Key points Ideal growing conditions could lead to a large brome grass outbreak in Western Australia this season. Brome grass control is made difficult by a persistent weed seedbank, late germination and unpredictable pre-harvest seed shed. A year-round, multi-season integrated weed management strategy is the only successful approach to controlling brome grass. Control strategies should be based on WeedSmart’s ‘Big 6’ IWM principles. With much of Western Australia’s grainbelt enjoying higher than usual soil moisture heading into winter, growers are being urged to consider their brome grass control strategy and plan for a long campaign. Brome grass (Bromus diandrus var. rigidus or B. diandrus var. diandrus) is widespread throughout the WA wheatbelt. While there is more than one variety of B. diandrus, it is not possible to distinguish between them in the field. The species is highly adaptable, with broad variation in dormancy, germination times and seed production.
