  • Abstract:
    Research experiments were designed and initiated to determine if application placement technologies offer ; a viable solution for vegetation management along North Carolina Roadsides. Select equipment was evaluated for ; broomsedge (Andropogon virginicus) control in centipedegrass rights of way as well as for plant growth regulator ; applications along tall fescue (Festuca arundinacea) or bahiagrass (Paspalum notatum) roadsides in North Carolina. ; Research experiments were repeated in time. Evaluated application placement technologies included equipment ; which incorporated mowing into the pesticide or plant growth regulator application as well as equipment that only ; wiped the foliage. ; Much important data were collected and will aid in devising a more complete vegetation management ; program for North Carolina Roadsides. Additionally, through this research, control options which incorporate ; application placement technologies were identified for broomsedge control along North Carolina roadsides. This is ; extremely important for NC DOT as control options had not been identified prior to completing this research. ; It appears Burch Wet Blade (also known as Diamond Wet Blade) would be the best fit for broomsedge control along ; centipedegrass roadsides in North Carolina. With glyphosate (2 qt/a) applied through Burch Wet Blade at one ; gallon per acre mown at four inches, we were able to obtain 90% broomsedge control through one year after ; treatment. As for plant growth regulator applications along tall fescue or bahiagrass roadsides with application ; placement technologies, in no instance were application placement technologies advantageous to a conventional ; broadcast spray application. These data indicate application placement equipment would be beneficial to certain ; aspects of vegetation management along North Carolina roadsides.
