The objective of this study was to examine the distribution of tyre imposed stresses, soil displacements and soil mechanical properties as function of the soil surface geometry.

With CRDC permission, the travel award was transferred from Dr Skerritt to Ms A Hill, the diagnostics project leader; there was, however, not a change in itinerary.

The inaugural Australian Rural Leadership Program was conducted during 1993 and 1994.The rationale for this innovative concept was to form a strong bond between the 30participants, enrich their leadership capabilities

Project Objective: To provide the basis for improved crop and soil management in dryland cotton production systems by: 1. monitoring on-farm performance of cotton-based dryland cropping systems; 2.

In Australia, management of cotton pests is insecticide based.

Objectives of visit: To attend the 13th Conference of the International Soil Tillage Research Organization (ISTRO) and present paper entitled "Effect of soil preparation method and cotton-based cropping system on

In Australia, management of cotton pests is insecticide based.

This study was initiated to quantify the impact of those predators commonly found in Australian cotton fields and thereby reveal the importance of the various predatory species in Helicoverpa pest management.

The comparative advantage1 of cotton production was examined for three production systems in the United States and four production systems within Australia.

Commissioned in November 1994, it was funded equally by the Cotton Research and Development Corporation (CRDC) and Sainty and Associates with a budget of $47 000 and the following work was undertaken: 1.

A paper was presented at the fourth international Trichogramma and other egg parasitoid conference titled 'Evaluating egg parasitoids for integrated pest management in Australian raingrown cotton.' Highlight

A growth disorder of cotton has been observed in irrigated cracking clay soils in fields at Galathera Creek, north of the Australian Cotton Research Institute (ACRI) for several years.

In March 1995 the Cotton Research and Development Corporation (CRDC) asked the Centre for International Economics to prepare a report on the cotton industry and its economic impact.

Two fields of cotton on two nearby farms in the Macquarie Valley of NSW which had different histories of weed management were studied to determine if weed seeds were being introduced via irrigation water.

This project aimed to continue the steady improvements in developing improved cotton varieties adapted to Australian growing conditions and markets

Cotton plants expressing the CrylAc toxin from Bt are near to commercial release.

The aims of the CRDC project CSE 29C were: - to optimise the design of recombinant Helicoverpa viruses with increased insecticidal activity (Activities 1 and 2 of the overall program above), - to develop suitable larg

The aim of this study was to complete the development of a mirid feeding bioassay to facilitate screening and characterization of proteinaceous toxins.

Disease surveys in November and March of each season have been undertaken on a regular basis since 1983.

A large collection of microorganisms with over 2000 isolates has been established at the Australian Cotton Research Institute for the purpose of identifying potential bio-control agents and developing biological contr
