This includes survey work to evaluate the frequency and distribution of herbicide resistance in a number of crop weeds (wild oat, ryegrass, brome grass, barley grass, conyza and wild radish) in the Western Australian grain belt. Other surveys and research includes; farmer surveys on the extent of weed seed contamination present in crop seed sown in Western Australian grain-belt farming systems, seed dormancy in annual ryegrass and the characterisation of herbicide resistant weed populations where resistance is rare e.g. glyphosate resistance in ryegrass.
