Pesticide Applicator Training

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 has been scheduled:

Thursday, February 6, 2020

Walworth County Government Center

100 W Walworth St Room 214

Elkhorn, WI 53121


9:00 AM: Registration

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 for dates and locations.
