It looks like a fungal disease, but to get an accurate ID and form of control I would send samples of infected leaves to to the diagnostic lab affiliated with your county Cooperative Extension Service. Google county cooperative extension service offices in Nevada for contact information. Best And Happy Yardening, Nancy.
