What information should you include in an application log or record for compliance?

• A. Date
• B. Product name and EPA number
• C. Rate and location
• D. Date, product name and EPA number, rate, location, purpose, applicator, and weather/site conditions

Answer: (D)

Keeping a complete application log is essential for proving compliance with pesticide labels and regulatory requirements. The most thorough record includes the date, product name and EPA number, rate, location, purpose, applicator, and weather/site conditions. Each detail serves a purpose: the date shows when the application happened; the product name and EPA number identify exactly which product was used and allows verification of label-specific requirements; the rate confirms the application stayed within label-approved amounts; the location pinpoints where the product was applied for accountability and drift or sensitive-area considerations; the purpose clarifies what pest or site was targeted and supports timing and usage rules; the applicator records who performed the work for accountability; and weather/site conditions capture factors that influence drift risk, efficacy, and any label weather restrictions. Together, these elements create a complete, auditable record. Recording only date, or only product name and EPA number, or only rate and location would leave important information out and hinder regulatory review and traceability.
