While the recent cold weather has impacted aphid numbers and activity, the pressure earlier in the season means that there is a level of primary infection in some crops which could escalate rapidly if aphid numbers build significantly in spring... According to NSW Department of Primary Industries plant pathologist Joop van Leur, testing to identify the virus species present in faba bean is still in progress early indications are that the main virus present is Bean yellow mosaic virus (BYMV) with smaller incidences of Bean leafroll virus (BLRV) and other luteoviruses... Consultants and growers are being urged to monitor aphid populations closely in the lead up to spring and implement control strategies early to avoid severe virus infection later in the season...

He added that the use of the DNA based soil testing services prior to sowing was showing potential in identifying crown rot in the northern region, but required a stringent sampling strategy... "In recent years, use of the DNA based soil testing service PreDicta B has proved a reliable indicator of nematode populations but question marks have been raised by industry over its accuracy in assessing crown rot risk within the northern region," Dr Simpfendorfer said... "PreDicta B is a good technique for identifying the level of risk for crown rot and other soil-borne pathogens prior to sowing within paddocks but requires a dedicated sampling strategy and is not a simple add-on to a soil nutrition test...
