Abstract/Contents:"Bermudagrass turf is commonly overseeded with perennial ryegrass during winter dormancy to provide improved aesthetics. Several herbicides are available for controlling the perennial ryegrass during spring transition back to a bermudagrass monoculture. QualiPro recently received registration for Negate Herbicide, which will be the first transition-assisting herbicide comprised of two sulfonylurea active ingredients. It will be marketed for use in warm-season turfgrass for controlling cool-season grass weeds and a broad spectrum of broadleaf weeds. The objectives of this study were to evaluate Negate compared to industry standards foramsulfuron, trifloxysulfuron, and flazasulfuron for perennial ryegrass and broadleaf control during spring transition. Three studies were conducted in a randomized complete block design and initiated on May 22, 2009 and April 20, 2010 in North Carolina, and May 16, 2012 in Virginia. Golf fairway turf consisting of bermudagrass overseeded the previous fall with perennial ryegrass was used for these experiments. Plots were 2 m by 2 m and treated with CO2 pressurized sprayers to deliver 280 L/ha at 262 kPa using Visiflo Flat Fan or Turbo Tee Jet 11004 nozzles. Herbicides included metsulfuron, rimsulfuron, Negate, flazasulfuron, foramsulfuron, and trifloxysulfuron applied once at 21, 18, 40, 26, 28, and 18 g ai/ha, respectively. Weed control and bermudagrass injury was visually estimated as a percentage of untreated turf. Bermudagrass was not injured by any treatment at any site. Negate and industry standards foramsulfuron, flazasulfuron, and trifloxysulfuron completely controlled perennial ryegrass and annual bluegrass by 21 DAT at all three sites. Metsulfuron failed to control annual bluegrass at one site. All treatments controlled white clover and dandelion 90% or greater. Negate, trifloxysulfuron, metsulfuron, rimsulfuron, and flazasulfuron controlled prostrate knotweed at least 97% and more than foramsulfuron, which controlled prostrate knotweed 40%. Based on these data, Negate appears to be a viable option for weed control and perennial ryegrass transition and could offer an improved broadleaf weed control spectrum compared to industry standards. More work is needed to better assess the range of broadleaf weeds controlled by Negate compared to standard transition-assisting herbicides."
