Help! Powdery mildew on my begonia!!

Quasar

Aww I have a huge Cane Begonia which is really tall and leafy. In the past few days I've noticed that the leaves had mouldy blotches and one of the cane stems was covered in white mouldy powder.

A friend told me that it's a fairly common disease called powdery mildew and can be cured. I have cut off all the sick leaves, and will keep the plant a bit on the dry side now, but is there anything I can spray it with?

Any advice will be gratefully received.

Wettable sulphur might be suitable - I know you can use it on roses but not sure about begonias.

Or it could be Botrytis - a big problem this year! I'd remove badly infected leaves and spray with a decent fungicide. More info from RHS here:

Thanks to both users for your replies. I have placed the begonia in a better ventilated position and will be looking for a suitable spray as soon as possible.
