| Abstract/Contents: | "Goosegrass [Eleusine indieca (L.) Gaertn.] control is a major problem weed in bermudagrass [Cynodon dactylon (L.) Pers.] putting greens and it is usually necessary to apply postemergence herbicide treatments throughout summer and early fall for effective control. Since bermudagrass greens are overseeded with cool-season grasses in early fall, a study was conducted on a Cecil (Typic Hapludult) sandy loam at Experiment, Ga. to determine the interval needed between herbicide treatments and time of overseeding without injuring the newly planted turf. A 'Tifway' bermudagrass putting green was treated with MSMA (monosodium methanearsonate), methazole [2-(3,4-dichlorophenyl)-4-methyl-l,2,4-oxadiazolidine-3,5-di -one], metribuzin [4-amino-6-tert-butyl-3-(methylthio)-astriazin- 5(4H)-one] and combinations of MSMA with either methazole or methribuzin at 0, 1, 2, 4, and 6 weeks before overseeding with perennial ryegrass (Lolium perenne L. 'Medalist IV' and 'Medalist V'). Methazole applied alone was the only herbicide that required at least 1 week between treatment and overseeding without affecting the stand of newly planted turf. Metribuzin applied on day of overseeding significantly reduced seedling vigor but not turf stand. Combinations of MSMA with either methazole or metribuzin did not affect growth of ryegrass when applied anytime up to the day of overseeding." |
