White powdery mildew, what do I do?

I treat every ten days with a fogger. 3-5 micron I rotate all the above. Once I get to flower I don’t spray anything unless necessary. This is a screen grab from treating. When it gets to the point I can’t see my plants treatment is over.

What are you fogging them with?

I made one with parts sourced from house of hydro. I got the 12xl.

We’ve all fucked up somehow and gotten a PM infestation. IDK anyone who’s been growing a while that hasn’t gotten it at some point, people far more talented and skilled than I. There are many ways to help prevent getting it, you aren’t wrong.

But if you do get it, it requires additional steps to actually eradicate. It can continue spreading in near zero humidity, perfect environment, filters, etc. Environment correction is just the foundation.

Ok… :roll_eyes:

What the hell does myclobutanil in conventional food crops have to do with spraying it on cannabis? Do you smoke food crops? Is Myclobutanil allowed in tobacco production? Do you have any credentials whatsoever to disagree with the scientists on the subject?

No… just your personal experience saying it’s ok to spray crap on your cannabis plants that NO ONE in the scientific community will say is ok to use. But somhow you know better than everyone else in the whole world b/c your so freaking smart. Why don’t you get off your high horse and get into the 21st century.

You sit and talk crap about how people continually have problems and organics don’t work, yada, yada, yada. But I grow thousands more plants than you in a commercial facility that is free of bugs and PM. The proof is in the pudding. So you can keep talking about how organic methods don’t work, it just makes you look foolish.

I can handle that.

It works overnight. IDK what to tell you man, I had serious PM I was having trouble with, then…poof. Eagle 20. And it was gone. I got it years later from running plants too close in higher humidity…break out the Eagle…poof. Lawn rust? Poof. PM on my outdoor tomatoes? Poof.

Michigan allows 200ppb myclo in Cannabis products…weird that no one has died.

How did you know it was totally eradicated overnight? You don’t. More of your ‘well it worked for me’. More unsubstantiated claims. I’m sure the personal digs will come next.

So if something doesn’t kill you, then it’s ok to smoke? :roll_eyes:

Only guy getting his jimmies rustled is you lol. I am not emotionally attached to pesticides the way you are with organics. I just use what works, fast. Just another tool to accomplish a task.

I can beat a nail in with a rock too eventually…but gosh I’d rather just use a hammer.

Apparently <200ppb is OK in Michigan haha. No one sick, no one dead. But it’s soooo deadly vernal.

Would it make you happy if I said: “I had awful PM that wouldn’t go away with hydro store organic treatment. I sprayed Eagle 20. Thereafter, it happened to completely go away on every plant for at least a couple years…the two events MAY be correlated”.

Or: “I had lawn rust. I sprayed PM fungicide. Lawn rust goes away. Probably a coincidence”

Or: “Tomatoes have PM. Spray fungicide that is listed for PM. PM goes away rest of season. Possible correlation”

Right, and myclobutanil is not allowed. That’s how bad it is.

only banned in these places Myclobutanil is banned in Canada, Colorado, Washington, Oregon, and Oklahoma for the production of medical and recreational marijuana

More of your nonsense.

Do you have any sources stating that myclobutanil might even remotely be ok for smoking? Any?

Do you have any sources stating that people might have been killed or sickened by trace myclobutanil in their ganja? Any?

Sky isn’t always falling, my dude.

My friend, he’s not even worthy. You can only toss a guy a lifeline so many times and have him push it away, then you chose to stand by while he dies.

I’m still awaiting your sources stating how safe it is.

Hundreds of patients exposed to myclobutanil and bifenazate through the recalls announced in December have come forward complaining of serious health issues, ranging from breathing problems to persistent headaches and nausea, blistering rashes and muscle pain. Health Minister Jane Philpott will not comment on the matter, despite several attempts to pose questions through her spokesman.

In Oklahoma, formal enforcement of the state’s testing regulations will go into effect July 1. Until then, as the program continues to get off the ground, lab testing is not required by the state. Elsewhere in the U.S., most states have banned myclobutanil as a chemical used in cannabis cultivation.

“What this is is a systemic pesticide, which means you can’t just wipe it off once it’s applied,” Hearding days. “What happens is this pesticide gets into the product and then, when heated, it creates these dangerous gases.” Myclobutanil’s fungicide properties work well against powdery mildew on face value, but the consequences of combustion are dangerous to humans; the chemical reaction continues to be studied.

Soon after the Oklahoma recall, the NCRMA kicked off a new educational video series focusing on these compliance issues. An upcoming video will zero in on myclobutanil specifically. “As pesticide recalls go, this is the one that is going to be referred to the most,” he says.

Hearding has worked directly with growers in Colorado who have dealt with myclobutanil problems. Once the chemical is used, any remediation is complicated.

“What happens with this pesticide, is it actually stays in the walls—in the plastics in your HVAC system,” he says. “I’ve known companies who’ve had to go in and scrub and scrape out HVAC systems for this specific chemical.”

What could happen in that situation is that nothing more than a flake of myclobutanil residue might have blown down onto a plant, which could then intake the tiny piece of chemical compounds.

One immediate piece of advice for any company facing potential contamination is to do a deep clean of the cultivation facility, something above and beyond any standard operating procedures (SOPs).

But a top U.S. toxicologist disputes that assessment, noting that “trace amount” isn’t a scientific term, and is often used subjectively to play down any problems. Minute levels of chemicals can have dangerous effects on the body, said Dr. Warren Porter, at the University of Wisconsin-Madison. Another expert told The Globe that levels above 1 ppm are not considered trace amounts.

Because myclobutanil is approved for use on some food crops, such as grapes, the medical marijuana companies involved in the recalls have told consumers it is not harmful. Toxicologists say those statements are misleading, since pesticides are designed to be metabolized by the digestive system. When smoked, they enter the bloodstream directly through the lungs without being broken down.

In fact, the effects of inhaling myclobutanil through smoking have never been studied and its manufacturer, Dow AgroSciences, said in January it has no intention to seek such approval for the product.

You are totally correct. I’m tired of The Poisoner making claims he can’t back up. I’m done on this topic until he can produce some evidence stating the safety of myclobutanil.

lol, don’t worry he’s got his personal anecdote: Well, I’m still alive!
He’s busy satirizing himself. It would be funny, except now I feel it’s actually sad.

what i posted was about cannabis only. And i understand . I have stated in other posts my methods, they dont include Eagle 20, but I also think there are so many things that are harmful to you …and not as worried as you perhaps.
