The residual action of nine insecticides commonly used in cotton were assessed on the survival of the native egg parasitoid Trichogramma funiculatum by exposing adult wasps to sprayed cotton leaves 1, 3, 5, 7, 1 O and

During the 1970s and 1980s organophosphates (OPs), particularly monocrotophos (first tested 1969-70, registered 1972-73) and profenofos (first tested 1973-74, registered 1978-79), were the mainstay of mite control for

Resistance to some carbamate insecticides ( methomyl and carbaryl) in H. armigera is has been known since 1983. But at that time no resistance to thiodicarb (also a carbamate) was identified.

A great proportion of the Helicoverpa eggs laid onto cotton never hatch. They are either eaten by predators, dislodged from the plant by wind and rain, killed by climatic extremes, or are infertile.

During the past two seasons, cotton crops growing in Queensland have been surveyed for diseases. In March 1993 specimens of wilted cotton were collected from the Brookstead area of the Darling Downs.

To help coordinate and ensure good collaborative ties between these research groups and to broaden the understanding of soil salinity within the industry, the CRC initiated the development of a Strategic Plan on salin

The aim of this project is to.assess the efficacy of three new classes of hydrolase genes that might have insecticidal activity when introduced into transgenic cotton.

To develop cotton varieties capable of germinating and establishing in cool soils, seed of Siokra S324 was mutated to induce variation. Ii.

This project focused on the control of nutgrass. Nutgrass (Cyperus rotundus) is considered to be the world's worst weed and inf es ts over 15% of the cotton growing area.

The recent pioneering attempts of several cotton growers to produce organic cotton presents an opportunity to monitor pest populations in the absence of synthetic insecticides.

Objectives To continue the development and validation of a series of micro-computer based decision support packages (initially hydroLOGIC and entomoLOGIC) under the generic name CottonLOGIC.,

This project supports the maintenance of fibre testing facilities at the Australian Cotton Research Institute.

A number of laboratory experiments have been run since 1989 to address the area of distribution variation.

I have prepared these notes for our meeting of July 2S.

This project commenced on the 1st July, 1993. Since that time the following has occurred

The work has identified condensed tannin (CT) as occurring in cottonseed hulls but not in cottonseed kernels. Approximately 20% of the CT in cottonseed hulls is extractable and 80% is bound to protein and fibre.

The anisotropic nature of the soil continuum does not lend itself to classification schemes constructed as many are by predetermined hierachical classes.

In order to obtain information of its environmental fate under conditions of use in the Australian cotton industry, this major study was initiated in 1990-91.

The funds requested in the application were for Dr Christian to spend 6 weeks in the laboratory of Dr Art Mcintosh and Dr Carlo lgnoffo in Columbia Missouri, working on aspects of the project "Genetic Engineering
