This review explores some of the more innovative techniques and procedures that can be used to improve regional resource use planning outcomes in rangelands.

In WaterWheel 9 we particularly focus on _educational issues for irrigators.

This project involved a travel grant for the purpose of attendance by CRC and CROCsupported personnel at two international congresses (IUPAC's International Congress on Pesticide Chemistry, London August 2-7, 199

Conventional plant breeding has done much to improve cotton's tolerance to pests and diseases.

The Australian cotton industry has been practising curative conventional insecticide resistance management and preventative Bt transgenic cotton resistance management for fifteen and two years now, respectively.

Determining the level of insect infestation which causes economic damage (yield loss or significant crop maturity delays), is no simple task.

Precision Agriculture (PA) involves the management of sites or regions within a field based on local requirements rather than field average requirements.

Verticillium wilt and Fusarium wilt, vascular diseases caused by the soil-borne fungal pathogens Verticillium dahliae and Fusarium oxysporumf.sp vasinfectum, respectively, are among the most important diseases of cott

Heliothis armigera has been a growing problem for many years, While the cotton producers have borne the brunt of it, reports of increasing damage to crops such as pulses, sorghum an maize have become more frequent.

The long term production of cotton it the same field often leads to low yields, even with 1:large amounts of nitrogen (N) and phosphorus (P) fertiliser.

Microbial damage to raw cotton, sometimes referred to as weathering damage, is a common event in most parts of the world. Microbes, viz. bacteria and fungi, are omnipresent in the environment.

Most crop plants suffer a decline in growth when exposed to saline conditions although cotton is classified as a salt-tolerant crop.

As low densities of heliothis may survive on Bt transgenic plants late in the season, a specific late season control for heliothis is valuable to reduce the survival of individuals resistant to Bt toxin.

In his paper to you, Mike Logan, our youngest Cotton Australia Board Director, said to you, &quote;unless we have the support of the local communities, we are doomed to extinction&quote;.

In cotton, phosphorus (P) is important for early seedling vigour, plant establishment and root development.

Fusarium wilt of cotton (Gossypium. spp. ) is caused by the fungus Fusarium oxysporum schletend f.sp vasinfectum (Atk) Snyder and Hansen (Fov).

Transgenic Bt (Ingard) cotton has been the biggest step achieved so farm reducing insecticide applications to cotton in Australia.

We compared the responses of dryland and irrigated cotton to damage caused by two spotted spider mites in a field experiment at Narrabri. Mites colonies developed at similar rates in irrigated and dryland crops.

The cotton industry is one of the largest user of pesticides among the Australian agricultural sector. It has been estimated that endosulfan and pyrethroids account for 70% of all insecticides.

Many growers show little or no interest in their cotton once it leaves the farm gate.
