OBJECTIVES OF TRAVEL To attend the 1 lth Biennial Conference of the Australasian Plant Pathology Society (APPS), present a paper on recent research from CRDC Project DANlOOC and attend a practical workshop on disease

The CSIRO cotton breeding program based at Narrabri has been very successful in developing varieties adapted to all cotton production regions in Australia.

The commonly used Micronaire value for cotton is related to both fibre fineness and maturity. There is a need for a new measurement technique to separate these.

The research had three parts: * Quantify the V AM fungi at depth in the soil * Determine the rate of colonisation of roots of cotton by V AM fungi.

A variety of proteins were purified from cotton seeds and were analysed by amino acid sequence determination (automated Edman degradation) and by state-of-the-art electrospray ionization mass spectrometry (ESMS).

This project aimed to estimate the capacity of Helicoverpa armigera to develop resistance to INGARD cotton, to examine the possibility of cross-resistance to other Bacillus thuringiensis (Bt) toxins and to elucidate t

This project helped to identify the factors that affected the efficacy of transgenic Bt cotton plants to control Helicoverpa punctigera and H. armigera.

The results of disease surveys have indicated a declining incidence of Verticillium wilt and seedling diseases and an alarming increase in the prevalence of Fusarium wilt, black root rot and Alternaria leaf spot.

The objectives of the project were (I) to evaluate potential biocontrol agents for seedling disease control, (2) to evaluate potential biocontrol agents for the control of Verticillium wilt of cotton and (3) to develo

Development of sustainable, efficient, integrated weed management systems for cotton production is the primary goal of the weeds programs (CRDC and CRC funded).

We have developed a reliable and cost-effective plan for deciding whether a crop has sufficient green mirids to warrant controlling them.

The silverleaf whitefly (SL W), Bemisia tabaci B-biotype, was first discovered in Australia in 1994. SLW is a major pest of cotton in many overseas countries and poses a considerable threat to cotton in Australia.

The aim of this study was to (1) improve our understanding of predator responses to prey, predator/prey interactions and factors limiting their efficacy in cotton systems, (2) improve the performance of Envirofeast pr

This project was to provide the basic technical support at the molecular level for CSIRO' s cotton breeding program to develop new transgenic cotton varieties with improved agronomic characteristics.

To ensure the viability of cotton research into the ears of agronomy, entomology and pathology by NSW Agriculture staff at the Australian Cotton Research Institute

The aim of this project is to evaluate annually a large number of cotton breeding lines and cultivars for yield and quality characteristics in Queensland in collaboration with the CSIRO cotton breeding programs at Nar

The overall aim of the project was to carry out research to aid the safe and rapid adoption and implementation of genetically engineered viral insecticides into the Australian Cotton Industry.

Project Objective Year 1: To order and purchase a new file server and install it at ACRI.

Objectives The dynamics of beneficial insect communities in cotton agroecosystems and the role of alternative crops in producing natural enemies for cotton * To quantify the seasonal phenology and abundance of key ben

Nine insecticide trials were carried out for control of silverleaf whitefly. The evaluation of control performance was greatly hampered by the considerable variation in whitefly numbers.
