A small coryneform bacterium was consistently isolated from sugarcane with ratoon stunting disease and shown to be the causal agent. A similar bacterium was isolated from Bermuda grass. Both strains multiplied in sugarcane and Bermuda grass, but the Bermuda grass strain did not incite the symptoms of ratoon stunting disease in sugarcane. Shoot growth in Bermuda grass was retarded by both strains.

Growth, cecal volatile fatty acids, mineral profile of plasma, liver weight and gastrointestinal weights were measured in rabbits fed isonitrogenous, equicaloric diets containing 3, 6, 9 or 12% dietary crude fiber from either alfalfa or Coastal Bermuda grass. Rabbits were fed from 4 to 8 wk of age. Alfalfa diets improved (P less than .05) average daily gain (20.5 vs 11.9 g/d) and livability (67...

turfgrasses are usually important groundcover plants in many landscapes. they occupy the lowest surface of the landscape, close to pollutant particles. so, they can be an attractive option for environmental remediation. today, high concentrations of hazardous chemicals such as lead are among the most serious environmental problems. in vitro selection of turfgrass accumulator or tolerant of toxi...

BACKGROUND Grass pollen allergens are a major cause of allergic respiratory disease but traditionally prescribing practice for grass pollen allergen-specific immunotherapy has favoured pollen extracts of temperate grasses. Here we aim to compare allergy to subtropical and temperate grass pollens in patients with allergic rhinitis from a subtropical region of Australia. METHODS Sensitization t...

Exudates produced from Bermuda grass roots were collected in deionized water from sterilized Bermuda grass sod at 3-day intervals over a period of 15 days. Exudates were analyzed for total organic carbon, and characterized via Fourier Transform Infrared Spectroscopy. Exudate samples were adjusted to pH values of 4.5, 6.5, and 7.5, amended with lead and quantified for soluble and complexed lead ...

OBJECTIVE To assess the contribution of ground variables including grass type to the rate of anterior cruciate ligament (ACL) injury in the Australian Football League (AFL), specifically which factors are primarily responsible for previously observed warm season and early season biases for ACL injuries. METHODS Grass types used at the major AFL venues from 1992 to 2004 were established by con...

BACKGROUND Pollens are important triggers for allergic asthma and seasonal rhinitis, and proteases released by major allergenic pollens can injure airway epithelial cells in vitro. Disruption of mucosal epithelial integrity by proteases released by inhaled pollens could promote allergic sensitisation. METHODS Pollen diffusates from Kentucky blue grass (Poa pratensis), rye grass (Lolium perenn...

Predatory potential and performance of the predaceous heteropterans, Geocoris punctipes (Say), G. uliginosus (Say) (Geocoridae), and Orius insidiosus (Say) (Anthocoridae), were evaluated using fall armyworm, Spodoptera frugiperda (J. E. Smith), as prey on different turfgrass taxa (resistant zoysiagrasses, 'Cavalier' and 'Palisades'; moderately resistant Bermuda grass, 'TifSport'; and susceptibl...

A phytoplasma was detected in golden beard grass (Chrysopogon acicalatus) displaying white leaf symptoms near vegetative fields at the Tatkone region in Myanmar, 2011. Based on restriction fragment length polymorphism analysis of PCR-amplified 16S rRNA genes, including the 16S-23S spacer region and part of the 23S rRNA gene, the phytoplasma was identified as a member of the Bermuda grass white ...

The Anthelmintic activities of different extracts of aerial parts of Cynodon dactylon Pers were evaluated separately on adult Indian earthworm (Pheritima posthuma). It was found that petroleum ether (PECD), chloroform (CECD), ethanol (EECD), aqueous extract (AECD) of C. dactylon showed anthelmintic activities at the concentration of 5 mg/ml of each. The anthelmintic effects of PECD, CECD, EECD ...
