Private Pesticide Applicator


Current pesticide applicator certifications were extended until December 31, 2021. If your certifications expired between January 31, 2020-November 30, 2021, they were extended to December 31, 2021. 

If you have a temporary certification number ending with "T" you will not need to purchase additional training material from UW PAT to test in person; the training material purchased for your temporary certification will be honored for your in-person testing.

The online UW PAT training you took qualifies you for the 50% passing score when testing in-person at a UW-Madison Divison of Extension office. Your county Extension office will determine when they are able to offer an in-person private applicator certification exam based upon current restrictions.​


Private applicators are people who apply restricted-use pesticides to their own or their employer's agricultural crops. In addition to farm crops, this includes Christmas trees, forests, and nursery and greenhouse plants. 

Private applicators must be certified, but do not need a license. 

Steps to certification

  • Buy a training manual at your county University of Wisconsin-Division of Extension office.
  • Schedule an exam time with your county UW-Division of Extension office.
  • Pass an open-book exam.​
  • The UW-PAT Program will be providing online General Farm training for 2021. You may elect to take the online training or attend a training hosted by your County Extension Agent.

Certification is valid for five years. There are six categories for certification. You may be certified in more than one category.​​​
