The Michigan Department of Agriculture and Rural Development (MDARD), in conjunction with Michigan State University Extension, will be offering in-person pesticide applicator testing and core review on April 30, 2024, at Caledonia Township Hall, 135 N State Rd., Owosso, MI 48867. Parking is available at the Caledonia Township Hall. You can register online at MDARD In-Person Core Testing and Core Review or call the Shiawassee County Michigan State University Extension office at 989-743-2251 for the core review and test.

We recommend participants read and study the core manual before attending the review. Core manual copies may be ordered from the National Pesticide Safety Education Center.

Test day

Registration starts at 8:30 a.m. on April 30. Participants are encouraged to register online prior to the event due to limited space. Walk-ins will be accepted until the capacity of the room allows. If registering online, participants will be able to pay with a credit card. Walk-ins must pay with exact cash or a check payable to Michigan State University.

Local Michigan State University Extension educators Teresa Crook and Salta Mambetova will lead the mandatory four-hour review from 8:30 a.m. to 12:30 p.m. The review covers all the chapters in the National Pesticide Applicators Certification Core Manual. A light lunch will be provided after the review. MDARD will start testing approximately at 1 p.m. 


There are two separate fees for the mandatory core review and the applicator testing. The cost of the review is $15. Payment can be made online at registration, with exact cash at the day of the event, or by check payable to Michigan State University.

The fee for applicator testing varies by the certification and is not collected on the day of the testing but mailed to MDARD after your core test is passed. The private applicator certification fee is $50, the commercial applicator certification fee is $75 and the registered applicator certification fee is $45. Only checks payable to State of Michigan are acceptable payments. Postage paid envelops will be provided to send certification payment to MDARD at the event. Cash or credit card payments are not accepted. Private applicator fees can be waived for Military Veterans if a copy of their DD214 is provided.
