blight on peas???

I planted my 3rd row of peas, (Hurst Greenshaft), on the 26 of June, hoping that I wasn't too late, now they seem to be covered, (and it has been getting worse over the last 2 weeks), with, for want of better words, with mildew, can I take it that this is the dreaded "blight", the beans next to them aren't affected at all. It was only an experiment in the first place, so to learned from it is very helpful. But is there a way of avoiding or controlling or even  banishing it, other than planting earlier. Thank you for all views, arh.

Thank you very much Hun, we live and learn, roll on next year, . arh.

I ate the peas,
