Herbicide Treatment of Striped Maple and Beech in Allegheny Hardwood Stands
Abstract:Three small-plot experiments evaluated herbicides for killing striped maple (Acer pensylvanicum L.) and beech (Fagus grandifolia Ehrh.). Glyphosate, applied to striped maple or beech in uncut stands, from June 1 to October 1, produced a high degree of kill at rates of 1.12 to 4.48 kg/ha a.i. (active ingredient). At the 1.12 kg/ha rate, kill varied with time of application. Best kill was with the July 1 through September 1 application dates for striped maple and with the August 1 through October 1 application dates for beech. Applications of 2,4,5-T in an uncut stand, at rates ranging from 0.78 to 4.70 kg/ha a.i., killed at least 97 percent of the striped maple. Applications of 2,4,5-T did not interfere with subsequent development of desirable species of advance reproduction. Bromacil (8.96 to 53.76 kg/ha a.i.), 5 percent picloram pellets (1.68 to 12.10 kg/ha a.i.), and 10 percent picloram pellets (2.24 to 17.92 kg/ha a.i.) were applied to striped maple in a 12-year-old clearcut. About 90 percent of the striped maple were killed with all rates of bromacil, rates of 6.72 kg/ha a.i. or more of 5 percent picloram pellets, and 8.96 kg/ha a.i. or more of 10 percent picloram pellets. Survival and height growth of white ash (Fraxinus americana L.) seedlings subsequently planted on the site were not significantly reduced by any rate of application of any of the herbicides.
