FIELD: agriculture.

SUBSTANCE: invention relates to agricultural engineering. The sprayer is a mobile unit, which comprises a utility tractor, pipes, a bar with sprayers, reservoir for working liquid and a power takeoff pump. A direct current generator is mounted on the tractor and is rotated by the power takeoff shaft of the tractor through a reduction gear. The direct current generator is electrically connected to a water electric activation device, hydraulically connected through a pump to the reservoir with working liquid. The water electric activation device is hydraulically connected to sprayers and flexible bars, mounted on an additional pipe, with nozzles which have openings at a tangent to the inner diametre of the nozzles and directed to the root zone of the plants. The nozzles are made from wear-resistant material and rest on the surface of the soil. In the electrical connection between the direct current generator and the water electric activation device, there is a potential switch.

EFFECT: use of the sprayer increases crop yield and resistance of plants to diseases and pests.
