If you or your employees purchase, mix, or apply “Restricted Use” pesticides on property you own or operate in Wisconsin, you MUST be certified to do so. Certification is valid for 5 years.

The 2020 Walworth County Pesticide Applicator Training and testing session coming soon

Walworth County Government Center

100 W Walworth St Room 214

Elkhorn, WI 53121

Applicators can also do the self-study option by purchasing a manual from a UW-Extension office and scheduling a test with that office. The fee for the training and license is $30 and includes the book. We recommend a week between paying the fee and taking the test. You must have a score of 70% or better to pass. Applicators may also visit other counties in Wisconsin for their trainings. Visit http://ipcm.wisc.edu/pat/ for dates and locations.
