Abstract

Hydraulic spray equipments are commonly used for pesticide application due to their flexibility under different situations. The spray nozzle is the key component to ensure distribution uniformity and suitable spectrum of droplets. The distribution uniformity is characterized by the coefficient of variation (CV) of the surface volumetric distribution, which are inversely proportional. This study was done to evaluate four different nozzles (XR 110 02 VK, AXI ISO 110.03, AXI ISO 110.04 e AXI ISO 110.05), with spray boom height at 0.4, 0.5 or 0.6 m from the target, at the operating pressure of 200, 300, or 400 kPa. The data showed that spray boom height and pressure influenced the distribution uniformity of the liquid. The most appropriate height-pressure combination for the XR11002VK was 0.4 m-400 kPa, with CV of 8.5%, for AXIISO110.03 and AXIISO110.04 was 0.4 m -300 kPa, with CV of 7.1% and 6.3%, respectively, while for AXI ISO 110 05 JACTO the best was 0.5 m-200 kPa with CV of 7.7%.
