The ________ must be put in your pesticide application records because it specifically identifies the product that you applied.

• A. EPA registration number
• B. EPA establishment number
• C. Product patent number
• D. Manufacturer's phone number

Answer: (A)

Recording the EPA registration number is essential because it uniquely identifies the exact pesticide product you used. This number links the product to its approved label, including the active ingredients, allowed uses, and safety instructions, so anyone reviewing your records can confirm precisely which product was applied. It stays with the product regardless of lot or batch, providing reliable traceability for compliance and any potential recalls or investigations. The establishment number identifies where the product was manufactured or registered, not the specific product itself, so it doesn’t tell you which product you applied. A patent number isn’t used in routine application records, and a manufacturer’s phone number isn’t an identifier for the product.
