Development of a biological control against sugarcane poor root syndrome
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
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 ...
Acquisition of Fiji disease virus by Perkinsiella saccharicida kirk and observations on its instars
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 ...
The effect of sugarcane rust (Puccinia melanocephala) on yield
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.
Inheritance of Fiji disease resistance
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 ...
Development of a fungicide spray schedule to determine the effect of sugarcane rust (Puccinia melanocephala) on yield
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
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
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 ...
Effects of natural enemies on soldier fly (Inopus rubriceps) populations in Queensland
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 ...
Herbicide efficacy screen North Queensland 1986 season
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 ...
