Pump is communicated with drive of power facility via hydraulic communication hoses with control panel, which is also communicated via hydraulic communication hoses and shut-off valve with pipelines with sprayers, and cutoff valve lever through cables is communicated with probes. Manometer with separation-damper device is located between control panel and shut-off valve.

EFFECT: reduced losses of pesticides during treatment of intensive gardens and vineyards, which does not allow contamination of environment.
