While the cotton industry relies on large inputs of Nitrogen fertilizer, most growers are confident that their management of this input is satisfactory.

Strains of cotton aphid and the green peach aphid were collected from cotton producing faints in eastern Australia. Green peach aphid was rarely collected but resistance to Curacron and Pirimor was documented.

Effective resistance monitoring underpins the Australian cotton resistance management strategy for insects and mites.

It is widely recognized that &quote;Plant diseases are a man-made problem&quote;. Our current farming systems are 'pathogen-friendly'.

Concerns about the increase in resistance towards synthetic chemical insecticides in the cotton bollworm, Helicoverpa armigera, led the Australian cotton industry to adopt new pest management ideas.

This topic goes to the heart of the current crisis in the Australian cotton marketing system. The cotton industry is currently in a state of shock.

Judging by the media headlines over the past three years, the dominant issues for sustained use of the Murray-Darling Basin's natural resources are sanity and security of water supply under the Cap on diversio

Interest in Integrated Pest management (IPM) and Area Wide Management (AWM) continues to increase within the Australian Cotton industry.

Water Use Efficiency WUE) means maximising the returns from and minimising the environmental impacts of every megalitre (ML) of water used for irrigation purposes.

Plant diseases are currently threatening the productivity and sustainability of the cotton industry.

A water management approach commonly used by cotton growers in the Condamine - Lower Balonne catchment area is to divide farm storages into several cells.

Black rootrot of cotton has been observed in 98 per cent of the farms regularly surveyed by NSW Agriculture in the Macquarie, Namoi, Gwydir and Macintyre valleys.

Water-use efficiency of cotton production and minimising the impact of the cotton industry on the environment have emerged as issues of great importance.

Cotton is the most important textile crop due to its cellulose-enriched mature fibres, single celled hairs derived from ovule epidermis at anthesis.

In Australia, premature senescence (PS) is occurring with increasing frequency in cotton crops.

The important role that beneficial arthropods play in cotton farming systems is increasingly being recognised across the industry.

Electromagnetic (EM) surveys in combination with computer models, like Sodium-SaLF, and chloride mass balance models have been used to estimate deep drainage under irrigated soils with high clay content (Wills and Bla

Two key hormones, ecdysone and juvenile hormone, control metamorphosis and moulting in insects.

Predatory arthropods are important in cotton IPM programs and planting a diverse range of crops may increase the on farm bio-diversity of predators.

This paper explores some specific short-term impacts of reductions in water available for cotton irrigation. It is noted that longer term impacts are much more difficult to determine.
