To discuss benefits and practicalities of individual growers weed management tactics; and to assist others to decide if adopting similar methods would be beneficial on their property.
The practical implications of harvest weed seed control are a more resilient farming system with some insurance against further resistance evolution. The combination of effective herbicide use, plus harvest weed seed control techniques has been shown to reduce and maintain weed populations at very low densities. In cropping systems, low weed densities, regardless of their herbicide resistance status, allows flexibility in crop choice, seeding time and herbicide use. This flexibility provides growers with the capacity to readily adjust farming practices in tune with seasonal and market considerations.

Acknowledgments |
Many people have contributed to the development of this case study booklet and we thank them for their contributions and support. Thank you to the Albany Port Zone Regional Cropping Solutions Network who identified potential case study participants and provided valuable feedback in the development of the project. They identified harvest weed seed control as a major issue for the Albany Port Zone and contributed GRDC funds to see this work be conducted. Thank you to Alexandra Douglas who project managed and conducted the case study interviews, along with Jane Kowald from Southern DIRT. Alex’s experience in weeds and herbicide management is exceptional. Thanks to the Australian Herbicide Resistance Initiatives team (AHRI), particularly Brogan Micallef and Peter Newman who provided financials and background for the project. In particular, we thank the growers who participated and shared their experience of harvest weed seed management. They are Barry Gray, (South Kukeri |
