Abstract
Synthetic herbicides have been used globally to control weeds in major field crops. This has imposed a strong selection for any trait that enables plant populations to survive and reproduce in the presence of the herbicide. Herbicide resistance in weeds must be minimized because it is a major limiting factor to food security in global agriculture. This represents a huge challenge that will require great research efforts to develop control strategies as alternatives to the dominant and almost exclusive practice of weed control by herbicides. Weed scientists, plant ecologists and evolutionary biologists should join forces and work towards an improved and more integrated understanding of resistance across all scales. This approach will likely facilitate the design of innovative solutions to the global herbicide resistance challenge.
Highlights
Since the late 1940s, synthetic herbicides have been used in agriculture on a global scale to control weeds
In February 2013, over 350 delegates from 30 countries convened at the international ‘Global Herbicide Resistance Challenge 2013′ conference, convened by Stephen Powles (Australian Herbicide Resistance Initiative, University of Western Australia), to participate in a multidisciplinary forum which focused on the state of knowledge and management of weed resistance to herbicides
Conference participants generally shared the common view that a deeper understanding of the genetic and mechanistic basis of non-target-site resistance (NTSR) is a high priority in herbicide resistance research
