| Abstract/Contents: | "Centipedegrass (Eremochloa ophiuroides) is a warm-season turfgrass species which was introduced from China in 1916. Furthermore, centipedegrass has attributes that make it appealing for use along roadsides in North Carolina. Attributes include reduced foliar height compared to tall fescue (Festuca arundinacea) and inconspicuous seedheads. When centipedegrass is established along roadsides, these properties allow reduced maintenance costs due to reduced mowing cycles and reduced plant growth regulator requirements, as compared to tall fescue and bahiagrass (Paspalum notatum). Although centipedegrass is well-suited for use along roadsides in North Carolina, establishment of centipedegrass is much slower than most warm-season turfgrass species. Furthermore, weed control in centipedegrass poses a unique situation. In many cases, once centipedegrass is established, no weed control practices are needed due to minimal weed infestations; however, registered herbicides option are available for grass and broadleaf weed control in established centipedegrass. However, no registered herbicide options are available during the establishment of seeded centipedegrass. Further, if no weed control program is implemented, weeds are able to outcompete centipedegrass delaying grow-in and reducing winter survival. Trials were initiated to investigate the effect of atrazine applied at centipedegrass seeding in the presence of large crabgrass (Digitaria sanguinalis) and centipedegrass tolerance to herbicides and plant growth regulators applied at seeding. When atrazine (1100 g ai/ha) was applied at seeding, large crabgrass emergence was reduced (48%) compared to the control (89%). Further, centipedegrass tiller production and ground cover were reduced linearly with increasing amounts of large crabgrass; however, tiller production and ground cover were reduced less when atrazine was applied at seeding confirming atrazine applied at seeding can hasten centipedegrass grow-in. When applied at seeding of centipedegrass, imazapic (18 or 35 g ai/ha), atrazine (1100 or 2200 g ai/ha), or simazine (1100 or 2200 g ai/ha) did not reduce centipedegrass ground cover compared to the nontreated at any observation date. However, sulfometuron (53 g ai/ha) or metsulfuron (21 or 42 g ai/ha) reduced centipedegrass ground cover compared to the nontreated at each observation date." |
