The development of new technologies of phytosanitary applications aims to reduce environmental contamination, drift, liquid volume and increase the safety of the applier, as well as the improvement of the liquid deposition, in order to improve the spraying quality. The objective of this work was to determine the uniformity of air distribution along the airassisted spraying bar, and evaluate the uniformity of the liquid, carried out with four speeds of fan rotation and three heights of the spray bar in relation to the test bench. The fan axis rotation of 2.100 rpm presented the best results. The air distribution profiles were irregular, and the wind distribution at 0.5 m from the bar presented a variation coefficient lower than that obtained when the bar was 0.3 m far from the reading point.Downloads
