Equipment for spraying plants and trees with a plant treating liquid injected into turbulent pulsating air streams, including at least one oblong air outlet structure for issuing turbulent pulsating air streams in diverging directions. The air outlet structure has an oblong air inlet opening for receiving pressurized air and includes a plurality of longitudinally arranged air outlets extending outwardly from the air inlet opening. The air outlets each have a respective axis whose angle of inclination differs with respect to an angle of inclination of an adjacent air outlet. At least one spray nozzle is arranged to inject a plant treating liquid into the turbulent pulsating air streams issued from the air outlet structure.

Equipment for spraying of plants with a plant treating liquid injected

Spraying equipment for plants growing in parallel rows comprises a main horizontal air duct and several secondary ducts extending therefrom in downward direction between the rows of plants. Each duct is provided with air outlets directed towards the plants, which are alternately opened and closed by valves so as to eject the air in pulses. One spray nozzle each is positioned in the center of each air outlet serving to eject into the pulsating air stream a jet of spraying fluid which is thereby carried onto the plants covering these from top to bottom. The equipment is attached to the front or rear of a tractor which carries a supply of spraying fluid and a pump serving to supply the material to each nozzle through piping. A blower is positioned in the main duct supplying air under pressure to the secondary ducts and to the air outlets.
