Currently, the available crop and garden sprayers do not have the ability to spray palm trees at high altitudes. In this study, an air blast sprayer was optimized for high palm trees and its performance was evaluated and compared with the performance of trailed and wheelbarrow lance sprayers. In order to evaluate the sprayers in the region, eight important traits were considered. The results of this study showed that the optimum air blast sprayer quality was better than that of the trailed and wheelbarrow lance sprayers, such a way that the spray quality coefficient was 1.81 versus 3.3 and 3.84 for trailed and wheelbarrow lance sprayers. The presence of poison on the ground, in turbine sprayer was seventy-five percent less compared to the trailed and wheelbarrow lance sprayers. The amount of solvent in turbine sprayer is about 50% lower than that of tow lance sprayers. Spraying capacity was 54 trees per hour without the need for the worker for turbine sprayer and for trailed and wheelbarrow sprayers were 30 and 27 trees per hour with 1 worker. According to the results of this study, it is better to use an optimized turbine sprayer for spraying palm trees with different heights.
