The method employs a lengthy cone shaped vessel to be filled with the liquid chemical and capped with a cap for the filled vessel to be inserted in a hole bored in a target tree. The tip of the vessel is cut before insertion in the hole to allow the liquid discharge from the vessel into the tree. The cap has a flat top for easy hammering for insertion. The chemical is injected to prevent flower or seed fluffs from flying which cause health hazards.
