Dutch Elm Disease Control: Economics of Girdling Diseased Elms to Improve Sanitation Performance    (View PDF)

William N. Cannon, Jr., Jack H. Barger and David P. Worley

Abstract: Early detection and immediate girdling plus prompt removal (within 20 work days) of diseased elms saved more elms at a lower cost than sanitation practices in which diseased elms were just removed promptly or were allowed to remain standing into the dormant season. A 5-year case history demonstrated savings of 25 percent in total cost and an additional 163 elms per thousand.
