    It did this last year too...bright, almost flourescent orange spots on the stems and underside of many of the leaves. Doesn't look like rust to me, but I don't know quite what it is.

    Sorry about the crappy photos...best I could do at 9.30pm.

    Do you advise DDT?

    I did wonder about that, but the spots are furry and very irregular size and shape....so I'm not sure.

    If you can dettch them with a thin blade then it's probably scale. If the spots are more firmly rooted then I would think its fungal. Not sure really??

    Try a weak washing up liquid solution, scale insects hate it.

    I think it's some sort of Rose gall wasp, not sure which one but they tend not to do alot of damage and can make interesting talking points.

    Found a link to a page about galls in gerneral, hope this helps? http://www.hainaultforest.co.uk/5UK%20Galls.htm

    Here are some better photos taken this morning.

    So the little flecks look a bit like rust, but they're powdery and dusty...like the big specks, which look nothing like rust to me.

    I think I've solved the problem, and ten house points to those that were saying rust.

    It does appear to be a type of rust - http://images.google.co.uk/imgres?imgurl=h...sa%3DN%26um%3D1.

    I shall get my Rose Hammerite out.

    Iwas intrigued to see in a gardening magazine recently a warning to the effect that under EU regulations relating to garden pesticides, the use of dilute washing up liquid as a garden pesticide is unlawful as it has not been specifically approved for that purpose!

    God preserve us.

    i agree defo rust.if the outbreak is on a small scale try smothering the putsules with a dab of vaseline.

    good hygeine is the key to prevention.make sure you clear all plant debris after leaf fall.

    it's not really one of the worst diseases to affect roses.

    This is correct to a degree, but it would be at the growers risk rather than unlawful. It would be unlawful for a washing up liquid manufacturer to claim a pesticidal action.
