Yes…and you can treat firs, spruces, evergreens, Scots pine trees (Scotch pine), hemlocks, palms and more. ArborSystems specially-designed Portle Tips and Tip Setter places the chemical into the active areas where it can be easily absorbed. The Portle Tip has openings, or ports, along the length of the tip which inject chemical at multiple locations. A check valve in the hub of the tip keeps chemical in the tree while all injections are being made. Portle Tips are also useful for injecting difficult-to-treat hardwoods or when making large-volume injections (such as for Dutch Elm disease or Oak Wilt) or late season injections when most trees are harder to penetrate.
