2021 Private Pesticide Applicator Recertification

Due to COVID-19, the deadline for pesticide applicator recertification has been extended for 2021. Private applicators whose certification was set to expire on 3/31/21 now have until 7/1/21 to recertify. If you prefer to recertify in person, you can schedule an appointment to recertify at the Madison County Office in London on a one-on-one basis (If you are in another county, contact your county Extension Office for information about how they are handling in-person recertification).

Study Materials

Each private applicator will need to take the Core test (general safety for the applicator and the environment) and the category(ies) that correspond to the crops he/she grows. For example, an applicator who grows corn and soybeans will need to take the Core and Category 1 exam. An exam is only required for category 7 if applicator does NOT hold one or more categories on their license (1-6).  Category 7, Specialty Uses is included in categories 1-6.  

NOTE: Please be sure to call your local OSU Extension office before stopping by. This allows the office to make sure they have the materials on hand for when you stop in. Some offices may have to order materials, which can take 2-3 weeks time. Thank you!
