What are label warnings on pesticide products designed for?

Label warnings on pesticide products are designed primarily to provide instructions on how to handle, use, and dispose of the pesticide safely. This ensures that users are aware of any potential hazards associated with the product, including toxicity to humans, pets, and the environment, and outlines necessary precautions to take during application. These warnings help to prevent accidents, misuse, and harmful exposure, making it essential for users to follow the guidelines outlined on the label.

While promoting a brand or offering sales promotions might be common marketing practices, they are not the main purpose of label warnings. Similarly, while detail about the product's environmental impact could be important information, it does not encompass the critical safety considerations that label warnings are intended to address. Hence, option B rightly captures the core objective behind the label warnings on pesticide products.
