How long should records be kept for pesticide practice?

• A. 12 months
• B. 24 months
• C. 36 months
• D. 60 months

Answer: (B)

Recordkeeping duration is about keeping a traceable history of pesticide use. For Utah aquatic pesticide practice, records must be kept for twenty-four months. This two-year window supports regulatory audits, lets you verify what was applied, where, and when, and provides a reference for any follow-up actions. When you record an application, include the date, product name and EPA registration number, active ingredient, formulation, rate and total amount applied, treatment site, target pest or organism, application method, and weather conditions at the time (wind, temperature, humidity) along with any observations about drift or environmental impact. The 24-month requirement is the standard in this context; shorter periods would miss expected review time, while longer periods add burden without adding necessary value for routine practice.
