castor oil Passed The EPA has created a pesticide classification called: "Minimum Risk Pesticides." These pesticides have products for use as herbicides, fungicides, insecticides, and repellants.  All of the products that meet the EPA requirements for minimum risk pass Thurston County's review criteria. 

The data that is normally required for pesticide ingredient registration is waived for all pesticides that meet the requirements of a 25B minimum risk pesticide. The requirements include that all active ingredients are from the 25b list, and that all other ingredients are from the EPA's most current List 4A (Minimum Risk Inert Ingredients).

Thurston County considers these pesticide ingredients low in hazard, however, they can still cause injury.  Many of the minimum risk products can cause mild to severe skin and eye irritation - so follow all label directions.
