A new large scale precision track sprayer has been developed and evaluated for spray deposition and pesticide application research under controlled conditions. The spray room is fitted with a 4 m wide electrically driven boom, suspended 4 m above ground, running on a 12 m long I-beam. It is fitted with 9 independently controlled shut off valves and nozzles. Sprays can be applied to live plant canopies up to 3 m tall within a 2 m × 3 m sample area. The number, location and type of nozzle on the boom can be altered, as can spray liquid pressure and boom speed, in order to simulate a wide range of spray application scenarios. Calibration of the large-scale precision track sprayer has been undertaken for a range of droplet spectra, from extremely coarse to very fine. This paper documents the calibration results and discusses the potential use of this facility for pesticide application research.
