They're old leaves, often mildewed as Ladybird says. The new leaves are unaffected so the affliction is over. Fungicide might kill the fungal growth but it won't remove the dead mildew. Those leaves will die off soon, lots more new ones next year. Remove the leaves, problem over

Follow nut's advice - remove the damaged ones. If I sprayed every damaged leaf in my garden I'd never be doing anything else!
I live in west central Scotland - not where that photo is...
