Which laws are violated if pesticides are used inconsistently with label directions?

Using pesticides inconsistently with label directions violates both federal and state laws because the pesticide label is considered a legal document that includes instructions for safe and effective use. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), it is illegal to use a pesticide in a manner inconsistent with its labeling. This federal law applies across all states and territories.

Additionally, many states have their own regulations that reinforce or expand upon federal guidelines, holding applicators to high safety and environmental standards. Therefore, failure to adhere to label directions could result in civil or criminal penalties under both federal and state laws, emphasizing the importance of compliance for legal and safety reasons.

Using pesticides "carefully" does not exempt someone from following label directions; the context and specific instructions on a pesticide label are vital for ensuring the safety of humans, animals, and the environment.
