In this paper we present data on the effects of N fertilizer application to a wheat rotation crop on soil strength, nutrient uptake by the following cotton crop and cotton lint yields which were obtained from two stud

Properly controlling the cotton ginning process increases fiber yields and monetary returns to the cotton farmer, improves fiber length distribution, and reduces short fibers, neps and seed-coat fragments.

The wild Australian Gossypium species arei subdivided into three sections. Sturtia. Hibiscoidea and Grandicalyx. The first two sections together contain five species.

Creation of lagoons or wetlands. River stabilization techniques. On farm reafforestation. The benefits and disadvantages of these to the landholder and to the environment.

Growing concern in recent years about the effects of pesticides and fungicides on the environment has led to an increased interest in alternative plant protection methods worldwide.

At Tamworth, we have been monitoring H. armigera for carbamate resistance [thiodicarb (Larvin) and methomyl (Lannate, Nudrin) resistance since 1982. Thiodicarb resistance was first diagnosed in H.

Host plant resistance has long been a focus of the CSIRO cotton breeding program with emphasis on both morphological (okra leaf, frego bract) and biochemical factors (high gossypol) for resistance to insects.

Summary Following square and boll loss, damaged plants may became taller and leafier than undamaged plants.

The cotton fields are considered to be a biologically 'sterile' environment because of the constant use of pesticides and herbicides, however little work has been done to document the potential benefit

The Australian cotton industry is at the dawn of a new age in cotton production: an age where most, if not all, of the cultivars in use will carry the products of gene technology.

The CSIRO Cotton Cultivar Trial (CCT has been run cooperativeIy by CSIRO and DPIQ for 22 years and is used as the last stage in our breeding fine evaluation.

The cotton monocultural system in most of the production areas in Australia strongly discriminates against natural enemies and favours the development of pest outbreaks.

The introduction of Bt-transgenic cotton (Ingard) should lead to an overall reduction in insecticide use.

A new project at Narrabri aims to develop methods of breeding cotton varieties that per/ orm better under dryland and limited water situations.

The National Farmers' Federation represents a substantial proportion of Australia's 120,000 farming operations around the country, and those farmers represent just about every sector of the rural indus

Although growers spend much of their time and resources in protecting their cotton crop against attack by insect pests and diseases the plant itself is already well armed against these invaders and your task might be

Fungal diseases, in particular Verticillium wilt, and, more recently, Fusarium wilt, have the potential to cause major losses in Australian cotton production.

Microplitis demolitor (Hymenoptera: Braconidae) is a mid to late season parasitoid of Helicoverpa spp. larvae. Female M. demolitor prefer to lay eggs in second instar larvae.

The computer based decision support system, entomoLOGIC was first developed five years ago as a basic prototype. The first release of the DOS version for commercial use was at the Cotton Conference in 1992.

The disruptive nature of many of the broad spectrum insecticides on which heliothis control relies on cotton limits the adoption of integrated pest management (IPM) programs, particularly where they place emphasis on
