Chemical crop tree release treatments were applied to young hardwood stands at three sites in central West Virginia to evaluate the effectiveness of glyphosate as Accord (41.5% SL), imazapyr as Arsenal AC (53.1% SL) and Chopper (27.6% EC), and triclopyr as Garlon 3A (44.4% triethylamine salt SL), and Garlon 4 (61.6% butoxyethyl ester EC) using hack-and-squirt injection and low volume stem bark band application methods. American beech (Fagus grandifolia Ehrh.) was a major competitor to black cherry (Prunus serotina Ehrh.) crop trees at each site. The treatments were applied in June and evaluated 12 months after treatment. A numerical rating system ranging from 1 to 7 (0?100% crown affected), which utilized visual symptoms, was used to evaluate the efficacy of each treatment. Trees receiving a rating of 5 (75% crown control) or greater were considered controlled.
