Buffalograss [ Buchloë dactyloides (Nutt.) Engelm. Syn. Bouteloua dactyloides (Nutt.) Columbus], a dioecious, warm-season grass native to the U.S. plains region, is touted for characteristics like drought tolerance, winterhardiness, and requiring
Buffalograss [ Buchloe dactyloides (Nutt.) Englem.] and blue grama [ Bouteloua gracilis (Willd. ex Kunth) Lag. ex Griffiths] are perennial, warm-season grass species native to the Great Plains. They have high tolerance to drought and heat stresses
). Therefore, exploration of species with increased drought tolerance is advantageous. The present water supply concerns in western Texas and other areas of the arid Southwest have led to the examination of buffalograss as a viable option for managed turfgrass
Buffalograss is a warm-season (C 4 ) perennial grass native to the Great Plains of North America ( Savage, 1934 ; Shearman et al., 2004 ). The stolons of buffalograss branch profusely, creating a dense sod ( Shearman et al., 2004 ; Wenger, 1943
Buffalograss [ Buchloe dactyloides (Nutt.) Engelm.] is a warm-season grass native to the Great Plains of North America ( Wenger, 1943 ), and is commonly established from burs containing three to five caryopses (Beard, 1973; Quinn, 1987 ; Riordan
the first autumn frost and remain dormant until mid to late spring. Some turf managers in the transition zone may avoid the use of warm-season grasses because customers object to the brown color during dormancy. The warm-season grasses buffalograss and
Field studies were conducted at two sites in Nebraska (NE1 and NE2) and one site in Kansas (KS) in 1994 to determine the influence of selected preemergence herbicides on establishment of seeded `Sharp's Improved' buffalograss [Buchloe dactyloides (Nutt.) Engelm.]. Herbicides were applied within 2 days after seeding. Application of imazethapyr at 0.07 kg·ha-1 usually resulted in buffalograss seedling density, vigor, and foliar cover that were superior to buffalograss stands where other herbicides were applied. Buffalograss response to AC 263,222 at 0.07 kg·ha-1 was variable and appeared to be influenced by level of weed interference. Seedling density and vigor of buffalograss on areas treated with AC 263,222 were the same or less than on nontreated areas at KS and NE2, where weed infestations were low and moderate [5% and 45% weed foliar cover 12 weeks after treatment (WAT) on nontreated areas]. In contrast, buffalograss establishment was similar in AC 263,222- and imazethapyr-treated plots at NE1 where the weed infestation was high (>70% weed foliar cover 12 WAT on nontreated areas). At 12 WAT, weed foliar cover was <25 % at NE1 and <1 % at NE2 where imazethapyr and AC 263,222 were applied. Of all herbicides evaluated, imazethapyr at 0.07 kg·ha-1 was superior for suppressing annual grass and broadleaf weeds with no observable deleterious effects on buffalograss establishment from seed. Chemical names used: ±2-[4,5-dihydro-4-methyl-4-(l-methylethyl)-5-oxo-lH-imidazol-2-yl]-5-methyl-pyridine carboxylic acid (AC 263,222); 2-[4,5-dihydro-4-methyl-4-(l-methylethyl)-5-oxo-lH-imidazol-2-yl]-5-ethyl-3-pyridinecarboxylic acid (imazethapyr); 6-chloro-N,N′-diethyl-l,3,5-triazine-2,4-diamine (simazine).
Buffalograss is a warm-season (C 4 ) grass species that originated in Central Mexico ( Quinn and Engel, 1986 ; Quinn et al., 1994 ; Shaw et al., 1987 ; Webb, 1941 ). It is a fine-leaved, stoloniferous perennial grass species grown for turf in the
Buffalograss is native to the Great Plains of North America ( Huff and Wu, 1987 ). This species is widely used as a low-maintenance turfgrass in parks, cemeteries, and rights of way due to its excellent cold, heat, and drought tolerance ( Beard
Buffalograss [Buchloe dactyloides (Nutt.) Engelm.] is a turfgrass species traditionally adapted to low-rainfall areas that may incur unacceptable weed encroachment when grown in higher rainfall areas such as Florida. An experiment was performed to evaluate the tolerance of two new buffalograss cultivars, `Oasis' and `Prairie', to postemergence herbicides commonly used for grass, broadleaf, and sedge weed control. Twenty to 40 days were required for each cultivar to recover from treatment with asulam, MSMA, and sethoxydim (2.24, 2.24, and 0.56 kg-ha-l, respectively). Other herbicides used for postemergence grass weed control (metsulfuron, quinclorac, and diclofop at 0.017, 0.56, and 1.12 kg·ha-1, respectively) did not cause unacceptable buffalograss injury. Herbicides used for postemergence broadleaf weed control, triclopyr, 2,4-D, sulfometuron, dicamba (0.56, 1.12, 0.017, and 0.56 kg·ha-1, respectively), and a three-way combination of 2,4-D + dicamba + mecoprop (1.2 + 0.54 + 0.13 kg·ha-1), caused 20 to 30 days of unacceptable or marginally acceptable turfgrass quality, while 20 days were required for `Prairie' buffalograss to recover from atrazine treatments. `Oasis' buffalograss did not fully recover from 2,4-D or 2,4-D + dicamba + mecoprop through 40 days after treatment. Herbicides used for postemergence sedge control, bentazon and imazaquin, caused slightly reduced, but acceptable, levels of turf quality in both cultivars throughout the experiment. Chemical names used: 6-chloro-N-ethyl-N'-(1-methylethyl)-1,3,5-triazine-2,4-diamine (atrazine); methyl[(4-aminophenyl)sulfonyl]carhamate (asulam); 3-(1-methylethyl)-(1H)-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide (bentazon); 3,6-dichloro-2-methoxybenzoic acid (dicamba); (±)-2-[4-(2,4-dichlorophenoxy)phenoxy]propanoic acid (diclofop); 2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-3-quinolinecarboxylic acid (imazaquin); (±)-2-(4-chloro-2-methylphenoxy)propanoic acid (mecoprop); 2-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino]carbonyl]amino]sulfonyl]benzoic acid (metsulfuron); monosodium salt of methylarsonic acid (MSMA); 2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one(sethoxydim); 2-[[[[(4,6-dimethylethyl-2-pyrimidinyl)amino]carbonyl]amino]sulfonyl]benzoic acid (sulfometuron); [(3,5,6-trichloro-2-pyridinyl)oxy]acetic acid (triclopyr); (2,4-dichlorophenoxyl)acetic acid (2,4-D); 3,7-dichloro-8-quinolinecarboxylic acid (quinclorac).
