Impact of Burning, Cutting, and Chemicals on the Spreading of Virginia Creeper (Parthenocissus quinquefolia)

Field experiments were conducted in Beijing to study the impact of burning, cutting, and chemicals treat on the spreading of Virginia creeper (Parthenocissus quinquefolia). Groundcover and growth vigiour were determined after treatments to assess control efficacy. It was indicted that burning in the early spring could reduce groundcover up to 36.2% in average 30 d to 60 d after burning;Cutting at the basement(0 cm), 20 cm or 40 cm of stem decreased groundcover by 38.2%, 26.7% or 21.9% 50 d after cutting respectively. Applied glyphosate at 1 500 g·hm-2alone or combined 100 g·L-1 glyphosate (750 g·hm-2) with 100 g·L-1 sulfometruon-methyl(75 g·hm-2)strongly inhibited the growth of Parthenocissus quinquefolia,the control efficacy was up to 24%～38%.It was concluded that the risk of Parthenocissus quinquefolia could be managed by using burning, cutting, and some chemicals.
