Helicoverpa spp. are arguably Australia’s most important insect pests, costing the

economy $200-300M annually. Significant advances in the management of

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

Temperature plays a critical and complicated role in the growth and development of 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.

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.

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

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

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

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.

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.

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

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 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.

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).

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
