The crepe myrtle is dropping leaves. The leaves are curled and dried on the edges. I have about 25 crepes and they are all doing it. Is it a fungus? How do I treat?

I suspect you have a pest infestation, likely aphids. Treat the trees with neem oil (often sold as fruit tree spray in the stores - check the labels). It will treat for both aphids and fungus and is safe for people and pets.
