Acquisition of Fiji disease virus by Perkinsiella saccharicida kirk and observations on its instars
Croft, BJ; Ryan, CC (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 ... -
Bioassay for comparing levels of pythium graminicola in soils
Croft, BJ (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 ... -
BS172S Pathogen risk analysis to prioritise research and quarantine needs of the Australian Sugar Industry

BS172S Pathogen Risk Analysis to Prioritise Research and Quarantine Needs of the Australian Sugar Industry. A Review of Sugarcane Diseases of Quarantine Risk to the Australian Sugar Industry, 1997
Croft, BJ; Magarey, RC (BSES, 1997)The major diseases of economic importance to sugarcane have been identified and their quarantine risk for Australia has been reviewed. Twelve high to moderate risk quarantinable diseases were identified. Sugarcane smut ... -
Development of a fungicide spray schedule to determine the effect of sugarcane rust (Puccinia melanocephala) on yield
Taylor, PWJ; Croft, BJ; Ryan, CC (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 ... -
Does rotating cultivars with intermediate resistance influence pachymetra root rot of sugarcane : ASSCT peer-reviewed paper
Jensen, AS; Croft, BJ; Parfitt, RC; Brown, PH (ASSCT, 2019)Concerns have been raised by industry members over lower than expected cane yields associated with high oospore levels in sugarcane cultivars rated to have intermediate resistance to pachymetra root rot. This is a significant ... -
Economic analysis of RSD control strategies : final report SRDC project BS101S
Croft, BJ; Page, JR; Bull, JK; Beattie, RN (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 ... -
Effects of pachymetra root rot and nematodes on some elite sugarcane clones in Australia
Bhuiyan, SA; Croft, BJ; Wong, E; Ogden-Brown, J; Turner, M; Parfitt, R; Magarey, RC; Bull, J; Cox, MC (ASSCT, 2016)PACHYMETRA ROOT ROT and nematodes are the two most important soil-borne pathogens of sugarcane in Australia. An experiment was established in Yandaran, Queensland in grey forest soil with high Pachymetra spore counts (>100 ... -
How do current ratings of sugarcane varieties for resistance to smut relate to natural infection
Bhuiyan, SA; Cox, MC; Croft, BJ (ASSCT, 2018)SUGARCANE SMUT, CAUSED by a fungus Sporisorium scitamineum, is an important disease of sugarcane in Australia. Sugarcane smut can be managed effectively through the propagation of resistant varieties. In Sugar Research ... -
Identification of resistance mechanisms in sugarcane to infection by Pachymetra : SRDC final report BS79S
McGhie, TK; Maclean, D; Smith, GR; Croft, BJ (BSES, 1999)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 ... -
Inheritance of resistance to pachymetra root rot : SRDC final report BS27S
Croft, BJ; Berding, N (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 ... -
Pest risk analysis of sugarcane for the Northern Australia Quarantine Strategy
Croft, BJ; Magarey, RC (BSES, 1997)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 ... -
