Abstract
In vine cultivation, pests are obstacles to obtaining crops that correspond both qualitatively and quantitatively. In this work, main working qualitative indices were determined. These working qualitative indices were determined under real field conditions using 2 types of nozzles, an air injection nozzle and a standard nozzle. The working qualitative indices determined were DV1, DV5, DV9, coverage degree, number of drops and the amount of solution deposited on target surface. For both speeds of 5 and 7 km/h, DV5 values classified the spray extra and ultra coarse spectrum. The coverage rate was between 55% and 99% regardless of travel speed.
