Thanks Liriodendron. I agree in terms of using chemical controls on edible crops as I keep my garden as 'chemical free' as possible. I have taken your/RHS advice and cleaned fallen leaves, picked as many as I can of those affected, mulched and watered. On the weekend I'll get a foliar feed too. Unfortunately our weather is not helping. Dublin has had cloud cover and high humidity for weeks on end with only sporadic patches of sunshine! Thank you so much for your help!
