What does the EPA registration number indicate about a pesticide?

The EPA registration number is a unique identifier assigned to a pesticide product that indicates the manufacturer or company associated with it. This number is crucial because it helps regulatory bodies, consumers, and pest control professionals trace the product back to its producer. It ensures that the product has undergone the necessary evaluations for safety and efficacy and is compliant with federal regulations. The registration number provides a way to identify the specific formulation of the pesticide, which can be important for understanding its application, safety protocols, and any potential restrictions associated with its use.

In contrast, the other options do not accurately represent what the EPA registration number signifies. The facility where the product was manufactured, the distribution identification number, or the listing of toxicity levels via signal words are not directly indicated by the EPA registration number itself. The number primarily serves as a link to the manufacturer and facilitates accountability in the industry.
