Which of the following best describes a pesticide's label?

A pesticide's label is a crucial component that serves multiple purposes but primarily focuses on safety and effectiveness. It provides detailed instructions regarding how to properly mix, apply, and store the pesticide, as well as guidelines on safety precautions that need to be taken during its use. This ensures that users can handle the pesticide without endangering themselves, others, or the environment.

In addition to usage instructions, the label often includes information on the correct dosage, any specific environmental considerations (like protecting beneficial insects or avoiding water source contamination), and details about any potential side effects or risks associated with improper usage. This comprehensive guidance makes it an essential tool for anyone applying pesticides, emphasizing its role in promoting responsible and informed application practices.

While the other options may present some relevant information, they do not capture the primary intent and significance of a pesticide label. Pricing is not included as it varies and is not pertinent to safe usage guidelines. Contact information for regulatory agencies is generally not a primary focus and can differ based on local regulations. Shelf life might be mentioned, but it is not the core purpose of the label. Thus, the correct choice highlights the label's essential function in ensuring safe and effective pesticide use.
