We all do these things Jayne so you're not alone. Probably too late to sort, as the others have said. Lots of water is about the only chance. I don't use Weedol either Verd - I'm sure someone will know and can advise though.
I think I'd give the plants a couple of weeks and if they're not recoverable, dig them out, pop some plants in pots to fill the gaps - just to be on the safe side - and wait till autumn, or even next year, to replant the areas.
