So it's a fallacy that pinching the tops out prevents blackfly because the beggers are all over my stems and pods after doing just that. Ants too ! One solitary ladybird which gives a little hope but this clearly shouldn't be, especially as I have never had blackfly on broad beans until now. In fact I had an infestation on my nasturtiums last year. My pest problem just gets worse every year.
I have sprayed them with soapy garlic water.
