Economic Effectiveness of Operational Therapeutic Pruning for Control of Dutch Elm Disease    (View PDF)

F. A. Baker and D. W. French

Abstract: Therapeutic pruning for Dutch elm disease control has not been widely used in Minnesota because of fear of low success, operational difficulties, and difficulty in obtaining funds for such a program. We report a study in which trees were identified for pruning during routine tree inspections, and pruned by contractors. Of 32 pruned trees, 8 have died. Had trees not been pruned, removal costs would have been $5351. The pruning and removal of trees which died subsequently cost $1856. The pruning program reduced the Dutch elm disease program budget in participating communities, and prolonged the life of the pruned elms.
