| Abstract/Contents: | "Large crabgrass [Digitaria sanguinalis (L.)] and goosegrass [Eleusine indica (L.) Gaertn.] are predominant summer weeds in most turfgrasses. A system for chemically controlling these weeds in late spring and early summer with the least amount of herbicide and labor is needed. Experiments were conducted to determine whether sequential herbicide treatments could be applied in June for control of emerged weeds present in bermudagrass [Cynodon dactylon (L.) Pers.] and prevent further germination of weed seeds during the remainder of the season. Combinations of preemergence and postemergence herbicides were applied in each of 2 years at Griffin or control of large crabgrass and at Atlanta, Georgia for control of goosegrass. Sequential treatments of metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazin-5(4 IH)-one] at 1.1 kg/ha with either benuslide [0,0-diisopropyl phosphorodithioate S-ester with N-(2-mercaptoethyl) benzenesulfonamide], oxadiazon [2-tert-butyl-4-(2,4-dichloro-5-isopropoxyphenyl)-Δ 2-1,3,4-oxadiazolin-5-one], butralin [4-(1,1-dimethylethyl)-N- (1-methylpropyl)-2,6-dinitrobenzenamine], or napropamide [2-(Α-naphthoxy)-N,N-diethylpropionamide] controlled a higher percentage of large crabgrass than when either chemical was applied alone. Single treatments of MSMA (monosodium methanearsonate) or methazole [2-(3,4-dichlorophenyl)-4-methyl-1,2,4-oxadiazolidine-3,5- dione] provide excellent control of large crabgrass. Goosegrass control was greater from sequential treatments of MSMA with oxadiazon, napropamide, or profluralin [N-(cyclopropylmethyl)-Α, Α, Α-trifluoro-2,6-dinitro-N-propyl-p-toluidine] than with MSMA alone. Methazole and metribuzin each controlled goosegrass almost completely." |
