). Research is currently underway to determine the efficacy of mesotrione for broadleaf and grassy weed control in managed turfgrass systems. Mesotrione is not currently labeled for use on actively growing bermudagrass [ Cynodon dactylon (L.) Pers.] turf
evaluate the traffic tolerance of ‘Riviera’ bermudagrass ( Cynodon dactylon L.) after treatment with various PGRs commercially marketed for use in turfgrass management. Materials and Methods Research site. A 2-year field study was conducted
for weed control efficacy in turfgrass and ornamentals ( Armel et al., 2009 ; Brosnan et al., 2010 ). Mesotrione is currently registered for weed control in turf ( Anonymous, 2009b ) and has been shown to injure common bermudagrass [ Cynodon dactylon
% Cynodon dactylon , 50% Festuca arundinacea , and 15% Poa pratensis ). The composted olive stone-amended substrate improved turf visual quality, color, shoot density, uniformity, and coverage. Alburquerque et al. (2007) in a controlled pot study
Leachates of living Cynodon dactylon (L.) Pers. and Amaranthus sp. were applied to Carya illinoinensis (Wangenh.) C. Koch. seedlings to compare effects on growth and elemental absorption. Water applied to the weed pot or control pot (no weeds present) leached through the pot and into a funnel with a tube attached, then directly into the corresponding pecan seedling pot. After 4 months of growth, pecan seedlings receiving weed leachates had less leaf area and were shorter than those watered through control pots. These results suggest that leachates from these two weed species inhibit pecan growth, independent of any competition effects.
In recent years, many improved seeded bermudagrass [ Cynodon dactylon (L.) Pers.] cultivars have become commercially available. As the turfgrass quality of several SB cultivars have reached the level of vegetative industry standards ( Morris, 2002
Abstract
Commercial microorganism inoculum was tested for effectiveness in aiding thatch breakdown in common bermudagrass (Cynodon dactylon (L.) Pers.) turf on two golf courses in Hawaii. None of the materials tested were effective in reducing thatch accumulation over a 5-month test period.
bulbs can persist in zoysiagrass ( Zoysia japonica Steud.) and bermudagrass ( Cynodon dactylon ) in transition zone environments, providing color and biodiversity to dormant turfgrass situations. However, both studies examined a small number of bulb
Abstract
Glyphosate, fluazifop, sethoxydim, haloxyfop, and quizalofop were applied to bermudagrass [Cynodon dactylon (L.) Pers.] and johnsongrass [Sorghum halepense (L.) Pers.] in a ‘Concord’ (Vitis labrusca L.) vineyard in 1985 and 1986. Spray was allowed to contact the grape foliage in all treatments except the glyphosate treatment. Two-year usage of these herbicides controlled johnsongrass and bermudagrass and caused no grape injury. Chemical names used: N-(phosphonomethyl) glycine (glyphosate); (±)-2-[4-[[5-(trifluoromethyl)-2-pyridinyl]oxy]phenoxy]propanoic acid (fluazifop); 2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one (sethoxydim); 2-[4[[3-chloro-5-(trifluoro-methyl)-2-pyridinyl]oxy]phenoxy]propanoic acid (haloxyfop); 2-[4-[(6-chloro-2-quinoxalinyl)oxy]phenyoxy]propanoic acid (quizalofop).
Abstract
Diclofop (2-(4-(2,4-dichlorophenoxy)phenoxy)propanoic acid) caused little to no injury to common bermudagrass [Cynodon dactylon (L.) Pers.] mowed twice weekly at 1.6-2.0 cm at rates of 0.56,1.12, 2.24, and 4.48 kg/ha or to ‘Tifdwarf’ bermadagrass Cyndon dactylon × C. transvaalensis Burtt-Davey, mowed daily at 0.5 cm at rates of 0.56, 1.12, and 2.24 kg/ha. Diclofop at 0.56, 1.12, and 2.24 kg/ha gave good control of mature goosegrass [Eleusine indica (L.) Gaertn.] in ‘TifdwarP turf mowed daily at 0.5 cm, but resulted in inadequate control at 4.48 kg/ha in common bermudagrass turf mowed twice weekly at 1.6 or 2.0 cm.
