ok had a patient walk in to the store the other day and ask about a good way to get rid of it without clearing everything out and bleaching everything (which is what i suggested) do to the fact that his grow room doubles as his sick wifes sewing room (in my opinion BIGGER reason to clear everything out and bleach) is there anything safe he can use without all the "work" which is what i think hes trying to avoid

Horsetail Tea
put 100grams in 2L of water overnight, then filter out the horsetail, you should be left with brown undiluted horsetail tea.... add 8L of water to get 10L of diluted tea.... heat over stove for 20 minutes, then wait to cool.
spray this for 3 days onto plants with PM then in a week spray for another 3 days

diluted milk sprayed on and left for a couple of minutes then washed off thoroughly

warning ,
hairs will turn brown instantly
dont get it on the soil or in a rez whatsoever as you p/h will be all over the shop or you will loose the plants , in soil flush if it happens
any leaf thats not great will be killed off instantly and the plant may have a shoddy look to it if say theres a degree of tip burn

it does work but has a degree of risk , if the plants healthy then once done you wont notice but if not then its a little corrosive

horsetail tea works best and you can spray at any stage, it won't have a negative effect on your plants

PM is systemic. Don't let anyone tell you there is an easy fix.
Its simple, Thank the grape industry and their experience with systhane / eagle (myclobutanil)
1-2 applications to completely remove PM

The above course of action is not recommended to hippies as systhane contains no whale tears or skimmed milk

peace

According to recent studies PM is not systemic as previously assumed and thought to be . I remember being taught in Greenhouse management class that it was and my old notes from MSU's Master Gardner Program said just the same .

I have always taken it to be so until recent research showed different , but none the less I still take all precautions and this seasonal bullshit this year is wreaking havoc with Pm infestations state wide. , Indoor PM is more prone to attack environments where the temp and humidity swings are most prevalent , such as Basements and Pole Barns and outhouses lacking insulation .

There are many PM products and methods of destruction but prevention is the major key word when all said and done .. In this situation it might be feasible in between grows to use Ozone or even Sulfur burners but if permissible budget wise UV-C clean Lighting is the cats meow as it destroys pm spores on contact and this can be shined on the plants , walls and all other surfaces as well

I hate to be the lawyer here, but I believe some "systemic" disagreement here may be based on context.

Systemic: adjective

1. of or pertaining to a system.


2. Physiology, Pathology .a.pertaining to or affecting the body as a whole.

b.pertaining to or affecting a particular body system.


3. (of a pesticide) absorbed and circulated by a plant or other organism so as to be lethal to pests that feed on it.
 
Fucking plant Herpes.... It's a nightmare

I use Green Cure on my Veg as a preventative. If my bloom get's infected, I use a Hydrogen Peroxide/water solution to treat it. The HP spray can be used up until the day of harvest and it works great. Just don't be an idiot like me the first time I sprayed ... TURN THE LIGHTS OFF!!!!

PM is a nightmare for farmers of many different crops . I have fought it mostly outside due to it being so prevalent there . It has wiped out a few of my vegetable gardens 15 feet from my grow room but never did I find it in my grow due to diligent environment control . Only had one round with the shit inside and it seemed to honestly be systemic and the Cut was Ken Estes GDP F-1 , I burnt it with gasoline and never looked back :)

Yes lets not forget this too ^ .


I really think it has to due with environment more than anything but then again it is not worth the time to argue as it does not matter to me if it is or not .. FUCK PM

Personally I treat PM spots and burn infected plants. I've watched some win and others lose trying just about everything :(

get your temp from swinging at all and thats a big step to beating it. a friend of mine put plastic over all of his exposed galvanized ducts and started fresh from seed again after getting a heater to make sure the room didn't get too cold and he was good to go. i know it sounds like a lot but not really he just cleaned it up good. he said the galvanized ducts was probably the cause of his. they cause the stuff to form i guess when the temp swings bad and then it can spread to whatever it wants from there. (words from an old farmer) he said nothing really gets rid of it and you can't clone away from it no matter how early you get new growth to clone. if its got PM its always gonna taste like it was grown in a wet basement so id cull it all and start fresh or start planning a grow out soon.

green cure aka baking soda, etc...none of this worked for me. It may prevent it from spreading but sooner or later it is going to bloom again on whatever leaves you missed. Eagle20ew - 1 or 2 applications (veg only) knocked it out completely for me. Combined the eagle attack with a good bleach cleaning of the room.
