This page provides information for certification of private pesticide applicators in Kentucky.

A certified private pesticide applicator can use Restricted Use pesticides to produce any agricultural commodity on property owned or rented by him (her) or an employer, or to the lands of a farmer-neighbor, if the application is made without compensation other than trading of personal services between producers of agricultural commodities. Certified private applicators also may train workers to satisfy Worker Protection Standards

Private applicator certification is valid for 3 years and expires on December 31 of the final year. Applicators must go through the county training porgram to keep their certification in effect.

Basic Information

Your PATIM database should be sent in after each training session. If you have several in a short time it is fine to wait until they are done and then send the file. We keep the most current file for you county so it can be used as a backup if yours is lost or damaged. The names are added to a master list that goes to the KDA, and a list is posted so that dealers can get certification numbers for their records. We no longer give lists of private applicators to dealers without an open records request. However, the lists are posted on the internet so everyone has equal access. The county lists are available under the Certified Private Applicator List tab.
