As I mentioned, I've never had to fight mold myself - but the information below is either directly quoted (or paraphrased) from "The Best of Ask Ed" by Ed Rosenthal...
If your problem is NOT mold but something called powdery mildew then you fight it differently. Mold is normally grayish whereas powdery mildew spores are most often white.
If you are fighting powdery mildew, you can try any of the following safe (labeled for vegetable use) and non-toxic materials:
AQ10 (biofungicide containing ampelomyces quisaualis
Cinnamite - labeled for mites AND powdery mildew
Milk in a solution of 80% water and 20% skim milk kills it
Neem Oil (so yes Neem Oil should work if it is powdery mildew)
Plant Shield
Potassium Bicarbonate (brand names: Armicarb 100, KaliGreen, and Remedy)
Serenade - a product containing bacilus subtilis
Sodium bicarbonate (baking soda NOT powder)
The plant should be treated with one of these every 7-10 days. Treating plants AFTER symptoms appear is far less effective (sorry).
If you are just fighting mold and not powdery mildew then the best thing you can do is raise the temp to over 75 F and reduce the humidity 50-55%. If you see mold under these conditions that it is more likely you are fighting powdery mildew.
