My first infestation – and I’d been doing so well!
They’re attacking my broadbeans – all the tender young shoots covered in a mass of black aphids, and they’re starting to creep over onto the runner beans too.
They’re being farmed by ants and I have to admit it’s rather fascinating watching them running up the stems of the plants tending to their herd, while a couple of large ladybird lavae lurk on a leaf nearby, waiting their chance to move in on unattended stragglers – it’s all drama in my patch of dirt.
But, interesting though it is, it’s not doing my plants a lot of good.
I attacked them last night with a spray of water and liquid detergent but it doesn’t seem to have done much good. Perhaps it’s too dilute. I’ll give them another dose this evening with a stronger mix – maybe that’ll be more effective.
Anyone got any good tips for getting rid of blackfly?
