Agricultural Pesticide Use in Florida

In the 2019 federal survey estimates, Florida's most-applied agricultural pesticides statewide were Glyphosate, 2,4-D and Chlorpyrifos. 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.
