I direct sow my broad beans into the veg plot at the end of October, pinch out the growing tips when the first beans have set and never have a problem with blackfly. We've had a fantastic crop this year, have eaten loads and have loads in the freezer. They've finished now and I'm just about to pull them up and plant the purple sprouting broccoli plants in their place.
I've also never had a problem with blackfly on runner beans (so far - fingers crossed ) but if I get them on other plants I just wash them off with a jet from the hosepipe.
