Abstract/Contents:"The control of weeds during the first growing season after centipedegrass [Eremochloa ophiuroides (Munro) Hack.] sprigging is a major problem for most homeowners. Field and greenhouse experiments were conducted on the effects of herbicides applied at different time intervals during the establishment of centipedegrass on weed control and rate of turfgrass cover. The soil type was either a Cecil sandy loam (member of the clayey, kaolinitic, thermic family of Typic Hapludult) or Cecil sandy clay loam. The survival of centipedegrass sprigs was as good with single applications of DCPA (dimethyl tetrachloroterephthalate) at 11.2 kg/ha, atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino-s-triazine], at 1.1 kg/ha, simazine [2-chloro-4,6-bis(ethylamino)- s-triazine], at 1.1 and 2.2 kg/ha, and oxadiazon [2-tert- buty-4-(2,4-dichloro-5-isopropoxyphenyl)-Δ2 -1,3,4-oxadiazolin-5-one], at 3.4 kg/ha, applied immediately after sprigging as in untreated plots. The turfgrass cover at the end of the growing season was as good or better in single treated plots as in multiple treated plots. Repeated applications of atrazine, simazine, and oxadiazon increased the control of large crabgrass [Digitaria sanguinalis (L.) Scop.] and goosegrass [Eleusine indica (L.) Gaertn.] when compared with the control in single treated plots. These results indicate that complete weed control is not necessary for optimum centipedegrass cover during the first season after sprigging."
