white fungus on nectarine tree

i have some white fungus or powder substance forming on my nectarine tree. went to osh, and an employee said it is the watering, and i have altered my watering patterns, but it is still there. any ideas what it could be? i am located around the bay area in california, but not near the coast.

thank you

Powdery mildew? ([url=https://www.clemson.edu/extension/hgic/graphics/2003/dogwood_powdery_mildew.jpg]Image[/url], [url=https://z.about.com/w/experts/Plant-Diseases-715/2009/03/powedery-mildew-citrus.jpg]image[/url])

If that's what it is, you might be able to control it by spraying with a mixture of milk and water. You can do a search and find several discussions about it on the various forums. :)
