PM is not systemic to the plants, but rather the room that they are grown in.
There was a man on a farm who once said..
If you ever come across another Cannabis consultant who talks more about genetics and yield rather than cleaning protocols your in trouble.
I'm stealing that

why dont ppl run a sulfer burner? works for me everytime IS there a problem that I am unaware of with sulfer burners?
Smells like a poopoo?
If you want to decrease Pm infections Amino Acids and silica supplements help.
B Vitamins help prevent PM as well with that equation there
Nope. Pm is systemic, unfortunately. The rooms we grow in can also harbor the fungal spores but thats what Physan 20 and/or bleach douches are for.

Dude PM spreads through spores, not plant tissue. People need to stop spreading this misinformation.

Misinformation or information you have yet to research yourself?
"While most powdery mildew fungi produce epiphytic mycelium, a few genera produce hyphae that are within the leaf tissue; this is known as endophytic growth."
The above excerpt is from an article on The American Phytopathological Society website and written by Heffer, V., M.L. Powelson, K.B. Johnson, and N. Shishkoff. Oregon State University and USDA-ARS http://www.apsnet.org/edcenter/intropp/LabExercises/Pages/PowderyMildew.aspx
"An endophyte is an endosymbiont, often a bacterium or fungus, that lives within a plant for at least part of its life without causing apparent disease."
Endophytic fungus defined:http://en.wikipedia.org/wiki/Endophyte
My closing thoughts:
Powdery Mildew is a generic term for the legions of different species of fungus known to cause the common white powder on leaf surfaces. Some of those species are Endophytic and will lie dormant in plant tissue without noticeable signs of infection. So in part, you're right. There are powdery mildew infections that exist epiphytically and can be killed without the use of systemic fungicides. But then there are Endophytic species of fungus that DO exist systemically. Which one you have is a good question; but I doubt commercial grape vineyards waste their time sending infected samples into a pathology lab for identification- they use systemic fungicides for SYSTEMICALLY existing fungus.
