Apart from providing ... -
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 ... -
Chlorotic streak disease in Queensland
Magarey, RC (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 ... -
Chlorotic streak disease of sugarcane : SRDC final report BSS243
Magarey, RC (BSES, 2002)Chlorotic streak is a disease recognised since 1929 and is widespread through the cane growing countries of the world. Despite considerable research, particularly in the 1940-1970 period, the causal agent of the disease ... -
Chlorotic streak resistance screening in the Tully district
Magarey, RC; Sevntek, K; Bull, JI; Stringer, JK; Zamora, R (ASSCT, 2016)CHLOROTIC STREAK DISEASE (CSD) was first recognised more than 85 years ago and is present in most cane-growing countries around the world. An important management strategy is the use of resistant varieties; past research ... -
Chlorotic streak transmission and crop dynamics research
Magarey, RC; Sventek, K; Bull, JI; Braithwaite, KS (ASSCT, 2016)CHLOROTIC STREAK DISEASE (CSD) is transmitted in water, specifically drainage, flood or irrigation water. Research showed that transmission in water was increased by the addition of oxytetracyline (Terramycin). A two-hour ... -
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 ... -
Enhancing resistance to yellow spot disease": SRDC final project report BSS245
Magarey, RC (BSES, 2003)Yellow spot is a leaf disease caused by the fungus Mycovellosiella koepkei. Although known in Queensland since 1950, some facets of the disease have never been adequately researched. Yellow spot principally, but not ... -
Epidemiology studies into sugarcane smut : SRDC final report BSS302
Magarey, RC (BSES, 2010)The objective of this project was to: Optimise industry transition from susceptible to resistant commercial varieties, with minimal losses resulting from direct or in-direct crop effects, thus maximising industry profitability. -
Estimating disease-associated yield losses in breeding selection trials - Endemic diseases; Pachymetra root rot, orange rust and yellow spot
Magarey, RC (BSES, 2007)Previous work has shown that plant improvement stage 3 selection trials can be used to assess the relationship between yield and disease resistance with particular Queensland endemic diseases - principally Pachymetra root ... -
Final report on SRDC project CLW002 (previously CSS02 & CSS2S): The role of root growth and activity in determining sugarcane productivity
Magarey, RC; Nable, R; Reghenzani, J; Smith, J; Berthelsen, S; Grace, D; Robertson, M (1999)When the current project was initiated, poor root growth and activity were widely believed to be a major constraint to sugarcane productivity. However, there was no technology available to assess whether or not root growth ... -
Identification of unknown root pathogens responsible for sugarcane yield decline : SRDC final report BS73S
Magarey, RC (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 ... -
Incidence and economic effects of ratoon stunting disease on the Queensland sugarcane industry : ASSCT peer-reviewed paper
Magarey, RC; McHardie, R; Hession, M; Cripps, G; Burgess, D; Spannagle, B; Sutherland, P; Di Bella, L; Milla, R; Millar, F; Schembri, A; Baxter, D; Hetherington, M; Turner, M; Jakins, A; Quinn, B; Kalkhoran, SS; Gibbs, L; Ngo, C (ASSCT, 2021)Ratoon stunting disease (RSD) has had a significant influence on productivity and profitability in the Australian sugarcane industry for at least the last 76 years. There have been few attempts to objectively quantify ... -
Innovation in disease management; where to next : ASSCT peer-reviewed paper
