Using manufacturer guidelines as a substitute for calibrating equipment is:

• A. True
• B. False
• C. Only for new equipment
• D. Only when the label rates match

Answer: (B)

Calibrating spray equipment is essential to hit the labeled rate in real conditions. Manufacturer guidelines give a starting point for setup, but they don’t reflect how your specific gear performs in the field—things like nozzle wear, pressure fluctuations, spray volume, speed, and environmental factors can all change the actual output. If you rely on guidelines alone, you risk over- or under-application, drift, and potential regulatory issues. So using manufacturer guidelines as a substitute for calibration isn’t appropriate; calibrate to confirm the true output your equipment delivers and adjust to match the label rate. It isn’t something you only do for new equipment or only when label rates happen to match—calibration should be routine whenever you apply pesticides.
