Which factor is explicitly included in the main elements of a sprayer calibration record?

• A. Date; operator; equipment; nozzle type; travel speed; pressure; GPM; swath width; calculated rate per acre; final rate
• B. Weather conditions only
• C. The color of the spray tank
• D. The brand of gloves worn

Answer: (A)

Calibration records document the parameters used to set and verify the pesticide application rate. The main elements you’ll see are date, operator, equipment, nozzle type, travel speed, pressure, GPM, swath width, calculated rate per acre, and final rate. These pieces are the core data that drive the calculation of how much product is actually applied per acre and provide a traceable record of how the sprayer was set up and operated. The other items listed aren’t part of the essential calibration record: weather conditions, while important for performance, aren’t a required core element of the calibration math; the color of the spray tank and the brand of gloves worn do not affect the rate calculation or documentation.
