Abstract:

In this study, we compared the aerial electrostatic spray with non-electrostatic spray by helicopter R44 and fixed-wing aircraft Y5B equipped with an own-made aerial electrostatic spraying system. The results showed that the spray deposits on targets and leaves of tree crowns were notable enhanced comparing with the non-electrostatic and conventional aerial spray. The spray deposits were fine, uniform and the densities were 1.0~1.75 times higher than the non-electrostatic spray. Deposit rate of the electrostatic spray on the backs of leaves by helicopter R44 was 2.15 times of the non-electrostatic, and 3.31 times of the conventional aerial spray. The deposit rate of the electrostatic spray on the backs of leaves by the Y5B was 2.38 times of the non-electrostatic, and 3.44 times of the conventional aerial spray.

Key words: aerial electrostatic spray, non-electrostatic spray, spray deposit
