Okay, so what should I talk about?

The use of aircraft in agriculture in recent years has provoked much attention.

Again, as for previous conferences, we are providing an update of the ACCT results over the last two seasons. In both seasons 30 entries were tested at each of 12 sites (Warren, Breeza.

I am delighted to have been asked to speak on this vital topic.

The aim of the project was to test the feasibility of using DNA probes to enumerate microorganisms involved in the degradation .of herbicides in soil.

This project was concerned with providing fibre quality data on research, especially breeding, samples. It was run by the Division of Textile Industry at Geelong, Victoria.

This project continued the major study of waterlogging on heavy clay soils after furrow irrigation or heavy rainfall.

Field work was conducted over the 1988/89 and 1989/90 cotton growing seasons in the Central Highlands of Queensland. Pheromone dispensers, specially formulated for P.

The VAX cluster at Myall Vale is an important and essential facility for research and for the use of SIRA TAC by the industry.

The new truck for plant breeding use has been purchased.

This study determined the genetic basis of pyrethroid resistance in Heliothis annigera and characterised those factors that lead to cyclical fluctuations in the frequency of resistance in field populations.

The objective for this project was to field test the basic pest management version of SIRA TAC Plus and to educate SIRATAC Ltd field staff in the use of SIRATAC Plus.

The objective of this project was to provide enhancements to a partially established network of Apple Macintosh microcomputers and central VAX. microcomputers.

To provide adequate access to computing facilities for SIRATAC, Trichogramma and Heliothis Ecology/Modelling projects at the Toowoomba Laboratory

Australian Insecticide resistance mangement Strategy

The project DAN 33L involved studies of insecticide resistance in the major cotton pests Helicoverpa armigera and Helicovera. punctigera.

The use of pyrethroid insecticides on Helicoverpa armigera susceptible crops has been restricted to only 6 weeks each summer since 1983, when resistance to pyrethroids was diagnosed.

Summary of Key Results 1 Most promising techniques for use by advisory staff in the field are penetrometers and root morphological characteristics. 2 Soil smearing may not have significant effects on plant growth.

This project continued the major study of waterlogging on heavy clay soils after furrow irrigation or heavy rainfall.

The number of methods of marketing open to Australian cotton growers has increased in recent years, providing growers with an opportunity to better manage financial risk.
