What signal word must all slightly toxic pesticide labels carry?

1. Danger

2. Caution

3. Warning

4. Hazard

The correct answer is: Caution

The term "Caution" is the signal word that must be carried on the labels of pesticides classified as slightly toxic. This classification indicates a level of toxicity that is relatively low compared to other categories. The use of "Caution" serves as a guideline to inform users that while the pesticide can still be harmful, the risk associated with its use is manageable with appropriate safety practices. In the broader context of pesticide regulation, signal words are important because they convey essential safety information at a glance. Each signal word corresponds to a specific range of toxicity. For example, "Danger" typically indicates a highly toxic substance that can cause serious injury or death, while "Warning" is reserved for moderately toxic materials. Therefore, "Caution" provides an essential framework for understanding and mitigating risk appropriately.
