Chris Jay Posted March 10, 2021 Share Posted March 10, 2021 (edited) I think we all having issues with powdery mildew at the moment, from Limpopo down to the western cape I have heard and seen. Guy showed me his plants yesterday, I actually want to record him saying sativa, its unique. He was so excited to show me his towering plants, and bang, it had powdery mildew all over the leaves, not trichomes. So strangely enough the day before another contact called me, saying I have someone you must meet, so went over and started chatting. Conferenced called into 3 other contacts talking about CBD oil ( blah ), cultivation ( cool ) , licensing ( blah ) and a new product that is especially fit for powdery mildew. So bottomline is wanted to ask what you guys use to combat powdery mildew, copper sulphate, hydrochloric acid , milk, good ol' Margret Roberts? Are you aware of the health implications of some of these products? How do you use it, when, during veg or flower? Would you consider trying a new product that could be launched soon and has multiple applications/benefits for hydroponics and water systems?

Fridge Posted March 10, 2021 Share Posted March 10, 2021 (edited) I use this as a preventative measure. So far it works. Edit:It's AQ-sf. A fungus that eats the powdery mildew fungus. Edited March 10, 2021 by Fridge 5 1 Quote Link to comment Share on other sites More sharing options...

Not selling anything, YETTTT. Market research cant be banned? Just asking about what solutions you guys have to WPM, something that is rife at the moment due to the tropical storms hitting our east coast. Thanks for sharing @Prom and @Fridge. 2 Quote Link to comment Share on other sites More sharing options...

This is what I've used and happy, and much safer in flower, and best to keep it in the fridge to keep the stuff fresh too. 1 1 2 Quote Link to comment Share on other sites More sharing options...

Thanks @StickyD420, I just try it the first time this season, as I had a battle with pm end of last season. It's comforting to see it helped you.

Plus as you are @Fridge best you store it in yourself as the bacteria lasts longer. 1 Quote Link to comment Share on other sites More sharing options...

PsyCLown Posted March 10, 2021 Share Posted March 10, 2021 I have been using aq sf for my grow and spray it as a preventative and so far so good. I also have some sulphur for just incase, but would prefer not to use it during flower, or at least only use it during early flower before the bud has formed. Milk works alright as a temporary solution, like if you get it late in flower - I'd be happy to spray milk to keep the PM at bay while the trichs mature so I can harvest. Would be keen to try some Seranade, but not available locally and have struggled to find stock overseas to import. @Chris Jay if the product works and works well, awesome. If it is safe to use during flower with little to no negative side effects, even better and has lots of potential for sure! 4 1 Quote Link to comment Share on other sites More sharing options...
Fridge Posted March 10, 2021 Share Posted March 10, 2021 By the way welcome back @StickyD420, you might not remember me as I got "upgraded" from fridgedoor to fridge. Always enjoyed your bud porn man. 2 Quote Link to comment Share on other sites More sharing options...

I do now, and thank you for the welcome brother, and compliment, always appreciated. @PsyCLown I agree with milk, and used it before, as a side note and precaution, please if you do use milk, use the low fat, so your buds dont get that sour milk / lactose smell we love haha. Unless you wash the buds afterwards 2 Quote Link to comment Share on other sites More sharing options...

Multiple uses, applications, bio degradable, safe to use, gluten free and organic kind of thing, but waiting to hear back from them geeks who sit in labs making chemicals. The cool thing is they are considering starting a cannabis brand. 2 Quote Link to comment Share on other sites More sharing options...
GreenGrow Garden Route Posted March 10, 2021 Share Posted March 10, 2021 I had some PM forming on my Pumpkin leaves and had nothing but peroxide.. I sprayed them twice with peroxide diluted with water.. 2- 3 times a day for 3 days and it's gone.. I'm sure someone on the forum spoke about it.. Have not tried it on my girls as I have not had it on them yet.. Is this a option..? 1 Quote Link to comment Share on other sites More sharing options...

And you can even pH your water and spray that, as it cant live on a certain pH, high or low. But the best is to prevent and not cure, as with wpm, most of the time when you see it, it has taken hold and inside the plants system, therefore m6ch harder to stop or fight. 1 Quote Link to comment Share on other sites More sharing options...
The_StonedTrooper Posted March 10, 2021 Share Posted March 10, 2021 You might find the peroxide adjustment to the water or even itself, is a low or high pH level and or the oxygen will stop it growing further, but like before it lives in and on the plant, it's on the leaves to spread and not to live as to speak, it lives off the plant. 1 Quote Link to comment Share on other sites More sharing options...

Bay Seeds Posted March 10, 2021 Share Posted March 10, 2021 Mildew gone in two days! You can't really get rid of mildew with a single application. Is hard to beat but easy to prevent. Don't immediately pick off the infected leaves. You need them to see if the treatment is working. Early in the morning, spray the plant down with peroxide and water mix ( 1 shot glass of peroxide with 1 L water) . Try to not let the soil get too soaked by this. A fine spray over the soil is enough. Try to not let any of the sprays run into the soil from this point on. I cover the pot of soil with a black bag. Wait 15 min and apply Baking powder and water spray ( 1 drop dish soap 1-liter water with 1 heaped tablespoon of baking powder. Try to not let this run into the soil. This will cause a sudden change of ph on the leaf surface. Wait 30 min or for the plant to dry completely. By this point, the sun should be out. Spray a 40% milk and water solution. The protein in the milk needs sunlight to work. After this dries you should see a noticeable reduction in mildew. It might even look gone. It's not. The next morning, spray the plant again with the peroxide and water mix at half strength. Apply Milk spray at noon. Clean water at dusk.The mildew colony should be dead by this point. Keep the sprays out of the soil and the plant will be ok. Good luck. 3 Quote Link to comment Share on other sites More sharing options...

Bicarb being a base though. Quote Link to comment Share on other sites More sharing options...

Chris Jay Posted March 16, 2021 Author Share Posted March 16, 2021 Also saw this post from @Futurama Hydroponicswith some products not mentioned above: Treatments such as the EcoBuz Disease Pro Preventative Bio-Fungicide are also a safe and natural treatment for fungal disease and are safe to use during flowering. We have also just got in the Buddi range of pest control sprays! 2 Quote Link to comment Share on other sites More sharing options...
