Funding from the CRDC and NSW Agriculture allowed two District Agronomists from major cotton producing areas to attend the International Pesticide Application Technology Residential Course at the Gatton campus of the

Objectives of Travel. (i) to attend the XIX International Congress of Entomology, Beijing, China.

The main aim of this trip was to accept the invitation of the Organiser of the Symposium on "The Realities of Insecticide Resistance Management" (Dr George Georghiou) to present a paper on "Nine Years o

OBJECTIVES OF VISIT: * To attend the 1992 Beltwide Cotton Production Research Conferences organised by the National Cotton Council o. America which included the 52nd Cotton Disease Council.

The Project The Galathera syndrome affects cotton growing in the Namoi Valley, north-western New South Wales.

The aim of the project was to produce more virulent strains of a naturally occurlng entomopathogenlc nuclear polyhedrosls virus of Heliothis species.

Techniques for mass rearing egg parasites on eggs of the factitious host Sitotroga cerealella (Angoumois Grain Moth - AGM) were further developed and refined.

To develop, validate and implement a regional model of Helicoverpa population dynamics which considers the abundance, movement, oviposition, development and mortality of H.armigera and H.punctigera on all major hosts

Disease Surveys. Commercial cotton (Gossypium hirsutum L.) fields in the Mcintyre, Gwydir, Namol and Macquarie valleys of New South Wales were inspected in November and March each season.

This project identified a method of evaluating crop growth to predict yield response to Pix. * Two nutritional disorders were examined.

This is an on-going project of breeding cottons adapted to Australian growing conditions, diseases and pests and markets.

This project was a transitional one covering only one year to enable the incorporation of all our CRDC breeding projects under one submission (CSP 40C).

...

The findings from the research highlight a number of key issues which have already been outlined in my previous reports, however, these are repeated in summary as follows; * First, the results have confirmed the resul

Aposter was displayed by Ms Greenhalgh titled' Diagnosis of Soil structural Conditions', co-authored by David MCKenzie and Donald MacLeod.

The report indicates that there is a. good potential for cloud seeding in the Copeton Dam region.

This project was a feasibility study undertaken to determine if feeding of Helicoverpa larvae could be inhibited by polyclonal antibodies raised against gut tissues

An Orthman Mk II tracking unit was purchased in October 1991 prior to cotton sowing. The unit was successful in planting CSIRO's Leitch's block using a Kinze planter.

The Australian cotton industry has a long history of independent environmental assessments, demonstrating its commitment to monitoring and improving the industry’s environmental performance.

SUMMARY We have generated an antibody which is absolutely specific for H. armigera over H. punctigera. Specificity has been demonstrated in a number of ways. For example, the antigenic protein from H.
