Fig 2: This image shows the results of a sprayer calibration in a high-density orchard. Water-sensitive paper was placed in the target tree in four position and sprayed with the grower's typical method of 660 L/ha using 18 nozzles. By making small adjustments to the spray distribution over the boom and adjusting driving speed and air handling, the spray operator achieved minimally acceptable coverage using the CAS-prescribed 400 L/ha over 14 nozzles.
