Susceptible to Mildew. From page 438 of Peter Beales Roses - An illustrated encyclopedia and grower's handbook of species roses, old roses and modern roses, shrub roses and climbers by Peter Beales (ISBN 0-00-272178-3):-

"Powdery Mildew attacks roses from early summer onwards. The first signs are small patches of greyish-white powder, usually near the top of the young growing shoots and on the succulent young leaves.The young leaves curl, distort and fail to develop. Well-nourished plants will suffer less than undernourished one. Systemic fungicides should be sprayed well in advance of the appearance of the disease on known susceptible varieties. Over-use of nitrogenous fertilizers is often the cause of mildew, especially when mid-summer application leads to excessive growth in the autumn. Mildew may also follow summer drought, so keep the roses well-watered during such weather." I would recommend a sprinkling of Maxicrop Seaweed Meal and then a mulch of 4 inch deep Cow Manure and Spent Mushroom Compost applied in the Spring to provide long term nitrogen and to prevent the ground from drying out during the heat of the summer. Remove the mulch, flowers and leaves in late Autumn to prevent any disease spores from overwintering and attacking the roses the following year. Always water from below, keeping water off the foliage. Remember to space the roses and companion plants properly so they receive adequate light and air circulation.

Downy Mildew
"Downy Mildew affects roses grown under glass, especially those grown in pots. It takes the form of dull brownish or sometimes bluish patches on the surface of mature leaves, which can also spread to the stems. Infected leaves become limp and fall. The disease is usually brought on by extremes of day and night temperatures, especially when linked to bad ventilation in greenhouses and conservatories. Some control can be achieved by the use of similar fungicides to those used against powdery mildew and black spot. The disease seldom attacks outdoor roses."
