimates). Latest available county estimates: 2019.
