The overall aim of the project is to examine the response of cotton to Pix (mepiquat chloride) under different growth rates in the Macquarie Valley.

Agriculture is now recognised to be among the highest risk industry groups for occupational injury and disease.

Various parasitoids of heliothis have been considered in integrated pest management programs throughout the world.

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.

One of the few aspects of our industry that is controllable is injury to people.

Having previously identified poor N recovery as largely a denitrification problem, research began to investigate means of reducing N loss.

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).

In common with about 80% of all plants, cotton forms VAM (vesicular-arbuscular mycorrhizas). VAM are associations of soil-borne fungi with the roots of plants.

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

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

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

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.

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.

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

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

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

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

A research project at the Australian Cotton Research Institute, Narrabri aims at developing biocontrol agents for cotton seedling diseases and Verticillium wilt.

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.
