• Abstract:
  Research experiments were designed and initiated to evaluate plant growth regulators and recently registered herbicides
  
  for vegetation management along North Carolina roadsides, as well as warm-season turfgrass seed and sod practices to utilize
  
  low-growing, mat-forming species that require reduced inputs. All experiments were repeated in location and/or time, and have
  
  produced three peer-reviewed publications to date in Crop Science or Weed Technology journals. Results from this project
  
  suggest plant growth regulators may be used to reduce annual mowing events, which can result in cost-savings as well as reduced
  
  mowing operator requirements in areas that pose increased safety risks. Greenhouse research identified NC agronomic and
  
  specialty crops that Esplanade (active ingredient: indaziflam), a relatively new PRE herbicide, may be safely applied near without
  
  objectionable drift concerns, while field trials evaluated this herbicide and others for warm-season release programs.
  
  Additionally, greenhouse research confirmed Esplanade and Proclipse (active ingredient: prodiamine) applied PRE provide
  
  excellent annual ryegrass (Lolium multiflorum L.) control. Field research identified herbicide application timings with respect to
  
  season and mowing operations to improve current vaseygrass (Paspalum urvillei Steud.) control programs. Lastly, zoysiagrass
  
  (Zoysia spp.) sodding field trials identified cultivars, planting preparation techniques, and planting timings that resulted in
  
  successful establishment along guardrails, while warm-season turfgrass seeding resulted in unacceptable establishment. This
  
  information may be utilized by the North Carolina Department of Transportation – Roadside Environmental Unit to help improve
  
  comprehensive vegetation management practices that reduce long-term inputs while providing safe thoroughfares for motorists.
