Abstract

Abstract

Background: Pesticide spray drift, which is the movement of pesticide by wind to any location other than the intended area, is

hazardous to human, animal, food safety and environmental health. It is not possible to completely eliminate spray drift during

spraying with field crop sprayers, but spray drift can be reduced by developing new technologies. The most common methods to

reduce spray drift are carrying the droplets to the targetwith air-assisted spraying, electrostatic spraying, preferring air induction

nozzles and boomshields. With thesemethods, it is not possible tomake a change on the sprayer depending on thewind intensity

during spraying. In this study, a novel servo-controlled spraying systemwas designed and developed to change the nozzle orientation

angle in the reverse direction of the wind current to reduce the ground spray drift in real time and automatically in a wind

tunnel. The displacement in the spray pattern (Dc) was used as a ground drift indicator for each nozzle to evaluate the spray drift.

Results: The developed system, operated by LabVIEW software, calculated different nozzle orientation angles depending on

nozzle types, wind velocities and spraying pressures. Orientation angles calculated for different test conditions achieved in

reduction were up to 49.01% for XR11002 nozzle, 32.82% for AIXR11002 nozzle and 32.31% for TTJ6011002 nozzle at 400 kPa

spray pressure and 2.5 m s−1 wind velocity.

Conclusion: The developed system, which has a self-decisionmechanism, calculated the nozzle orientation angle instantaneously

according to the wind velocity. It has been observed that the adjustable spraying nozzle system, sprayed with high precision

towards the wind in the wind tunnel, and the developed system have advantages compared to conventional spraying systems.
