Applications of Roundup, a glyphosate, by mistblower were effective in controlling hay-scented fern, blackberries, and some tree, shrub, and herbaceous species on an experimental watershed in West Virginia. Damage to planted Norway spruce was slight at rates of 1, 2, and 3 qt/acre (0.75, 1.50, and 2.25 lb/acre of the acid glyphosate). A variety of hardwood species were killed following injections of 20 or 50 percent solution of Roundup at a rate of 1.5 ml per incision. The cuts were spaced at 1.5 inches, edge to edge, around the stem near groundline. Resprouting of the treated hardwoods was minimal after 2 years.
