Why is it important to not alter or use a pesticide label in a way not approved by the label?

• A. Altering or misusing a label can violate state and federal law and create health and environmental risks.
• B. Label alterations are allowed if it helps farmers.
• C. The label is only a guideline.
• D. Only the manufacturer can alter labels.

Answer: (C)

Pesticide labels are legal instructions that tell exactly how a product may be used. Following the label ensures proper pest control while protecting people, property, and the environment. When a label isn’t followed or is altered, it can violate state and federal law and create health and environmental risks. The label specifies what crops or sites you can treat, which pests are controlled, the correct application rate, timing, buffer zones, worker protection, disposal, and any restricted-use requirements. If you modify those directions or use the product in a way not approved, residues, runoff, or exposure can occur that weren’t planned for, potentially harming people, wildlife, water sources, or beneficial organisms.

The other ideas misstate how labels work. The label isn’t just a guideline to be adapted as you see fit, and only the manufacturer isn’t the authority to change it—changes must go through the proper regulatory processes so they’re evaluated for safety and legality.
