What does the signal word "Caution" on a pesticide label indicate?

The signal word "Caution" on a pesticide label is a crucial indicator of the product's toxicity levels. When this word is displayed, it signifies that the pesticide has a moderate level of toxicity to humans and the environment. It is a warning meant to inform users that certain precautions should be taken when handling the product, as it can pose health risks if exposure occurs.

Understanding toxicity levels is essential for safe handling and application of pesticides. In contrast, other signal words indicate different toxicity levels; for instance, "Warning" typically signifies moderate toxicity, while "Danger" points to high toxicity. "No toxicity" would not be indicated on a pesticide label since it would not necessitate a caution signal. By recognizing the meaning behind "Caution," users can make informed decisions about how to safely use the pesticide and protect themselves and others while applying it.
