What does the term “signal word” on a pesticide label indicate?

The term "signal word" on a pesticide label is crucial for understanding the potential risks associated with the product. It indicates the level of toxicity of the pesticide, using specific words such as "caution," "warning," or "danger." Each of these words provides information about the severity of the toxicity and the precautions that should be taken when handling or applying the pesticide.
