ABSTRACT:
An apparatus and method for injecting liquids directly into the stem or trunk of a plant. The apparatus includes a container for holding liquid, an injection device and a conduit extending between and connected to the container and the injection device. Mounted on the injection device is a tapered, wedged-shaped needle having an outer surface, a liquid-conducting needle conduit and at least one ejector hole extending between the outer surface of the needle and the needle conduit whereby liquid may be transferred from the needle conduit to the outer surface of the needle. Liquid may thus be transferred from the container through the conduit to the injection device, through the needle and out of an ejector hole onto the outer surface of the needle for injection into the stem or trunk of a plant. The method of the present invention includes the steps of providing an apparatus as described above, inserting the needle into the stem or trunk of a plant such that the ejector holes are located interiorly of the outer surface of the stem or trunk, engaging the injection device and injecting the liquid into the stem or trunk of a plant in response to engagement of the injection device. Liquid is thus transferred from the container through the conduit, through the injection device, through the needle conduit and out the ejector hole thereby being deposited in the stem or trunk of the plant. The needle is then removed from the stem or trunk of the plant.
