A survey of cotton growers in 1992 (CRDC Project DAN 76C) showed widespread interest in the use of rotation crops, plus a need for more information about the benefits of legume rotations and the effect of rotation man

Objectives of the Study Tour For the duration of the study tour, I travelled with three other Australian Cotton Extension Officers.

Plants respond to infection by increasing the levels of several proteins, known as PR (pathogen response) proteins (Ward et al., 1991).

The focus of this project included several aims.

The current, first edition of the Best Management Practices Manual was developed as part of the joint research program"Minimising the Impacts of Pesticides on the Riverine Environment'', which was funde

This report is based on data gathered with the assistance of the membership of Cotton Consultants Australia Inc. (CCA) and covers all major cotton growing regions in Australia.

The handbook is divided into two parts and nine sections. It is anticipated that growers will want to refer more frequently to sections on ground spraying technology, safety, handling and application.

An industrial shed (9 x 12m) with concrete flooring and roller door access was constructed at ACRI in November 1998. The shed was sited in close proximity to other sample processing buildings.

Aim: To build a new glasshouse to provide a facility for basic research into plant I herbivore interactions

The project aims are: * Construction of additional cages to isolate field-collected strains of A. gossypii. * Establishment of additional base-line data.

This document is designed to assist users to develop a spray and drift management plan for their own farming operation, and applies equally to aerial and ground applications.

PROJECT OBJECTIVES To monitor pyrethroid, endosulfan, organophosphate and carbamate resistance in H. armigera and H. punctigera. from all cotton areas and to refine resistance management strategies.

Aims * To evaluate treatments that inhibit or restrict microbial degradation to cotton when the seed cotton harvest is delayed by wet weather.

Aims * To quantify the relationship between cotton plant spatial arrangement and soil water dynamics, and its effect on raingrown cotton yield and quality.

List the project objectives:Improve efficacy of pesticides by increasing the amount of spray reaching the target by reducing the losses due to evaporation of spray before it reaches the target.

Project Aims: 1. To provide full time support for computer hardware and network services at ACRI, Narrabri. 2. Facilitate the connection of industry users to on-line services developed by the Cotton CRC. 3.

Project Objectives 1. To quantify the effectiveness of trap crops. 2. To quantify the impact of trap crops on egg densities in surrounding cotton. 3.

This study has investigated the role of esterases in conferring pyrethroid resistance in Australian populations of the cotton bollworm, Helicoverpa annigera.

During the 1995/96 and 1997/98 cotton-growing seasons there was an inverse relationship between the population densities of dominant benthic macroinvertebrates and concentrations of endosulfan in the Namoi River.

HIGHLIGHTS * Participation in a conference with 632 delegates from 47 countries addressing all aspects of cotton production. * Presentation of a paper entitled ..
