To investigate alternative break crop sequences and cereal herbicide control options that can increase profitability and reduce brome grass populations in the Mallee.
In years with high summer rainfall, growing break crops is low risk and is an effective management strategy for reducing weeds, while growing profitability. Two year breaks are better than one at achieving favourable returns and reducing brome grass populations. The best brome grass control and gross margins were achieved by two year rotations of Clearfield canola/vetch and continuous Clearfield wheat followed by wheat.
