While I was weeding the plot this morning, I noticed sky blue marks
on broad bean leaves. On further inspection, I found the same on
French beans and peas. Some just spots, others about 5p size. It
wipes off with a wet finger. Any ideas as to what this could be?

I have no idea what this can be. BUT I would spray them with Provado
Ultimate Bug Killer. Yes I know that it is not friendly. But what
else can you do? Catch 22 situation. Beans or no beans? I hate these
decisions, but usualy spray if my plants are threatened.

Thanks Baz. Not keen on sprays if I can help. Will wipe all the
leaves clean tomorrow and see what happens.

Why spray with an insecticide?


Why not? Do you have a better idea?
I have found that a dose of Provado Ultimate Bug Killer does the job in
most cases where the cause/pest/parasite/fungi is not known. So if it works
for ME, it should work for others.
