Powdery Mildew

In case you were wondering how powdery mildew differs from Fireblight here is a photo of powdery mildew on Dahlias on the older leaves. Not a pretty picture but definitely not fireblight!

On trees powdery mildew often looks like a very faint dusting of white on the leaves with some cupping of the leaves.
