Hi all. New here, fairly new to working a veg patch. I’ve got blackfly On my broad beans, soapy water hasn't Helped. Will rose clear ultra damage the plant or get into it enough so as the beans won’t be edible. 
Many thank

    Don’t use Roseclear ... it’ll contaminate your beans it’s not for edibles! 🤮

    pick off the top of the plant that’s the part the aphids go for ... watch Fridays Gardeners World ... Monty Don showed how. 

    If the blackfly are on the pods squirt a hosepipe of water at them and wash them off. They’ll be fine.

    They are delicious ... a once a year gourmet feast. We had ours a fortnight ago. They were fabulous. I look forward to them
    every year. 😋

    The liquor from boiled rhubarb leaves, sprayed from a household spraygun will do it.

    It may well work @nick615, but it is toxic ... and I prefer not to spray toxic stuff on my food  ;)

    I respect your caution, Dove, and I've never seen an aphid since moving to Ireland in 2007.  However, it's a measure I've used back in Sussex, where I wasn't so lucky, with no ill effects.  I work to the principle that I spray the leaves (which we don't eat) and any spray that does get on the pods can't transfer inside to the beans.

    Ah, but I take the tops off and cook and eat them ... a gourmet delight just once a year ... and then we get no aphids either. 🍽

    If you have a sprayer with a strong jet hold the top of the plant and power hose them off.

    Or just use your fingers.

    I’m struggling to control blackfly this year. I pinched out the broad bean tops just as the blackfly started to arrive, but they’ve gone wild. I feel like I’m squishing them and blasting them with the hose as much as I can, but they keep coming and have now spread to my courgettes and french beans. 

    The broad beans are fairly resilient, and the beans are still forming (just a bit wonky) but the french beans seem to suffer much worse, as the growing tips get quite deformed.

    Dilute washing up liquid didn’t do much, and I don’t have any rhubarb. Any other suggestions?

    I have come to the conclusion that there doesn't seemed to be many ladybirds about this year, we had a few early on but they have seemed to have vanished,haven't seen one at all over the last month or more.Last year we had loads of them also the ladybird larva the  kept my blackcurrant free and my broad beans free of black fly.
