What does the signal word "CAUTION" indicate about a pesticide's toxicity?

The signal word "CAUTION" on a pesticide label indicates that the product falls under Category III, which denotes a relatively low level of toxicity. In general, signal words are a quick visual cue used to communicate the inherent risk associated with the pesticide. "Caution" suggests that the substance can still be harmful or pose risks if not handled correctly, but it is less toxic compared to products labeled with "WARNING" or "DANGER," which indicate higher toxicity levels.

Pesticides categorized as Category III typically require basic safety measures during application but do not demand the stringent precautions needed for more toxic categories. As such, understanding signal words and the categories they represent helps users make informed decisions regarding the safe handling and application of pesticides.
