Thatch is a layer of living and dead plant material (stems roots) between turfgrass leaf tissue the soil surface. If excessive, thatch can decrease turf playability, increase scalping disease pressure, reduce pesticide efficacy water infiltration, harbor insects. In golf putting greens, disruptive mechanical practices such as vertical mowing, core cultivation, grooming, topdressing are traditio...

Anthracnose (caused by Colletotrichum cereale) is a destructive fungal disease of weakened turf that occurs throughout the U.S., Canada and Western Europe (15) and is particularly severe on annual bluegrass (Poa annua). The frequency and severity of anthracnose epiphytotics on golf course greens has increased over the past decade (13,14) and is thought to be associated with some of the manageme...

Multiple playing surfaces and footwear used in American football warrant a better understanding of relationship between different combinations of turf and footwear. The purpose of this study was to examine effects of shoe and stud types on ground reaction force (GRF) and ankle and knee kinematics of a 180° cut and a single-leg 90° land-cut on synthetic turf. Fourteen recreational football playe...

abstract turf grass as a main grown cover plant has a unique place in green space planning. in order to study the effect of hydrogel and paclobutrazol on water requirement of turfgrasse (lolium perenne l. barbal) a factorial experiment based on a brcd with 3 replication was conducted in the summer of 2010 in mashhad. the factors under study were 4 levels of hydrogel (0, 3, 6, 9 gr/kg soil), 3 l...

The demand for salinity-tolerant turfgrasses is increasing due to augmented use of effluent or low-quality water (sea water) for turf irrigation and the growing turfgrass industry in coastal areas. Experimental plants, grown in plastic pots filled with a mixture of river sand and KOSAS(R) peat (9 : 1), were irrigated with sea water at different dilutions imparting salinity levels of 0, 8, 16, 2...

Humic substances are routinely applied to creeping bentgrass putting greens during times of stress to improve turf health. Confounding effects of added nutrients and other ingredients make it difficult to separate the effects caused by the organic material from additional effects of the supplemental ingredients. Claims made in advertising and marketing of the effectiveness of humic substance pr...

An essential component of an introductory turfgrass management course is the description of how turfgrass species are adapted to different cultural systems and environments. The objectives of this project were to develop an interactive program to introduce the characteristics of turfgrass species and their optimum environments and to evaluate the students' gain in understanding turf species cha...

Course Managers and greenkeepers are well aware of the deleterious aspects of excess thatch: Increased disease and insect problems, localised dry spots, chlorosis of the turf, proneness to scalping, foot printing, decreased heat, cold and drought hardiness, restricted rooting, nitrogen immobilization, reduced effectiveness of pesticides, a soft, spongy surface in wet weather, and the potential ...

Improvement in stress tolerance of forage and turf grasses is a major breeding goal. Most forage and some turf grasses are grown on marginal lands under stressful environments with minimal inputs. In contrast, current high-input turf grass production systems such as golf courses and lawns are expensive and often environmentally unfriendly. Cultivars with improved stress tolerance are necessary ...
