Cut stump and basal bark studies for Chinese privet (Ligustrum sinense Lour.) control were conducted in Auburn, AL. Treatments for the cut stump application consisted of: 1) 25% vol/vol of an amine formulation of triclopyr (Garlon 3A) at 90 g/L, 2) 25% vol/vol of glyphosate (Accord Concentrate) at 120 g/L, and 3) cutting only with no herbicide (the control) and basal bark treatments consisted of 1) untreated control, 2) Pathfinder II (90 g/L), 3) Garlon 4 at 5% (24 g/L), 4) Garlon 4 at 10% (48 g/L), and 5) Garlon 4 at 20% (96 g/L vol/vol). For the cut stump treatment, both herbicides were effective at controlling Chinese privet with < 12% of the stumps exhibiting any sprouting. For the basal bark application, all herbicide treatments were effective, averaging one new sprout per privet clump with a mean percent defoliation of ≥ 97%.
