Abstract
A method of introducing treatment agents comprising medicine or nutrients into a tree, involving the boring of holes above ground into the trunk of the tree. Homogeneous plugs of solidified polyethylene glycol (PEG) with such treatment agents mixed therein are molded and inserted into the holes in the tree trunk and sealed with wax. The dissemination time of the treatment agent into the tree trunk is controlled by selection of the PEG's used, with higher molecular weights PEG's taking longer to dissolve and disseminate the treatment agent into the transpirational flow of the tree being treated than the lower molecular weight PEG's. The method leaves no foreign material such as plastic casings or cartridges within the tree trunk after treatment.
