Hey guys I've noticed some powdery mildew on a couple outdoor plants that I have. Read all the info about how to get rid of it, or slow it down rather and wondering what you guys' thoughts are on the best solution. I've read about the vinegar method, baking soda method, neem oil, milk method and hydrogen peroxide method. I have all of these so any of them is not a problem but wondering if any one of them works better than the others.

I actually tried the milk method on one and it left a milk residue which i didn't like..

This is what I use for PM, it has worked well for me
  • 1 gallon of water
  • 1 tablespoon of baking soda
  • 1 tablespoon of vegetable oil
  • 1 tablespoon of dish-washing liquid
  • (or scale down to proportion)
Mix the ingredients together and add them to a spray bottle.

Spray your plants weekly, preferably on overcast days (or just before lights out) to prevent it from burning the foliage.

None of it works... It gets into the plant on a cellular level and CANNOT BE REMOVED PERIOD. You can wash the "fruiting bodies" of the p.m off where they mostly arent visible but the bottom line is prevention, prevention,prevention!! It never goes away or dies "because you cant see it" doesn't make it cured. Smoke it I would but you are smoking p.m spores and whatever the hell else they are made of. Theres lots of preventative measures and recipes to knock it back but just understand it isnt gone you just dont see it. Of course these are my opinions only but quite a bit of scientific fact also.

yea very very diluted mate like half a teaspoon to half a litre and wash it off after, it may leave a residue but even if it did it kills the mildew and is harmless

I won the war against PM a decade ago (discovered foolproof means of defeating PM, without exposing my grows/plants to fungicides/"poison"). Since then, I have encountered it inumerable times. Nearly every single clone/strain that I have taken in during strain hunting/hoarding has attempted to "Trojan Horse" a nasty PM into my grows, and every single time I've put that bitch in check.




Denial. "You" can wipe out the "roots" of PM on your plants, and "you" can completely eliminate all of the conidia (spores). You are the one in denial by stating PM cannot be completely "wiped out". That is "misinformation", perhaps you are intentionally trying to discourage inexperienced growers.

Old space = no PM in over 10 years.

New place. 1 bout and done. No PM since.

Filtering your incoming air is a key step in prevention. I have Zuccini - 20 yards from the grow door. It has the yearly PM starting right now. Been treating it since it started. Stopped and controlled at this point. Horsetail grass tea every week from here out. No problems in the building.

You are still wrong sorry guy... Prevention is key = no shit
No p.m for years = no shit if you know how to prevent its called exclusion and prevention. If your plant PLANT has it you are not eliminating it from THE PLANT PERIOD. There was no speak of environment if I recall ... Sorry buddy keep growing and continue with your denial:clap:

You halted its progress but you didnt cure it on that squash and you know it. Stop treating it and see what happens if its COMPLETELY gone then. Removed from inanimate objects yes , plants no...Its only visually gone. Something else you should also know

It can work....

I like 1:6 ratio of dried Horsetail to water......I add a tsp of green cure to break the surface tension of the water. green cure can work on it's own and dish soap or insecticide soap would work for the surface tension too. But 2 things that work together? Why not?

No, I am correct. I challenge you to prove me wrong. Link one peer reviewed paper/book/article that states Erysiphales PM is systemic and I would like you to name the portion of the PM fungus that traverses the plant systemically. Powdery mildew is not "systemic". You are asserting that it is. PM develops ON the plant and roots (hyphae) into the plant material. Kill the fungus, it's roots, and all spores, this is how you remove PM from your grow/plant (if it ever finds it's when in).



So, please elaborate on your "science" and prove me wrong.

:clap:

Look here my man, I truthfully do not care to continue this discussion. Im not backing out due to lack of knowledge or not being able to back up my thoughts/facts I simply do not see it your way nor do I care to. I hope you have an awesome harvest and stay P.M free.!! Due to your age and timeline you state you've been growing. I call bullshit on everything you say or think you know. Thats my proof and why I refuse to argue. Have a day.
