Which of the following is a requirement for pesticide labeling?

The requirement for pesticide labeling to include safety directions and proper usage is crucial for ensuring that users can handle and apply the pesticides safely and effectively. Labels serve as the primary source of information for users, providing critical details about how to use the pesticide, the appropriate application rates, precautions to take to protect themselves and others, and instructions for what to do in case of accidental exposure or spills. This information helps to minimize risks to human health and the environment.

While it's important for labels to also be comprehensible to the intended user, and they may indeed be required to be in the local language depending on regulatory mandates, the inclusion of safety directions and proper usage is universally deemed a fundamental requirement. This ensures compliance with safety regulations and promotes responsible use of pesticides.
