During an onsite pesticide operation, who is primarily responsible for ensuring that all label directions are followed?

• A. The equipment vendor.
• B. The pesticide retailer.
• C. The applicator.
• D. The Qualified Supervisor.

Answer: (D)

The person in charge on the job site is responsible for making sure every label instruction is followed. The Qualified Supervisor has the authority and duty to ensure that all label requirements—such as proper product selection, exact rates, mixing and loading procedures, timing, restricted-entry intervals, PPE, drift prevention, weather considerations, and safety precautions—are understood and followed by everyone involved. They provide the necessary training and supervision, stepping in if anything on the label isn’t being observed. The person applying the pesticide carries out the work according to the label, but do so under the supervisor’s oversight. Vendors and retailers do not manage day-to-day on-site compliance with the label directions.
