The "signal word" on a pesticide label is a critical indicator of the product's level of toxicity. It is intended to provide users with a quick reference to understand how harmful the pesticide may be if ingested, inhaled, or contacted with skin. These signal words, which can include "Caution," "Warning," and "Danger," help to communicate safety precautions and proper handling instructions.

For instance, a product labeled with "Danger" typically indicates a high level of toxicity, while "Caution" suggests a lower level of toxicity. This system is part of the efforts to promote safe pesticide use and to ensure that handlers are aware of the potential risks involved in using the product.

The other options do not relate to the signal word. The color of the pesticide does not indicate its toxicity level; the price is unrelated to health safety concerns; and the brand name reflects marketing rather than the safety or toxicity of the product. Thus, understanding the signal word is crucial for safe and responsible pesticide application.
