The position of Cotton Industry Development Officer (C.l.D.O) in the Macquarie Valley was implemented in 1993-94 because much good research generated at Narrabri was not being adopted by local growers.

The project was teminated by CRDC after two years and therefore could not meet its final objectives.

A Heliothis NPV formulation, GemStar, showed promise as a basis for successful selective, non-chemical insect control on cotton.

Pyrethroid resistance levels in Helicoverpa armigera have continued to escalate slowly to around 80-90% but endosulfan resistance has stabilised at about half that level.

To develop resistance management strategies for organophosphates (OP's) carbamates, insect growth regulators (IGR's) and new insecticide groups, such as the pyrroles based on a sound understanding of resista

aims of this study were to: obtain base-line data against 12 pesticides and to conduct an initial evaluation of the current resistance status of field-collected cotton aphid strains.

Aims: * Determine the economic impact of thrips on cotton and evaluate new means of control. * Evaluate the range and possible mechanisms of plant resistance to thrips and mites.

Objectives: A). To establish the uptake and partitioning patterns of potassium in cotton. B).

The effects of rotation crops and their management on soil properties, and irrigated cotton productivity and profitability were evaluated from 1993 to 1996 in some typical cracking clays (V ertisols) of the Namoi and

The objectives of this study were to: l) determine the role of soil instability and clay translocation in the formation of shiny-faced soil aggregates, 2) determine the roles of clay translocation and vehicular compac

OBJECTIVES 1993/4 Determine the common species of V AM fungi in the cotton areas of eastern Australia. Place the fungi in pot culture.

Over the period from 1990 to 1993, research was carried out investigating the regrowth of Australian cotton varieties after damage by haiI.

Objectives: To purchase a new nitrogen analyser in order to provide faster, more accurate analysis of cotton samples for a wide range of projects

This project upgraded the harvesting equipment for CSIRO cotton breeding experiments, particularly for those sites located off the Australian Cotton Research Institute.

Objectives (i) To provide full time management of the computer system at Australian Cotton Research Institute. (ii) To ensure optimal provision and use of computer resources for research and industry.

Objectives The aim of the project is to maintain the upgraded DEC computing facility at Myall Vale for the term of the project.

This study is a baseline biodiversity survey of the principal soil faunal groups found in irrigated cotton fields of north western New South Wales.

The goals of this research were: 1.

A vision guidance system has been designed, built and commissioned which steers a tractor relative to the rows of a crop such as cotton.

OBJECTIVES 1. To undertake a comprehensive sutvey of the Australian distribution of B. biotype B. tabaci . 2. To sutvey cotton for the presence of B, biotype B. tabaci 3. 4.
