ABSTRACT:
A device for injecting a liquid composition into a plant includes a pair of telescopically associated container sections cooperating to define an interior space whose volume is varied incident to relative axial movement of the sections between extended and contracted positions for purposes of expelling liquid therefrom into a plant through a liquid discharge tube connected to one of the sections, characterized in that the interior space may be selectively employed to store a single liquid chemical composition or divided into separate volumes for storing dissimilar liquid and liquid or solid chemical compositions, which may be mixed within the device immediately prior to injection thereof into a plant.
