   Can anyone identify this white powder?
   It's not dust...
   
   I had eight spartan apple seedlings growing outside in cups and it affected all of them at once.
   They are still making new leaves. It takes about a week for the white powder to spread to the new leaves.
   Is it a fungus?

   I think so -- perhaps this: Powdery mildew of apple and pear | Integrated Pest Management Program
