Effective pest control requires precise and uniform application of pesticide on the target area. Air assistance in spraying system improves the deposition uniformly in the entire tree canopy. Requirement of air volume is influenced by leaf area, leaf density and canopy volume of tree. High power air assisted sprayers are used for blanket spray application in developed countries. In India manual or HTP sprayers are used for spraying horticultural crops which results in uneven spraying, incurring more cost and inefficient pest control. To overcome these limitations a suitable centrifugal blower is developed for aero blast sprayer in HDP mango orchard. To assess air volume requirement for spraying on HDP matured mango orchard, tree parameters canopy volume, mean leaf area, leaf density and total leaf area of tree were estimated. Air volume requirement for HDP mango orchard spraying was calculated. The centrifugal blower with forward curved blade was developed to deliver the air of 2.5 m3/s required for effective spraying in HDP mango orchard. The developed centrifugal blower was tested in the laboratory at 1800, 2000, 2200, and 2400 rpm. The desired air discharge of 2.66 m3/s was found at 2200 rpm whereas theoretical requirement was 2.50 m3/s for efficient spraying operation in HDP mango orchard. The maximum blower efficiency of 93.26 per cent and the sufficient spray throw was found at 2200 rpm blower speed.
