All you can do is treat the problem as it occures!
Baking soda works well, a teaspoon to a litre of water with a drop or two of dish soap, helps to keep the mold damage to a minimum. You will need to spray either in the early morning, or late evening, then again after every rain.
Mulching the soil acts as a barrier to help reduce the occurances. Rain hits the bare soil, which has spores on it, and splashes the spores up onto the leaf surface..... it can be a nasty cycle!
The spore also move through the air and settle on the foliage.
If you want something heavy duty, then you can use Neem, which is a safe to handle and use spray!
Remember not to wet the foliage when you water, soak the soil instead. Wet foliage is a perfect place for the spores to propagate!
