Wound Dressings on Red Maple and American Elm: Effectiveness after Five Years    (View PDF)

Alex L. Shigo and Charles L. Wilson

Abstract: Closure and internal compartmentalization of wounds on red maple and American elm were not stimulated by dressings of an asphalt-based material, orange shellac, or polyurethane varnish. After 5 years, decay fungi had infected many treated and control wounds. Some trees closed woun­ ds rapidly; others closed wounds slowly regardless of the treatments.
