See my post on page 1 of this thread. Also, the Mod's post on page 2 he lists "Sovran" which is also a good fungicide.
Done properly in veg, just before you flip, you will have no more worries for the balance of the grow.
Fuming (or burning) sulfur can kill mildew, but will not prevent a reoccurrence. Also, breathing fuming sulfer is more dangerous then most pesticides, and especially so for asthmatics.
Fungicides today are high tech. Some have one mode of action, the newer ones have 2 modes of actions.
Rally, Elite, Bayleton, Eagle, Pristine, Flint, Sovran and others are all good. They all work for 21 to 28 days, even if there are spores floating around, they cannot attach to the leaf or plant as the systemic action prevent the attachment in different ways for different products. That's why I usually rotate my products each grow.
