Gangwon Agricultural Research Institute urges thorough control of vectors to prevent virus diseases in seed potatoes.

The risk of virus disease in seed potatoes is increasing... early prevention of vectors is important Disinfection of cutting tools · rapid chemical control at the early stage of occurrence and other preventive management Seed Potatoes The Gangwon Special Self-Governing Province Agricultural Technology Institute (Director Kim Dong-hoon) Potato Research Institute recently revealed that the risk of virus disease in seed potatoes is increasing due to climate change, which has shortened the overwintering period of virus vectors. To minimize the damage to farming households, they have presented preventive management tips. Currently, the viruses that mainly occur in seed potatoes are PVY (Potato Virus Y) and PLRV (Potato Leafroll Virus), both of which are transmitted by peach-potato aphids.
