Pesticide Applicator Training in Columbia County

(Last updated 11/12/21)






All private farmers who apply restricted use pesticides must be certified once every five (5) years.  The training is a cooperative effort by UW-Extension, DATCP, and local Co-Ops and suppliers.  Training sessions are usually offered in January, February or March of each year in Columbia & surrounding counties.

There are several certification options listed below.  Please contact the Columbia County Extension office to register for the Columbia County session.  The in-person training fee of $40 is only payable with cash or check when you pick up your materials. The Zoom or self-study on-line trainings are $30.  Please note that we have attendance limits at each location and occasionally a session is cancelled due to lack of registrations.  You will be notified if there is any change in your chosen session.

PAT Manuals are available at the Columbia County Extension Office, 112 E. Edgewater St., Rm. 212, Portage, WI or online at  You are encouraged to purchase and review the manual before you attend a training session.  The exam is based on both the manual and the training program.  If you are unable to attend one of the sessions, you may schedule a time to take the self-study exam at the Extension office, exam times are limited.  Registrations must be received by the registration date for each session.
