Powdery mildew - An easily exterminated parasite

@JoeCrowe what is the minimum amount of time the sulpher has to be in contact with the pm for it to be effective?

Those mildew strains can’t infest cannabis, so you’re ok. It’s highly host specific and only infests a plant that seems to send out a compatible signal. I’m not talking magical signals, but the same RNA signal system that all fungus uses. According to latest observations lol! I’m sure it’ll pan out when I check it again.
I would say when the sulfur dries up, the mildew is toast. I don’t think you can wash the sulfur off easily after it dries on there. I did time the destruction of the colony and it seems to dissolve the fungus on contact. I should gather more data on the timing of the parasites death, and make another lovely snuff film! It can be tricky to really tell when the parasite actually perishes VS it looks dead to me.

@JoeCrowe Thanks for the reply. I have watched your videos and really appreciate all you do except now I want a microscope :blush:

I think it was the most valuable tool I have ever purchased. Biological research microscope! Now paired with the usb 3 camera and the computer for image processing. Amazing shit. It’s not top of the line, but you can get in some serious observations and mod that shit up when times change.
Science gets you to the top and keeps you there. It’s just another tool of the human mind!
So many observations to make. You don’t need to be a phd to solve riddles. Once I’ve made enough observations it paints a picture for me. Patience is a virtue, a good study can cost you 5 years. I like to pack 'em in dense so in 5 years I can complete 5 different studies. Helps the throughput. lol!

I totally agree with you. Soon I will ask for your recommendations on these tools of the trade and hopefully be able to contribute to your studies. Much love @JoeCrowe

What has to be done is put the light on a timer every few days for 10 minutes in a small room/tent of 4’ x 3’ with the exhaust off and the fans on reaching the whole room. Then put the exhaust on after about 30 minutes only. And don’t go in the room until the metallic smell is gone. Ozone can screw your lungs. So what you you would be doing is get the Ozone to a level that kills the PM but not the plant. You start low as far as time on of the light and increase until you damage the leaves a bit then back off to half of that. And you can space the treatments out after a few. This really works but Ozone is dangerous and should not be exhausted into a closed space/house.

Sulfur works for you. I get my air from outside and I’m next to the Great Lakes, so I get a blast of PM every year in the spring and a bit in fall. But I’m automatically killing it and barely ever see unless humidity goes through the roof when I’m drawing pm in. But it works for me.

oh damn, those are old wives tales about mildew. It’s not blowing in the wind and it’s not everywhere.

i posted this somewhere else but this is where i should ask the question

i have some indoor females that i’m about to pollinate with a flowering male that’s outside that has powdery mildew, so if i collect the pollen from it, i’m pretty sure some PM is also going to get collected and going to contaminate the females i’m trying to pollinate, right?

should i try eradicating it with sulfur or just not do the pollination?

eradicate! One good spray then you should have killed it off in one go. Then you can feel free to pollinate with wild abandon.

Depends where you live and the air you input. I live a half mile from billions and billions of gallons of water. If I put a dehumidifier in my outdoor rooms I could treat with sulfur twice a year.

The humidity has nothing to do with the powdery mildew. The lake has nothing to do with it either. It’s an obligate biotrophic ascomycete that lives only on the plant and plant tissue. It’s not blowing in the wind or on your shoes. There is a single requirement for it to replicate and that is the host plant is alive. I submit to you that your ultra violet light is nothing more than superstition, and does nothing to powdery mildew.

I don’t need to argue, I find PM on plants in my neighborhood in shady spots. Do you want to come to my neighborhood and become an expert that I need to cure mildew that doesn’t exist. We also have more spiders than you could imagine because of the lake and they supposedly can spread spores also. The wind spreads PM spores. The research has been done. If you want to argue then find another person. If you want to teach me something, I must have a need. I have no issue with PM. But you probably know the sulfur process great.

well good luck with your old wives tales and magic dancing. I wish you could realize you are believing in bro science, but so be it. If you want to learn some shit, I’ll be here. I’m some kind of high level cannabis mentor. shrugs

I don’t doubt what you know about a complex subject like growing Cannabis. But you need to learn more about PM as it does travel by the wind from plant to plant. It was proven by research at an East Coast University, look it up in white papers. And you definitely need to learn to be less argumentative. I’m just a person.

Don’t you dare challenge the expertise of a high level cannabis mentor.

What you suggest as a treatment has already been debunked. If I let people think what you said is correct, they would be lost. That treatment will fail like all the rest of them and waste people’s time and money.

Hey did I see you at the competition? I think I saved your grow by teaching you about mildew lol!

If it’s the competition I’m thinking of you win by a mile.

And no. You did not.

hah hah shit, you should have showed up, we could have raised you into a champion. That’s what we do up there at the unicorn. Hatch 'em out.
