The goal for all pesticide applications should be to get every drop to the crop. Calibration ensures that the appropriate product rate is applied by the sprayer, while optimization ensures that the product is delivered onto the intended target. Calibrating and optimizing the sprayer are essential to sustainability, as they affect the environment, farm workers, and economic impact through fruit quality and pesticide costs. In six steps, this publication explains how to measure ground speed and nozzle output, check and adjust airflow and nozzle alignment, and verify coverage for an airblast sprayer. Methods are outlined for manual completion of the steps, and simplified formulas and suggestions for tools that can make the process faster are included.
