A new BYDV tolerant variety of winter barley has proved beneficial in the fight against the infection, according to trials carried out by Frontier Agriculture this summer. Charlotte Cunningham reports. BYDV is spread by aphids and can result in significant yield losses, or even plant death. The ban on the use of neonicotinoid seed treatments, which were previously used to manage BYDV infection, has left farmers and their advisors seeking alternative management strategies. However, Frontier Agriculture #3DThinking trials harvested this summer have demonstrated that a new BYDV tolerant variety of winter barley – KWS Amistar – could prove useful to growers in areas at high risk of barley yellow dwarf virus infection. 6-row variety KWS Amistar is a conventional 6-row variety containing a tolerance gene which means plants will still get infected, but will be able to tolerate the virus and grow normally, with minimal yield loss. Jim Knight, seed business development manager for Frontier says: “We included these trials in our #3DThinking programme because we are keen to help growers solve the puzzle of crop management now that we can no longer rely on insecticidal seed treatments such as Deter.” Varieties with an inherent tolerance gene are one way to do…
