We planted some potatoes for Christmas, Vivaldi & Lady Balfour. I went up on Thursday & they appear to have blight. Planted late August/early Sept. Are we likely to get any potatoes at all or should we just dig them up? Would it be OK to follow on with broad beans where the potates have been?
Have never heard of broad beans being affected by blight, and there may be some tiny spudlets under he ground..
I would remove the blighted leaves and keep an eye on them for a bit. I agree with Delboy about the broad beans too.
Only the potato family is susceptible, so beans won't be affected.
This problem is very common over here in France, inevitable in fact.
It is brought about by humid conditions, warm and damp.
My knowlegeable French neighbours told me to spray Bordeaux fungicide every single week while the weather is like that, and yes it helps a lot.
However, it does spread to the tomatoes, and also my cabbages which also need that spraying.

Whatever your cabbages have it definitely isn't Potato Late Blight.... it struggles to affect the whole of the solanaceous family (there are resistant spuds and tomatoes for starters)..... there are plenty of other things that look a bit like blight that might attack a cabbage though and would appreciate the same conditions though and treatmetn would be similar...

Welcome to A4A Vanwin :)
Cabbages certainly rot, and while I think it's probably bacterial, one rot can look the same as another. If I'm right, fungicide won't help.
If it's bacterial they'll want anti-biotic ;D
