Abstract: Pesticide application is accompanied by its losses due to the drift of the droplets of the working liquid caused by the wind outside the treatment area, which reduces the efficiency of chemical protection and increases impact on the ecological state of the environment. Influence of the precipitating (i.e. top-down) air flow has been determined upon the reduction of the drift of sprayed liquid droplets under the impact of a lateral wind, as well as distribution of the sprayed liquid studied by weight and length depending on the pressure of the working fluid in systems of various sprayers. At speed side wind 5.0 m.s-1 and deposition of flow at a speed of 15 m.s-1 the amount of fluid that settled, increased to 30% for spray ST 110-02 and 12% for spray ID 120-02.
