What must pesticide applicator certificate holders do within 90 days of a change?

• A. Notify the local city clerk.
• B. No action required.
• C. Notify the Pesticide Management Program of a change in their name or mailing address.
• D. Submit a tax form.

Answer: (C)

Keeping the Pesticide Management Program informed about changes to your personal details is essential because this program handles your certificate and uses your current name and mailing address to send renewal notices, updates, and enforcement communications. If your name or mailing address changes, you must report that change within 90 days so your records stay accurate and you continue to receive important notifications without delay. The other options don’t fit because they don’t involve the pesticide certification program’s records or required communications, and there’s no obligation to notify a city clerk or to submit a tax form for this purpose.
