Control of orchard spraying based on electronic sensing of target characteristics


, : Control of orchard spraying based on electronic sensing of target characteristics. Transactions of the ASAE, American Society of Agricultural Engineers 30(6): 1624-1630, 1636

A conventional air-carrier orchard sprayer was retrofitted with a microcomputer-based sprayer control system. A foliage vol. measurement system based on ultrasonic range transducers was interfaced to a 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 vol. savings of 28-35% and 36-52% in peaches and apples, resp.
