    Pest risk analysis of sugarcane for the Northern Australia Quarantine Strategy
    (BSES, 1997) Croft, BJ; Magarey, RC
    The purpose of this pest risk analysis (PRA) is firstly to identify quarantine pests and pathogens which pose a threat to sugarcane, which may enter Australia through its northern borders into the area covered by the AQIS Northern Australia Quarantine Strategy (NAQS); and secondly to, identify measures which could be taken by various agencies to reduce the risks of entry or to minimise the impact of such pests should they arrive. The PRA was conducted as outlined in the FAO Standard "Guidelines for Pest Risk Analysis", and is one of a series of PRAs commissioned by NAQS.

    Technical assessment of survival of smut spores in bales of sugarcane trash
    (BSES, 2008) Croft, BJ
    This assessment considers the survival of smut spores in relation to the proposal to store baled trash until there was a low risk of viable spores being present.

    Smut-proofing the Australian industry - ensuring a reliable cane supply through reduced genetic vulnerability to sugarcane smut
    (BSES, 2009) Croft, BJ; Berding, N
    Since the smut incursion and subsequent spread of the disease breeding for smut resistance has become an essential priority for the BSES-CSIRO Variety Improvement program. The strategy that has been adopted includes the SmutBuster program which aims to maintain advances in breeding for productivity while ensuring that all new varieties have adequate smut resistance.

    Sugarcane smut yield-loss estimates - eastern Australia 2006 : Responses to questions raised by the consultative committee on emergency plant pests
    (BSES, 2006) Croft, BJ; Allsopp, PG; Egan, BT; Hogarth, DM
    This document has been prepared by BSES scientists with extensive experience with sugarcane smut. It is based on our reviews of published literature and first-hand experience with smut in the Ord River Irrigation area and Childers-Bundaberg regions of Australia.

    Screening of Australian germplasm for resistance to sugarcane smut - SRDC final project report BSS214
    (BSES, 2004) Croft, BJ; Berding, N
    Sugarcane smut is a destructive disease that has spread to all commercial sugarcane production areas except Fiji, Papua New Guinea and the east coast of Australia. The disease was recorded for the first time in Australia in July 1998 in the Ord River Irrigation Area (ORIA). The objective of this project was to rate Australian commercial cultivars, advanced selections in the BSES/CSIRO and CSR breeding programs and parental clones for resistance to smut. The ratings will be used to provide smut-resistant cultivars to the ORIA and prepare the east coast industry for a possible incursion.BSES negotiated a contract with the Indonesian Sugar Research Institute (ISRI) to conduct smut resistance screening in Indonesia in 1997 before the incursion in Western Australia. The contract was renegotiated after the incursion to accelerate the testing program. The decision to conduct the testing in Indonesia was made because the quarantine period to move clones to Indonesia was shorter than moving clones to Western Australia. The screening is conducted on Madura Island, which is isolated from commercial cane, and clones can be planted into the smut resistance trials after 1 year in an open quarantine plot. Initially, Indonesia allowed 296 clones that were in the BSES quarantine houses to be screened for resistance with no quarantine period in Indonesia. This allowed BSES to obtain resistance ratings on these clones within 1 year of the incursion of smut into Australia.

    Survey of sugarcane in eastern Australia for sugarcane smut : SRDC final report BSS230
    (BSES, 2000) Croft, BJ; Magarey, RC; Smith, DJ
    Sugarcane smut is a serious disease of sugarcane that can cause yield losses in excess of 30% in susceptible varieties. The disease was found for the first time in Australia on the 21 July 1998 in the Ord River Irrigation Area (ORIA) of Western Australia.An initial rapid survey in eastern Australian sugarcane crops failed to locate smut. Travel by canegrowers to the ORIA and movement of machinery from the ORIA to eastern states prior to the discovery of smut had created opportunities for the disease to enter Queensland and New South Wales. There was also the possibility that the atmospheric conditions that facilitated the incursion into the ORIA, may have carried the disease to the eastern states. The status of sugarcane smut in the eastern states was uncertain at the commencement of the current survey.This report describes the results of a two-year sugarcane smut survey carried out by Cane Protection and Productivity Board (CPPB) and Bureau of Sugar Experiment Stations (BSES) staff in Queensland and New South Wales between the 10 November 1998 and the 17 March 2000.

    Survey of sugarcane in eastern Australia for sugarcane smut : SRDC final report BSS230
    (BSES, 1999) Croft, BJ; Magarey, RC; Smith, DJ
    Objectives of project are to: conduct specific smut surveys to determine whether sugarcane smut is present in eastern Australia. Through publicity campaigns encourage cane farmers to inspect their farms for smut. Collate all survey results and produce reports at least every year or as required. Educate industry in all aspects of smut as a threat to the eastern Australian industry.

    Identification of resistance mechanisms in sugarcane to infection by Pachymetra : SRDC final report BS79S
    (BSES, 1999) McGhie, TK; Maclean, D; Smith, GR; Croft, BJ
    Project objectives- Develop techniques for studying the biochemical reactions of sugarcane to infection by Pachymetra.- Identify biochemical mechanisms of infection by Pachymetra.- Identify biochemical changes produced in sugarcane by infection with Pachymetra.- Compare the effect of chemical constituents of different sugarcane varieties on Pachymetra oospore germination and hyphal growth.- Determine which resistance mechanisms and responses of sugarcane are present in resistant varieties, ranked by glasshouse screening, as an aid to future breeding programs.

    The role of Pythium species in yield decline in Southern cane growing districts : SRDC final report BS80S
    (BSES, 1998) Pegg, G; Croft, BJ; Irwin, JAG
    Yield decline has been demonstrated in all established canegrowing regions of Queensland. Field and glasshouse studies with soil fumigants have shown that yield decline is largely caused by soilborne biological factors. Some evidence suggests that these factors are specific to sugarcane. Yield increases of 30-40% in field experiments with methyl bromide have been obtained in all canegrowing regions. If only 10% of this response could be obtained by partial control of deleterious soilborne microorganisms, returns to the Queensland sugar industry would be increased by more than $30m annually. Pythium species have been responsible for significant yield loss of sugarcane in Louisiana. Limited examinations of soils from the southern canegrowing districts of Queensland has shown that highly pathogenic Pythium species are present. These fungi cause severe damage to cane roots under cold, wet conditions and may be involved in poor ratooning under trash blankets in southern districts. While these fungi may cause large yield losses in central and southern canegrowing regions, their distribution and severity and the need for controls have not been adequately defined. This report briefly outlines the results of a survey of southern Australian canegrowing districts for Pythium species and glasshouse and field experiments to determine the yield losses which can be attributed to Pythium species. Detailed experimental methods and results can be found in the Master's Thesis by G Pegg entitled "The role of Pythium species in yield decline in southern sugarcane growing districts of Australia" which was the result of research conducted in this project.
