I've been shopping around trying to find the best protection for my
grapevines since disease (mostly powdery mildew) is very common in our area.
I found Lime sulphur solution and sulphur powder. I tried to get as much
info on each but unfortunately for me most of the people working in the
local nurseries are 16-18 year old students that don't have a clue

(
So does anyone know the difference in these two products? One says not to
use on Marechal Foch which is almost 50% of my grapevines. Help!
