    The cost of weeds to Australian agriculture is estimated at an annual $4 billion through crop yield loss and seed contamination. This estimate continues to rise with increasing crop value, and as herbicide resistance becomes increasingly more widespread. Currently, 25 different weed species display at least some level of resistance to widely deployed herbicides. Wheat is particularly vulnerable with the commonplace use of glyphosate as a chemical control of annual ryegrass and other weeds in direct drilling farming systems. Other herbicides may be used to assist in ryegrass control, but ryegrass has the capacity to develop resistance to other herbicide groups resulting in multiple genetic resistances. Indeed, herbicide resistant ryegrass is common throughout Australia and it is poor control of ryegrass that makes wheat the weakest link in weed management in Australian cereal rotations.

    OtherEnsuring growers, advisors and industry stakeholders are informed about the latest research and development outcomes in their quest to improve on-farm profitability is a key role of the annual Grains Research and Development Corporation (GRDC) Updates. The GRDC Updates deliver research direct to growers, agronomists and industry. This year the Updates will offer information from the latest research and development from short- and medium-term investments that address on-farm priority issues from farming systems, agronomy, soils, weeds to pests and diseases.
