What signal word is used on pesticide labels for products categorized as slightly toxic?

The signal word used on pesticide labels for products categorized as slightly toxic is "Caution." This term indicates that the product has a lower potential for causing harm compared to those labeled with "Warning" or "Danger."

Pesticide labels are designed to communicate the level of toxicity and the necessary precautions for safe handling and application. "Caution" serves as an important signal for users to handle the product carefully, while understanding that it poses some level of risk, albeit not as severe as those labeled with stronger warnings like "Danger," which signifies high toxicity, or "Warning," which indicates moderate toxicity.

"Notice" is not typically used as a signal word on pesticide labels and does not convey toxicity levels. Hence, "Caution" is the appropriate term for slightly toxic products, helping users to make informed decisions for safe use.
