I have this one too…hadn’t ever seen it before but last year i noticed my red russian was growing strange but put it in the ‘unknown’ category, but all other brassicas were ok.
This year I just got back from holiday and see it has got into the PSB and Spring Caulis – will they recover – Kale is not so bad on multiple stems – but Caulis??
Do we need to use mesh to cover? Or fleece ok? WIll know now for next year.
thanks stew
