RWA in the northern grains region (July 2017)

Russian wheat aphid (RWA) is considered a high priority pest by the grains industry because of its potential to cause significant yield losses, particularly in wheat and barley, if not well managed.
It is inevitable that RWA will establish in the northern grains region, but we don’t know when we will start to see it in crops. In the 2017 season, it is important that crops are monitored more frequently than they might usually be to ensure early detection of RWA, should it occur.
