broad bean problems

The only thing I can think of would be blackfly but there's most likely someone who knows a great deal better!

I have blackfly on mine - but only recently on first sown batch and they have been cropping well. Second lot have failed to develop beans where blackfly is very heavy but that's only on a few plants out of the total... I've now sprayed them so expect the problem to be under control.

Hopefully someone with better advice will come along soon! 

Thanks for the replys I don't think it was Black Fly as I had very little untill late on, I had bad Black Fly last year very early on but still went on to get a very good crop. Thrips are not some-thing I had heard much about but the sites I have looked at say that they make holes in the leaves and flowers and I had no sign of this. It's not just a few plants I am talking about but 2 1/2- 15 foot rows. I was told it could have frost at the wrong time but I thought Broad Beans were fairly hardy. Some of the plants had 10-12 beans set but stopped at around an inch long I wondered if the plants could not support them all. Cheers Clive
