Abstract

Oxadiazon [2-tert-butyl-4(2,4-dichloro-5-isopropoxyphenyl)-Δ2-1,3,4-oxadiazolin-5-one] at 2.2 to 4.4 kg/ha controlled goosegrass [Eleusine indica (L.) Gaertn.] without injuring bermudagrass [Cynodon dactylon (L.) Pers.], but severely injured overseeded common ryegrass (Lolium multiflorum Lam. common) and perennial ryegrass (Lolium perenne L. ‘Medalist VI′) for a 5 – to 6-week period after treatment in the spring and thus reduced turf quality. The transition was poor because ryegrass was killed faster than bermudagrass could initiate new spring growth. The combination of bensulide [O, O-diisopropyl phosphorodithioate S-ester with N-(2-mercaptoethyl)benzenesulfonamide] and oxadiazon applied as a single treatment at 6.7 + 1.7 kg/ha controlled goosegrass as effectively as did oxadiazon applied alone at 2.2 kg/ha or higher rates and did not injure the turf, so the transition from cool-season grass to bermudagrass was uniform. Aeration of an overseeded bermudagrass turf after applications of oxadiazon did not significantly decrease goosegrass control.
