| Abstract/Contents: | "Flazasulfuron is a new sulfonylurea herbicide that will soon be registered for use in U.S. turfgrass markets. Flazasulfuron provides rapid control of perennial ryegrass, tall fescue and other cool-season grasses, as well as, control of sedge and various broadleaf weeds. Although much is known about how flazasulfuron performs in turfgrass when applied alone, few studies have evaluated tank mixture combinations with flazasulfuron and other herbicides. Studies were conducted near Richmond and Martinsville, VA to evaluate flazasulfuron alone or mixed with various broadleaf herbicides for prostrate knotweed (Polygonum aviculare) control and flazasulfuron applied sequentially or with various preemergence and postemergence grass herbicides for false green kyllinga (Kyllinga gracillima) control. Studies were conducted as randomized complete block designs with four replications on golf course roughs. Prostrate knotweed was evaluated at one site at Hanover Country Club (HCC), near Richmond and false green kyllinga control was evaluated at three sites; two at HCC and one at Chatmoss Country Club(CCC) near Martinsville, VA. Treatments for prostrate knotweed control included a 2 X 7 factorial arrangement of flazasulfuron at 1.0 and 1.5 oz/A applied in all combinations with the following tank mix options: nothing, quinclorac (Drive™) at 1.0 lb/A, triclopyr + clopyralid (Confront™) at 1.5 pt/A, 2,4-D + dicamba + MCPP + carfentrazone (Speedzone™) at 4 pt/A, carfentrazone (Quicksilver™) at 1.5 fl oz/A, metsulfuron (Manor™) at 0.5 oz/a, and primisulfuron at 1.0 oz/A. Initial treatments for prostrate knotweed were applied on April 28, 2005. False green kyllinga treatments included dithiopyr (Dimension™ Ultra) at 20 oz/A, prodiamine (Barricade™) at 2.3 lb/A, pendimethalin (Pendulum Aquacap™) at 4.2 pt/A, Drive at 1.0 lb/A, and fenoxaprop (Acclaim Extra™) at 3.5 oz/A all applied alone or mixed with flazasulfuron at 1.5 oz/A. Comparison treatments included a nontreated control, flazasulfuron applied twice at 1.5 or 3.0 oz/A, halosulfuron (Manage™) at 1.0 oz/A, and MSMA applied twice at 40 oz/A. Initial treatments for false green kyllinga were applied on June 7 and 30, 2005 at HCC and August 12, 2005 at CCC. Broadleaf herbicides did not reduce flazasulfuron efficacy for prostrate knotweed control. Flazasulfuron controlled prostrate knotweed 75% early season and 80% late season. Initial control was increased by addition of Speedzone™ or Quicksilver™ but late season control was equivalent between treatments. False green kyllinga control was consistent between the three locations and data were pooled. Flazasulfuron applied twice at either rate and MSMA applied twice completely controlled false green kyllinga while Manage™ applied once did not. Any tank mix combination that contained flazasulfuron controlled false green kyllinga at least 98% in a single treatment, except flazasulfuron + Drive, which controlled false green kyllinga 90%. Tank mix herbicides did not control false green kyllinga greater than 30% when flazasulfuron was not included. These data suggest that sedge and broadleaf control with flazasulfuron is unlikely to be reduced by tank mixtures with the herbicides evaluated." |
