Which item must be present on the retail invoice when purchasing restricted-use pesticides?

• A. License or certification number
• B. Purchase price
• C. Customer age
• D. Retailer tax ID

Answer: (A)

The main idea here is that purchases of restricted-use pesticides must be tied to a licensed or certified applicator. The retailer is required to verify that the person buying the product holds the appropriate pesticide license or operator certification, and to record that license or certification number on the retail invoice. This creates a verifiable link between the sale and a properly trained individual, which regulatory agencies can review during inspections or audits. The license or certification number on the invoice shows that the buyer is authorized to purchase and use restricted-use pesticides.

Other details like the purchase price, the customer’s age, or the retailer’s tax ID are not the regulatory item that demonstrates eligibility to buy restricted-use pesticides.
