Abstract Bermudagrasses (species of Cynodon Rich.) are among the most widely used warm‐season turfgrasses in southern and transition zones United States. However, growth quality turfgrass various regions increasingly compromised by insufficient rainfall or inadequate irrigation. Therefore, identifying drought‐resistant cultivars is crucial for maintaining sustainable landscapes conserving water resources amidst increasing frequency drought events. The objective this study was to determine...

Managing turfgrass in arid and semiarid areas of the southern United States is becoming increasingly challenging due to prolonged drought diminishing water resources. Turfgrass managers have been seeking products that control pests while promoting resistance. Civitas TM Turf Defense a new petroleum-derived spray oil (PDSO) mixed with green pigment. Like other traditional PDSO products, reported positive effects on pest management. However, limited information available regarding its impact...

Abstract Common bermudagrass [ Cynodon dactylon (L.) Pers.] is an important turfgrass in tropical, subtropical, and warm temperate climates worldwide. However, molecular information associated with adaptive morphological traits this species limited. Accordingly, the objectives of study were to identify genomic regions establishment rate, spring green‐up, drought response, leaf length width, stem internode width. We used existing high‐density linkage map constructed 3322 single nucleotide...

African bermudagrass ( Cynodon transvaalensis Burtt Davy) is a fine-texture warm-season grass that often crosses with common [ C. dactylon (L.) Pers] to create turf-type hybrid bermudagrass. can adapt colder climates than its origin in the southwestern Transvaal South Africa, which has been used improve winter hardiness of interspecific cultivars. However, underlying genomic mechanisms respond cold temperatures are not fully elucidated species. Accordingly, objective this study was identify...

Abstract Sedges ( Carex spp.) are herbaceous perennials with more than 2100 species recognized, offering significant potential for use in mowed turf, landscape gardens, and ecosystem restoration. Breeding development of improved cultivars within various could have a broad impact across these industries. The lack information on genetic diversity variation most relevant has limited cultivar development. objective this study was to estimate the diversity, population structure, variability...

Bermudagrass ( Cynodon sp.) is a highly productive, warm-season, perennial grass that has been grown in the United States for turfgrass, forage, pasture, rangeland, and roadside use. At same time, many bermudagrass production reclamation sites across are affected by soil salinity issues. Therefore, identifying with improved tolerance important successfully producing reclaiming salt-affected saline irrigated water. In this project, relative of seven clonal-type was determined, including...

Abstract ‘DALZ 1701’ (Reg no. CV‐292, PI 702798) is a third‐generation hybrid resulting from mating interspecific ‘TAES 5723‐47’ with Zoysia japonica (Steud.) ‘ Meyer’. In the 2019 National Evaluation Turfgrass Program, which ran to 2022 in 15 locations, DALZ 1701 was put test. 9 of 13 established more quickly than Meyer, similarly Emerald and Zeon but slower Empire. 1701's turfgrass quality generally better Meyer's on par that Emerald, Empire, Zeon. Compared displays dark green genetic...

Turfgrass managers are using reclaimed water as an irrigation resource because of the decreasing availability and increasing cost fresh water. Much attention, thereby, has been drawn to select salinity-tolerant turfgrass cultivars. An experiment was conducted evaluate relative salinity tolerance 10 common bermudagrasses ( Cynodon dactylon ) under a controlled environment in randomized complete block design with six replications. ‘SeaStar’ seashore paspalum Paspalum vaginatum included this...

Fine‐textured, high‐quality zoysiagrasses ( Zoysia spp.) lack freezing tolerance for use in much of the transition zone United States. Two fine‐textured interspecific zoysiagrass hybrids, KSUZ 0802 [ Z. matrella (L.) Merr. × japonica Steud.] and 1201 pacifica (Goudswaard) M. Hotta & Kuroki ] were evaluated field winter survival Manhattan, KS, along with standards ‘Meyer’ ), ‘Empire’ ‘Zeon’ ). Grasses established from vegetative plugs June 2013 injury quality 2014 to 2016. The low...

Abstract A 10‐yr, four‐phase collaborative effort among three universities was conducted to develop new hybrid zoysiagrasses ( Zoysia spp. Willd.) with improved turf quality, winter hardiness, and pest resistance in comparison commercial zoysiagrass cultivars, especially ‘Meyer’ Z . japonica Steud.). In Phase 1, breeding efforts produced 2,858 progeny that were evaluated for 2 yr across sites. 2, only 60 (2%) of selected advancement 10 replicated multiyear field trials (Phase 3). 3 revealed...

Traffic injury caused by foot- or athlete-surface interaction is one of the most critical problems athletic field managers face in maintaining surface playability and aesthetic quality fields. Bermudagrass ( Cynodon spp.) widely used turfgrass species on fields transitional climatic zone. A 2-year study was conducted to evaluate nine bermudagrass cultivars for their persistence under simulated fall cleat traffic. The experiment Stillwater, OK, a natural loam soil. Treatments were arranged as...

Abstract Bermudagrass ( Cynodon spp. Rich) is a warm‐season grass that widely planted throughout tropical, sub‐tropical, and even temperate climates, it generally requires fewer inputs than most cool‐season turfgrasses. In recent years, the area of adaptation for bermudagrass has progressively expanded to cooler climates due development more cold‐tolerant cultivars. The as well reduced required maintain healthy turfgrass have made popular choice in areas marginal adaptation. these areas,...

Abstract Irrigation management of turfgrass under reduced irradiance can be complicated by interactions between evaporative demand, shade tolerance, and competition for soil water from tree roots. A greenhouse study was conducted to understand how influences the drought resistance three turfgrasses. The turfgrasses used in this were Falcon IV tall fescue [ Schedonorus arundinaceus (Schreb.) Dumort., nom. cons.], OKC1119 (Latitude 36 ® ) hybrid bermudagrass Cynodon dactylon (L.) Pers. ×...

Core Ideas A polystand mixture of tall fescue and zoysiagrass showed reduced brown patch disease severity compared to a monostand. Mixing with improved turfgrass quality during summer months when was active. In systems, creating polystands comparable color texture may be feasible strategy for reducing disease. Tall (Schedonorus arundinaceus Schreb.) is used frequently in Kansas due its heat drought tolerance other cool-season grasses. Brown caused by the fungus Rhizoctonia solani Kühn AG-2–2...

There is a growing trend of cultivating hybrid bermudagrass [ Cynodon dactylon (L.) Pers. × transvaalensis Burtt-Davy] on golf course putting greens in the transition zone because its excellent quality summer months, coupled with less pesticide input than creeping bentgrass ( Agrostis stolonifera L.). However, long-term success hindered by low temperatures winter particularly zone. To address this issue, addition to genetic improvement for cold hardiness through development new cultivars,...

These progeny were evaluated for hardiness agronomic traits (establishment rate, overall quality, spring greenup, leaf texture, genetic color) Manhattan, KS; West Lafayette, IN; Dallas, TX; from 2012 2014. From this work, 60 identified further evaluation larger plots. During the 2015-2016...

Seeding zoysiagrass at 1 lb PLS/1,000 sq ft in June with subsequent seeding of tall fescue into established September 8 lbs resulted the best mixture these two species.

Earlier research has demonstrated that polystands of zoysiagrass and tall fescue can be established successfully, with the potential to provide a high-quality turfgrass stand reduced inputs. Our objective was determine whether mixing will reduce brown patch severity while maintaining overall acceptable quality. Studies were at Rocky Ford Turfgrass Research Center in Manhattan, KS. In split-plot design, natural infection by Rhizoctonia solani or fungicide-treated control whole-plot treatment...
