Turnip yellows virus (TuYV), formerly known as Beet western yellows virus, is a very important pathogen of vegetable brassicas and oilseed rape. It is spread by the peach potato aphid (Myzus persicae).
This data is collected as part of project ‘Developing integrated approaches for pest and disease control in horticultural field crops’ with funding from the BBSRC Horticulture And Potato Initiative (HAPI).
