This research project involved the development and application of crop simulation tools to assist with crop management within the cotton industry.

The aims of the project were: (1) Use composted cotton gin trash and pelletised cotton gin trash to

monitor soil response and soil nutrition benefits; (2) Establish experimental woodlots of

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.

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.

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

ABSTRACT

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.

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.

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.

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, 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.

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.

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.
