What signal word is required for slightly toxic pesticides?

The correct signal word for slightly toxic pesticides is "WARNING." This term indicates that the pesticide poses a moderate hazard and should be handled with care.

Each signal word serves a specific purpose in communicating the level of toxicity associated with a pesticide. "DANGER" is used for highly toxic substances, where even a small exposure could cause serious harm or death. "CAUTION" is reserved for those products that have a low toxicity and can generally be handled without significant risk. "POISON" is a designation associated with toxic substances that may cause immediate effects. In contrast, "WARNING" clearly caters to "slightly toxic" pesticides, providing a middle ground that signals the need for precaution and appropriate handling without instilling an excessive level of fear.
