Answer: Spray the foliage regularly with Triforine, Rose Shield or Rose Gun.

Water the plants in the morning rather than in the evening. Always water at the base of the plant, rather than on the leaves. In winter, spray the leafless plant with lime sulphur immediately after pruning. Grow rose plants in an airy position in full sun. Choose vigorous varieties. Move to a drier and less humid climate. Regular feeding, manuring and mulching will help plants to resist disease.

Triforine
Rose Shield
Rose Gun.
