The extent of beet western yellows virus (BWYV), which has decimated canola crops in parts of South Australia, Victoria and New South Wales, has been mapped after extensive testing of samples provided by growers... A high incidence of BWYV associated with severe crop damage was confirmed earlier this season in canola crops in parts of SA and Victoria and unusually high infections were also found in several canola paddocks in NSW... Check for the build-up of numbers and any significant numbers of winged aphids in a population, which signals that flights may be about to occur," says Dr Umina, who is leading GRDC-funded research into insecticide resistance in GPA...

Beet Western Yellows Virus (BWYV) has caused unprecedented damage to canola crops in south-east Australia this season, causing the GRDC to fund emergency research to analyse the outbreak and limit potential damage in future seasons... For growers who have severely infected crops and will suffer significant losses this year, this means no more measures can be taken to address the outbreak in those crops... Where growers have only patches of infection, or have crops not affected, Dr Davidson recommends close observation of the aphids...
