Which of the following is TRUE of a product's EPA registration?

• A. It is optional for use in salons.
• B. It guarantees the product's effectiveness.
• C. It is against Federal law to use the product contrary to label.
• D. It remains valid indefinitely.

Answer: (C)

A product’s EPA registration indicates that it has been evaluated and approved by the Environmental Protection Agency for safety and effectiveness when used according to the label instructions. This means that it is illegal to use a registered product in a manner that is inconsistent with the label. The product must be applied, stored, and disposed of according to the guidelines set forth by the EPA, ensuring both safety for the user and compliance with federal law.

The registration does not guarantee overall effectiveness of the product in all situations or against all pests, and while it is important for regulatory reasons, it does not confer an indefinite period of validity. Furthermore, EPA registration is a requirement for products intended for use as pesticides, making it a necessity rather than an option.
