FIELD: agriculture, in particular, plant protection. SUBSTANCE: pneumatic sprayer has frame, working fluid reservoir with level indicator and filling filter, spraying boom, feeding pipeline with filter and cutoff device, air blower, V-belt drive, air distributor, air pipes, working fluid flow rate regulating valve, and spraying tip. Spraying tip has hollow cylindrical body with air branch pipe positioned in center of body upper part and dispersing device with central axial channel, which is communicated with feeding pipeline via branch pipe. Radial channels are extending from axial channel. Radial channels are connected with dispersing device nozzle-type openings arranged in parallel around axial channel. Number of radial channels is equal to that of nozzle-type openings. EFFECT: increased efficiency, simplified construction and reduced adverse effect upon environment. 3 dwg
