Who is responsible for ensuring a restricted-use pesticide is used according to label directions?

• A. The pesticide manufacturer only
• B. The weather service
• C. The applicator or supervisor
• D. The landowner only

Answer: (C)

Pesticide labels are legal requirements that spell out exactly how to apply a restricted-use product. The person who actually performs the application, or the supervisor overseeing that work, is responsible for making sure every use follows the label. This means using the correct site, rate, timing, required personal protective equipment, mixing procedures, equipment, and any precautions like restricted-entry intervals or posting. The label sets the standard for safe and legal use, and those in charge of applying the product must ensure compliance. The manufacturer provides the directions, but does not enforce field practices; the weather service doesn’t govern how the product is used; and the landowner is responsible only if they are the one applying or supervising the work.
