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.

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.

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

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

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.

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

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

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.

One hundred & seventy people were given training in soil assessment and management, Hands-on training in soil management was given to one hundred & seventy members of, the Australian cotton industry at a serie

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.

During January to June 1999 tests were carried out to determine infectivity of the existing geminivirus in Australia in cotton.

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

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

PROJECT OBJECTIVES: * To use standard bioassay techniques to establish the particular resistance I susceptibility profiles of Australian native and B-biotype B. tabaci.

Following standard CSIRO Tender Procedures, a new John Deere 8100 Tractor was purchased from Peel Valley Machinery Service, Narrabri against CSIRO purchase order number BP004778 dated 9September1999 at a cost of $121

Original aims of the project are listed below: (i) To continue evaluation of the insect resistance of a range of cotton genotypes, including lines derived from crosses of promising HPR varieties with high yielding com

The key elements of the research were l) to determine the distribution and diversity of parasitoids of Bemisia tabaci already in Australia 2) to determine whether these parasitoids have the potential to control SL W.

Project Aims: Purchase a new portable photosynthesis system to support projects investigating cotton responses to waterlogging, heat tolerance, insect damage, nutrient supply and exogenous hormones

This report examines available deposition data and assesses the performance of two mathematical models in predicting the relative drift profile of UL V and EC formulations of endosulfan as used in the Australian cotto
