white powdery oval (worm shaped) on back of leaves
I have a shrub in the yard that has masses of white fuzzy (powdery) shapes on the back of the leaves. I suspect there may be a bug under the fuzz but haven't seen one yet. When I rub the leaf the white shape rubs off like powder.
As well, and I'm not sure if it is connected....there is a black residue/mold? on the tops of the leaves. I've done a ton of google searches and image searches and have found nothing that matches.
Does anyone know what this might be and how to deal with it?
Many thanks!! Deanne
