If a pesticide label includes the word "WARNING," what does it convey?

A pesticide label that includes the word "WARNING" indicates that the pesticide is moderately toxic. In the context of pesticide labeling, toxicity levels are classified to communicate the potential risk to humans and the environment. The signal words used on pesticide labels—such as "DANGER," "WARNING," and "CAUTION"—represent specific toxicity levels.

"WARNING" on a label designates a moderate level of toxicity, meaning that while the pesticide poses a potential risk, it is not as severe as products labeled with "DANGER," which indicates high toxicity. Conversely, the lower level of toxicity, represented by "CAUTION," corresponds to products that are slightly toxic. A label marked with "WARNING" effectively conveys a significant but manageable degree of caution necessary when handling the product, reflecting the need for proper safety practices to minimize risk of exposure. Pesticides that have no toxicity would typically not be classified under any of these categories, as they do not pose a risk that necessitates caution.
