Abstract

Laserbased technologies for droplet analysis have existed for decades but most of these devices are not suitable to be moved once calibrated PhaseDoppler interferometer (PDI) technology has enabled the capture of live infield spray particle data such as the particle size distribution velocity and flux which are essential to accurately measure and model the drift of agricultural equipment The objective of this study was to develop and implement methods to determine if drift could be detected and if so to use the data obtained to crossreference its validity with spray drift models AGDISP and WTDISP The spray apparatus consisted of a 12V trailertype sprayer outfitted with a 50 cm high fournozzle boom with 110SG02 nozzles delivering 238 litres/ha at 34 bar This setup was selected to maximise the output of the sprayer and produce the worstcase drift scenario for the given spray system It was observed that driftable particles of a passing and a static sprayer could be detected within close proximity of 8400 cm2 These results also agreed with the model output generated
