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 with funding from the BBSRC Horticulture And Potato Initiative (HAPI).

Still many diamond–back moths around
Twitter and particularly https://twitter.com/MigrantMothUKcontinues to report huge numbers of diamond-back moths all over the country. The picture below shows some of the moths captured in a light trap in south Warwickshire last night - next to a field of oil seed rape.
