| Abstract/Contents: | "A study evaluating glufosinate-ammonium (glufosinate) and pelargonic acid (Scythe₂/]) for total vegetation control along roadsides was initiated as part of a cooperative project between The Pennsylvania State University and The Pennsylvania Department of Transportation. Roadside treatments were applied to 3 by 25 ft plots located along a guiderail near State College, PA, on July 20, 1996; using a CO₂-powered hand held sprayer. To compare any potential differences in spray volumes, 40 GPA and 80 GPA were both applied using either two Spraying Systems OC-04 spray tips at 23 psi or two OC-08 spray tips at 36 psi, respectively. Visual ground cover ratings of annual and perennial weed species were taken July 18, to assess the original weed pressure and July 29, 9 days after treatment (DAT); August 30, 41 DAT; and October 4, 1996, 76 DAT. Predominant weed species were common lambsquarters (Chenopodium album L.), common ragweed (Ambrosia artemisiifolia L.), wild carrot (Daucus carota L.), wild parsnip (Pastinaca sativa L.), spotted knapweed (Centaurea maculosa Lam.), chicory (Cichorium intybus L.), white sweetclover (Melilotus alba Medik.), giant foxtail (Setaria faberi Herrm.), and green foxtail (Setaria viridis L.). The initial green cover ratings were, on average, between 78 and 94 percent for all plots. Glufosinate was the only postemergent product that provided significant early signs of necrosis to the treated plants 9 DAT. By 41 DAT, treatments containing sulfometuron methyl and diuron combined with a postemergent product and imazapyr plus diuron provided significantly better control than all other treatments, with green cover 15 percent or less. Glufosinate alone; glufosinate plus 2, 4-D; glufosinate plus imazapyr; Scythe plus glyphosate; and sulfometuron methyl plus diuron all provided poor control. All treatments began to show an increase in weed pressure 76 DAT. The glufosinate, glufosinate plus 2, 4-D, and glyphosate all continued to show excellent long-term control when used in combination with sulfometuron methyl and diuron. The imazapyr and diuron mix also maintained excellent control at this rating period. Glufosinate, when tank mixed with sulfometuron methyl and diuron, provided statistically similar results at both the 0.5 and 1 lb/a rates. Glyphosate at 2 lb/a performed well at both 41 DAT and 76 DAT when tank mixed with sulfomituron methyl and diuron. Reducing the rate of glyphosate to 1 lb/a and adding Scythe did not significantly reduce control. Treatments 10 and 12 compared Scythe, glyphosate, sulfometuron methyl, and diuron at 40 versus 80 GPA. There was no statistical difference noted at any rating period between these two treatments. If both rapid burndown and long-term control are desired, glufosinate at both 0.5 and 1 lb/a, and glufosinate plus 2, 4-D, when combined with sulfometuron methyl and diuron can be used." |
