Lilac Bark Problem

geryoung
15 years ago

Need help. Whitish/gray mildew patches beginning at the base of my lilac covering the branches and bark but not on the leaves. When the mildew is wiped away there appears under the mildew a yellowish substance and the residue from wiping is white and granular/particulate. Leaves have started to fall. Would love to know what I am fighting and how to treat it.
