Which part of the pesticide label shows you the toxicity of the pesticide?

• A. The signal word
• B. The net weight
• C. The batch number
• D. The manufacturer address

Answer: (A)

Toxicity information on a pesticide label is conveyed by the signal word. This single word quickly communicates how dangerous the product is to people who handle or are exposed to it, guiding what protective gear to wear and what precautions to take. Typical signal words indicate increasing levels of danger: caution for slightly toxic, warning for moderately toxic, and danger (or poison on older labels) for highly toxic. The other label parts—net weight tells you how much product is in the container, batch number helps identify a production lot, and the manufacturer address provides contact information—none of these convey how toxic the product is.
