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

The Australian cotton industry is heavily dependent on chemical insecticides for pest control.

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.

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®

It is evident from experience with the resistance of H.

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

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

Regular disease surveys have highlighted the changing status of cotton diseases over time and

provided valuable insights into the factors affecting their distribution and severity.

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

Cotton Bunchy Top is a disease of cotton that was first reported in the 1998-99 cotton season. Symptoms of the disease include shortening of internodes and petioles, .

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

This report aims to review the literature, particularly past and current cotton-funded research,, to:, 1. describe biodiversity and the role of biodiversity in cotton production systems;, 2.

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

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

List the project objectives and the extent to which these have been achieved., ?

Final Report as participant in the 2004 Australian Rural Leadership Program

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.

Taking advantage of a GRDC funded trip to attend the Annual meetings of Soil Science SOC of America held in Indianapolis, I requested CRDC funds to visit laboratories involved in research related to Bt-crops and soil

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

2. List the project objectives and the extent to which these have been achieved., 1. Monitor the diversity and distribution of strains of Fov in cotton growing areas in Australia.

The talks presented at the Beltwide cotton conference which will have the greatest impact on researchers, and the Australian cotton industry as a whole, will be the new transgenic insecticidal packages of MXB-13 from

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.
