I gotta give second thumbs up for Regalia. I use it for dunking clones and as part of my IPM. Its pricey but effective.

The problem is PM acts systemic, so you kind of need to approach as if it is.
You can have plants appear "clean" but as when conditions change, it rears it ugly head again. Unlike Green Cure/Potassium bicarbonate (which is more of "topical" treatment) Regalia will aid the plants immune system and also make vegetation inhospitable for spores to "bite in".
I'm probably not articulating my thoughts very well. (not quite awake yet) I just hate to see anyone battling this.
Some of the plagues that hit our gardens can be damn near soul crushing.

Personally if it's like less then 50 plants spray em down with coco wet and water...hell neem will.coat the leaf tissue and ward off new transmission as well as some inhibition to the pathogens sporulating
And i use regalia every 3 days, after your second treatment you shouldnt see many active outbreaks
Other recommended products for alternating sprays:
Cease,seranade
Flying skull(only in night cycle applications)
M-pede
Suffoil X
Even neem will coat the leaf and inhibit spores transmission

Soul crushing is spot on!!
I really appreciate all the recommendations!
Regarding the Regalia...I see it has nothing but 5 star ratings on Amazon...About to order a quart to try, but I see there is a regular version and a Regalia CG... Any preference? Both have the same active ingredient, and not sure what the difference is.
Definitely time for me to start an IPM !
Tangerine, I'd love to hear about your "use it for dunking clones and as part of my IPM ".... If you are willing to share your secrets!!
What amazes me, is I thought I caught this very early...There were only a few small white spots, but it moved from room to room quickly, and has really effected ALL of my mj plants, and the ability to start new ones be it from clone or seed.
Thanks again for the help, and my crushed soul thanks you even more!!

It’s easy to eliminate in cannabis. Amino acids, calmag then what ever else you put in your res.
Creates Pectin so no water for PM tap root to thrive, thus no pm even 85degrees 70% humidity.
All sprays are just bandaids

I am growing organically in super soil! I was actually going to fire up my aeroponic nutriculture, but my clones didn't take because of the pm I assume.

So I am sold on the Regalia CG. I spent a few hours doing some research and it seems like my best option...My only question at this point is one for myself....buy a quart or a gallon, lol.
The Venerate sounds good too. Definitely time for me to incorporate an IPM program....It's amazing I've had so few problems without one!
Sometimes bad things make good things happen in the long run... It was time for some new strains anyways!!

My IPM for my bloom and veg room is pretty basic.
In veg up until the first week of bloom I foliar with Regalia and/or Cease weekly.
Sometimes I use EWC and kelp if I feel real ambitious. I also do bi-weekly drenches of Botanigard.
Clones that I take in get dunked in Regalia. The whole plant, container and all. I follow up with a Bontanigard drench. I leave clones in quarantine until I take cuttings to make new moms and then I discard the original.
If I had to pick just two for my IPM, it would be Regalia and Botanigard. The Botanigard is to kill any nasties in the substrate, particularly root aphids, which have become a plague of sorts within the cannabis community and is said to be responsible for vectoring Hops Latent Virus (HpLV) or "dudding".
Whenever someone posts about fungus gnats and mag deficiencies that they cant seem to get under control, root aphids are almost always the cause. Particularly if they've taken in clones. Fungus gnats vector powdery mildew too. This is why I advise growers to alternate products.
Sick, weak plants are like magnets for pests and pathogens. RAs inject secondary pathogens attracting fungus gnats. The FGs can detect the decaying roots. So its not unusual to have both FGs and RAs.
I have some links saved on my laptop I'll post for ya when I get home.
Hope this helps some.

An old grow I had it keep coming back. What I did was during flower had my temps near 90F. When lights were out about 80F. A little Dawn dish soap and baking soda mixed with water helps a little to rinse off the plants. At high temps PM cannot reproduce. I got this from a gardening magazine. Wish I could find the article to show it. These high temps however can have some negative effets on the grow. Some strains can't tolerate heat as much as others. I was lucky most of mine could. It can be expensive in the winter. I had to run electric heaters to keep the rooms that warm. Also if using enough CO2 plants can usually take more heat(properly regulated tanks or generators only. Cheap methods are a waste). Don't have a big swing from your day and night temps. clean everything and use some kind of safe treatment on the plants. Make sure you have plenty of air circulation. Have lots of fresh air if not using CO2. Use filters on all air intakes. Another thing I noticed was sometimes plants grown from seed were way more resistant. Another big problem is there is PM is in the air naturally from outside. Your location can also plan a big part. If you live in a more humid area or by a lot of water you are probably going to have more mold in the air. We are probably all breathing small amounts of spores of it now. Once you get rid of it, you want to make sure to keep your temps and humidity in check so it doesn't come back. Also it doesn't hurt to use something as a preventative on occasion. I use Safergro Mildew Cure Plant Protection concentrate 2 teaspoons/quart in veg and early flower. It is organic and just ingredients like cotton seed oil, corn oil, and garlic oil. I like it better than neem oil. PM is a big nightmare for all kinds of gardeners. From growing roses to grapes to cannabis, it's everywhere and I hate it. Best of luck!

