| Abstract/Contents: | "Three field experiments were conducted at the Berks Campus of the Pennsylvania State University, Reading, PA, to evaluate the effects of applying pyraflufen-ethyl (ET Herbicide/Defoliant 0.208L) in a tank-mix with a three-way herbicide (2,4-D 2.44L, MCPP 1.3L, and dicamba 0.22L) or glyphosate (Roundup Pro 4L) or glufosinate-ammonium (Finale 1L). All experiments were conducted from May through July 2004, and all herbicide products were applied only once according to standard label rates. In all three test sites, the low maintenance turf stand consisted of a mixed population of Kentucky bluegrass (Poa pratensis), tall fescue (Festuca arundinacea), orchardgrass (Dactylis glomerata), and nimblewill (Muhlenbergia schreberi), and was mowed periodically to a height of 3.5 inches with a rotary mower and clippings were not removed. The target broadleaf weeds present at two of the sites were broadleaf plantain (Plantago major), common dandelion (Taraxacum officinale), and white clover (Trifolium repens). Therefore, two field experiments evaluated the three-way herbicide and pyraflufen-ethyl for broadleaf weed control, and the third field experiment evaluated glyphosate or glufosinate-ammonium and pyraflufen-ethyl for non-selective turf control. In each experiment, all treatments were repeated three times and arranged as a randomized complete block design. Individual plots measured 2.5 x 5 ft. All treatments were applied with a CO2 pressurized backpack sprayer calibrated to deliver 1.0 gal water per 1000 sq ft (44 gal water per acre) at 30 psi from single 8004E flat-fan nozzle. Percent target weed on turf plot-area-cover, phytoxicity, and control were determined on a visual 0 to 100% linear scale. Data were subjected to analysis of variance and treatment means were separated by Fisher's Protected Least Significant Difference test at P 0.05. In the two broadleaf weed control experiments, no antagonism or decrease in weed control efficacy was observed in plots treated with pyraflufen-ethyl tank-mixed with the three-way herbicide. By 7 DAT, the broadleaf weeds were slightly injured from pyraflufen-ethyl but did recover by the end of the experiments at 56 DAT. By 14 DAT, broadleaf weeds treated with pyraflufen-ethyl plus the three-way herbicide exhibited alone. By 56 DAT, however, similar levels of broadleaf weed control were observed in plots treated with pyraflufen-ethyl plus the three-way herbicide or the three-way herbicide alone. In the non-selective turf control experiment, a slight but inconsistent improvement in turf control was observed in those plots treated with pyraflufen-ethyl in combination with glyphosate or glufosinate-ammonium versus plots treated with glyphosate alone or glufosinate-ammonium alone." |
