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.

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

and consequences of climate variability and climate change.

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, .

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.

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

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

The emergence of multiple resistance to insecticides in Helicoverpa populations has had a significant impact on the production of most major field crops in Australia.

Trichogramma limit pest damage to Ord River Irrigation Area (ORIA) cotton crops by killing the developing embryo of their insect host at the egg stage, effectively reducing the number of emergent pests ingesting trans

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

The research into aphid bio-control in cotton has documented the agents attacking cotton aphid in southern and central Queensland, and provided an indication of their relative importance.

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

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

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.
