Which plants are you talking about specifically? I might have something like that around here. Peas? I didn’t try it on those, just the wood aven.
I got some comparison photos! Even the wood aven colony didn’t like the couple drops of sulfur water. Crazy days!
All our plants, lol! I have to spray a homemade deeroff on everything outside. Not pot… flowers, veggies, and shrubs. The spray just beads and runs off if I don’t add a spreader/sticker. Rain just seems to run right off, too.
Yah there’s lots of plants water can bounce off of. Cabbages, broccoli etc snow berries. Water definitely spreads out over cannabis leaves, that’s for sure! Here’s the protocol I used in case you want to try it.
I took the leaf and put it on glass, then I added more and more drops of water until the whole thing was in a puddle. It seemed to create like an envelope over the leaf that I could drop sulfur water onto and have it spread out like mad in the video. I think they manufacture sulfur with spreading and wetting agents for use on hydrophobic plants. I’m just using the DIY method of submerging it lol!
wow at the contest, that knowledge on powdery mildew really paid off. I went over to the dab bus where people were having lunch and sat down. I was chatting lightly with this group when one said the mildew took over their operation. I said shit man, you are in luck! I studied that parasite hard and here’s how you kill it off. 1 tbsp of 90% sulfur mixed with water and sprayed on the plant. Twice, two weeks apart and don’t use on something you sprayed with an oil based product. BAM! The grow saver! Said he was using fulvic acid on the mildew. faaaail! Said he heard the parasite was inside the plant, you can’t get rid of it. I said according to high speed microscopic images, the sulfur dissolves it on contact and it never comes back.
He had to repeat that. “You’re telling me, I spray my plants with sulfur and the mildew dies and never comes back?” “Precisely, my friend.”
I also found another colony! ooo this plant doesn’t need wetting agent to get wet, so it’s a perfect victim! I should look up the name of the plant heh heh.
You can see the claim that hydrogen peroxide will eradicate powdery mildew. Oh… fact checkers said that’s false? Hilarious shit, they tell you to read an actual study.
Colony took a serious hit to the dome from being dried out. You think that shit is still viable some how? Ohhh… me so curious! fuuuck! I know I’ll regret this later but fuck it I have other experiments to perform. I can circle back… when I really fall into regret mode for not testing it
Hay Joe! About a month after the 2nd treatment on my veggers, I sent out cuts from them… with full disclosure. I still haven’t seen a colony, or have heard any reports of PM from any of the recipients. I’m still impressed
I think you took my advice the furthest, with the eradication of the parasite in your garden as well. With that maneuver, you have defeated phd scientists in agriculture. You have definitely become a powdery mildew assassin! lol! Write a book about eradicating powdery mildew, it’ll be a single page long and people will be like fuck you made it all up bro.
lol! You should start growing acid loving plants. I burn through that sulfur, using it to balance the PH for my blueberries. You could grow cranberries or Hydrangeas. All sorts of radical crap can be grown using sulfur, if you want to get your feet wet…or sulfur-ey as the case may be. Those kinds of radical plants are what people have difficulty growing unless the ph is already spot on.
Poor sucker down the road planted hundreds of blueberry plants… and got woody debris out of the forest to balance his ph. He doesn’t know it, but those plants will be dying by next year without radical intervention. The part I’m curious about as always is his mind. Can he understand he believes in old wives tales? oooo! I love it.
Oh my! Those are preliminary results, but I swear to fuuuuuuuck the thing is responding to only the correct plant signal. It looks like they never hatched! A picture is worth a thousand words eh? lol! In this case I have to explain what the outer space photo is. The pill shaped parts of the mildew are supposed to hatch open and spit out the spores on to the leaf where the fungus invades the pore of the plant and starts to grow on the surface. In this case, I rubbed the mildew on a host it is unable to infest. I think at this point I tip my hat to the evolution of this parasite. So efficient! wow, talk about not breaking the mold. bah hah hah! Like every other fungus it seems to get some kind of signal from it’s host. Amazeballs. I think that might be something nobody else knows. Keep it under your hat eh? Could be worth a fortune
I’ve had success with a UVC light as it generates Ozone. It only partially damages the cannabis plant but kills White Mold in the whole grow space. I used Ozone as a technician a lot in my career so warning is it’s very dangerous to those that don’t know the smell. But it works great and I have a fresh introduction of mold every year into my semi outdoor growspace. So my growspace is the perfect lab to test mold cures.
I’ve got a 36w CleanLight Pro. Not sure if it generates ozone, but I hope not. That’s not good to be around, is it? The UV-c does damage plants, especially if it gets too close for too long.
The UV-c only kills the pm if it strikes it directly, and that’s pretty hard to do without getting it right in the branches. Plus, I had to use it everyday, or pm would reappear within a week, sometimes less.
2 sprays of sulfur, 2 weeks apart, and I haven’t seen a trace of pm for going on 6 months. That was after fighting with it for almost 3 years. I could control it, but not eradicate it.
The CleanLight’s going back on ebay, where I got it, lol!
Been clean of that whore known as PM for quite some time but despite LABS serum sprays and a couple IPM sulpher treatments she has reared her ugly head once more.My plants went into flower a week and a half early this year and I’m too far in for sulpher treatments.
I have been using a product called Cease which I should have bought springtime and treated the area now I think about it.I found two possible culprit vectors a peony my wife had up front that was covered in the shit and one whitemans footprint plant that looked like it was frosted in pm like a cake.Have removed all effected leaves and am currently treating with Cease and Plant probiotics spray .So far holding the fort down but I will have to restart my indoor stock and do a total sterilization I have my Texada Timewarp that is being treated and under lockdown till I can get my Timewarp seeds started and I see if I can get her in a similar seed form then I’m axing that clone and starting form seed stock again and after that no more cuttings from the outside world again just for precaution.I fight humidity from living next to a Great Lake.Will be making a shit ton of JADAM sulpher for next year and I’m going to treat the entire area.I have not found one strain that can withstand the PM here the shit is nuclear.
oo! Definitely look around to see if you can find the host. Did you bring in any other plant material? Usually the host has to be within 6 meters or 20 feet of your grow. Even bringing in plant material to dry can infest your crops. If you create a “scorched earth” where you spray all mildew harboring plants within a 6 meter radius, it should be killed off. Best performed in the spring to nip it in the bud, but you can do it any time.
@CapnCannabis I sprayed an indoor grow plagued with pm that was about 10 days into flower. I had some pistil burn but the crop was saved.
I too live in Michigan and have just recently seen it on my zucchini and butternut squash which reside well within the 20 feet zone Joe Crow mentions of my outdoor plants. So needless to say I am concerned. Haven’t seen any on the cannabis yet but I am gonna fog them with sulpher regardless. Not taking any chances.
