Why is it important to calibrate a sprayer before a field season?

• A. To adjust the sprayer color for visibility.
• B. To reduce the weight of the sprayer.
• C. To determine shelf life.
• D. To ensure application rate accuracy, even coverage, and compliance with the label.

Answer: (D)

Calibration is about making sure what the sprayer actually delivers matches what the product label requires and what the field needs. Before a field season, you calibrate so you know the application rate per acre and that every part of the field receives the same amount, regardless of speed, nozzle type, or terrain. This is essential for effectiveness—the right rate with even coverage helps control pests or weeds without leaving untreated patches or causing plant injury. Calibrating also keeps you in line with the label’s directions, which governs where, how much, and how often you can apply. Staying within those limits protects the crop, the environment, and yourself, and it helps prevent drift or over-application that could lead to regulatory issues or resistance problems down the line. If you skip calibration, changes in nozzle wear, temperature, solution viscosity, or driving speed can throw off the rate and coverage, making the spray unreliable.
