If your sprayer's output does not match the label after calibration, which is the recommended first adjustment?

• A. Change nozzles
• B. Change speed and/or pressure
• C. Recalibrate with a different fluid
• D. Ignore and proceed

Answer: (B)

Application rate is controlled primarily by travel speed and spray pressure for a given nozzle. When your sprayer’s output doesn’t match the label after calibration, the first adjustment to bring the rate back to target is to tweak how fast you move and the operating pressure. Slowing down (or speeding up) changes how much chemical is applied per area, and adjusting pressure within the labeled range changes the volume that exits the nozzle at a given speed. These adjustments are the quickest, most direct way to align the delivered rate with the label without altering hardware. Changing nozzles introduces different flow and droplet characteristics and should come after confirming the current setup can meet the rate with speed and pressure. Recalibrating with a different fluid can affect viscosity and flow and should follow after validating the setup with the original fluid. Ignoring the discrepancy isn’t appropriate because adhering to the labeled rate is essential for efficacy and safety.
