What is the purpose of including the EPA establishment number on pesticide labels?

The inclusion of the EPA establishment number on pesticide labels serves as a vital identifier for regulatory purposes. It specifically indicates the establishment or facility where the pesticide product was manufactured. This number helps to ensure traceability and accountability in the production process and can be crucial in case of safety issues, recalls, or investigations regarding the product. By knowing where a pesticide was produced, regulatory agencies like the EPA can ascertain compliance with safety and environmental regulations and monitor manufacturers for adherence to standards.

Other options do not accurately reflect the purpose of the EPA establishment number. For example, while effectiveness might be an important factor in pesticide products, the establishment number does not indicate how effective a product is. Similarly, consumer pricing does not correlate with the establishment number, nor do production notes pertain to the specific identification function that the number provides. Thus, the focus is strictly on the identification of the manufacturing site for the product, highlighting safety and regulatory compliance.
