Chlorotic streak disease in Queensland
(BSES, 1995)Chlorotic streak is a disease of unknown etiology affecting 30-50,000 ha of caneland in Queensland annually. The disease is present in all canegrowing districts but is of greatest incidence in the Herbert River and Rocky ... -
Identification of unknown root pathogens responsible for sugarcane yield decline : SRDC final report BS73S
(BSES, 1996)Sugarcane yield decline (YD) is characterised by poor root development ( a lack of fine root growth, root discolouration) and poor root health. Previous YD research implicated the involvement of unrecognised pathogens in ... -
Economic analysis of RSD control strategies : final report SRDC project BS101S
(BSES, 1995)The aim of this study was to compare the economics of the existing RSD control strategy in Australia of disease-free seed and disinfecting harvesters with breeding cultivars resistant to RSD. Analysis presented in this ... -
Inheritance of resistance to pachymetra root rot : SRDC final report BS27S
(BSES, 1994)Genetical resistance to root pathogens is a sensible strategy for disease control in a perennial crop such as sugarcane. Pachymetra root rot is a serious disease in Queensland and can cause losses of 30-40% in susceptible ... -
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 ... -
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 ... -
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 ... -
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 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 ... -
Enhancement potential of 'Ethokem' in control of the common reed (Phragmites australis) using glyphosate
(BSES, 1991)A significant, positive response trend to the addition of the adjuvant Ethokem to Roundup has demonstrated the potential for this additive to enhance herbicidal activity when applied to control the common reed, Phragmites ... -
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 ... -
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 ... -
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 ... -
Population dynamics of Inopus rubriceps in sugarcane fields with emphasis on bionomic factors assisting pest management (Final report SRDC Project BS11S)
(BSES, 1991)Restrictions were placed on the use of dieldrin in 1987 and its registration for use in the sugar industry lapsed in mid-1991. As no other insecticide is presently available to replace dieldrin, there is an urgent need ... -
Pachymetra chaunorhiza as a factor involved in stool tipping in North Queensland : SRDC final report BS33S
(BSES, 1991)The objectives of this project were to determine the soil and environmental factors favouring Pachymetra root rot, and how these contributed to stool tipping in the moderately resistant and susceptible varieties Q117 and Q124. -
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. -
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 ...
