What do signal words on labels indicate?

• A. Indicate approximately how toxic the pesticide product is
• B. Indicate the target pest species
• C. Indicate the storage guidelines
• D. Indicate the label revision date

Answer: (B)

Signal words indicate how hazardous the product is to humans and animals, guiding safe handling, application, and protective measures. They appear as terms like Danger, Warning, or Caution and tell you the level of acute toxicity and the precautions you must take, such as what PPE to wear and any re-entry restrictions. They do not tell you which pests the product targets—that information is located in the use directions and target pest sections of the label. They also aren’t the place to find storage guidelines or the label’s revision date, which appear in other parts of the label. In aquatic contexts, understanding these warnings helps protect people and non-target aquatic life during use.
