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. Email email@example.com

It is probably powdery mildew, a fungal disease.
