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.
