| Abstract/Contents: | "A study evaluating imazameth 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 May 8, 1997. The study was arranged in a randomized complete block design with three replications. The treatments were applied using a CO₂-powered hand held sprayer equipped with two Spraying Systems OC-04 spray tips, delivering 35 GPA at 28 psi. All treatments, except those with glyphosate, contained 0.25% (v/v) methylated seed oil and all contained 0.25% (v/v) Polytex A1001 drift control agent. Green cover ratings of weed species were taken May 16, 8 days after treatment (DAT); June 26, 49 DAT; September 2, 117 DAT; and October 6, 151 DAT. Predominant weed species were wild carrot (Daucus carota L.), spotted knapweed (Centaurea maculosa Lam.), white sweetclover (Melilotus alba Medik.), crownvetch (Coronilla varia L.), and western salsify (Tragopogon dubius Scop.). The initial rating 8 DAT showed there were no significant differences among the treatments with average green cover ratings between 55 and 70 percent for all plots. Imazameth or glyphosate alone; and imazameth plus pendimethalin did not provide any lasting control of the weeds in the plots at the rates tested. At all four rating dates there was no difference in green cover between these treatments and the untreated check. The remaining treatments provided good season long control. There were no statistically significant differences noted among these treatments at any of the rating periods. Any of these treatments could be used to provide effective post emergence and long-term residual control of a variety of weeds in a roadside environment." |
