If a term on a pesticide label is not defined, what should you do?

• A. Ignore it and proceed
• B. Ask a coworker for guidance
• C. Check the Safety Data Sheet for a definition
• D. Contact the PMRA Call Line for clarification

Answer: (D)

When a term on a pesticide label isn’t defined, you must obtain an official interpretation from the regulator to ensure proper and legal use. The label is the binding instruction for applying the product, and authoritative definitions come from the agency that approves and oversees pesticides. In Canada, that agency is the Pest Management Regulatory Agency (PMRA). They provide clarified definitions and guidance for label terminology so you can apply the product safely and in compliance. The Safety Data Sheet can offer hazard and handling information, but it isn’t a source of official label term definitions. Relying on a coworker’s guidance may be helpful for routine practices, yet it isn’t authoritative. Proceeding without a clear definition or official guidance risks misuse, safety hazards, or regulatory noncompliance.
