I was wondering if anyone has expirience with POWEDERY MILDEW. I have been fighting it off for 2 weeks now. At first sign I used Azmax and when it returned a week later I have been using a spot treatment (SNS 244) a Thyme Oil based solution. It does not seem to re-appear in the same spot but shows up in other spots. So far they are only dime size spots, but I am getting tired of crawling around spraying them on a dialy basis. If anyone has had a succesful crop with managed Powedery Mildew,please let me know. Or is it possible to make it go away perminently????

This has been stressing me the fuck out, so please share stories if you have them!!!!

Thanks all!!!!

I have heard of a company that makes a product called no powdery mildew they also make a product called no spider mites, have heard good results of the spider mites, havnt heard anything about the no powder.

I've heard hydrogen peroxide takes care of that stuff, but I don't know. I know Jorge Cervantes has a video of it on Yoo Toob. :wave:

forest gump;your best solution is to take out all of your plants and wipe your grow room down with bleach or some sort of mold killer after you treat your plant.if you have a fan blowing on your plant it will spread the spores around and if not cleaned will affect not only this grow but it could also spread to your next grow in that same spot.. hope this helps... sf

** I humbley bow with a fist to shaolin a fellow monk.. I likeyour WU-TANG Style**** lol :D

Man you dont even know.. I am stresssssssing.. I read up on mildews and read about disinfecting ALL your shit. That was my mistake. This is my 4th grow using the same shit and the only thing I have cleaned is the pots. The funny thing is that this is the first time I havent had gnats **so far***

Let me go see if I can take some pics.....


Well to my relief it hasnt entirely spread, the SNS 244 FUNGICIDE
seems to instantly kill the mildew and so far doesent appear in the same spot (although it's only been a week of daily spot treatment)

But damn out of 12 plants I sprayed about 7 leaves of various trees... I check every fuckin leaf..

There has been about 5" of growth in a FUCKEN WEEK!!!! LMFAO

It's White Rhino and GMP so hopefully I only have 6-7 more weeks to go so hopefully daily treatment will prevent it. I will probably do an Azamax treatment in the bathtub next week.. but these BITCHES are getting pretty huge I think I should have flowered 2 weeks sooner

The best of us have fought this before and it's really better to chop them down. First, I wouldn't want to smoke moldy pesticide medicine, second it will definitely spread to nearby plants regardless of what you are doing, thirdly don't even think about taking clones from a powdery mildew plant. Once the plant has it, it is IMPOSSIBLE to get rid of completely. It lives inside the plant and will never go away. The disease will spread to clones.

Start keeping your humidity lower. It thrives in moisture and poor ventilation. I got this once because I was excessively misting my vegging plants with water. The disease gets much worse during the flower cycle, trust me. It also stresses the plant slowing growth. If you get to harvest, it will be difficult to tell powdery white mildew from the tricomes.

We all learn the hard way because the practice of cannabis growing is so taboo. Don't even get me started on spider mites...

Like I said this is the first for me and I have realy never heard any stories of succesfull crops with PM. The good news is the the spots are less than half the size of a dime. And pop up on a leaf or 2 on a few plants in the garden almost daily. Like you said though I am worried of being able to contain any spreading once crystals are thick. But crystals are closer to the bud then out on the tips and exposed leaves.

And you mentioned te plants getting stressed and a slow growth rate, but since I noticed the first spec almost 2 weeks ago they have grown a little over a foot in 2 weeks with no signs of stress.

But Maaaaaaaaaaaan! CHOP THEM DOWN!?!?!?! fuuuck I have to think about this one

Fact #1. Powdery mildew can grow in any humidity and doesn't need water to survive.
# 2 Powdery mildew goes systemic, meaning throughout the plant, in and out.
#3 Only an anti-bacterial/anti-fungicide compound that treats systemic fungi will work.
Finally the only product or treatment that works is sulfur. Before penicilan, sulfur was used as a battlefield dressings.
A sulfur burner is the treatment that works allways. I use mine routinely during early veg stage and it inoculates them against the spor. Using it during budding must be done no later than week 5-6 into budding. Now my good man I have given you some info that you requested and a little education. If you want more specifics visit my tread and i will run you through all the specifics on usage and schedules. My tread is for education for all to learn some trick from an old guy. Don't be shy.

Wow I like this GUY !!! teach me oh wise one!!!! lol

Yeah I have read about sulfur burners and am a bit woried becuase I have to others who live in my house. I am thinking of getting new curtains (Black Panda Film) and a new floor covering tommorw. I will probably give them an Azamax Bath and put them in the new area.

