Abstract

Electrostatic spraying consists of charging droplets with electric charge, creating an electric field can increase the attraction of droplets by the plants. The objective of this study was to develop an electrostatic device for a hydraulic backpack sprayer, using a high voltage and low cost source. An automotive ignition coil was connected to an electronic circuit powered by a 12 volt battery. The high voltage supply was installed on the rear of the sprayer and connected to a indirect electrification device, which was constructed of copper, measuring 0.10 m in diameter and 0.03 m thick. Flow measurement in the spray nozzle was performed using a Faraday cage, connected to a micro-ammeter. The source provided nine different working conditions, with adjustable voltage between 4.2 and 12.8 kV, which allowed for obtaining charge/mass ratios of 0.3 mC kg-1 to 4.1 mC kg-1, working with a flow rate of 0.6, 1.5 and 1.9 L min-1.
