Abstract: Four herbicides (Accord, Accord+Escort, Garlon/ Tordon, and Krenite) and two cutting regimens (cut/spray and cut/delay spray) were tested in an Ohio power-line corridor. In all herbicide/cutting combinations, tree populations showed some recovery two years after treatment. Although Accord+Escort applied in a cut/spray treatment resulted in the lowest population of trees after two years, this treatment also had the most persistent negative effect on non-target ground cover. Krenite had the least negative impact on ground-cover. Spraying sooner rather than later after cutting improves treekill by all herbicides, but may also increase effects on nontarget species. More selective herbicides and herbicide application methods are needed for management of natural vegetation.
