This project has supported a wide range of cotton programs based at Narrabri covering all CRDC funded projects during this period.

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 aims of this trip were to initiate research on HaSV RNA designed to improve our ability to express insect viral genes in transgenic cotton, and to attend two important conferences relevant to the long-term biologi

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.

Aim of Travel: To participate in the Vlth International Co11oquium on Invertebrate Pathology and Microbial Control. The Colloquium also incorporated the Second International Conference on Bacillus thuringiensis

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.

From this visit I gained: 1. A good overview of the state of agricultural soil mechanics worldwide. I was struck by the lack of direction and novelty in some of the work in this field.

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

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

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

The purpose of the tour was to study and experience through participation the development and extension methodologies and practices used in the transfer and adoption of new technology in the American cotton industry b

This project had two major aims consistent with the overall goal of controlling Verticillium wilt in cultivated cotton (Gossypium hirsutum).

In this issue: COAG reforms; INTERIM REPORT: TOWARDS REDUCED FERTILISER LOSS IN IRRIGATED PASTURES

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.

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