What signal word must be on the label for pesticides classified as "Relatively non-toxic"?

Pesticides classified as "Relatively non-toxic" must display "Caution!" as the signal word on their labels. This indicates that while the product poses a lower risk than others, it may still present some hazards if not handled correctly. The use of "Caution!" serves to alert users to handle the product with care, ensuring they are aware of its potential effects, even if those effects are not as severe as those indicated by terms like "Warning!" or "Danger!" These terms reflect higher levels of toxicity, thus differentiating the relative safety of products within the pesticide classification system. Proper labeling is crucial for safety and compliance, guiding the safe use and application of pesticides by providing essential information on their handling and risks.
