| Abstract/Contents: | "Metamifop is a potential new graminicide for selective weed control in cool season turfgrass. Only a few research trials have evaluated metamifop on turfgrass in the US. Initial reports indicated excellent cool season turfgrass tolerance and control of a variety of grass weed species. Fenoxaprop has the same mode of action as metamifop and is one of only four herbicides currently registered for postemergence grass weed control in turfgrass. One of the four registered herbicides, MSMA, is soon to be excluded from turfgrass uses, so any herbicide registered to control grass weeds in turfgrass postemergence would be welcome. Several studies were conducted in 2009 to evaluate tolerance of creeping bentgrass (Agrostis stolonifera) putting green and Kentucky bluegrass (Poa pratensis) fairways and control of smooth crabgrass (Digitaria ischaemum) and yellow foxtail (Setaria glauca). All trials were arranged as randomized complete block designs with three replications. On two golf putting greens, metamifop at 200 g ai/ha failed to control smooth crabgrass but 300 g ai/ha or more controlled smooth crabgrass 90% or greater, and equivalent to fenoxaprop at 100 g ai/ha 4 and 6 weeks after treatment (WAT). Repeated application of 200 or 300 ai/ha completely controlled smooth crabgrass. At fairway mowing height, only 300 and 400 g ai/ha controlled smooth crabgrass and yellow foxtail when applied once or twice. The only turfgrass injury noted in these trials, due to metamifop, occurred when 400 g ai/ha was applied to creeping bentgrass putting green turf and did not exceed 10%. Fenoxaprop did not injure fairway Kentucky bluegrass but completely killed creeping bentgrass putting green turf when applied at 100 g ai/ha." |
