Why is calibration essential for pesticide application?

• A. It reduces the risk of drift.
• B. It ensures the equipment delivers the labeled rate uniformly across the target area.
• C. It increases application speed.
• D. It makes PPE unnecessary.

Answer: (B)

Calibration ensures the spray system delivers the exact amount the label specifies across the treated area. The labeled rate represents the active ingredient per unit area, so when you calibrate, you make sure every part of the field gets that same amount. If the sprayer isn’t calibrated, some spots can receive too little (ineffective control) and others too much (crop injury, waste, and environmental risk). By measuring actual output and adjusting nozzle flow, pressure, and travel speed, you achieve a uniform application that matches the label everywhere you treat. While drift, speed, and PPE needs are influenced by other factors, calibration is what keeps the applied rate correct and consistent.
