Which of the following must be included in pesticide labels when applicable?

The inclusion of specific safety instructions on pesticide labels is crucial for ensuring proper handling and minimizing risks associated with pesticide use. A key safety directive that must be included in pesticide labels is the instruction to "store in a locked secured area." This guideline is essential as it helps to prevent accidental ingestion or exposure to children, pets, or unauthorized individuals who could be harmed by the pesticide's contents. Ensuring that pesticides are stored securely is a fundamental safety practice that aligns with responsible usage and regulatory compliance, emphasizing the importance of preventing access to hazardous substances.

In contrast, while brand logos, instructions regarding keeping products away from pets, and materials lists may provide helpful information, they are not universally mandated components on pesticide labels. Each of those elements may enhance user understanding and safety but do not share the same regulatory requirement as instructions for secure storage. The focus on secure storage highlights the importance of safety and responsible management of pesticide products.
