Which component is NOT included in the primary display on a pesticide label?

The primary display on a pesticide label is designed to provide essential information that users need for safe and effective use of the product. This includes precautionary statements, directions for use, and the registration number, all of which are critical for ensuring that the pesticide is applied correctly and safely.

Precautionary statements inform users about potential hazards and necessary safety precautions, while directions for use detail how to apply the pesticide effectively and safely. The registration number identifies the product and ensures it has been approved for use by regulatory authorities, reflecting compliance with safety and efficacy standards.

The site of action grouping and identification symbol, while important for understanding how the pesticide works and its potential resistance management, is not part of the primary display. This information is usually found in more detailed sections of the label that may not be immediately visible or required for the initial, essential application of the product. Thus, it is not included as a primary component on the label itself.
