The word 'Caution' on pesticide labeling indicates:

• A. High toxicity
• B. Moderate toxicity
• C. Low toxicity
• D. No toxicity

Answer: (C)

Pesticide label signal words communicate how toxic the product is in acute exposure. Caution is the lowest level among the common signal words, indicating relatively low acute toxicity. This designation comes from regulatory toxicity categories based on LD50 tests, so a product labeled with Caution has a smaller immediate hazard than those labeled Warning or Danger. But it doesn’t mean there’s no risk at all—the label still requires following all safety directions and using any required PPE. High toxicity would be marked with Danger (and sometimes Poison), moderate toxicity with Warning, and “no toxicity” isn’t a standard label word used for hazardous products.
