ABSTRACT:
A self-tapping applicator head for chemical injection treatment of trees comprises a socket and a tapered integrally formed and exteriorly threaded shank portion. A centrally-defined hole or passageway extends substantially the length of the shank portion, connecting the tip of the shank with the socket. The tip portion of the shank has a plurality of output orifices defined therein and oriented transversely in communicating relationship with respect to the central passageway. The socket is provided with a centrally defined interiorly threaded hole, which has a diameter substantially greater than the diameter of the shank passageway, and which matingly receives the male fitting at one end of a separate, pressurized hose line. Pressurized chemicals delivered to the socket fitting are forced through the nozzle shank output orifices into the sapwood portion of the tree with the sealing effect of the tapered nozzle preventing leakage therearound. The method comprises the steps of drilling a hole in the trunk of the tree to be treated, inserting the aforementioned applicator by threaded rotation of same until the shank tip penetrates the tree sap line, and applying chemicals under pressure via a line connection to the nozzle head.
