The article presents the results of experimental studies of the parameters of spraying aqueous solutions of pesticides using agricultural UAS. The article describes the features of the methodology and the required technical means for determining the parameters of settled droplets during spraying using UAS. Directions for the development of methods for instrumental assessment of the parameters of agricultural technological processes using UAS are proposed. The results of determining the parameters of actual treatment zones when applying spot spraying technology using UAS are presented. The features of the formation of a spray cone of the working fluid under the influence of turbulent air flows created by propeller-motor groups of UAS are analyzed. Operational and technological indicators of the technological process implementation using UAS for spot and differentiated spraying technologies are determined, and their comparative analysis is conducted. An analysis of the potential economic efficiency and options for the use of UAS for spraying agricultural lands with aqueous rasters of pesticides is presented.
