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.

Healthy soils are fundamental to the profitability and sustainability of cotton ecosystems.

Limitations on the availability of irrigation water in eastern Australia has created

interest in the possibility of re-establishing cotton in the Oof

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.

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.

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.

Scientific Exchange USA Scientist Dr Tom Sinclair (USDA/University of, Florida) to Narrabri, Following the International Crop Science Congress last year we were presented with a, unique opportunity to host internation

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.

Genetic engineering to confer useful agronomic and fibre traits will lower the cost and time

required for producing improved cotton varieties and will promote environmentally-friendly

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.

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

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

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

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
