People will say it’s just the worst thing ever, but I simply don’t agree. Frankly not looking for another “but vernal pesticides r bad” argument from the peanut gallery.
I’ve sprayed in late flower before, just turned it into hash. Zero ill effects and lord did I smoke a lot of it. Look into it and make our own decisions about what to do about it. FWIW the organic remedies did nothing for me. Silica sprays discourage it from getting worse, more effective at creating high leaf surface pH than potassium bicarbonate, but it never actually goes away without serious intervention.
Well, if you keep saying crap like this, you’re going to get exactly that.
@rukus If you don’t care about your lungs or your health, I’d do what Ol’ Vern says. Otherwise, I’d take Craigson and OleReynard’s advise and get rid of that plant. There’s too much pm at that stage. It’s gonna get bad quick, especially if you are going to be having cooler temps.
Sorry it’s too late, but I followed somebody’s advice here on overgrow and used peroxide. 3 tablespoons in a half gallon. Pump sprayer. I’ve already read about better ideas and products here in this thread, but hydrogen is easy to find. I found it would work around 5 days to a week. In my case the p.m. didn’t get into the buds. Yours looks much worse. You don’t want to smoke that stuff. When I punched in powdery mildew here on overgrow, there was some advice somebody gave about washing harvested buds down and getting rid of all the p.m. with LAB . I would consider doing such a thing, but I think I would cook with it instead of smoke it. What do you guys think of that idea? Is it as unsafe as smoking it?
I think that is a really great way to battle PM, more resistant genetics. We have a couple of cultivars that serve as good indicator plants. If something is going to get pm, they are going to get it first.
I did hear someone say once if you want pm resistant plants, give the mother you are going to make seeds with a little pm and the offspring will be more resistant. I have no idea if that’s total stoner science or something to it?
its all over out side, we should talk to @JoeCrowe he has a bomb microscope. I do ipm , maybe not like that
one time its like a 3 way neem oil organacide or safer next time its Attak for pm cause its the most prevalent here per month
If I had a spare light i have clones we could infect one and not the other, let me think on this, would be 8 months before we had a preliminary idea though
some one here knows, does getting pm modify the plants dna or is it just like an infection, seems like JoeCrowe could tell us if its an infection by looking at pm then looking for it internally in the leaves or stalk?
had a saftey meeting and im so messed up anyways if that makes no sense just laugh
The powdery mildew is an external parasite it enters the plants stomata using haustorium. There is no germ part inside the plant, only a feeding tube that enters the epidermis. The stomata is an open pore for transpiration and the haustorium is a tube leading down the stomata and into an epidermal cell. I only had to spray my plants twice with sulfur to kill it off forever. If the organism was systemic it would be living inside the host, not on the leaf surface. The same mildew that preys on cannabis also preys on hops. Family: Cannabaceae
Hah hah feel free to look it up, I’d recommend reading several articles about PM the strange part is most of them have incorrect information/oldwives tales/broscience. Very few mention the host-parasite relationship developed over perhaps millions of years of evolution.
See what i tell you guys! thanks @JoeCrowe, one more question so can i take it that its safe to just wash it off? then smoke it as jorge C says to do? outa Luv
personally… life is too short to smoke contaminated weed. You could easily make edibles, nobody got hurt from ingesting mildew. The way I do it with the sulfur in veg you don’t need to worry about the sulfur or mildew. You can probably wash off the majority of the mildew but that’s gross. umm but if you are using closed loop resin extraction with color filter mildew isn’t a problem - heh heh I say that in jest - nobody is doing that shit here.
same here for both of you. thanks again, I wont smoke it , I was in a fire and and one of the side things to that was my lungs, just wanted solid advice! thanks again
heh heh yah I suppose the bottom line is mildew isn’t soluble in BHO, ISO, ethyl alcohol or solvents of that type. As long as you are filtering it, there shouldn’t be any contamination, you don’t need a fancy closed loop system to enjoy those benefits.
Thanks again but something you did say made me wonder ,
So its all over outside primarily on the grass, but saw it on a broadleaf weed as well. is that a species i need to worry about with my cannabis plants? or no
