Powdery mildew question?...Hmm

[Dr_love]

Ok so I just found some powdery mildew on one of my bitches (shes still vegging)
I mixed some PH UP and some water together and applied it to the infected plant just now. But I was wondering if I should isolate the dirty bitch, kill her, or put her back with the others and foliar spray the crop with baking soda and water, or PH UP and water?
I know I should probably construct a sulfer burner, but I am flat broke tell next month.
Also, I took some clones off her already, should I toss those, or will they be alright?

I'd stop calling her bitch... she probably doesn't like it. My girls never respond well to this... they like 80's music though.

The pH up will be ineffective though the baking soda will help. You can spray, or better yet, wipe with a light alcohol solution and/or h2o2. Especially wipe if isolated to a few leaves. The baking soda will only temporarily prevent further spreading, so you can dip the cuttings as well. Repeat every 3-4 days or so.

The primary, root problem is high humidity and/or lack of air exchange. If you address those issues, the pm will disappear & certainly not spread. Best.

Walmart has a 3-in-1 spray for PM, spider mites, and fungus. It's made by Safer (im pretty sure) and is only $6. I had PM on my clones when I first got them and a few sprays took care of it...totally gone.

I had PM in a greenhouse in the Desert-- I got the Humidity down in the single digits, sprayed with Neem, Baking Soda, and some other shit Home Depot sells...
But it just progressed--
I find that some strains/phenos are just more prone to it--
Do the best you can--

A lil Mycostop never hurt. It may be too late for what you have growing but if used when they are clones or seedlings, it can help immensely with PM.

I have this issue currently with a couple going. SO far I have tested these

1. milk/water sprayed on the affected areas
2. High PH water sprayed on the affected areas

next will be the h2o2 mix and will be wiping the leaves and affected stems and see what that does.

I think the milk solution worked because that one definitely made a ton of the issues disappear BUT not completely.

Odds are a solution actually made for PM will be the best idea for sure. I think you should go that route, I am just wanting to test out all the "Home Remedies" that I keep reading about on here and see how they do.

I think I will just end up getting something already bottled up and proven to KILL PM completely without leaving residue or affect my organic growing style in any fashion as far as chemicals go.

I have for the first time a bad outbreak of PM, I believe its because of all the rain we've had lately here on the eastcoast. I run a closed system with an A/C, Dehumidifier and two 18" oscillating fans blowing 24/7 and I've been growing for 6 years and this the first time I have ever had anything like this, the plants look like they've been dusted with powdered sugar. I'm going to have to chop the worst affected ones, I don't think they're salvagable.

Good luck.

well i used to live in oregon were it seems to never stop raining and i run a room similar to what you do as do my brother and a few other buddies and they all still presentlly live in oregon and still use these bags you get from a hardware store thay're kinda made from the same stuff as them anti static bags that computer HD's n what not are packaged in they work really well theres something in them that traps the water in the air into these bags then it solidifies into this kinda salt like crystal i cant remeber the name of them off the top of my head but i can tell my brothers first grow was in an old almost falling down dry rotted shed out back in the middle of winter around a town named sandy oregon on the westerly slope of mount hood so ya real humid and he ran the bags and had to run a heater as well but i think these bags might be of good help now your mold or mildew or whatever problem im sorry man i got no ideas lol at the moment i live in vegas and uh ya its a desert out here

i would like to know what solutions in % to go for when mixed with water and putting in baking soda ( bought 2 jars of it), alcohol or/and h2o2

i had some PM in my green house as its hard to keep proper ventilation there and because i got apr 1300 plants crammed i there atm

also im going to transplant most of them into corn fields now

will PM disappear from them when they go out in fields with good winds and all day sun?

Go to Home Depot and they have a greeen bottle (can't remember the name) but it is by Safers. There is a yellow fungiside bottle which is yellow and has too much sulphur in it so it will burn the leaves. The green bottle is safe to spray the crap out of her. Do this twice in a two week period and it will kill it so it won't come back. I use it all the time. The onlg]y time you want to not use it is when you are after two weeks into bud. Sulphur in the lungs is not a good thing. The PM will still look like its there when it dries up but it will just be like a white color and not spore like anymore. Don't worrry, its easy to clear up but do it is soon as possible.\

i have found what works best for me is 20ml/gal of zone plus penetrator and then i foliar spray the plants. you should do this every other day for the first two weeks

bumb

i need to start spraying very soon against powdery mildew

i dont need greencure or links to places that sells stuff i cant afford these days or would take way to long to ship

but if any one actually knows how much baking soda to use for each liter of water, apr 1/4 gallon, i would really appreciate it

Baking soda makes an inexpensive control for powdery mildew on plants. The baking soda fungicide is mostly effective as a preventative, offering only minimal benefits after your plants have become infected. Weekly spraying of susceptible plants during humid or damp weather can greatly reduce the incidence of powdery mildew in your garden.

To control powdery mildew on plants, mix together:

1 tablespoon of baking soda
½ teaspoon of liquid soap
1 gallon of water

tnx a lot!

since im already infected ill make the solution a little stronger and also add some h2o2, alcohol and a few drops of Tea tree and eucalyptus oil which is also told to have antibacterial and anti fungi effects

ill use it on a regular basis and it will be documented in my outdoor thread

ps
i found this interesting also
might use it in soil as a preventive measure in the future

DO NOT mix it stronger. Trust me I had that bright idea about a week ago and what once was a gorgeous white rhino at 5 weeks is now a half bleached out shell of it's former self. Too strong and baking soda will burn the SHIT out of your plants.

sulfur burner and or dutch master zone with penetrator will solve your problem

the following thread is great for reference

Serenade.....works every time. http://www.serenadegarden.com/

 

[Darkstarlive]

I hit them with Serenade and going to follow up with Greencure then I'll add ER Herbal Fungicide to a rotation to keep it at bay.

Peace...

Rhizotonic added to Zone/Penetrator for extra effect against PM

Rhizotonic added to Zone/Penetrator for extra effect against PM

With some input I have made an addition to the Zone/Penetrator spray. Add 15ml/gal of Canna Rhizotonic. It takes it to a 8.5 ph. I have also used it on it's own (well, truthfully with Cocowet and sometimes Vermi-T) to beat PM down in clones from transplant all the way through veg too. It works well. The "belief" in addition is also that it helps boost the plants immune system, while speeding rooting to help the plant get healthy and fight the fungus.

This was shared with me by an experienced shop worker, and it proved to work. No one other then him seems to have caught on to it.

SO: I read about the success of Zone/Penetrator and tested adding the Rhizotonic to it. Bingo, no problems. Now I deliver the attack of systemic copper sulfate (this is what I believe really delivers the punch in the Zone combo), but also the ph alkaline shift, and the well proven booster in Rhizotonic. Nice plentiful healthy roots with thick stems is what I noticed in foliar use of it. Great for transplant stress as well. Wouldn't use Rhizotonic after maybe 3-4 weeks of flower. Rhizo is about $60 a quart, and you use so little it is actually super cheap. A real efficient use of 1 spray to cover many fronts.

I also use foliar spay Nitrozyme at week 2, and 3 and then once again at week 4 or 5. I usually add Vermi-T as well to munch up anything on there. I am going to test out adding these to the Zone/Penetrator to see how it turns out. It would be awesome to be able to do 1 spray a week and get it all.
