Which items are essential to document in a Minnesota pesticide application record?

• A. Date of application; product name and EPA registration number; rate per acre with field/crop treated; records kept for the required period.
• B. Weather conditions and wind speed.
• C. The color of the container and the lot number.
• D. The price per acre and supplier contact.

Answer: (B)

Keeping a pesticide application record is about documenting exactly what was applied, where, when, and in what amount, so you have a traceable record for compliance and safety. The essential items you must record are the date of application, the product name and its EPA registration number, the application rate per acre along with the field or crop treated, and the period for which the records must be kept. These details ensure you can verify LABEL directions were followed, identify which fields received which products, and demonstrate you maintained records for the required retention time in case of audits or future reference.

Weather conditions or wind speed can be useful context for understanding drift risk, but they are not the core items required to prove the application event itself in Minnesota’s official recordkeeping. The color of the container and lot number aren’t required either, and price per acre or supplier contact relates to purchasing, not documenting the application. Focus on recording the date, product name with EPA number, rate per acre, and field/crop treated, and keep that record for the required period.
