Significant updates to the Missouri Pesticide Use Act take effect on January 1, 2025, bringing changes that affect Private Pesticide Applicators who use Restricted Use Pesticides (RUPs). The Missouri Department of Agriculture has introduced new certification requirements and licensing regulations to ensure proper handling and application of pesticides.
New Certification Categories
Private Pesticide Certification is now classified under Category 20, with additional categories introduced:
- Category 21 – Soil Fumigation
- Category 22 – Non-soil Fumigation
- Category 23 – Aerial Application
For example, growers who apply grain fumigants will need Category 20 certification but must also obtain certification in Category 22 to purchase and apply grain fumigants legally.
Supervision Rules Have Changed
Previously, Private Applicators could supervise employees using RUPs. Under the new regulations, this is no longer permitted. If a grower has employees mixing, loading, spraying, cleaning equipment, storing, or disposing of pesticide containers involving RUPs, those employees must now obtain a Category 20 Private Pesticide Certified License to continue those activities legally.
Certified Provisional Private Applicator License
A new Certified Provisional Private Applicator License has been introduced for individuals 16 or 17 years old who are immediate family members of a certified Private Applicator. Upon turning 18, these individuals will automatically become Private Pesticide Certified Applicators.
License Expiration and Renewal
If a Private Pesticide License has not yet expired, the holder may continue using Restricted Use Pesticides until the expiration date. However, recertification under the new laws will be required upon expiration. Licenses will continue to be valid for five years.
