The herbicide label is a legal document and is your best source of information about the product and where it should or should not be used.

• A. Optional guidance
• B. True
• C. False
• D. Only for interstate use

Answer: (B)

Pesticide labels are legal documents that set enforceable instructions for using a product. Because the label carries the authority of the product’s use under FIFRA, it is the best source for exactly where and how the herbicide can be applied. It clearly lists the crops or sites that are allowed, the pests it targets, the proper application rate and timing, any mixing or tank-mixing restrictions, and important safety requirements such as PPE and restricted-entry intervals. It also outlines environmental precautions, drift and buffer-zone considerations, as well as storage and disposal rules. Following the label protects health, the environment, and you legally. That’s why this statement is true. Optional guidance would be misleading because the label isn’t optional; it’s mandatory. It isn’t false, and it isn’t limited to interstate use—the label governs all labeled uses, whether within a state or across state lines.
