| Abstract/Contents: | "North Carolina Department of Transportation (NC DOT) currently maintains over 330,000 acres of roadside turf. Of that acreage, 65% is comprised of either Kentucky 31 tall fescue or bahiagrass, species with unsightly foliar growth and seedheads. This excessive growth and seedhead production is also responsible for many accidents due to reduced visibility. In an effort to reduce the annual operating budget, NC DOT is transitioning new and existing roadsides to alternative species. These species include centipedegrass (Eremochloa ophiuroides) and zoysiagrass (Zoysia japonica) which possess lower foliar and seedhead heights. With increased use of these species into existing roadsides, herbicide and plant growth regulator (PGR) tolerance is uncertain. Trials were initiated to investigate the tolerance of centipedegrass at various timings. The trials were conducted using a randomized complete block design over several timings including PRE seeding, at planting, and early post treatments. Products evaluated included atrazine (Aatrex), mefluidide (Embark), clethodim (Envoy), metsulfuron (Escort), sulfometuron (Oust), imazapic (Plateau), simazine (Princep), chlorsulfuron (Telar), and sethoxydim (Vantage). Applied prior to planting of centipedegrass, sulfometuron (0.5 and 1 oz) were the only treatments to produce significant phytotoxicity. When applied at planting of centipedegrass, imazapic (6 oz), sulfometuron (0.5 oz), metsulfuron (0.5 & 1 oz), and chlorsulfuron (0.125 oz) + mefluidide (0.5 pt) caused a reduction in cover. Applied early post to 1 leaf to 1 tiller centipedegrass, chlorsulfuron (0.125 oz) + mefluidide (0.5 pt), sulfometuron (0.5 & 1 oz), and metsulfuron (1 oz) grew out of this injury by 69 DAT." |
