What signal word indicates a relatively nontoxic pesticide?

The signal word "Caution!" is used to indicate a relatively nontoxic pesticide. In the context of pesticide labeling, signal words are important indicators of the level of toxicity associated with a product. "Caution!" suggests that the pesticide poses a lower level of risk to humans and the environment compared to products labeled with "Warning!" or "Danger!" which indicate greater toxicity.

Pesticides are categorized based on their potential hazards, and the signal words are placed on the labels to help users assess the risks associated with handling the product. "Caution!" alerts users that while the pesticide may still require careful handling and application, it is generally safer than those classified with stronger signal words. Thus, understanding this classification helps ensure safe usage practices among applicators and consumers.
