Dr. Chris Preston is Associate Professor of weed management at the University of Adelaide. He works on understanding and management of herbicide resistant weeds. Current research projects include IWM in southern farming systems to combat herbicide resistance, Improved herbicide efficacy and longevity in southern no-till farming systems, Improving IWM practice of emerging weeds in the southern and western regions and Mechanisms, Evolution and inheritance of resistance. He also chairs the Australian Glyphosate Sustainability Working Group.

The research of the weed science group at the University of Adelaide is focussed on better managment of weeds in agricultural cropping systems. Areas of current research activity include: the evolution, biochemical mechanisms and management of herbicide resistant weeds, ecology and biology and management of emerging weeds in agriculture, gene flow from herbicide tolerant crops and its implications for farm management, risk assessment for weeds and herbicide tolerant crops and patterns of genetic diversity in weed populations.
