What could happen if a pesticide is applied to a site not specified on its label?

• A. It could improve pest control.
• B. It would be illegal and unsafe.
• C. It would have no consequences.
• D. It would extend the REI.

Answer: (B)

Pesticide labels are legal instructions that specify where you may apply a product, at what rate, and under what conditions. Applying to a site not listed on the label means you’re using the product outside its approved uses, which is illegal and can be unsafe for people, pets, crops, aquatic life, and other non-targets. Because the label is the rule for use, misapplying it can lead to regulatory action and liability, and it may cause unintended harm or ineffective pest control. The idea that it could improve control is not reliable, and there would be real consequences. The option about extending the restricted-entry interval isn’t correct because REIs are set by the label and aren’t extended by applying to an unlisted site.
