Spray with something systemic over here we use bugclear, and if the leaves are unsightly then prune these back and a new flush of foliage will be sent up.

thank you , I tried seven today and a small cloud of little white bugs lifted. I may have to do the big cut back...

Shouldn't think so - Roseclear is for treatment of black spot which is a fungal disease. Could you put up a photo of the damage?
