The current project was devised in the knowledge that increased sodicity and salinity of percolating water will alter the saturated conductivity of many soils, especially sodic soils.

This project investigated how key insect predators contribute to the suppression of the cotton bollworm, Helicoverpa armigera, in Australian cotton crops and explored the interaction between predator abundance and div

Salinisation as a consequence of irrigation can occur as a result of the application of poor quality (i.e. saline) water or mobilisation of salts from rising water tables (i.e.

Fusarium wilt, caused by Fusarium oxysporum f. sp. vasinfectum (Fov), is a serious disease

of cotton in Australia responsible for substantial yield reductions. Since its detection on the

Soil biota communities are one of the most diverse groups of earth’s biota.

Australian irrigated cotton growers are committed to improving their Water Use Efficiency (WUE) for economic, environmental, social and political reasons (Breen et al, 2006).

Fusarium wilt disease has the potential to cause significant yield losses and the removal of some areas from cotton production. It is therefore likely to impact on the long-term sustainability of the cotton industry.

Centre Pivot and Lateral Move (CF&LM) irrigation machines are gaining popularity within

the Australian cotton industry, as they can provide high application efficiency and

Cotton aphid (Aphis gossypii Glover) is a late season pest of cotton, with the potential to

reduce the value of lint by contaminating it with sticky honeydew secretions. Recently, cotton

To establish if the spider communities in cotton at different locations around Australia are similar, we sampled, using beatsheets and pitfall traps, over 4500 spiders from seven locations extending from the tropical

The significance of transgenic cotton in the pest control strategy adopted by the

Australian industry makes the management of resistance to the Cry1Ac toxin of Bacillus

In growing their crops Australian cotton farmers need to comply with Australian regulations.

Cotton fibres are the fastest growing and among the longest single cells in the plant kingdom. In the space of about16 days, these single cells can expand from a few micrometers to 3 cm in length.

Aims, * To co-ordinate the adoption of research into sound management, practices in the Gwydir Valley cotton-growing region., The position has contributed to this general aim through most extension, activities which a

This project examined how and when individual Helicoverpa armigera carrying a resistant allele (BX) were favoured in field-grown cotton, particularly on Ingard®.

The emergence of multiple resistance to insecticides in Helicoverpa populations has had a significant impact on the production of most major field crops in Australia.

Shielded sprayers have been widely and quickly adopted by cotton growers for weed control

in the inter-row. In the last three seasons, the increase in area sown to RoundUp Ready®

Trichogramma limit pest damage to Ord River Irrigation Area (ORIA) cotton crops by killing the developing embryo of their insect host at the egg stage, effectively reducing the number of emergent pests ingesting trans

It is evident from experience with the resistance of H.

The research into aphid bio-control in cotton has documented the agents attacking cotton aphid in southern and central Queensland, and provided an indication of their relative importance.
