Weeds of pastures and field crops in Tasmania: economic impacts and biological control

The primary aim of this technical bulletin by By J.E. Ireson, J.T. Davies, D.A. Friend, R.J. Holloway, W.S. Chatterton, E.I. Van Putten and R.E.C. McFadyen was to provide a revised assessment of the cost of weeds to Tasmanian pastures and field crops as well as identifying the weeds that are having the most significant impact on Tasmanian agriculture. It also reviews the current status of all weed biological control programs that have been conducted in Tasmania against some of the major weeds and provides a case study of the successful biological control program on ragwort. The document should serve as a useful reference for those involved in weed control both within the state and nationally.

An economic evaluation of the research benefits and returns on investment in the Invasive Plants Cooperative Research Centre

This report by by Randall Jones, Garry Griffith and David Vere (NSW DPI) evaluates the economic return on benefit based on seven years of CRC work.

Weeds in winter pulses: integrated solutions

Guides by Di Carpenter and Annabel Bowcher for the management of weeds in winter pulse crops, looking at the whole farm business and developing strategies involving a wide range of techniques. These publications provides an overview of all aspects of managing weeds during the pulse phase of crop rotation, including what pulse species to choose, weed impacts on pulse production, problem weed species by state, optimisation of the competitive ability of pulses against weed species and weed management using an integrated approach drawn from the suite of available chemical and cultural control methods.

The economic impact of weeds in Australia

Economic research undertaken by J Sinden, R Jones, S Hester, D Odom, C Kalisch, R James and O Cacho in 2003 established that the annual cost of weeds to Australian agriculture exceeds $3.5 billion, and may be as high as $4.5 billion per year.

This peer-reviewed publication edited by H Spafford Jacob and DT Briese contains the proceedings from the Weeds CRC Biological Control of Weeds Symposium held in Perth on September 13, 2002.

Weeds CRC impact assessment

This report by the Centre for International Economics highlights the CRC’s achievements up until 2001 and the avenues through which the CRC’s work will reduce weed costs over the longer term.

The specification, estimation and validation of a quarterly structural econometric model of the Australian grazing industries

This model’s development by David Vere, Garry Griffith and Randall Jones closely follows the structural modelling procedures previously adopted in NSW Agriculture and represents an aggregation of that research into a single entity.

An integrated economic system and the farm and industry benefits of improved weed management

This paper by DT Vere, RE Jones and GR Griffith presents a brief review of the methodology of production systems modelling and provides details of the farm and industry modelling methods adopted in the construction of the integrated models. Examples of the application of this modelling system are presented.
