The objective of this study is to examine the scope for further research irito certain quality characteristics of Australian cotton which are seen by many cotton industry participants as critical areas for improvement if the Australian fibre. is to maintain its reputation for excellence, namely: * neppiness * short fibre conten

Aims * To evaluate treatments that inhibit or restrict microbial degradation to cotton when the seed cotton harvest is delayed by wet weather. * To ensure that such treatments do not affect subsequent processing and dye uptake. * To develop dyeing formulations that minimize the effects that microbial damage has on the dyeing of cotton blends.

This document is designed to assist users to develop a spray and drift management plan for their own farming operation, and applies equally to aerial and ground applications. The development of a spray and drift management plan is based on two fundamental requirements:

Aim: To build a new glasshouse to provide a facility for basic research into plant I herbivore interactions

The handbook is divided into two parts and nine sections. It is anticipated that growers will want to refer more frequently to sections on ground spraying technology, safety, handling and application. This material has been compiled together in the front of the handbook as Part A. In Part B, sections on meteorology, nozzle technology and the use of agricultural aircraft in cotton production are provided which discuss relevant background material in more detail.

This report is based on data gathered with the assistance of the membership of Cotton Consultants Australia Inc. (CCA) and covers all major cotton growing regions in Australia. The data analysed are drawn from a sample of 110 paired comparisons oflngard and conventional cotton crops. The sample draws on data from 7,634 ha of Ingard cotton, which represents approximately 9% of the 85,000 ha of transgenic cotton grown in 1998/99.

The Cotton Research and Development Corporation (CRDC) asked the University of Queensland to undertake a study to indicate socio-economic areas for research for the cotton industry. This report presents the issues that are concerning the cotton industry and recommendations for Cotton Research and Development Corporation (CRDC) from the study, which was conducted in the second semester in 1999.

The current, first edition of the Best Management Practices Manual was developed as part of the joint research program"Minimising the Impacts of Pesticides on the Riverine Environment'', which was funded by the Cotton Research & Development Corporation, the Land & Water Resources Research & Development Corporation and the Murray-Darling Basin Commission. The continued development and implementation of the Manual is being overseen by an industry "BMP Management Group", which has representatives from the Australian Cotton Growers Research Association, CRDC, the CRC and Cotton Australia. The current edition focuses on pesticides management, with sections on farm design and management, pesticide storage and handling, application of pesticides and integrated pest management.

The focus of this project included several aims. These included: a) To continue and develop work on residue handling in back to back cotton and rotation crops b) To help in the completion of evolving guidelines for the control of diapausing heliothis pupae in back to back cotton, cotton to fallow and in the direct drilling of rotation crops in standing stubble c) To extend ideas and concepts above into growing areas and leading grower operations to help industry adoption d) To offer and implement suggestions for mechanical improvements and new technological developments across the industry, including manufacturers and developers e) To ensure the guidance systems developed in previous projects are commercialised and fully released to the farming community f) To produce a MACHINE-pak that details existing and new techniques and equipment for the Australian cotton industry.

Plants respond to infection by increasing the levels of several proteins, known as PR (pathogen response) proteins (Ward et al., 1991). Some of these proteins have been shown in vitro and in vivo in transgenic plants (eg Broglie et al., 1991) to have antifungal activity. Synergism between different antifungal proteins in transgenic plants has been demonstrated (Jach et al., 1995; van den Elzen et al., 1993) so the expression of several genes for antifungal proteins is probably required for significantly improved resistance to fungal pathogens. This work has received generous support from the CRDC for several years. This has allowed the generation of several batches of cotton lines expressing putative antifungal proteins. Several lines with increased chitinase activity (around ten times background levels) and expression of elevated levels of osmotin were generated. We believe that disease resistance is important for improving overall yield under low disease pressure and avoiding yield loss in cases of severe infection. Therefore evaluation of ) this material that has already been generated was of importance to the cotton industry. The main goal of this project was to generate seed for glasshouse and field testing against Verticillium and Fusarium wilts and to undertake these tests with the best chitinase-expressing material
