I wouldn’t want to bet on that.
New studies show it is.
Any beans off these plants I sure wouldn’t crack.
I keep a pretty good eye out for what I collect these days, people with pm or mites, I dont touch their wares
Mites and pm pretty much hand in hand.
new studies I suppose they have evidence?
your claim is mites and powdery mildew you can’t get rid of?
I have extincted powdery mildew and spider mites. It’s incredibly easy.
I’ll believe it when I see, they’ll be back.
Use your device and look it up in the net, like I did.
Good Lord gave ya hands and fingers and something up top to reason with.
ok it’s been over 20 years since I got rid of the mildew. And it’s been over 5 years since I protocol 0-ed the mites. When do I expect them back?
I came from a far more advanced club.
We’ve were up down sideways all around
ok, so that counts as evidence, an argument from authority? Sorry, authorities don’t exist.
yes they do they’re called botanists, county extension officers.
ok so where are these botanists because I have something to teach them.
I’d like to see some of those studies. The info I have seen says it is not. I sure don’t know the answer, but I’m open to new info on the subject. 
you just keep believing that cuz i sure in hell dont believe you.
Later on
strange just looked it up not to long ago.
Internet is a pretty big place. Any clues where I might find such info? Again, not arguing, just trying to learn.
gaaa you don’t have to believe me! I never demanded that. Only need falsification! Things don’t work because you “believe” in them.
ok well, demands for evidence are kryponite to unsubstantiated claims. Feel free to check out my protocol 0 thread or cannabis microscopy.
I have anecdotal evidence that powdery mildew is caused by ghosts.
I think there needs to be more testing done on cannabis specific types of PM. If that info is out there, someone please post it up. Here’s a couple of tidbits. Not gonna spend too much time on this.

Unlike most fungal pathogens, powdery mildew fungi tend to grow superficially, or epiphytically, on plant surfaces. (2) The classic white powdery infestation occurs on the plant surface, and the mycelium invades the leaf one cell deep (Jessica Cortell PhD). Non systemic fungal pathogens live in or on a host, and form localised lesions. They can’t grow away from the site of infection. (3)

From Clemson University:
In spring, as daytime temperatures rise above 60 °F, the fungi responsible for powdery mildew begin to produce spores (conidia) which are dispersed into the air. Infections occur when they contact a suitable host and environmental conditions are favorable. Initial symptoms are small, circular, powdery, white spots which expand and eventually join as infections progress. Infections spread as spores produced in these white patches move by wind and splashing rain to other locations on the plant or nearby plants.
The fungus survives the winter attached to plant parts and plant debris such as fallen leaves. As weather warms in spring, the process begins again.
Humidity is an important factor related to the onset and spread of powdery mildew. Unlike most fungi, these do not require free water to germinate; only high levels of relative humidity. High relative humidity favors spore formation, and low relative humidity favors spore dispersal, which explains why powdery mildew tends to be a problem when the days are cool and the nights are humid. Temperature is also a factor. Although powdery mildew can occur all season long, it is less common during the heat of the summer.
Ya from my sadly extensive experience with pm, and from everything I’ve read, I don’t think it’s systemic. I definitely don’t think it can be transmitted via seeds.
Is there some evidence it IS transmitted by seed? Scary thought! I have to share something I noticed about PM. Last summer,2019, I had a plant pop up wild, from the previous year. Gorgeous plant. No PM, though it grew feet away from zucchini, which had it badly. (Same PM?)
I cloned this plant and neglected the rooted clones indoors over the winter, where they developed PM, though not badly at first. I placed them outdoors, where the PM got worse and worse, infecting this years crop as well, which was nearby. So I decided to kill the clones, and they went into a dark corner of the woods about 50 -75 feet from my plants from this year, where I forgot about them. The PM battle continued awhile with this years crop, and got so bad at one point I went to look at the dead PM infected clones to make sure they were dead. They weren’t dead. A month with no water and they lived, rooted into the ground slightly now through the grow bag. At this point, I felt the universe wanted me to keep them there to test everything else I grew this summer, which I did.
Here’s the crazy part. I looked at the clones again a few weeks ago. Every part of the older growth that had formed early on was destroyed by PM. ALL of it. Dead. BUT, and here’s the kicker, the portion that grew AFTER being rooted into the local soil, was PM free. None. Some connection the roots get from contact with the local microbes in the soil must have given the plant immunity to the PM. Incredible! More experiments are needed, but the best prevention is a healthy immune system beefed up with local microlife from local soil. The way nature intended.
That’s pretty cool Upstate! I had a similar story with hostas surviving a midwest winter in a lawn bag and growing the next spring.
One thing I have noticed is when plants are kept in proper vpd, they are far more resistant to pm. I had heard different stories about pm being on seeds, but I don’t know if it’s true or not.
Could the PM be ON the seed and not in it? Causing exposure to it right from birth…hmmmm…
Tough hostas. Like a mini greenhouse, really.
