Sulphur and Stylet Oil will only work against Powdery. I do not know about Fungastop.

It is a lot easier to go "Organic" in certain areas. For example a grower in a hot semi arid climate could go that route a WHOLE lot easier than a grower in the Midwest or Eastern US.

Most of us growers would love to go "Organic" - especially if the products were there and cheaper - but so far it is only a dream.

Sulfur and Stylet Oil are both organic and both will control fungus on
vinifera. Fungastop is organic and I've seen tests that show it will
control fungus on vinifera. There are plenty of other options out there
as well. There are lots of organic vinifera wines on the market, and
I'm sure all of those growers see fungus problems and somehow overcome
them.
