What responsibilities does a certified applicator have regarding their assistants?

• A. They are personally responsible for any misapplication carried out by their assistants.
• B. They must supervise only during the initial application.
• C. They are not responsible for assistants' errors.
• D. They can delegate responsibility entirely to the assistant.

Answer: (A)

Accountability for assistants rests with the certified applicator. In Alberta’s pesticide rules, the certified applicator must supervise anyone assisting with an application and ensure they follow label directions, safety practices, and proper procedures. Because the applicator is responsible for the work conducted under their supervision, they are personally accountable for any misapplication carried out by their assistants. This duty to supervise applies to the entire application process, not just the first moment of spraying, and it means you cannot simply delegate all responsibility away. If an assistant errs, the certified applicator bears the liability, so training, clear directions, and ongoing oversight are essential.
