Abstract
Experiment was conducted in 2013 to evaluate various herbicide treatment regimes for POST yellow nutsedge control. Evaluated herbicides included metsulfuron-methyl+sulfosulfuron, Oxadiazon, Clothedim, Sicloxidim, Nicosulfuron+Rimsulfuron and untreated check. Evaluated treatments did not cause objectionable bermudagrass injury at any time. The highest and the lowest dry weight of turfgrass was achieved in Oxadiazon (211 g mG2) and untreated plots (130 g mG2), respectively. The results of this study indicate that satisfactory control of yellow nutsedge (>90%) obtained by post-emergence application of oxadiazon, clothedim or sicloxidim at the first time and repeat applications will not be required. Further, our results indicate that efforts to enhance yellow nutsedge control with metsulfuron-methyl+sulfosulfuron and nicosulfuron+rimsulfuron timings and repeat applications were inconsistent. These data confirm that the lower bermudagrass phytotoxicity was achieved with the sicloxidim treatment.
2013年通过试验,评价了不同除草剂处理方案对后黄芩的防治效果。评价除草剂包括甲磺隆-甲基+磺磺隆、恶二唑、Clothedim、Sicloxidim、nico磺隆+ rim磺隆和未经处理的检查。评估的处理在任何时候都没有造成令人反感的百慕大草损伤。草皮干重以恶二唑处理(211 g mG2)和未处理(130 g mG2)的草皮干重最高和最低。本研究结果表明,萌发后第一次施用恶二唑、clothedim或sicloxidim,可获得满意的防治效果(>90%),不需要重复施用。此外,我们的研究结果表明,甲磺隆-甲基+磺胺磺隆和尼科磺隆+利姆磺隆的施用时间和重复施用效果不一致。这些数据证实,在西氯西汀处理下,百慕大草的植物毒性较低。
