| Abstract/Contents: | "A study to evaluate several compounds (sulfometuron methyl, metsulfuron methyl, chlorsulfuron, diclofop, sethoxydim, glyphosate, and RE-40885) for selective control of tall fescue (Festuca arundinacea Schreb.) and orchardgrass (Dactylis glomerata L.) was initiated June 18, 1986. Treatments were applied on June 18, 1986, (except for RE-40885 which was applied July 22, 1986) with repeat application September 26, 1986, to 0.9 by 3.1 meter plots. The design was a randomized complete block design with three replications. Each compound was applied with a hand-held compressed air boom sprayer except for flyphosate which was applied with a wick (Walk-a-Wick, Coolidge, AZ). In addition, one treatment of sulfometuron mehtyl, metsulfuron, methyl, and chlorsulfuron was applied by wick. Injury to tall fescue, orchardgrass and fine textured species, [fine fesuce (Festuca rubra L.) and Kentucky bluegrass (Poa pratensis L.] were rated periodically throughout the study. Percent reduction of orchardgrass and tall fescue clumps was rated on October 31, 1986. Diclofop, sethoxydim and sulfometuron methyl caused the most severe injury to tall fescue. Sulfometuron methyl treated tall fescue sustained the longest injury. Of the chemicals applied, only diclofop did not injure fine textured species. Chlorsulfuron treated turf had intermediate injury on both tall fescue and fine textured grasses. Metsulfuron methyl and RE-40885, had little effect on any of the grasses. Glyphosate also had little effect on the grasses, however, this was due to the application method. Only sulfometuron methyl caused significant reduction in orchardgrass. Diclofop at the high rate caused some injury to orchardgrass, but was significantly less than sulfometuron methyl after the second application. The wick applied treatments, except glyphosate, caused greater injury to all species following the second applicaiton compared to the first. All wick applied materials utilized double the highest sprayer rate. Over the 135 day period, diclofop and sulfometuron methyl were most effective in percent reduction of tall fescue. Only sulfometuron methyl adequately reduced orchardgrass." |
