PM wash

Any of you guys use this stuff? I had a few GDP that had a little pm on the lower leaves and sprayed them once every few days with this stuff and the pm never returned. It didn't cause any problems for my buds either like taste or smell. I think it's just a peroxide solution? Anyway I though I'd share that it works for pm. Even though pm is systemic it stops the mildew growth on the leaves and buds from advancing.

Any of you had luck with this stuff? They also make a product called mighty wash for pests and one to rinse these products off you plants. I can't remember what they call it though?

I'd recommend some microbial treatment, Lactos bacillus or even a good spray down with compost tea. Best of luck!

No. Powdery Mildew IS NOT SYSTEMIC.

3 words.

Know your enemy.

Homelessbeans swears by this product if i remember correctly. It did nothing for me.

Everything I've read and been told has lead me to believe it is systemic. If you take cuts from a plant that has it it will come up on said cuttings in flower. I've had that happen while cuts from different strains did not have the PM. I could be wrong though?

it absolutely is systemic. a plant is sick when it has p.m. there are very few products that treat it systemically and those are usually very harsh products, but they work by curing the plant(systemically)

really, so a fungal DISEASE isn't in the plant. Please elaborate Smartass. I suggest you look up the meaning of a pathogen.

link no good tard

Are you too stupid to cut and paste it? Tard... How original. Dont get all ass chapped because you chose to run your mouth instead of reading. If you and the other 90% of the fucking retards on this site want to believe horse shit weed lore, be my guest. But dont, for fuck sake, think those of us with the ability to research will allow you to spread misinformation. Use your brain.

I'm smart enough to not download unknown stuff to my computer, Why don't you post up whatever it is you think your supposed superior knowledge has. Is it your intention to teach us something? or just to try and inflate your ego because you read an article. If anyone is butthurt, It appears to be you,please fill this out.

" before you get lippy again"

Eh? Can you point out the part where he is "lippy"? Do you consider someone not agreeing with every word you say to be getting "lippy" with you?

Lighten up Francis.

I talked to 2 different growers that I know today and they both run grow shops as well. Both of them said PM is systemic. I looked online and I didn't see anything that would lead me to believe it was not systemic. Please post your finding on this. I would love to know how to treat it more effectively than I do currently.

I personally have dealy with powdery mildew for quite a while now, and let me tell you, i believe IT IS A SYSTEMIC. No other way around it. The only cures I have found are eagle 20 when in late veg (if outbreak occurred) or green cure as a preventative soak from about the time it was 2 weeks old.

Let me tell you this, once you get it, it is a son of a gun to get rid of.

This stuff will kill PM and it will stay gone. I wouldn't use it on buds.http://www.amazon.com/Eagle-20EW-Specialty-Fungicide-Concentrate/dp/B003407B9Q/ref=sr_1_3?ie=UTF8&qid=1359771186&sr=8-3&keywords=eagle+20ew

^^^ Agreed, and absolutely DO NOT use it while in flowering!! One sniff of the stuff and you'll know why, I really didn't want to use it, but when you've tried pm wash, serenade, milk 9:1, alkaline water, and zero tolerance, eventually ya say fuck it! I'll try the nasty systemic. And in this case, the shit works, just use it in VEG ONLY. I spray early on and then once right before I flip the light!

Pm is not a systemic fungal disease. Eagle 20 is a systemic fungicide which means it is xylem/phloem mobile through out the plant and protects old and new tissue because of this. PM does not spread though out the plant via the xylem/phloem only superficially on the leaf surface. There are fungi that are systemic in plants, both parasitic and beneficial, but there are no known Erysiphales spp. that are systemic. PM starts first by spores, in our case conidia, that germinate on the leaf surface. Mycelium spreads across the leaf surface and inserts cell structures through the epidermis of the plant called haustoria. These cells sap nutrition from the plant and is the reason you see yellow spots after its been "washed" away by PM wash. This may be where the stoner misconception of "systemic" comes from. Even though the haustoria is inside the plant the organism itself does not emerge nor can it survive/reproduce inside of the plant, it needs its reproductive and vegetative structures that exist only on the leaf surface. PM is considers an obligate biotroph.

PM is very difficult to fully eradicate from an indoor environment and is another reason I think a lot of people think it is systemic. Its hard to ensure that all conidia have been destroyed in the environment and they cause reinfection if they are not. When you see a spot of PM on a plant you are actually looking at millions of tiny conidia stacked up in chains off the leaf surface. If you see just one spot of PM anywhere on a plant you can be sure there are are shit load of spores in the environment and it will only be a few weeks before you start seeing it everywhere again.

The link Vertigo was so kind to post up is a copy of Hemp Diseases and Pests by McPartland, Rob Clark and Dave Watson (better know as Sam the Skunkman) that I sent him. If you dont own a copy I suggest you all download and take a peek. Its time to put down Jorge Cervantes and Ed Rosenthols "Grow Bible" and step out of the stoner misinfo soup these forums seem to cook up. One of the first things you may notice if you go to the PM section is that there are actually two species of fungi that attack cannabis as "Powdery Mildew" which is a catch all for thousands of species that cause the same disease. Interestingly enough one is able to be controlled via the environment(RH and Temp) where as the other can germinate at 0% RH and High temps. Probably why some have such great luck with a simple change of environment and a systemic treatment such as E20, Quadris, etc.

Theres your problem! EVERY chucklehead runs a grow store now post 2009 and they are all "experts" in their field! Dis-information sells products derrrrr, trust me been behind that counter!

And there you have it. YOURE DEAD FUCKING WRONG! GOOD LUCK WITH YOUR MISINFORMATION ENGINE YOU CALL A MOUTH. Pleasetell your 2 all knowing grow shop employees to shoot them selves in the head also.... Youre welcome.

thanks bt, youre a gem....

Talking to yourself?

I'm not taking sides here. I've never had PM, so I've never really bothered to research so you could be 100% correct .... but you're acting like a dick either way.

Again, lighten up.
