Report to the Government of Ceylon on the diseases of sugar cane in Ceylon
(BSES, 1961)Three commercially important diseases of sugar cane were noted during a survey of sugar cane plantings in Ceylon. Several potentially dangerous diseases were seen, while other diseases of minor importance were also present. ... -
A method for the rapid identification of ratoon stunting disease in sugar cane
(BSES, 1977)Work with the electron microscope established a slender coryneform - type bacterium is constantly present in the sap of known ratoon stunting diseased plants and is absent from healthy plants. Purpose of project was to ... -
Inheritance of Fiji disease resistance
(BSES, 1981)Various projects have been conducted in recent years to study the inheritance of resistance to Fiji disease. In this report the results of these studies are presented and the implications for the plant breeding programme ... -
Effects of natural enemies on soldier fly (Inopus rubriceps) populations in Queensland
(BSES, 1983)A study was initiated in 1981 to determine the role of natural enemies of soldier fly in south east Queensland. The objective of this work was to gain an understanding of soldier fly population dynamics in its native ... -
Acquisition of Fiji disease virus by Perkinsiella saccharicida kirk and observations on its instars
(BSES, 1984)The first, second and third instars of Perkinsiella saccharicida were the only stages which transmitted Fiji disease virus to healthy Q70 plants after a 48 hour access feed on diseased plants. A key to distinguish the ... -
Development of a fungicide spray schedule to determine the effect of sugarcane rust (Puccinia melanocephala) on yield
(BSES, 1984)This study reports on work carried out to develop a fungicide spray program which is suitable for yield loss assessment investigations. Aspects examined include the efficacy of various concentrations of chlorothalonil and ... -
The evaluation of rope-wick application of glyphosate as a method of chemical weed control in some typical farm locations
(BSES, 1984)The effectiveness of rope-wick application of glyphosate (as Roundup) in controlling the common reed Phragmites australis in the Moreton and Rocky Point areas has fostered interest in this method of chemical weed control ... -
Studies into races of sugarcane rust
(BSES, 1984)A technique was developed for testing for physiological races of sugarcane rust. A range of cultivars were inoculated with a single spore isolate of Puccinia melanocephala by discharging 3 mg of urediospores into a spore ... -
The effect of sugarcane rust (Puccinia melanocephala) on yield
(BSES, 1985)This report details the results obtained from two trials to assess yeild loss caused by sugarcane rust and also outlines the epiphytotiology of the rust disease. -
Development of a biological control against sugarcane poor root syndrome
(BSES, 1987)The overall objective of the project was to search for and develop an economically effective biocontrol against sugarcane poor root syndrome (PRS). The disease was known to be caused by two pathogenic fungi: Pythium ... -
Bioassay for comparing levels of pythium graminicola in soils
(BSES, 1987)In the study of any soil borne pathogen it is essential to have some technique for determining the level of the pathogen in the soil. The levels of Pythium species in soil have been measured by soil dilution plating on ... -
Herbicide efficacy screen North Queensland 1986 season
(BSES, 1987)In 1984 a wide range of herbicide treatments were evaluated against a number of weed species. Results demonstrated the weakness and strengths of various products, and the optimum timing of application. To further improve ... -
Viability of the seed of itch grass (Rottboellia cochinchinensis) in the Burdekin district
(BSES, 1990)Itch grass, raoul grass, or guinea fowl grass emerged as a problem weed of sugarcane fields in the Burdekin district of North Queensland during the late 1970s - early 1980s. It is considered to be a native of tropical ... -
Varietal control of ratoon stunting disease (RSD) of sugarcane
(BSES, 1990)Ratoon stunting disease, caused by the xylem-limited bacterium Clavibacter xyli subsp. xyli, is prevalent in most sugarcane-producing countries, including Australia. It is regarded as the most damaging disease of sugarcane ... -
Assessment of various food constituents as feeding attractants for canegrubs in a pest control program : SRDC final report BS35S
(BSES, 1991)Cellulose acetate filter disks were used to evaluate sugars, amino acids and ascorbic acid as feeding stimulants for canegrubs. Fourteen sugars, 18 amino acids and ascorbic acid were tested with third instars of Antitrogus ... -
Assessment of aromatic compounds as strategic lures in a canegrub control program : SRDC final report BS34S
(BSES, 1991)Anethole, n-butyric acid, citral, citronellal, eucalyptus oil, eugenol, geraniol, hexanoic acid, hexan-1-ol, 3-hexen-1-ol, 1-nonanol, pentanoic acid, phenol, sorbic acid and the standard Trece Japanese beetle floral lure ... -
The production and evaluation of gene probes for diagnosis of sugarcane mosaic virus and Fiji disease virus (Final report SRDC Project BS10S)
(BSES, 1991)Specific and sensitive cDNA probes have been developed for detection of both FDV and SCMV in diseased sugarcane plants. Results from glasshouse evaluation indicate that FDV probes are not sensitive enough to be used for ... -
