• 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.
