The major challenge to sustainable use of Bt cotton is the risk that the target pests, Helicoverpa spp, may evolve resistance to the engineered toxins.

Host Plant Resistance of Cotton genotypes. Australian cotton is attacked by a diversity of insect pests.

The silverleaf whitefly is characterised by a huge host range, high fecundity, the ability to induce physiological responses in plants, transmit plant viruses, the copious production of honeydew, and an extreme abilit

The expansion of the insectary facilities will enable the reseach infrastructure capacity of ACRI to meet the increasing demands of the Industry for entomology research.

Project objectives, The four objectives of this project were; * To characterise the soil types of the lower Lachlan River Valley used for cotton, production.

Pesticides provide essential protection in the production of many agricultural commodities.

Screening of native whitefly from host specificity testing list continues with the following results of host testing of Eretmocerus hayati.

The following whitefly species have been tested:

The availability of accurate and continuous weather and climate data is essential for strategic research, operation of decision support systems (eg.

To help understand the underlying basis of the resistance to pirimicarb, and hence improve the chance of effective management, Dr Robin Gunning and Dr Graham Moores (Rothamstead, UK) did a preliminary screen on resist

Since1988, CRDC has funded a series of projects focussing on the management of problem weeds (nutgrass, polymeria takcall, cowvine, budda pea, lippia and others) and weed management systems for the cotton industry.

An automatic flow analyser was purchased to analyse nitrate, phosphate, chloride and sulfate. The monies for the instrument were a combination of CRDC, Australian Cotton CRC and University of Sydney funding.

Key factors in managing transgenic Bt cottons for the future are to have an effective resistance management strategy. An essential component of any such strategy is to establish a resistance monitoring program.

The commonly used Micronaire value for cotton is related to both fibre fineness and maturity. There is a need for a new measurement technique to separate these.

'Biodiversity' refers to the diversity of genes, species, ecosystems and ecoregions. Like other

sectors in the Australian economy, the cotton industry has a duty of care to ensure its

The aim of this report is to provide a picture of how IPM is working on the ground, by giving an understanding of the thoughts of cotton growers and consultants in relation to IPM.

A series of trials for evaluating new cotton strains and cultivars in Queensland was conducted in collaboration with the CSIRO cotton breeding programs based at Narrabri.

Cotton fibre maturity is an extremely important property to spinners and fabric manufacturers because it determines how well fibres will process both from a chemical and a physical perspective.

Resistance is an ongoing concern with the management of H.armigera in the Australian

cotton industry. Management strategies are in place to either prevent, or retard, further

The Industry Development Officer (IDO) of Moree (Julie O'Halloran) is part of the, Australian Cotton National Extension Team.

Fov is the causal organism of Fusarium wilt disease in cotton. This disease is of serious concern to the cotton industry in terms of potential yield loss.
