Barley grass control in a three year rotation at Esperance Barley grass is becoming an increasingly problematic weed in Western Australia. A GRDC funded project sought to increase adoption of integrated weed management tactics for barley grass, by working with grower groups to develop regionally appropriate rotations for optimal control. A survey indicated that in southwest Australia, many growers thought their barley grass was resistant to grass selective herbicides and may have developed late germination to avoid pre-seeding herbicides. In this area barley grass was a major problem in pastures, and often in break crops too. A three year trial aimed to investigate pre-emergent herbicides and autumn tickle in wheat in 2019, pre-emergent herbicides and crop density in barley in 2020 and grass selective herbicides and crop topping in pasture in 2021.
