OSU Extension Wayne County has set up testing dates with the Ohio Department of Agriculture (ODA) to allow private and commercial applicators to obtain a pesticide applicators license. To obtain a license, applicators must take and pass a core exam plus one or more specific category exam(s). The cost of a private applicator license is $30 and a commercial applicator license is $35.  ODA personnel administer the tests and all testing will take place in Fisher Auditorium at OARDC from 1:00 pm until 4:00 pm on the following dates:

  • Wednesday December 20, 2017 in the Fisher Auditorium conference room
  • Tuesday, January 16, 2018 in the Fisher Auditorium conference room
  • Thursday, February 15, 2018 in the north exhibit area, Fisher Auditorium
  • Tuesday, March 13, 2018 in the Fisher Auditorium conference room
  • Wednesday, April 18, 2018 in the Fisher Auditorium conference room

There are a limited amount of spaces available for each testing session. Once the spaces are filled, the testing session is closed. Register to reserve a spot online at  or by phone to the ODA Pesticide Division at (800) 282-1955, ext. 31.

Anyone taking an exam will be required to show photo identification or some form of identification.

Private applicators are encouraged to obtain study materials from the Wayne County Extension office before taking the exam. Our office tries to keep copies of some of the more commonly needed study materials on hand, but in some cases it may be necessary to order study materials. Plan ahead; it will take 7-14 days for ordered materials to arrive. In addition, some study materials are available on-line.  More information about study materials for private pesticide applicators is available on-line at .

Persons testing for a commercial applicator license should also obtain study materials before the exam date. Study materials are sent by mail from the Ohio Department of Agriculture when an application for a commercial pesticide license is made. More information about the commercial license procedure is available on-line at .
