Integrated approach key to potato virus Y strategy

摘要

Potato Virus Y is dealt with by a zero-tolerance policy at Albanwise Farming in North Yorkshire, where the specialist operation has 40ha of processing ware and 360ha of seed potatoes in the ground for 2021, consisting of 31 different varieties.A combination of chemical and non-chemical strategies is used, with new techniques that make good use of biology and ecology being given every chance to bring improvements.Greater awareness of the virus threat has been in place for the past few years, ever since the summer of 2018 when the combined effects of high aphid numbers and drought led to rising infection levels in the following year's ware crops.