I am definetlygoing to follow your threads... And that you menioned it I am going to look further into the sulfur burning and see if I can do that shit without accedentilly killing everyone in my house.

From reading your post SG1 I see you dot use commercial nutes so I assume you dont use fungicides either. But I have read alot about this and I am also thinking of this ACTINOVATE | Organic Fungicide | Stops Disease | Safe for Pets, People and the Environment | Natural Industries, Inc.

What you think?

And like I said it very small specs but I am sooOOO worrie about it destroying my crop and or having any mildew in my buds.. WHHHHHHHHHHHHY!?!?!

PM will always start off as little specks. They get much bigger with time, even with treatment. Sulfur Burning would be the best way to go, but it still won't completely kill it, only treat it.

Just because you don't see it, doesn't mean it's still not there, (ie with clones). We had a local dispensary here in Cali give away some powdery white mildew clones unknowingly. The bud tender told me after I asked him why I was getting little white spots all over. When I bought the clones, they showed no sign of PM and it didn't start developing until after a couple of weeks of vegging.

It then spread to everything because I didn't want to chop her down.

When you're in full flower (about a month or so in) you will notice the tiny spots have gotten much larger by now and have spread up the stem, seeping in between the buds. Then finally, it will consume the bud completely.

You will notice stressing in mid flower. The vegging cycle doesn't seem to effect the plant much since new leaves are constantly growing so rapidly.

I submitted a picture of a Jack Herrer plant I grew with PM. This was the one I got from the dispensary. I got her to finish flowering and everything. Towards the end of flowering, I didn't want to use pesticides, so I used hydrogen peroxide to melt off the PM.

The picture is not the greatest because it was taken years ago with my phone. But you can see the damage is obvious. It almost looks like tricomes if you're not careful.

Instead of smoking this crap, I bubble bagged it and put the hash into edibles for safety.

After harvest, I replaced or wiped down everything. Since I now have control over moisture and ventilation, I haven't seen it since.

Good luck with your babies. Just remember your lungs are more important.

organicide, or a sulfur burner! Sulfur burners are a last resort, and depends on how much money you want to continue to throw at them?! But, if it works your have a crop(a questionable one, but a crop) if it doesn't work you chop em anyway and can treat the room with sulfur. Not the best option, but its what I had to offer. Best of luck, hope it turns out well.

Ohhhh WOW!!! wells seems eitherway you cut it I am FUCKED!!!! or my plants anyway..

It is difficult for me to admit, becuase now they are thriving!!!! and it only appears as specs here and there.But from stuff I have read it seems once you have it on the plant (in the plant) it will nearly never go away. Similar to Broncitis for humans. I think it goes dormant..?

Well I am going to take all my plants out tonight, throw them in the tub and soak them in Azamaz. I will cut unwanted growth as well. I am then going to put them in a spare room while i disinfect the growroom with some heay duty antibacterial bleach shit.. I also got a new cover for my carbon filter. Man I prey this shit works. I typically keep my harvest for myself and just end up giving it away to family and friends. But I smoke most of it LMFAO

Even though the crop looks amazing at this point from what I have read I almost feel like giving up and junking all those beatifull bitches!!!!!!!

I will take pictures tonight when lights are on and I have completed the tedius task of santizing everything

Well here it is 2:15 am and am final winding down from disinfecting my room. I took out each plant 1 by 1 took it to the bathroom and gave them a good Azamax shower with a regular spray bottle. I sprayed and "jerked off" each brach. lol made sure to give the branches and leaves a good scrubbing. I then sprayed down my grow room with some bathroom cleaner type shit "kills 99% of bacteria." I also bought a new charcoal filter cover. I then turned the lights back on let it set for a little while and put them back in. I am going to continue to watch them closely, feed them plenty of compost tea and spot treat the next few weeks.

wish me luck :(

BTW
I am watching some old 80's movie called Troll! Some trippy shit!! LMFAO

Trolls in some mystic garden in some dudes room.:smoke:

Use serenade. Powder mildew shows up after it has infected the plant for at least a week. Serenade will kill the infection, azamax won't do anything as it's an insect growth inhibitor. U can also mix 10% baking soda an 90% water to spray on the leaves to change the surface ph to where it can't grow, although that just buys u time because it doesn't do anything to kill the infection

Man I have spent so much time researching this GOD FORSAKEN PM!!!!!!!!! I cannot find a definate answer.

Well since I have disinfected my grow room and showered my girls in Azamax they look good but I know it's goingto return it's just a matter of time. I am also steadily feeding them Compost tea high in bacteria and hope this does somthing to fight off the the internal infection.

god damn I think this is my last grow LOL! :cry:
