GRDC Roadside Weed Management:
Tackling Resistance from Both Sides of the Fence
Project Overview
Cross Country Management is working with stakeholders across South Australia to reduce weed spread and herbicide resistance along our roadsides. This project (PROC-9177313) is funded by the Grains Research and Development Corporation (GRDC).
This three-year GRDC-funded project, led by Cross Country Management, brings together councils, growers, contractors, and government agencies to tackle roadside weed resistance across South Australia’s Yorke Peninsula and Alexandrina regions.
Roadsides are key pathways for weed spread. Through collaboration and evidence-based testing, this project aims to build a shared framework for effective roadside weed management - one that balances ecological, agronomic, and community needs.
Key Activities
Workshops
Six workshops (three in each region) will bring councils, growers, and agencies together to identify knowledge gaps and develop local action plans.
Weed Resistance Testing
Weed specimens collected from the regions will be tested by Dr Peter Boutsalis’ team to identify resistance risks. An interactive map feature may later display sample sites or results.
Collaborative Framework
The project will develop a model for effective roadside weed management that can be adopted more widely.
Case Studies
Two council case studies will be developed to share learnings and practical insights for other LGAs.
