What is the purpose of calibrating application equipment?

• A. To maximize the pesticide amount used per acre.
• B. To check the manufacturer's manual for warranty.
• C. To ensure the correct application rate and reduce drift.
• D. To shorten the preparation time.

Answer: (C)

Calibrating application equipment ensures you apply the right amount of pesticide per acre and control where it goes. By measuring the actual spray output over a known area, you can adjust nozzle choice, pressure, and travel speed to hit the label rate accurately. This accuracy helps the product perform as intended while protecting non-target areas and water sources by reducing drift. It isn’t about using more product, checking a warranty, or rushing preparation—the goal is precise, label-compliant application that minimizes environmental risk.
