EN In order to obtain abundant crops of satisfactory quality, it is necessary to apply liquid chemicals during agrotechnical procedures. It is important to target the treatment for a specific purpose and reduce the losses of applied chemicals. The aim of a precise protection technique is to provide the active substance in the proper place, in sufficient quantity and in the appropriate form. One of the approaches to modify the physicochemical properties of plant protection products is the addition of small amounts of polymers. The efficiency and safety of spraying process is determined by properly selected atomizers. In the agriculture section on spatial cultivation and vegetables, vortex atomizers are usually used in the spraying process. Two new constructions of two-phase atomizers with a swirl flow and the experimental results on the spraying of aqueous solutions of sodium carboxymethylcellulose with various concentrations were shown in this chapter. The obtained results were compared with the data obtained when spraying water. The addition of polymer allows to obtain a much larger number of droplets with large diameters and reduces the share of the smallest sized droplets. As the concentration of polymer increased, larger diameter droplets were obtained and the spray angle was reduced. The obtained results confirm the application possibility of the developed constructions in the agriculture area.
