ABSTRACT:
Apparatus for spraying plants with liquid treatment chemical such as an insecticide, fungicide, herbicide or the like, includes a reusable container having inlet and outlet hose connections, and a disposable cartridge which is inserted into the container. The cartridge comprises a pressure-sensitive container in the form of a piston cylinder or a collapsible bag containing the liquid chemical, and is mounted within a rigid casing or jar communicating with a stream of water under pressure entering the inlet hose connection. The stream of water also flows through an axial bore in the head of the reusable container to the outlet hose connection, passing from a high pressure side through a mixing chamber to a low pressure side. The pressure sensitive container has a precisely-dimensioned outlet aperture communicating with the mixing chamber so that liquid concentrate is forced under pressure from the pressure-sensitive container of the cartridge and mixes with the flow of water in a precise pre-selected micro-dispensing ratio, regardless of the pressure of the water supplied to the apparatus.
