A map of Missouri shows dicamba injury spreading across the state.

The Missouri Department of Agriculture tracks dicamba complaints not only by the numbers, but also by location. This year, dicamba complaints are found in the northeastern corner of the state, along with the western edge. While the numbers of complaints per acre appear low, the map does not tell the total number of impacted acres per county. Still, farmers can see that dicamba drift is not just a southeast Missouri problem.

As of July 30, there were 239 total pesticide use complaints, with 174 allegedly caused by dicamba drift. Southeast Missouri accounts for 85 of those complaints, leaving the remainder to areas north and west of the Bootheel. Of the total pesticide use complaints, 16 were from 2,4-D, leaving 49 from pesticides other than dicamba or 2,4-D.

This map from the Missouri Department of Agriculture shows dicamba damage across the state in 2018.
