White powdery mildew, what do I do?

Why do you think grape growers have such a hardtime.

I can vouch for that it’s all I run is perpetual, still to this day in fact just not on a bigger scale like I was.

I can attest to this. I did this in wk 7 of flower and rode it out through flush until harvest and still had to wash my buds to be safe. Sucked. Really mutes the terps…

I would still highly recommend staying away from eagle20, propiconazole and all the other fungicides made for ornamental use only. These are not good for your health and are really not needed. If you are continually getting PM two things, 1. Like Joe said, you have to clean the space and disinfect. Sulfur is hands down the best option in my experience. 2. You have an environment that is conducive to PM.

There is some really good information in this podcast.

we are not talking about grape growers. Powdery mildew is biotrophic.

Spores don’t exist, apparently. But someone just learned the word biotrophic haha.

@PlantShepherd you will be pleased to know myclobutanil is used on food crops, fruit trees and the like, not just ornamentals. Propiconazole is used in food crops.

Ketoconazole, a drug in the same triazole fungicide class, is in some dandruff shampoo…pretty sure I’m gonna live. Works like a charm too.

I know hundreds of people who have tried to eradicate it when conditions are favorable it does come back.
It maybe a month or two but it does come back.

Takes a bit to become a full-blown epidemic that’s why people think it’s gone.
Till you wake up one morning and wallah guess what, I’m here.

No one’s arguing here, don’t know where you get that.
Just a simple discussion with disagreements.
You believe what you need to believe, ill keep traveling on what I know.

here’s the problem though, your disinformation is not helping people get rid of their infestation. I got rid of the mildew that way and so did many of my clients. I’m not sure why you keep insisting on what you say, even thought you have already said you can’t get rid of the mildew. I can get rid of the mildew and I did. I can image the mildew at a microscopic level and actually see… infestations.
@Vernal, you are not even worthy, you proved yourself to not even be my peer when you didn’t read the mildew study. It made me sad. Please… seek education.

@JoeCrowe It’s not disinformation, he just said sulfur didn’t work for him. It’s an old old remedy, it controls, but it doesn’t eradicate. Wonder why so many farmers around the world struggle with mildew when literally everyone has access to cheap available sulfur. Almost like it isn’t a one shot cure-all people such as yourself claim it is.

If you’d like to vent your frustrations, you can draw a crude cartoon about it. Art therapy is good for the addled and those with delusions of grandeur.

see, your response is completely devoid of actual help or information that people can use, congrats.

A stinging retort lol. However will I carry on with my day?

Surely you must agree that plenty of other people are using sulfur to control their mildew…with some people spraying it a dozen times throughout the season.

How do you explain all the people using sulfur and continually having issues? It is cheap and available in every hardware store and garden center. I know many people who have tried sulfur, and it seemed to help for a while…then came right back. What happened, where did they all go wrong? Large facilities use sulfur burners frequently…and it keeps coming back.

I have done experiments with bleach. A spray at 10:1 will eliminate powdery mildew for a week. Then it comes back. So you’d need to spray every week just to maintain.

Bleach breaks down very quickly. Into what, I dunno.

I smoked it and didn’t die. Neither did Mrs Foreigner. You could also rinse the buds if it suits you. The bubble making process would rinse it all away.

I would consider doing it again if I was two weeks from harvest.

Not everyone is lucky enough to be a genius with a clean room.

How did they get it to begin with?

I mean is it not possible the sulfur worked but it was brought in again?

The very act of acquiring it through means other than infected clones means your sanitary conditions are not up to snuff. So its also likely it can be brought back in.

Its like letting a fly in…killing the fly and finding another two weeks later and assuming the dead fly wasnt really dead.

At least this is what im banking on. PM isnt some instoppable scourge that conjours out of nowhere and never goes away. Its comes in from outside. Whether on your clothes, hands, shoes. Whatever. It comes in. So its reasonable to assume it can come in again.

If joe got his from a clone. Thats his point of infection. Doesnt mean its not outside or hes an some clean room type grow room. Just means hes been lucky enough to avoid bringing. I think that has a better chance of removal.

You can read all the studies you want, there is no definitive answer.
Been looking at studies for over 5 years, keep studying my boy.

You’re putting high hopes in people’s heads.

And @vernal Wow first time we’ve agreed on something.

I think we can all agree on each garden is different. And each persons throroughness is different. This is science. The most of us are lazy stoners.

I believe joe and the rest of you. Who am i to tell you what you see and know. Im not god.

For me and my situation fearing pesticides and this being a hobby it was sensible to shut down for a bit. Cull every plant. And clean my house in the process.

Is there away to completely eradicate this shit, highly doubtful.

Everything has been tried but something somewhere will work.
Could be as simple as pissing on it or as complex as rocket science.
Just hadn’t been adopted yet.

And for the rest on here stop taking in clones, use plenty of air and change your clothes from outside to in.
