Which signal word indicates a pesticide is slightly toxic or less?

The signal word that indicates a pesticide is slightly toxic or less is "Caution." In the context of pesticide labeling, signal words are used to inform users about the level of toxicity associated with the product. "Caution" specifically indicates that the product poses a low toxicity risk and is generally considered safe to handle with appropriate precautions. This signal word is often found on products that require certain safety measures but do not pose a significant danger if used according to the label instructions.

In contrast, "Danger" denotes a highly toxic or corrosive substance that can cause serious harm or death upon exposure. "Warning" implies a moderate level of toxicity that might still necessitate careful handling but not to the extent of a product labeled with "Danger." "Alert" is not a standard term used in pesticide signaling and does not have an established toxicity meaning. Understanding these distinctions helps ensure safe handling and proper use of pesticides, minimizing the risk of harm to humans, animals, and the environment.
