Which statement about federal pesticide regulation is true?

The statement indicating that approved pesticide labels have the force of law is accurate because pesticide labels are legally binding documents. When a pesticide is registered for use, the accompanying label outlines specific instructions, safety precautions, and limitations regarding its application. This regulatory framework is designed to ensure the safe and effective use of pesticides while protecting human health and the environment. Ignoring or deviating from the instructions on the label could lead to misuse, potential harm, and legal repercussions, as adherence to these labels is enforced by federal law.

In contrast, the other statements suggest practices that contradict regulatory standards and safety protocols. Using pesticides without regard to label instructions undermines the intention of safe pesticide application. Labels are not merely suggestions; they are mandatory guidelines essential for ensuring safety and compliance with the law. Furthermore, modifying pesticide labels without authorization is illegal and can result in significant consequences, as it misrepresents the product's approved uses and can lead to serious health and environmental risks.
