Missouri Pesticide Use Act changes coming  

Changes to the Missouri Pesticide Use Act (MPUA) will take effect Jan. 1, 2025, impacting all pesticide applicators, including certified private applicators and pesticide dealers.

Existing certified applicators will have a “delayed” certification requirement for six new categories until their current certifications expire, allowing them to continue operating under previous regulations. However, beginning Jan. 1, certified private applicators will no longer be able to supervise the use of restricted use pesticides (RUPs), and all RUP applications must be performed by certified applicators.

Pesticide dealers will still be able to sell RUPs to certified applicators with delayed licenses until those licenses expire, but individuals will no longer be able to hold more than one Pesticide Dealer license.

New regulations stipulate that dealers can only distribute RUPs to other licensed dealers or certified applicators with valid certification in the appropriate category.
