Which component is NOT included in the definition of pesticide labeling?

In the context of pesticide regulation, labeling is a crucial aspect and includes specific components that provide essential information about the pesticide's safe and effective use. The correct choice, which is marketing brochures, is identified as something that does not fall under the official definition of pesticide labeling.

Pesticide labeling typically comprises the following key elements:

• The label itself, which contains instructions, precautions, and required legal language pertaining to the product's application and safety.

• Safety Data Sheets (SDS), which provide detailed information about the chemical properties of the pesticide, including hazards and recommended safety measures.

• Section 24(c) labeling, which refers to special local needs permits that allow specific uses of a pesticide not included in the federal registration, providing additional labeling requirements for those unique situations.

Marketing brochures, on the other hand, are promotional materials that may provide general information and advantages of the product but do not hold legal weight or specific safety and usage instructions outlined in the official labeling. As such, they do not constitute part of the official pesticide labeling required by regulatory authorities.
