ABSTRACT:
The two piece tree syringe of the present invention can be used to inject a liquid agent into the living tissue of a tree. This tree syringe includes a barrel and a plunger. An hollow injection stem projects from the barrel. A passageway inside the hollow injection stem is separated from the interior of the barrel by a thin membrane in the barrel floor. The plunger is a double walled cylindrical container adapted to engage the barrel in a telescoping fashion. The drain stem is fixed to the inner wall of the plunger and can line up with and pierce the thin membrane in the barrel floor so that it can pass through the barrel floor and into the injection stem passageway. After the tree syringe is partially assembled and partially filled with a liquid agent, it is inserted into a hole drilled into the living tissue of a tree and compressed until the drain stem punctures the thin membrane in the barrel floor thus opening a passageway for almost all of the pressurized liquid agent to escape out through the injection stem and into the tree.
