| Abstract/Contents: | "'Tifway' bermudagrass is a fine textured warm-season turfgrass widely used on lawns, sports fields, fairways and tees in the Southern United States. Fragrant kyllinga (Kyllinga odorata ) is a bunch type warm season annual that thrives in moist low mowed areas such as these. Kyllinga is a weed that competes with the 'Tifway' bermudagrass during the warm season. The object of this study was to evaluate the efficiency of various commercial and experimental herbicides for Fragrant kyllinga control in 'Tifway' bermudagrass. Two studies were conducted at Clemson University. The treatments for study one were applied in June and the treatments for study two were applied in August. Study one investigated Manage (halosulfuron) at various levels, Image (imazaquin) and an experimental formulation of sulfosulfuron designated as MON-44951. Study two investigated the efficiency of Manage, Basagran (bentazone), Manor (metsulfuron), TranXit (rimsulfuron) and the sulfonylureas trifloxysulfuron (Monument), flazasulfuron, foramsulfuron and sulfosulfuron. The studies subjectively determined the control of kyllinga on a percentage scale with 100% designated as complete control and 90% being considered acceptable control. Both of the studies were designed as randomized complete block arrangements with each individual plot measuring 2.0 m x 1.5 m. The blocks were each replicated a total of three times and were maintained at a mowing height of 1.27 cm. The treatments were applied using a CO2 backpack spray boom calibrated at 187 l/ha (20 ga l/A). Treatments for study one were applied on June 26 2002 with sequential applications on August 7, 2002. Treatments for study two were applied on August 12, 2002. In study one, sulfosulfuron between 0.05 lb ai/A and 0.14 lb ai/A provided greater than 90% control of kyllinga 14 weeks after the treatment , the 0.07 lb ai/A rate provided unacceptable control. Sulfosulfuron at 0.05 lb ai/A and sulfosulfuron at 0.07 lb ai/A followed by a sequential application of 0.05 lb ai/A provided 100% control of the kyllinga. Acceptable control (>90%) was provided by Manage at 0.06 lb ai/A; 0.03 lb ai/A followed by a sequential application at 0.03 lb ai/A; and 0.06 lb ai/A followed by a sequential application at 0.06 lb ai/A but not at 0.03 lb ai/A. In study two, trifloxysulfuron applied at 0.3 lb ai/A provided 100% control of kyllinga at the end of the study. Acceptable control of kyllinga was provided by MSMA, MSMA and Image and flazasulfuron seven weeks after the treatment. All other treatment provided less than 75% control of the kyllinga. Best kyllinga control was provided by sulfosulfuron at 0.05 lb ai/A followed by a sequential application at 0.05 lb ai/A and sulfosulfuron at 0.07 lb ai/A followed by a sequential application at 0.05 lb ai/A. Multiple Manage and MSMA treatments also provided good control. Future research in this area may include adju sting the rates, timing, and tank mixes of the herbicides. Further work could be put into observing these herbicides control of other problematic weeds. It would also be of benefit to investigate further into the use of sulfonylureas for kyllinga and sedge control." |
