Abstract: Controlled drop application is a promising technology for plant protection. It can be realized only with rotary atomizer. Rotary atomization has the advantage that by altering the rotational speed and/or the feed rate, one can produce a predictable drop size, with a comparatively narrow drop spectrum. In the ISSAPP "N. Pushkarov" a hydraulic rotary atomizer was developed and investi-gated in two ways of mounting the spraying body, down and up. Spray volume distribution pattern across of the boom is determined in the various regime of the operation of sprayer. Software for simulation the interaction of adjacent atomizers at a different distance between them has been developed. In accordance with European quality standards, the possible deviation of the sprays on the working width of the machine is determined. The benefits of a rotary atomizer with an upward spraying body have been proven.
