Performance Evaluation of a Boomless Oscillating Field Sprayer at Different Spraying Pressures and Oscillating Rates

The efficiency expected from any pesticide depends largely on the type of plant protection machine used in spraying and operating parameters selected machine. Today, sprayers with different wing width are widely field spraying. Especially large working widths, it is difficult to work at high speeds due weight. In this study, wingless sprayer effectiveness was evaluated. Occasionally for instead standard booms, commercial name Electropar, which operated pressure oscillating nozzles used. Since has no wings, can spray tractor speeds. optimum sprayer, pestisit distribution uniformity a horizontal surface, etc. Its unknown. provided by pressures nozzle oscillation rates, volumetric fluid throughout were determined. three (1, 2 3 MPa) transverse jet units moving opposite directions relative each other ground two oscillations (44 60 rpm) determined portable patternator. Operation high-pressure cone unit 1 MPa rpm more uniform than parameters. increase caused an volume accumulated patternator's grooves same height sampling distance. width, depending conditions specified boomless varied between 11.20 12.80 m speed pressure.
