ABSTRACT:
An injection capsule to treat trees and woody plants comprising a receptacle portion to hold a chemical to treat trees and woody plants. The receptacle portion has a closed end and an open end, the closed end being formed with a bore extending internally through the receptacle portion from the closed end to the open end. The bore houses a screw fastener, movable along the length of the bore and guided by the walls of the bore, to allow the injection capsule to be attached to a tree or woody plant. The bore is formed with a narrowed diameter section to limit the travel of the screw fastener as it is pushed through the internal bore and driven into a tree or woody plant in order to hold the open end of the injection capsule tightly against the tree or woody plant.
