A spray pattern analysis system was developed to assess quantitatively the incremental liquid application rates from ground application equipment. The spray pattern was evaluated by using patternator constructed confirming to specification of ISO 10064. The patternator was made by 30 number of channels each 7.5 cm width at the top and 2 cm depth. The motorized knapsack mist blower was placed at one side of the corrugated sheet in such a way that the corrugations were perpendicular to the nozzle position. Beakers were kept below the corrugations for collecting the spray materials. The speed of the blower was measured with tachometer. The sprayer unit was placed at a distance of 1 m from the patternator. The engine speed was regulated by accelerator. The spray distribution pattern for motorized knapsack mist blower recorded maximum amount of 0.07 l min-1 spray liquid deposited at 5500 rpm engine speed at 6.0 mm orifice diameter.
