With the exception of the undesirable characteristic of summer dormancy and the accompanying low aesthetic value, crested wheatgrass has many desirable characteristics in semiarid environments, making it a promising candidate for lower water use turf. Using a population of 27 half-sib families, this study characterized the underlying genetics of turf quality (based on a 1–9 rating scale) of cre...

A long green period is essential for a turfgrass species with high ornamental value and a wide area of use. Zoysiagrasses (Zoysia spp. Willd.) are perennial turfgrass species popular in tropical, subtropical and temperate zones, possessing many properties necessary to be economically useful turfgrass. They do not have a long green period because of cold sensitivity. A main focus in zoysiagrass ...

D r. George Wallace a researcher from UCLA, writing in HortScience called the 1980s the decade for advancement in our knowledge of iron (Fe) and plant nutrition. He states: "More progress was perhaps made in the 1980s on understanding and management of Fe chlorosis in plants than during the previous 150 years since it became known that Fe deficiency was involved in the chlorosis." Iron is used ...

Since bentgrass greens in desert golf courses are vulnerable to injury from black turfgrass ataenius (BTA) beetles (Ataenius spretulus), UCR entomologists have determined when damaging populations are likely to be present and have identified an economic injury level superintendents can use to implement control measures. “The threshold levels for damaging populations of BTA on bentgrass in the l...

Bermudagrass is often overseeded with a cool-season grass species in the fall to provide a green surface during cool weather. Recently, two new turfgrass species, meadow fescue and tetraploid ryegrass, have shown promise for use in overseeding situations. The objective of this study was to determine the performance of herbicides commonly used to remove (transition) perennial ryegrass from an ov...

Golf course putting greens may be affected by various turfgrass pests. Fungicide applications are often necessary on either a preventive or curative basis and may target more than one disease. The initial objective of this trial was to assess the ability of various fungicides to provide curative suppression of Type II fairy ring symptoms on a creeping bentgrass (Agrostis stolonifera) putting gr...

Abstract The ascomycete fungus Microdochium nivale is one of the most damaging pathogens cool season turfgrass. Prevention and recovery from infection costly to many sports facilities each year. In recent years, use chemical plant protectants has been restricted turfgrass managers have increasingly sought alternative measures for disease control. phosphite shown be effective in reducing M. symp...

do not completely contact the soil. Furthermore, it is possible that the adsorption of ions by resins is governed by Anion exchange membranes (AEMs) are a potential method for two distinct diffusion coefficients, an internal and an exdetermining the plant available N status of soils; however, their capacity for use with turfgrass has not been researched extensively. The ternal coefficient (Coop...

Abstract High quality turfgrass requires adequate amounts of nitrogen (N) fertilizer. However, excess N application can increase losses via leaching and gaseous emissions. Enhanced efficiency fertilizers (EEF) humic substances have been used to decrease the environment. A two‐year field experiment was conducted on a native soil with Kentucky bluegrass ( Poa pratensis L.) investigate if addition...
