what kind of disease on my lorepetulum?
Two of my well established Chinese fringe shrubs seem to have a disease.

I'm not sure of the symptoms of your shrubs.
They may suffer from Powdery Mildew in moist growing conditions or Scale insects or Spider Mites.
A fungicide for Powdery Mildew treatment and a insecticidal soap if you see Scale or Spider Mites is a good plan of attack.
