Private applicator certificates allow the grower to apply pesticides on his/her own property only. In San Diego, the tests are given monthly by the County Ag Commissioner's (CAC) office. UC Cooperative Extension does not give the tests but we do provide the study guide in English and Spanish which you can pick up at our office 9335 Hazard Way, Suite 201, San Diego, CA 92123 or you can order online.
Contact the CAC is you have any other questions.
