Regular calibration helps ensure spray coverage remains accurate under varying conditions. Which outcome does it support?

• A. Poor coverage
• B. More drift
• C. Correct application rate
• D. Longer downtime

Answer: (C)

Regular calibration keeps the sprayer delivering the target amount of product per area, even when conditions change. The goal is to achieve the prescribed application rate, which determines how well pests are controlled and how safely and efficiently the product is used. Over time, factors like nozzle wear, pressure fluctuations, spray distance, and application speed can alter actual output. Calibration measures the real spray volume per area and adjustments are made so the rate stays on target. This directly supports accurate coverage across varying conditions. Poor coverage or excessive drift are outcomes that calibration helps prevent, while longer downtime isn’t tied to the calibration of spray output.
