An efficient pesticides application is only possible with nozzles that provide satisfactory volumetric distribution and uniform droplet spectrum, once the spray nozzle is the main component of the hydraulic spraying. Therefore, the aim of this work was to characterize the hydraulic spray nozzles LD 11002 and MAG-2. The experiment to determine the pattern and uniformity of distribution was arranged in a factorial scheme 2 x 3 x 4, composed of two models of nozzles, three boom heights and four working pressures, analyzed in completely randomized design, with three replications for uniformity of distribution and fifteen replications for pattern of distribution. Symmetry of distribution for the nozzle LD 11002 was verified by the data from pattern of distribution. The determination of droplet spectrum was performed by the laser particle analyzer model Spraytech, and the experiment was arranged in a completely randomized design with four treatments (four working pressures) and a total of twenty-five replications. The nozzles LD 11002 and MAG-2 did not have uniform distribution at the height of 0.5 m. The nozzle LD 11002 showed asymmetry and it was influenced by working pressure. The droplets diameter produced by the nozzles LD 11002 and MAG-2 reduced with increasing the working pressure.Downloads
