Control of orchard spraying based on electronic sensing of spray target characteristics


, : Control of orchard spraying based on electronic sensing of spray target characteristics. Paper, American Society of Agricultural Engineers (87-1069): 23

A conventional air-blast orchard sprayer was retrofitted with a microcomputer-based sprayer control system. A foliage volume measurement system was based on ultrasonic range transducers interfaced to the computer. Three 3-nozzle manifolds on each side of the sprayer were controlled by the computer using control algorithms based on spray deposition studies. Use of the full control system resulted in spray volume savings ranging from 28 to 35% and 36 to 52% in peaches and apples, resp.
