The use of pesticides in general requires basic knowledge in their safe and efficient management. For use of restricted-use pesticides (RUPs), in particular, it is required that the user be a Certified Pesticide Applicator (CPA), or be directly supervised by a CPA.

The Pesticides Control Act defines an RUP as a pesticide which, "if used in accordance with a widespread and commonly recognized practice, may generally cause, without additional regulatory action, unreasonable adverse effects on the environment, including injury to the applicator". Of the 300+ pesticides currently registered for use, less than 40 are classified as RUPs (Click here for list).

In 1996, after eight years of informal training of pesticides users, the Board launched the National Pesticide Certification Program to provide for the training and certification of pesticide users in pesticide management. A four-year grace period provided all pesticide users the opportunity to seek certification, with full enforcement of the Certified User Regulations commencing on 1 April 2000.

Note: Only a certified pesticide applicator is authorized to purchase and use restricted-use pesticides!
