Abstract (en)

[origin: WO9963809A1] Method and apparatus for agricultural or horticultural spraying is based upon the cartridge system disclosed in GB 2304060A in which the concentrate medium is dispensed by a plunger into a flow of extender medium or dilutant at a rate controlled by a constant speed drive to the piston. This system is modified by eliminating the need for a supply of cartridges of differing cross-sectional sizes (to provide differing rates of application of medium to the crop) by using the cartridge/plunger assembly as a volumetric control means for at least one step in a preliminary or primary dilution or extension step in which the concentrate as supplied by the manufacturer is partially diluted or extended so that when the main dilution or extension step occurs, the required final concentration will be achieved.
