Hack-and-squirt injection treatments were applied to individual striped maple (Acer pennsylvanicum L.) stems and to the largest stem in sprout clumps in a 25-year-old clearcut in central West Virginia to evaluate seasonal efficacy of imazapyr as Arsenal (28.7%) and glyphosate as Glypro Plus (41.0%) in water carriers. Complete control of injected stems was achieved with all treatments. However, the Arsenal treatments resulted in greater control of basal sprouting, untreated striped maple stems, and sprout clumps. Treatment efficacies were higher in September than in June. Land managers can use the application methods described here and a 6% solution of Arsenal to effectively control individual striped maple stems and sprout clumps.
