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

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

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

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

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

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

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

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®

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

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

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 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.

It is evident from experience with the resistance of H.

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.

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.

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

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, .

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.

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

CRDC's Annual Operating Plan for 2004–06 (AOP): the second annual operating plan under the CRDC's Strategic R&D Plan 2003–2008.

Submerged water plants (aquatic macrophytes) are a desirable component of shallow lakes and wetlands, and management activities should be directed to ensure their continual presence.

Knowledge is one of our most valuable and intangible assets.
