| Abstract/Contents: | "Crabgrass (Digitaria sp.) is arguably the most problematic weed in turfgrass. Many pre and postemergence herbicide control options are available, but few include broadleaf activity. In summer 2007, F7214 and F7651, experimental herbicides developed by FMC, were evaluated in turfgrass at Virginia Tech. Our objectives were to determine perennial ryegrass (Lolium perenne) and Kentucky bluegrass (Poa pratensis) tolerance, and smooth crabgrass (Digitaria ischaemum) and white clover (Trifolium repens) control by F7214 and F7651 compared to quinclorac. Two trials were initiated on Kentucky bluegrass (KBG) and perennial ryegrass (PR) maintained at fairway height (2 cm). Smooth crabgrass plants ranged from 4 to 8 tillers at time of application. The trials were located at Virginia Tech's Glade Road Research Facility in Blacksburg, VA. Trials were established on July 26, 2007. Experiments were arranged in a RCBD with three replications, and 1.8 by 1.8 meter plots. Treatments included single applications of F7651 at 0.14, 0.28, and 0.42 kg ai/ha, F7214 at 0.56, 0.84, 1.12, 1.40, and 1.68 kg ai/ha plus 0.25% NIS, and quinclorac at 0.42, 0.84, and 1.12 kg ai/ha plus 0.25% NIS, and a nontreated check. F7651 treatments alone did not control smooth crabgrass at either location, but resulted in 43 and 78% control of white clover at the 0.42 kg ai/ha rate in KBG and PR, respectively. F7214 treatments resulted in 76 to 98%, and 91 to 98% control of smooth crabgrass and 100% control of white clover in KBG and PR, respectively. Quinclorac resulted in 68 to 90%, and 61 to 93% control of smooth crabgrass, and 100% control of white clover in KBG and PR, respectively. None of the herbicide treatments caused injury to the turfgrass species tested. F7214 controlled smooth crabgrass and white clover better than F7651, and equivalent or better than the quinclorac comparison treatments." |
