h2o2 foliar application for powdery mildew?

fellas,

stumbled upon Jorge Cervantes powdery mildew removal using h202 on cut flowers.. which lead me into users using h202 foliar to control powdery mildew during flower.

after much research i ended up being lost and confused with users stating different mixing ratios and most of these posts were made years back and none to be recent.

Anyone successfully used this method to control PM? And if so what mixing protocol do you use..

thanks in advance..:thank you:

then seal your room.. or filter your intake better.. you shouldnt get pm unless you introduce spores.. = negative pressure.. or your not running enough OSC. Fans in your setup.. need to have your leaves moving man.. prevents this bullshit..

not sure if ortho's Volck oil is still available but it does a very good job with Pm.
bonnide offers it too.
it's a refined mineral oil thats great for other rusts, fungus and a multitude of insects like spider mites leaf miners white fly, and many others
AND
it has ovacidal properties to wipe out eggzzz

btw
it's very low in toxicity compared to other PM treatments

and all in 1 bottle

You dilute 35% h202 to 10%...

SOAK your plants and then immediately dry the plant in front of fan...

PM gone...

Hey there, I dont think "control" is the right word, but you can definitely help "prevent" PM with foliar sprays. Whoever said sodium bicarbonate is on the right track, even straight tap if your pH is high (>7.8)just get the pH of your spray up, thats what will help the most. Higher leaf surface pH can totally help prevent PM. I wouldnt spray in flower.

forget spraying them, air flow is key! I can flower plants at upto 89% RH at night with good airflow and develope zero mold...

In outdoor environments air circulation is constant even with little or no wind . hot climates tend to be affected with high RH levels at night tho you can grow plants with no mold successfully..

Going back to an indoor setup during the light on cycle RH tents to be low.
this can be rather similar to outdoor levels of RH during the day .

this concludes that Mold is merely a air circlation or filtration problem not necessary the levels of Relative Humidity witch is usually prioritised .

what is fresh air? fresh air can be created in sealed rooms outside air is not important ... i use 100% sealed rooms with night RH levels of sometimes maybe 95% with no mold

one thing i have learnt is that there is some mold resistant strains anyway
