This research project involved the development and application of crop simulation tools to assist with crop management within the cotton industry.

The aims of the project were: (1) Use composted cotton gin trash and pelletised cotton gin trash to

monitor soil response and soil nutrition benefits; (2) Establish experimental woodlots of

This project aimed to identify factors that could substantially influence Bt efficacy in, transgenic cotton. Cry1Ac protein concentration in cotton leaves was measured quantitatively, using a commercial ELISA assay.

Five sites representing the main cotton growing soil types in the Lower Macquarie Valley were selected and soil sampled in late October and May 2004.

The research project described in this report is concerned with the isolation and, characterization of a gene/enzyme system for the bioremediation of endosulfan sulfate, (endosulfate), the toxic metabolite of endosulf

Cotton production in Central Queensland will continue to impose a unique set of challenges due to climate and it’s remoteness from other production areas.

Fusarium wilt is considered by many growers, ginners, consultants and other industry personnel as the most important constraint to sustainable cotton production to have developed in recent years.

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.

Since the first reported control failures at Emerald during the 1998-99 cotton season, insecticide resistance in cotton aphid, has emerged as a significant threat to the Australian cotton industry.

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.

The project has made significant contributions to further our understanding of causes

and consequences of climate variability and climate change.

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).

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

Purpose of Exchange: Attend Visual Basic Developers Conference, This application was for Scott Johnston to attend the Access/ Visual Basic Developers, Conference, Las Vegas, Nevada USA, 8-12 June 2003.

Fusarium wilt, caused by Fusarium oxysporum f. sp. vasinfectum (Fov), is a destructive disease of cotton (Gossypium hirsutum L) in almost all cotton producing countries of the world.

This project was designed to assess the potential of a plant derived antifungal gene (NaD1) for control of cotton pathogens. The NaD1 gene codes for a small protein called a plant defensin.

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
