On a pesticide application record, which identifier is used for the product?

• A. EPA registration number
• B. Lot number
• C. Manufacturer’s address
• D. Customer’s tax ID

Answer: (A)

The product’s EPA registration number is the identifier because it is the official, unique tag assigned by EPA to every registered pesticide product or formulation. This number ties directly to the exact label, active ingredients, usage directions, and legal restrictions, making it the reliable way to document which product was applied. A lot number tracks a specific production batch and isn’t used as the standard product identifier on field records. The manufacturer’s address is just contact information, not a way to identify the product, and the customer’s tax ID has no relevance to pesticide product identification.
