So far I've had little mildew in my garden area probably because its so open.  
Mostly its on all the plants in the cooler, damp areas in what I would call 
riparian areas.  It happens lightly every year.  I finally figured out this year 
that it is for sure powdery mildew because its beens so much cooler and 
damper than usual that is been growing more heavily.  I used to think it was 
just dust that settled on the plants during the day and "pooled" in the dew at 
night.  The leaves all look like a dusty car after dew dries in the morning. 

Perhaps your getting pm with the bindweed because the bindweed slows the air 
circulation around your plants.
