Potato is an important crop cultivated everywhere in the world. One of the reserves for increasing potato productivity is a technological technique performed during the period of plant care − decapitation. It consists in the removal of the apical kidney, as a result of what the lateral buds are activated, which germinate and form an additional leaf surface, which contributes to an increase in the crop yield. However, a violation of the plant tissue at the cutting site is the site of penetration of pathogenic microorganisms, especially viral ones, which leads to deterioration of varietal qualities. To reduce the negative impact of these microorganisms on the plant, the cut should be sterile. This can be achieved, if the knife is treated with a disinfectant solution before contact with the shoot. The paper considers the possibility of using sprayers for this purpose, which are used on sprayers for chemical plant protection. Based on the obtained calculated and experimental data, recommendations on the choice of sprayer parameters and the mode of the disinfecting system are substantiated. As a result, it was determined that, in order to achieve the goals, it is possible to use TX-VS2 spray tips with a system pressure of 0.40 MPa and a tilt angle to the vertical of 22.5 to 26.7 degrees. “
