What records must be kept for each herbicide application and for how long are they typically retained?

• A. Date, product name, EPA registration number, rate per acre, area treated, crop/target, application method, weather conditions, REI/PHI, applicator; retain for at least 2 years as per Ohio rules.
• B. Only date and product name; keep for 6 months.
• C. Weather conditions only; indefinite retention.
• D. EPA registration number only; 1 year.

Answer: (B)

Documenting herbicide applications involves recording what was applied, when, where, and under what conditions, plus who applied it, so you can show compliance with the label and respond if questions arise later. In Ohio, you typically keep a complete record for each application and retain those records for two years. A proper record includes the date, product name, EPA registration number, rate per acre, area treated, crop or target, application method, weather conditions at application, any REI or PHI considerations, and the applicator’s name. This level of detail ensures you’re following label directions, protecting worker safety, and having a reliable reference for audits or incident reviews. The choice describing only date and product name with a six-month retention would not meet standard Ohio requirements, which call for a fuller record set and a two-year retention.
