During a sprayer calibration test, which data should be recorded?

• A. Volume, time, and area covered.
• B. Temperature and wind speed only.
• C. Pesticide color and odor.
• D. Battery level and fuel consumption.

Answer: (A)

Calibrating a sprayer hinges on knowing how much liquid is delivered over a known area in a set amount of time. Recording the volume collected, the time of spraying, and the area covered provides the essential data to calculate both the flow rate (volume per time) and the application rate (volume per area). This information lets you adjust nozzle performance, pressure, or travel speed to reach the target rate accurately. Temperature and wind speed matter for drift and performance, but they don’t tell you how much product is being applied. Pesticide color or odor doesn’t indicate application amount, and battery level or fuel use relates to equipment operation rather than calibration data.
