Pesticides spray nozzle is an essential component to the sprayers of almost all kinds. Orifice tip of nozzle emits the spray solution into finer droplets of desired size and spectrum and sprayed on agricultural field crops. Hollow-cone type nozzles fitted with circular cone orifices are very effective to spray finer droplets due to swirling action of swirl plate. However, these nozzles fail to maintain their droplets size and spray pattern due to wear which results an increase in average orifice diameter (AOD) of nozzle. Three types of hollow-cone nozzles with circular orifices made of plastic, stainless steel and ceramic were studied to investigate the effect on the AOD of orifices under microscopic image analysis due to wear. The experiment was conducted at three different spray pressures of 3.5, 7.0 and 10.5 kg cm-2, respectively. Statistical analysis revealed that the orifice plates made of ceramic materials were the most effective as compared to stainless steel and plastic orifices studied.
