Sequential Postemergence Applications for the Control of Yellow Nutsedge in Bermudagrass Turf

Masoumeh Sadi and Saeed Saeedipour

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 m–2) and untreated plots (130 g m–2), 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.
