From a humanised viewpoint cotton may be thought of as a lazy plant. It "employs" microscopic fungi to do some of the hard work of collecting nutrients from the soil.

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.

The value of lucerne as a trap crop for cotton pests has been recognised in America for some time (Deloach and Peters 1972, Robinson et al. 1972, Sevacherian and Stern 1974).

Pix is now in common use to manage vegetative growth of cotton in Australia. I presented a paper at the 1992 ACGRA Conference detailing how to evaluate potential responses to Pix.

At the 1992 Australian Cotton Research Conference, we reported on field trials of a prototype Heliothis ID kit that were held during the 1991-92 growing season (Trowell et al., 1992).

HOW IT RELATES TO THE CONCEPT OF BEST PRACTICE, WHAT ARE THE FEATURES OF THE TOP PERFORMERS

After 2 light mite years (1991/92 and 1992193) the cotton industry experienced a season in which outbreaks of mites were widespread.

Two years ago, the computer program entomoLOGIC 1 was first made widely available to cotton growers and consultants.

This is a new project that aims to develop diagnostic molecular probes for the most threatening insecticide resistance mechanisms in Australian H. armigera

Black root rot is caused by the fungus Thielaviopsis basicola (Berk. & Broome) Ferraris.

Compensation is the ability of the plant or crop to offset damage caused by pests or other factors such as hail. Compensation can act at the plant or crop levels.

Insecticide resistance continues to be a major problem for the cotton grower. It also is the focus of much of the research into the use and management of transgenic plants.

Agriculture can change the hydrologic balance of a landscape either through a change from native vegetation or the addition of water by irrigation or both.

Commercial cotton crops throughout NSW have been surveyed in November and March of each season since 1983 to determine disease distribution, incidence and severity.

Nitrification inhibitors were successfully used to improve the recovery of fertilizer N in the irrigated cotton-growing system.

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 the project, to enable cotton to be grown in experiments in the disciplines of breeding, agronomy and entomology by the CSIRO Cotton Research Unit at the Australian Cotton Research Institute, has been met O

To make the OZCOT cotton crop simulation model more robust and versatile; enabling it to be used for decision support in a broader range of applications and situations. This involved five specific objectives: 1.
