powdery mildew

Hi all, :D
           My baby bear pumpkin foliage has very quickly turned a white powdery colour & the leaves are curling up & withering. The pumpkins seem fine but are not yet ready to pick. Should I do anything to the foliage or not ??? Is this powdery mildew ??? It also has spread to my nearby peas which again are not ready to pick just yet (a late sowing). Any ideas anybody.

No expert  - can't say. But I do know that bicarb has kept in check (not cured) a very bad attack on my indoor cus. = Tim

Jak:
Excuse my ignorance, but how do you use Bicarb (Bicarbonate of Soda I presume?)? ???  I'm getting powdery mildew on my indoor cucumbers and don't want to spray with chemicals. :o

tim:
I guessed at 2tsp/litre, which gives pH8.5 - which seems a good figure!! = Tim

Jak:
Thanks Tim, I'll give 'em a spray tonight - I've got some bicarb in the cupboard. :)
