• A. One year.
• B. Two years.
• C. Three years.
• D. Five years.

Answer: (D)

Keeping pesticide application records for a sufficient period is essential for traceability and accountability. In Alberta, you’re required to retain those records for five years. This window gives you a reliable history to review past treatments, support inspections or audits, and address any recalls or incidents that might arise long after an application.

Make sure the records cover the key details of each application: the product name and active ingredient, registration or license information, the date, the location or field, the area treated, the rate or amount applied, the method or equipment used, and any weather or conditions relevant to drift and safety. If a label or permit ever specifies a longer retention period, follow that instruction, but five years is the standard here. Shorter retention periods make it harder to demonstrate compliance or respond to future inquiries.
