Assessment of aromatic compounds as strategic lures in a canegrub control program : SRDC final report BS34S
(BSES, 1991)Anethole, n-butyric acid, citral, citronellal, eucalyptus oil, eugenol, geraniol, hexanoic acid, hexan-1-ol, 3-hexen-1-ol, 1-nonanol, pentanoic acid, phenol, sorbic acid and the standard Trece Japanese beetle floral lure ... -
The production and evaluation of gene probes for diagnosis of sugarcane mosaic virus and Fiji disease virus (Final report SRDC Project BS10S)
(BSES, 1991)Specific and sensitive cDNA probes have been developed for detection of both FDV and SCMV in diseased sugarcane plants. Results from glasshouse evaluation indicate that FDV probes are not sensitive enough to be used for ... -
Report by the consultant phytopathologist on the mission to investigate the Fiji disease situation in Madagascar
(BSES, 1991)Presents findings, conclusion and recommendations of the mission to investigate the Fiji disease situation in Madagascar. -
Assessment of the potential of sex pheromones as strategic lures for the control of canegrubs : SRDC final report BS17S
(BSES, 1991)Sex pheromones were shown to be emitted by females of Antitrogus consanguineus, A. parvulus and L. picticollis. Attraction of males of L. picticollis to females of A. consanguineus shows that the compound or compounds ... -
Enhancement potential of 'Ethokem' in control of the common reed (Phragmites australis) using glyphosate
(BSES, 1991)A significant, positive response trend to the addition of the adjuvant Ethokem to Roundup has demonstrated the potential for this additive to enhance herbicidal activity when applied to control the common reed, Phragmites ... -
Population dynamics of Inopus rubriceps in sugarcane fields with emphasis on bionomic factors assisting pest management (Final report SRDC Project BS11S)
(BSES, 1991)Restrictions were placed on the use of dieldrin in 1987 and its registration for use in the sugar industry lapsed in mid-1991. As no other insecticide is presently available to replace dieldrin, there is an urgent need ... -
Pachymetra chaunorhiza as a factor involved in stool tipping in North Queensland : SRDC final report BS33S
(BSES, 1991)The objectives of this project were to determine the soil and environmental factors favouring Pachymetra root rot, and how these contributed to stool tipping in the moderately resistant and susceptible varieties Q117 and Q124. -
Selection of superior crosses of sugarcane : SRDC final report BS6S
(1991)The impact of GxE interaction on the response to three methods of selection was assessed over three locations and three crop-years. The three selection methods considered were two previously used procedures, mass (individual) ... -
Regeneration of sugarcane plants from protoplasts
(1991)This study aimed to develop a protoplast regeneration system for sugarcane so that gene transfer techniques could be applied for cultivar improvement. Published techniques for embryogenic callus culture, cell suspension ... -
Soil constraints to productivity improvement
(1991)Evidence from investigations into fumigation, fungicide application, fallowing and growth of sugarcane on recently cultivated soils strongly suggests that yields in established cane growing areas are being restricted by ... -
Optimum plot shape for variety trials - effect of competition between varieties : Final report 39905083
(1991)Four plot shapes were compared using four replications of 60 clones. The shapes were 4-row long (4L), 4-row short (4S), 2-row long (2L) and 1-row long (1L). The standard length of 9.2m was used for long plots, short plots ... -
An initial evaluation of surge irrigation as a management tool for the Burdekin sugar industry : Final report 89/7
(1991)Conventional furrow and surge irrigation were compared during the growth of second and third ratoon sugarcane crops on a duplex soil in the Lower Burdekin district. Data collection was severely hampered during this ... -
Optimisation of cultural practices for efficient mechanical harvesting : SRDC Final report BS20S
(1991)Some progress has already been made in identifying field conditions and practices which lead to high dirt levels. These include lodged cane, wet field conditions and cutting with the harvester basecutter below ground ... -
Improving the efficiency of nitrogen fertilisation of sugarcane under minimum till and trash conservation cultural conditions (Final report SRDC Project BS37S)
(1992)Objectives of the experiments were (1) Determine the extent of NH3 volatilisation when urea and ammonium sulfate are applied to the surface of a trash blanket in four cane-growing regions. Evaluate the effect of various ... -
Comparison of 'into' and 'beside' stool nitrogen placement
(1992)There are now two alternative methods of subsurface nitrogen placement available: beside the stool or into the stool. The second, into the stool treatment, is easier to accomplish. Comparison of cane yields from strips ... -
Phytotoxic substances associated with the decomposition of sugarcane trash residues. (Final report SRDC Project BS31S)
(1992)Ratooning through trash blankets is generally effective with minor exceptions for certain varieties and in cold or waterlogged soils. Information was required to determine whether these effects are normal reactions of slow ... -
Report on evaluation of nutrient enhancement of biodunder for cane growth
(1992)Three yield trials were conducted to evaluate strategies for the use of biodunder as a fertiliser for sugarcane. Cane growth in the trials was adversely affected by the weather, which was dry in summer, followed by ... -
The effect of harvester settings on cane loss and subsequent ratoon cane yield
(1992)This replicated trial at Tully showed that harvester settings (basecutter height, forward speed, and direction of travel in relation to crop lodging) can significantly influence the amount of cane left in the paddock after ... -
The effect of two different Toft basecutters on ratoon yield
(1992)The visual appearance of the cane stubble remaining after harvesting with the Toft angled underslung basecutter usually fitted to 7000 series harvesters is different to that remaining after harvesting with the horizontal ... -
The contribution of mechanical cane harvesting to the productivity plateau
(1992)The invention of mechanical cane harvesters has been important in the development of the Australian sugar industry. Mechanisation of the harvest has brought many benefits. However associated with mechanical cane harvesting ...
