On a pesticide label, what must the applicant do if the label prohibits certain water body uses or access?

• A. Do not apply or access the site for that use; follow all label water-use restrictions and site-specific instructions.
• B. Apply anyway if other sources are available.
• C. Only apply during night hours.
• D. Seek a waiver from the label restrictions.

Answer: (A)

Pesticide labels are binding rules about how a product may be used. When a label clearly prohibits certain water body uses or access, you must not perform those uses or enter the site for that purpose. You are required to follow all water-use restrictions and any site-specific instructions exactly as written. This protects people, aquatic life, and water quality, and helps ensure the product is used safely and legally.

Choosing to apply anyway ignores the explicit restrictions and is not acceptable. Using the product at night does not override a water-use prohibition, since the restriction applies regardless of time. Seeking a waiver from the label isn’t an option—the label sets the required terms, and any deviation isn’t permitted. If the restrictions don’t fit your situation, you should select a different product or method that complies with the label.
