What is the consequence of applying a pesticide at a rate higher than the label rate?

Applying a pesticide at a rate higher than the label rate is classified as illegal primarily because it violates federal and state regulations governing pesticide use. The label on a pesticide not only indicates the correct application rate but also provides crucial instructions for safe and effective use, including environmental and health risk assessments. Exceeding these specified rates can lead to increased risks of damage to non-target organisms, potential environmental harm, and pose health risks to humans and wildlife.

Pesticide regulation is designed to promote responsible usage, ensuring safety for applicators, consumers, and the environment. Therefore, adherence to label rates is essential to comply with legal requirements and to prevent adverse consequences that could result from over-application, such as pesticide resistance, residue issues, and harm to beneficial species.
