Summary

Herbicide resistance is a major risk to crop production in Australia.

No-till cropping is highly reliant on herbicides for weed control. The loss of herbicides to resistance will increase costs to growers, increase the difficulty of management and threaten the sustainability of farms.

This project seeks to prolong the life of glyphosate, paraquat and Group I herbicides through better understanding of the herbicide-resistance problem, better decision making and demonstration of resistance management strategies in a whole-farm situation. Discussions will be held with other users of these herbicides where resistance may impact on the grains industry to develop better practices and reduce the risk to grain growers.

This project will develop better understanding of resistance to glyphosate, paraquat and Group I herbicides to better inform weed management. The project will develop a range of tools for farm advisors to improve their confidence in decision making with respect to reducing the risk of glyphosate, Group I and paraquat resistance. These will include risk assessments, case studies and scenario-exploring tools.

The project will investigate the potential for alternatives to these herbicides, concentrating on knockdown uses and Group I herbicides for Brassica weeds that may prove useful in Australian agriculture. The project will discuss with commercial providers the potential for new herbicide registrations. It will establish farm-advisor learning groups to work on the application of the research in local areas where resistance is already a major problem and to improve adoption of research outcomes from this and other projects.

The outcomes of the project are aimed primarily at farm advisors, but will also be of benefit to grain growers and others in the industry.
