Abstract
Application costs and efficacy for two concentrations of herbicide and treatment time intervals were determined for cut-stump treatments applied to American beech (Fagus grandifolia Ehrh.) to control root and stump sprouts in central West Virginia. Glyphosate as GlyproTM (53.8 percent a.i.) was applied to the outer 2 inches of beech stumps from trees ≥6.0 inches in diameter at breast height within 0 to 1 and 3 to 4 hours after cutting. In addition, the effects on efficacy of using two concentrations of GlyproTM (50 and 100 percent) were also evaluated. This study demonstrated that a 50-percent solution of GlyproTM was just as effective as a 100-percent solution and that an applicator could wait up to 4 hours after stems had been cut before applying the herbicide, without reducing efficacy.
