Can you please identify the disease on this young Hass Avocado tree and suggested treatment methods?

As far as I can tell this problem developed very quickly in approximately one week’s time. When I touch the white material on the leaves, it rubs off in powder form. Thanks for any help you can off.

It is probably powdery mildew, a fungal disease.
