Hi

My broad beans have a very bad infestation of Black Fly.
I am finding it almost impossible to get any kind of pesticides from
Garden Centres etc.

Does any one have any idea what I can do please?

Some one on the allotment site swears by boiled Rhubarb water. Claims it to
be a good poison. If so any one know the mix please?

regards
Ged

Not a lot of help for now but I would also advise, from practical
experience, that autumn sown broad beans are considerably less affected
by black fly.

If you do get them, some washing-up liquid in water helps clear them and
prevents them coming back - unless you have a large area, in which case
it is going to get very tedious;-)

Yeah, having to do all that washing up first.....
