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

This study used molecular biology approaches to investigate the biosynthesis of gossypol at the genetic level.

Objectives 1) Monitor the distribution of Fusarium wilt in cotton growing areas.

There were at least ten commercial fields of Ingard in the 1996/97 season with low efficacy pre flowering and requiring up to three insecticide sprays.

Objectives: 1) develop methods and techniques to assess soil salinity and identify irrigation inefficiencies at the field scale 2) develop inexpensive methods and techniques to estimate groundwater recharge rate on a

This project was designed to: * Review all available sources of analytical and research data regarding the binding and potential for remobilisation of endosulfan on bottom sediments * Based on the results of the revie

The Cotton Research and Development Corporation (CRDC) asked the University of Queensland to undertake a study to indicate socio-economic areas for research for the cotton industry.

The objective of this study is to examine the scope for further research irito certain quality characteristics of Australian cotton which are seen by many cotton industry participants as critical areas for improvement

The objectives were to provide a reliable method for quantifying the Cry1Ac produced by transgenic cotton plants and to use this to examine the changes in Cry1Ac levels during a field season.

Over the past two hundred years we have physically and biologically degraded many Australian streams.

These proceedings represent the outcomes of one of Australia's most successful R&D programs in natural resources management - minimisation of the impact of pesticides on the riverine environment.
