The Wisconsin Custom Operators will host commercial pesticide applicator training and testing Feb. 18 in conjunction with the Forage Symposium at Chula Vista resort in Wisconsin Dells. Many custom operators are required to have a commercial pesticide applicator’s license to handle products like nitrogen stabilizers and forage and silage inoculants. Owners, crew leaders and employees from the custom farming industry are encouraged to attend.

The commercial pesticide applicator training also qualifies as continuing education towards the WCO Safety Certification program, now in its fifth year.

The training will be instructed by staff from the UW Department of Agronomy and the exam will be proctored by the Wisconsin Department of Agriculture, Trade and Consumer Protection. A field and vegetable training will be offered, which is the same as the open training sessions that are offered throughout the state. This certification category is broad yet is what individuals who treat manure or apply inoculants are required to have.