From. What I learned powers mildew likes hot humid environments. How I combat it is just keep a clean area. Temperature and humidity at the right level. When I add my second light in my tent is overheata and drive my temp/humidity all crazy. I got a handle on it now. I started growing at night to work with the decreasing temps and not against them
I'm in the Mojave Desert. My humidity is usually between 10% and 15% I had PM that I could not kill until Regalia. It got me to harvest. I can't recommend it highly enough. As for Fungus Gnats I used a root drench of 36% Permethrin. They were dead in 2 treatments and I gave them a third to be sure.

This definitely helps...I had never heard of Hops Latent Virus (HpLV) or "dudding". I'd love to read your other info when you have time to post it....Thank you!!
I am thinking there's something more than just powdery mildew going on...The case of PM I have seems so minor compared to pics I have seen, but the plants growth, and more so my younger plants / clones stunted growth tells me something is up.
Thing is, I have not brought anything new into my grow areas...Other than a new batch of super soil that I used raw bat guano in instead of the usual Happy Frog brand. But no new clones, etc....I've ran the 3 same strains indoors for years now.
And ironically, I did have an issue with fungus nats about 2 years ago, but it wasn't severe and got through. Haven't seen one since.
Venerate, regalia, grandevo, and Botaniguard 22WP and M-Pede all sound like great products...Definitely going to order some Regalia and Botaniguard 22WP today for starters. The GH Exile seems to work great for pm too, but they recommend not using it more than 3 consecutive weeks, but perhaps I'll keep that in the mix too. GH has some other IPM products but they are just as expensive as the and Marrone Bio products, and since you all recommend them so strongly that's where I'm headed!!

PM does seem to flourish when the leaves get too dry from extremely low humidity.
I think this might be why so many struggle with repeated attacks when using just potassium carbonates. It dries out the spores but also dries out the leaves.
I'm doing foliar of Regalia today
If I remember I'll do before and after pics. Another added benefit - the plants love the boost.
This is one of the earlier threads with some of the first reports of "dudding". There are reports that pre-date this, but these reports are unique because they came in so rapidly from growers all over the country.
Dud Identification Collective Knowledge. - Cannabis Infirmary - International Cannagraphic Magazine Forums
Dud Identification Collective Knowledge. Cannabis Infirmary forum at International Cannagraphic Magazine.
When Gorilla Glue 4 was first passed between growers it gained a lot of attention. Everyone started to go crazy trying to obtain a cut. One of the first growers to obtain GG4 decided to to bring cuts to the 2014 HT cannabis cup to give access to more growers.
A noble venture, but the grower had previously battled mites and root aphids and didn't disclose this prior to selling the cuts.
-I don't include his info to put anyone on blast or divert your thread. Just trying to bring a little clarity and context. (something often lost on these forums)-
There were several hundred cuts sold at the event and not long after, the reports of "dudding" started to come in.
If you dive into these threads, you'll see the denial was strong. Many dismissed the reports others claimed it was nothing more than "grower error". And who could blame them. The first cuts that went out were free of pathogens. But the reports were coming in rapidly and from very experienced growers.
With hundreds of infected cuts now being passed, it was only a matter of time before the dispos started selling them.

You are right! I forgot that Bayer bought them out. The GH Exile I commented about is certified OMRI though, cheap, and seems to work well to control pm...and i will say that Bayer makes the best bedbug insecticide out there, Temprid SC, but yes it is some toxic stuff and banned in CA. and not allowed for outdoor use in N.Y.!!

Don't be a tool. Providing growers with info to implement an effective IPM isn't a Band-Aid.

This dudding shit make me nervous!! Especially since my girls are exhibiting some signs of a calcium / magnesium deficiency, which is a sign of dubbing...plus their stunted nature, etc.
Allrighty then, I need to get my order in for some Regalia and Botaniguard 22WP for starters. and hope to God i don't have any dubbing disease!!!! And time to mix up a fresh batch of supersoil !! Cha ching, I see $500 disappearing real fast today, lol. As my old (very wealthy) boss use to say..."It's only money"
