Core courses cover basic pesticide safety topics. Credits from these can be used by all certified applicators for their recertification.

Category courses contain information for specific certification categories such as Private vegetable farmers or Commercial Ag and Plant applicators. You need to be sure your certification category is included in the list of approved categories for these courses.

These courses adhere to New York State regulations (6 NYCRR 325.18) and have been approved by the New York State Department of Environmental Conservation. When taking an on-line recertification course, the following apply:

  1. We will check the amount of time spent in the course(s) before sending your official certificate. If you complete the course in under the required time, you forfeit your purchase and will not receive credits. 
  2. The applicator earning credits must be the one taking and completing the course. Anyone using a substitute course taker is committing fraud and will forfeit their course fee and will not receive credits. 
  3. A particular course may not be repeated in a recertification cycle. 
  4. There are no limits on the number of different courses you can select.
  5. You can only take a maximum of 7 hours of training per day.
