What is a signal word on a pesticide label?

A signal word on a pesticide label is indeed a term that indicates the level of toxicity of the product. It serves as an important safety measure to inform users about the potential hazards associated with handling and applying the pesticide. Common signal words found on labels include "Caution," "Warning," and "Danger," each reflecting different degrees of toxicity.

These words help users quickly assess the risks involved and understand the necessary precautions they need to take to ensure safe handling and application. Understanding signal words is crucial for responsible pesticide use and ensuring the safety of both applicators and the environment.

The other options do not accurately describe the purpose or function of signal words, as they refer to different aspects of pesticide labeling that do not relate to toxicity.
