The purpose of this paper was to measure the spray pattern displacements (SPD) of two agricultural nozzles using an experimental spray patternator in the laboratory. A SPD measuring technique was developed and SPD data gathered using Spraying System Co.’s 8004 fan nozzles and TK-SS2.5 flood tip nozzles. The mean SPD values for the 8004 fan nozzle were 30 percentage points lower (P<0.05) than that for TK-SS2.5 flood tip nozzle. As expected, the mean SPD values for the high-wind conditions were significantly higher (P<0.05) than that for the low-wind conditions for both the nozzles. This implies that the 8004 fan nozzle would do a better job of spraying and that the spraying should be carried out under low wind conditions.
