The conducted research was done by using a radial sprayer Hardi Zaturn in vineyard. The aim of this study was to gain knowledge about the impact of the main technical factors of spraying (nozzle type, sprayer's working speed and the spraying standard) on the coverage of the treated area, the number of drops/cm2, the average diameter of the droplets and fluid drift. The sprayer's working speeds used in this research were 6 km/h and 8 km/h and spraying standards were 250, 300 and 350 l/ha. Nozzles which were used in this research are blue (TR 8003), yellow (TR 8002) and green (TR 80015) Lechler nozzles. The study was set up as a three-factorial field experiment with 18 treatments in 2 repetitions depending on the sprayer's settings. For each treatment the tree was covered with 60 water sensitive papers which were later processed using a digital image analysis program ImageJ. In addition to the main factors of the research, the leaf area index and the index of leaf density were measured too. Prior to research, the sprayer has been tested according to European standard EN 13790. By increasing the sprayer's working speed and increasing the spraying standard while reducing the nozzles' ISO number, the coverage of the treated area was increased along with the number of drops/cm2 and drift, while the average diameter of the droplets was decreased. Aial sprayer Hardi Zaturn scored solid results in vineyard; coverage of the treated area ranges from 26,59% (blues nozzle, working speed of 6 km/h and spraying standard of 250 l/ha) to 51,45% (green nozzle, working speed of 8 km/h and spraying standard of 350 l/ha). The best ratio of coverage of the treated area and drift of the liquid in an apple orchard is achieved by having the coverage of the treated area of 64,22% and the drift of the fluid at 17,11% (green nozzle, working speed of 6 km/h and spraying standard of 350 l/ha with working pressure of 10,99 bar).
