Ways to reduce the negative effects of wind on the quality of field spraying

Annotation Purpose. Improving the quality of field spraying by using an air curtain to counteract the negative impact of wind on the quality of this process. Methods. Theoretical substantiation and experimental verification of its results. Results. The method of wind resistance, structural and functional scheme of the device to the sprayer for its implementation are substantiated and an experimental test is carried out, which confirmed the significant effectiveness of the proposed method. Conclusions. By applying a new method to reduce the negative impact of wind on the quality of field spraying, a device for spraying to create an air curtain was developed and tested, which allowed to almost double (up to 10 m/s) the allowable wind speed for this operation compared to better analogues without deterioration quality indicators of their work.
