The main objective of this study involved testing of nozzle type, driving speed and wind speed effects on atomization parameters for broadcast spraying application. Two broadcast nozzle types flat fan extended range XR11003 and flat fan drift guard nozzle DG11003 were tested under wind tunnel conditions. To validate spraying results, the reference nozzle of spraying systems flat fan TeeJet nozzle TP11003 was used for comparison. The results of this study indicate an obvious effect of the technical variables and wind variable on atomization parameters. The nozzle DG11003 produced droplet size spectra of D0.1, D0.5 and D0.9 bigger than the extended range nozzle and reference nozzle. The droplet size spectra became smaller under increasing of the driving speed. Droplet size parameters generally tended to be coarser at the higher wind speeds. This study supports the use of nozzle DG11003 as a means for controlling spray distribution.
