The impact that viruses can have on root crops has been very evident this season and cereals are no exception to the rule, with BYDV an increasing threat. CPM finds out how researchers are developing systems to help growers manage risk to cereal crops. It’s when aphids begin to move within the crop that infection spreads. By Lucy de la Pasture Aphids may do limited damage to cereal crops themselves, but the viruses that they can carry may prove devastating. One of those is barley yellow dwarf virus (BYDV) which can cause significant economic damage, with yield losses of more than 50% possible. An exciting new AHDB research project is underway that aims to help growers improve BYDV management and it’s entering its second year this autumn. Two important developments have taken place which mean BYDV management has to change, explains ADAS’s Dr Sacha White, who is leading the project. One of these is the recent loss of the neonicotinoid seed treatments that were so effective at protecting the crop from virus transmission from the moment they emerged in the autumn. Resistance to pyrethroids is widespread in grain aphids, one of main vectors of BYDV. The complicating factor is…
