Abstract A method for the chemical treatment of living trees is disclosed wherein a chemical agent is injected into the tree in that a cartridge which is at least partially filled with the chemical treating agent is knocked into the tree trunk. The cartridge is ruptured at its end penetrating into the tree by virtue of the impact and there is generated within the cartridge an overpressure which injects the chemical treating agent into the trunk of the tree. There is also disclosed an injection cartridge for carrying out the aforedescribed method which comprises a sleeve member which at least partially contains or is filled with the chemical treating agent, and wherein the end of the sleeve member destined to be knocked into the tree trunk supports a closure member which is destructible under the impact force.

Claim 1
Independent Claim
178 words
An injection assembly to be driven into a tree for treatment of living trees through the injection of a chemical treating agent contained therein comprising the combination of: a tube having a closed end and an open end, wherein the edge of said tube at said open end is sharpened for easy entrance into the tree; a chemical treating agent partially filling said tube; closure means for maintaining said chemical treating agent within said tube, said closure means being destructible on contact with the tree; means for driving said open end of said tube into the tree and expelling the chemical agent into the tree, wherein said means for driving includes a member movable in the direction of the tree, and a bore located in said member on the side of said member facing the tree, said bore having a length less than the length of said tube and carrying said tube therein with said open end protruding from said bore; wherein said closure means comprises an ampoule located within said tube and containing said chemical treating agent.
