Abstract : In orchard, it is difficult to spray the pesticide uniformly throughout the tree by conventional methods. Air carrier sprayer is a viable alternative to hydraulic sprayer especially when sprayer has to deposit chemical on target, which are far from sprayer. An air carrier sprayer was evaluated for pesticide application in Mango orchard. The flow rate of spray nozzle was measured by operating sprayer at a speed of 7, 8.5 and 10 km/hr with four different dosage discs. The flow rate of air carrier sprayer varies from 0.6 lit/m in to 2.42 lit/m in. with different dosage discs. The spray swath and horizontal throw of air carrier sprayer increases with increase of speed. The air velocity increase in distance from blower outlet from 3 m to 15 m. The VMD, NMD and UC values vary from 279.87 µm, 2.456 to 258.44 µm, 93.55 µm, 3.52 for 0.92 to 2 lit/m in. discharge rate, respectively. The air carrier sprayer deposit spray uniformly on inner and outer side of tree at different locations and hence recommended for orchard spraying.
