    Herbicide efficacy screen North Queensland 1986 season
    (BSES, 1987) Williams, RC
    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 the knowledge of currently registered herbicides and of those which may have some potential for use in cane, another series of trials were laid down in 1986.

    Development of a fungicide spray schedule to determine the effect of sugarcane rust (Puccinia melanocephala) on yield
    (BSES, 1984) Taylor, PWJ; Croft, BJ; Ryan, CC
    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 oxycarboxin on rust, the frequency of application of one concentration of chlorothalonil or oxycarboxin on level of infection, and arrangement of spray nozzles to give good coverage of fungicides.

    Development of a biological control against sugarcane poor root syndrome
    (BSES, 1987) Birch, RG
    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 graminicola and an unnamed oomycete causing flaccid root rot. The seriousness of this newly recognised disease, and the dearth of economic controls warranted the effort necessary for such a search.

    The effect of sugarcane rust (Puccinia melanocephala) on yield
    (BSES, 1985) Taylor, PWJ; Croft, BJ; Ryan, CC
    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.

    Studies into races of sugarcane rust
    (BSES, 1984) Taylor, PWJ
    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 settling tower by compressed air at 200 kPa pressure for one second with a settling time of ten minutes. A range of reaction types were obtained using this method. These reaction types were similar to reactions on naturally infected field grown plants. Components of stable resistance such as generation time, uredia number per mm2 and uredia diameter were also evaluated. The more resistant cultivars had fewer uredia per mm2 compared to the susceptible cultivars. No difference was recorded in generation times and size of uredia. The age of the leaf inoculated (between 24 and 75 days) did not have any apparent effect on host reaction type, generation time, uredia number and uredia size.
