METHOD FOR CHEMICAL TREATMENT OF PLANTS AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2007 - IPC A01M7/00 

FIELD: chemical treatment process, in particular, process used in vegetable growing.

SUBSTANCE: method involves simultaneously treating plants with preparations in coverings isolated from one another, above plant rows and in row-spacings; creating turbulent-vortex motion in order to embrace the entire surface of stems and leaves at their both sides during spraying of preparations onto zones under coverings, above plant rows. Apparatus has unit with preparation containing reservoirs fixed to unit, compressors, pipelines for feeding of liquid preparations into internal cavity of tunnel coverings, above plant rows and covering above row-spacings. Tunnel coverings are formed within single block of all-metal carcass and are positioned so as to change distance therebetween. Tunnel coverings are connected with one another at their end sides by means of movable partitions and from the top by means of detachable closure so as to define coverings isolated from plant rows above row-spacings. Nozzles for spraying of plant rows with preparations are arranged centrally of and within internal cavity of tunnel coverings, in their upper parts and are equipped at their lower parts with rotating blade-type sprayers loosely fixed for rotation on pins and driven into rotation by flows of liquid preparations oriented on said sprayers.

EFFECT: decreased consumption of preparations and reduced extent of environment contamination thereby.
