Abstract

The cost of weeds to Australian agriculture is estimated at an annual $4 billion through cropyield loss and seed contamination. This estimate continues to rise with increasing crop value, andas herbicide resistance becomes increasingly more widespread. Currently, 25 different weedspecies display at least some level of resistance to widely deployed herbicides. Wheat is particularly vulnerable with the commonplace use of glyphosateas 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 inmultiple genetic resistances. Indeed, herbicide resistant ryegrass is common throughout Australiaand it is poor control of ryegrass that makes wheat the weakest link in weed management in Australian cereal rotations.
