Much attention is currently paid to the study of losses of pesticide working solutions due to wind drift and substantiation of directions for their reduction. Leading manufacturers of agricultural machinery for crop protection agent application have developed recommendations on their adjustment and operation in windy weather. Additional equipment and systems are being developed for boom sprayers to reduce the impact of wind on the spraying torch or to provide transportation of drops of pesticide working solutions to the treated surfaces. These developments, along with undoubted advantages, have a number of disadvantages that reduce the quality of technological operations and increase their energy consumption and cost. The article analyzes wind protection devices, substantiates the requirements to their designs and determines the conditions of use in field sprayers for grain crops processing. Designs of wind deflectors that allow to use wind energy to improve the quality of technological operations are proposed. The laboratory researches on studying the influence of wind protection devices on the change of the coefficient of target utilization of working liquid and the range of its droplets drifting have been carried out. As a result, it was found that the greatest influence on the value of droplet drift has a dispersity of atomization, sprayer installation parameters, wind speed and direction. The use of wind protection devices allows to increase the coefficient of target liquid utilization by 18-39 % at the studied wind speeds from 1 to 7 m/s. This will improve the quality of chemical plant protection and reduce losses of preparations due to drift during treatments in windy weather.
