Roles and responsibilities
2) Exploring innovative herbicide solutions for improved control of multi-resistant weeds and delay weed resistance evolution. For example, the efficacy of old and new herbicides used in combination or mixtures should be carefully assessed to exploit possible synergies between the two compounds to obtain greater herbicide efficacy in weed control.
Mixtures of different herbicide modes of action are known to effectively delay resistance. However, a sound knowledge of the weed biology, physiology and biochemistry of the herbicide-weed interaction is required. In AHRI we have all the necessary knowledge to deduce which combination of compounds (e.g. safeners, synergists, mixtures of herbicides and insecticides or fungicides) may result in synergistic interaction and much improved weed control of multi-resistant weeds as well as proactively delay the evolution of resistance to new herbicides. This research can synergize with current GRDC investments and attract investments from multi-national and local corporations.
3) Establish a specialized centre at UWA to conduct herbicide efficacy testing and quantify resistance levels on weed seed samples directly provided by farmers. These activities will allow a greater focus on local resistance issues and provide direct support to growers.
The envisaged research will create continuous opportunities for research projects to be conducted by undergraduate Honours, PhD students and postdoctoral fellows. It will create unique opportunities for AHRI to be more proactive in the Australian grains industry, collaborate with the public and private sectors and generate revenues to allow employment and training of young Australian students and researchers.
