Private Pesticide Applicator Training in Columbia County

(Last updated 9/3/20)







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 County.  If you do not attend a session and need to be certified, a Self-Study Test Only session is usually held in February or you can contact your County UW-Extension Office.  Arrangements may be made to take the exam on an individual basis.  The fee is payable when you pick up your materials.  Please pick up the materials prior to the training or test.

The training fee is $30.00, which includes training materials and certification for five years.  Some sites may have an extra fee of $10 to cover catered lunch costs (trainings only).
