Just checked my Broad beans at allotment and some of them have leaves turning grey/black. :shock: (They also had a few holes with the culprit attached - sorry pellets for him and his pals.) Any thoughts on cause of disease/ virus I thought broad beans were only troubled by black fly and they're not around. I have a plastic barrier close to the plants to reduce blast from wind coming across plot.
Welcome any ideas not seen it before :?
Cheers HH

blast from reduced winds coming across plot perhaps?

broad beans can get choclate spot - especially after severe weather - and normally due to a potash deficiency.
bordeaux mixture might help :wink:
beans are also suceptible to foot / root rot as well as grey mould - with all the wet weather - and if your soil is not well draining - might be the cause

Even at this time of year? I thought a fungus would only attack when the weather warmed up; I've never been able to over-winter broad beans to advise.

I don't know what temperature they need, but it's very mild here, Wiggy.
A few of my BB are in bud. :oops: :oops:

I would put my money on Wg's first post, wind scorch, the wind chill at night is cutting and if they are in the open I reckon its that. I really cant see it being mould if they are outside it might seem mild but you stand there all day and night with nowt on. :shock:

Thanks everyone I think it could be grey mould it is 13 degrees C here at present which is very warm for time of year. Think I will remove affected plants and move wind break to lower humidity.

How about a piccie please?
Even weeds have got brown patches on the leaves in winter - their main goal is only to survive.

I checked me fact sheets out about this. Chocolote spot and grey mould are more common on autumn sown beans, starting to be prevalent from mid- winter. And they commonly follow each other, it says.
But the description 'black' I still find confusing.
