This guide lists approved pesticides for industrial hemp production in Missouri. Approved pesticides have received U.S. Environmental Protection Agency (EPA) approval and are registered for use by the Missouri Department of Agriculture. Information for approved pesticides can be found in Table 1. All information is current as of Nov. 10, 2020. Hemp buyers may have additional restrictions. Growers should confirm pesticide approval from contracted buyer to guarantee acceptance at harvest.

Be aware if industrial hemp is grown in rotation with conventional crops, there is potential for residual herbicide contamination. Some herbicides can carryover for multiple years following their use in a given area making previous knowledge of land usage and treatment a necessity before planting a hemp crop. Further information about herbicide carryover considerations in hemp can be obtained at https://www.wiscweeds.info/post/herbicide-rotation-restrictions-before-planting-industrial-hemp.
