Pesticide and fertilizer applicator certification is required

By Wayne Dellinger - OSU Extension

MARYSVILLE — Some farmers purchase and use restricted-use pesticide products on their growing crops to control weeds and insects. To purchase restricted-use pesticides, farmers must be trained and licensed in proper application methods. There are approximately 200 farmers in Union County licensed to purchase and apply restricted-use agricultural pesticides for private use (non-commercial). Each farmer is required to obtain three hours of continuing education every three years or take a written examination to maintain a valid license.

Agricultural fertilizer applicator certification is now required for farmers who apply fertilizer to more than 50 acres of agricultural production grown primarily for sale. This requirement was signed into law in June 2014, and also requires certification for commercial agricultural fertilizer applicators. Applicators who met the criteria for the fertilizer certification were required to attend training by Sept. 30, 2017. Farmers who have their fertilizer applied by co-ops or custom applicators are not required to be certified. A limited number of three hour courses are available around the state for those who have not yet been certified. Please register online at

Farmers and commercial applicators needed to attend a training course offered by Ohio State University Extension to become certified. Those who have a pesticide applicator license needed to attend a two-hour fertilizer certification. If an applicator did not have a pesticide license, they were required to attend a three-hour fertilizer certification. A one hour recertification course is now required every three years to keep this certification current. The particular year of recertification of pesticide applicators that also hold fertilizer applicator certification were synched to be the same year (based on pesticide applicator recertification year).

Pesticide Recertification and one-hour Fertilizer Applicator Recertification opportunities for farmers are available in Union County at 9 a.m. on Friday, Feb. 23 at Evolution Ag on U.S. Route 42. Register online at or in person at the Union County Extension Office or Evolution Ag. With limited seating capacity at most locations, pre-registration is highly encouraged. For those needing recertification this year, watch your mailbox for additional information from Ohio State University Extension and Ohio Department of Agriculture.

New information available at the Union County Extension Office includes the 2018 Weed Control Guide, the newly revised Ohio Agronomy Guide, the 2018 Midwest Vegetable Production Guide for Commercial Growers, the Ohio Christmas Tree Producers Manual, the Top of Ohio Ag and Natural Resources Newsletter (lists all programs in the area, including Union County), the Ohio State University 2017 Corn, Soybean, and Forage Performance Trials, and brochures for the 2018 Conservation Tillage and Technology Conference to be held March 6-7 in Ada.
