Which category of pesticides is indicated by the signal word 'Caution'?

The signal word 'Caution' is associated with Category 3 pesticides, which are classified as having a low level of toxicity. These pesticides are considered less hazardous compared to those in Categories 1 and 2, which either indicate a high level of toxicity or are more harmful to humans and the environment. The label reflects the potential risk, guiding users in handling and applying these substances with appropriate care.

In contrast, Category 4 pesticides are the least toxic and are often marked with the signal word 'Warning' or may not have a signal word at all. The distinction among these categories is essential for users to understand the level of risk involved when using these chemicals. By identifying the correct category, users can make informed decisions regarding safety precautions and application methods.
