Oh, you have sooty mold. That is caused by the honeydew from aphid
infestations. The mold thrives on the sugars (carbon) in the honeydew, which
is essentially the aphid poo. Feel around on some of the foliage. If you feel
something sticky, that's your problem. If you take care of the aphids, the
sooty mold will also go away.

Are your crape myrtles under a larger tree which may have an aphid infestation?

The fungus that is on my plants is the dark colored, not the white. Will
that make any diffrerence?

Though neem oil is deemed appropriate for pesticidal use, it can also
cause
death to beneficial insects. Another way to go for people who are
thinking of
planting crape myrtles is the choice of powdery mildew resistant
varieties.
There are many varieties not susceptible to mildew.

Neem does work for fungal problems, but milk is as effective on powdery
mildew
and won't harm beneficial insects in the way.

I have a fungus on some of my Crepe Myrtles. I did last year and used a
product by Bayre that took care of it (a powder) that I cannot seem to
find
this year. Any suggestions on another product?

thanks
