Drought and salinity tolerance of cool-season turfgrasses
… the drought tolerance of thirty-five cool-season turfgrasses, including 15 Kentucky bluegrass lines, 19 tall fescue lines, and 1 perennial ryegrass line were evaluated under three deficit irrigation treatments, 40%, 60% and 80% evapotranspiration (ETo) from 2018 to 2020. Overall turfgrass quality, …

Control of two perennial grasses in southern turfgrasses
Knotgrass (Paspalum distichum L.) and torpedograss (Panicum repens L.) are perennial grasses that are extremely difficult to remove in established turfgrass. Studies were conducted to determine the potential for controlling these troublesome perennial weeds. Pot studies were conducted for two years …

Crop-water stress index models for cool season turfgrasses
Crop Water Stress Index (CWSI) technology has shown potential in improving irrigation timing as it determines timing based on the plant's need. Research was conducted to better apply this technology to turf management. The objectives of this study were (i) to determine the complexity of model …

Evaluation of fine fescues as alternative golf course fairway turfgrasses
In the cool-season region of the United States, golf courses traditionally grow high-input grasses like creeping bentgrass (Agrostis stolonifera, L.), Kentucky bluegrass (Poa pratensis, L.), annual bluegrass (Poa annua, L.), and/or perennial ryegrass (Lolium perenne, L.) on fairways. Grass species …

Influence of seed and foliar applications of growth regulators on turfgrasses
The effects of propiconazole and seaweed extract seed treatments on the germination of Kentucky bluegrass (<i>Poa pratensis L.</i>) under osmotic and temperature stresses were determined in the laboratory. As polyethylene glycol (PEG) 8000 concentrations was increased from 50 to 250 g/L, percent …

Ecology and Taxonomy of Leptosphaerulina spp. Associated with Turfgrasses in the United States
… senectophyte, weak pathogen, and pathogen of turfgrasses. There has also been conflicting reports regarding the delineation of species within the genus Leptosphaerulina. Because of the uncertainty regarding the ecology and taxonomy of the genus in relation to turfgrasses the present study was …

Physiology and Growth Responses of Cool Season Turfgrasses Treated With Trinexapac -Ethyl or Paclobutrazol
… are often routinely applied to highly managed turfgrasses to suppress clipping production, increase sward density, and enhance color. However, reports of variability in the seasonal responses of PGRs indicate further studies are needed to relate environmental factors to PGR efficacy. A series …

Restriction fragment length polymorphism analysis of chloroplast DNA, mitochondrial DNA, and ribosomal DNA in turfgrasses
… samples of 208 cultivars representing the eight turfgrasses was digested with each of four restriction enzymes: Hind III, Bam HI, Eco RI, and Xba I, and probed with a set of ten barley cpDNA clones, nineteen wheat mtDNA clones, and one wheat rDNA clone. The degree, type, and distribution of …

Response of selected warm-season turfgrasses and ornamental monocots to short-term, high concentration, ozone fumigation
Ozone (O3), one of the most powerful oxidants known, is phytotoxic at high levels in the troposphere, or ground-level. Effects of acute ozone exposure for two consecutive days was examined on Bermudagrass (Cynodon dactylon), centipedegrass (Eremochloa ophiuroides), zoysiagrass (Zoysia japonica), …

Cold hardiness studies of bermudagrass and Paspalum vaginatum Sw.
… by dry weight of regrowth obtained from these turfgrasses. Samples of the turfgrasses which were cold stressed in the field were taken into the greenhouse at regular intervals from fall through winter to spring. The degree of injury of samples subjected to low temperature in the laboratory was …

Influence of Isolate, Cultivar, and Heat Stress on Virulence of Rhizoctonia zeae on Tall Fescue
… is a common pathogen of tall fescue and other turfgrasses in various regions of the United States. Disease caused by R. zeae typically occurs during hot, humid summer months when conditions are ideal for growth of the fungus but less than ideal for growth of tall fescue. While R. zeae has been …

Accurate identification and grouping of Rhizoctonia isolates infecting turfgrasses in MD and VA and their sensitivity to selected fungicides in vitro
Rhizoctonia blight (sensu lato) is a common and serious disease of many turfgrass species. The most widespread causal agent R. solani consists of several genetically different anastomosis groups (AGs) and subgroups. Though anastomosis or hyphal fusion reactions have been used to group Rhizoctonia …

Systems to Attract and Feed Pollinators in Warm-Season Lawns
… persistence of herbaceous plants in warm-season turfgrasses such as bermudagrass (Cynodon spp.) and buffalograss (Buchloe dactyloides), may be affected not only by the competitive nature of the turfgrass, but by the cultural practices associated with turfgrass management. While exhibiting …

Nitrogen utilization in creeping bentgrass
… nitrogen utilization efficiency (NUE) of turfgrasses are needed, since nitrate contamination of ground water is a concern on golf courses. In the first study, the conditions of N utilization of fourteen bentgrass cultivars were compared in hydroponic solution culture. There were …
