Study on Utility Improvement of Air-Assisted Electrostatic Sprayer

Abstract

By combining electrostatic spraying and air-assisted technology, we developed an unmanned pesticide-spraying machine that achieved pest control performance at par with hand spraying. In the test environment, in which an actual machine was used for tomatoes and cucumbers, the effect of pest control was better than that obtained through hand spraying even after reducing spray volume by 20%. In field verification tests for high-wire cultivation of tomatoes, the adhesion performance of the developed machine was better than that of a common machine even after reducing spray volume by half to stabilize the actual machine run. However, in case of soil cultivation, where the road surface was uneven, the adhesion performance was worse than that of common hand spraying because a stable run could not be achieved for the actual machine.
