Powdery Mildew infection

G

Guest

My friends grow-op is loaded with mildew, last week he sprayed with some neem. Just once, it looked good a couple days later but went to shit between yesterday and today. He is really lazy, He knew that this was happening and never bothered to say anything. So he called me asked me what to do I told him he has to lower his humidity, and also get some neem, or some milk and water. What I didnt know was that he is 5th week of flowering. So I finally got a look at them a most of them are bad. I was wondering about UV generators, I heard that they kill mold and bacteria. Know if anyone know about smoking these buds. I have in past years before I started growing smoked moldy weed and It got me high but tasted like shit, just wondering What kind of health risk might be at hand for smoking the powdery mildew buds?

neem doesnt kill mildew.... you need to go to the garden shop and get something designed to work against mildew. I wouldnt smoke moldy buds, you can run them through a water/ice hash process to filter out the mildew. That is probably your best bet. Ozone wont do a thing for ya...sorry.

Au contraire my sunny friend, ozone kills mold quite well indeed. It wont remove mold from buds/leaves but Im not sure thats the case yet.

bleach and water to wash down the walls...lower the humidity...and get some of this...Serenade

from their site:
"Stop Dozens of Tomato Diseases with a Single Natural Product
Thousands of commercial growers use Serenade® Garden Disease Control to control foliar diseases, because it's so safe you can spray and harvest the same day. Certified organic by OMRI, Serenade® Garden Disease Control contains Bacillus subtilis, a soil-dwelling bacterium that controls leaf blight, black mold, powdery mildew and many other diseases.

# Works on all fruits, vegetables, flowers and ornamentals.
# Available in two convenient sizes, a ready to use spray and a concentrate.
# Controls anthracnose, bacterial spot, leaf blight, early and late blights, rust, powdery mildew, gray mold and black mold, and scab.
"


unless you get rid of the spoers, they will continue to haunt you and your bud.

smoking moldy bud will give you the worst respiratory infection you have ever had. no fun!

good luck to you and your friend.

Ask about the serenade at your local grow shop. If thing are out of control with the powder mildew and you have a sizable grow the last ditch effort would be to buy a sulpher vap. I bought one and after two burns all has been erradicated and doing fine now. I use serenade regularly now to prevent any reinfestation and haven't seen a sign of PM in months. :wave:


Stop by the chat room for a live up to the minute coverage of PM control. :woohoo:



PS You first need 50 post to ebter the chat room. CYA soon!

Moulds and Mildews cannot be eradicated completely from the environment. Spores are everywhere and cannot be stopped from contaminating a grow room. All you can do is create conditions in the room that do not favour growth. Relative Humidity should be less than 50% to stop growth. If you live in a humid part of the country, I would invest in a dehumidifier.

Good luck

yeah I should have worded that better. Ozone kills mold i.e. in your basement....its not going to remove the mold in a bud though.

i just had a problem using my dehumidifier, seems mold was in there , and when it turned on, sent spores everywhere. someone said to clean it once a week with bleach water. i live in a rainforest, and am fighting everything. havent smoked anything good in over a year, due to wasting my time on overrated seeds that werent as strong as the local rag weed. bullshit!!

Low humidity and lots of air movement .......... also 1 tsp of baking soda and a 1/2 tsp of epson salts per litre of RO water ........ spraying liberally,keep humidity around 50% and no more mildew.

:woohoo:

This works GREAT, IMHO. Please give it a try and post your results, remember ymmv. Mildew cannot tolorate alkaline solutions.

1. Ph some R/O water at 8.0 - 8.5.
2. I use a bit of dawn dish soap as a wetting agent(you have to use some sort of wetting agent to make this stick).
3. Add about an ounce of milk per gallon of water.

This has worked great without the need for chemicals. I hate using any chemicals!!

but, can any of these methods be used in the sixth week of flowering?

Sprays should be ok in 6th week.... but your cutting it close I think.

Sulpher can be used up to two weeks before harvest.

Well it can be used but it leaves one hell of a residue and throw your finger hash away and forget about using the leaf for anything. Trust me I know all about that and I just threw a 18 gram ball of finger hash away from sulphur sprayed with 3 weeks to go on a buddies harvest.

With that being said, sulphur is probably the best way to go.

If I have a Powdery Mildew situation I make sure my mamma patch gets a routine spray but not too close to cloning time because the cuts get burnt in the trays once humidity levels get high.

I'll spray my flower room after the newly planted stock gets some decent growth, say a week in. Use a diluted solution at first. I'll spray no later than 2 weeks into flower though. I usually don't taste it in the hash or oil then.

I use Defender for this. Be careful of their mixing instructions. It's too strong for pot usually. Mix lighter.

A Sulphur Burner can be put in your room. It slowly burns sulphur which helps kill the airborne spores.

Spray rooms after cleaning with bleach or Iso.

The battle can be won. I beat it in several big set ups at once. Took over a year. The biggest weapon is being self contained once you do beat those fuckers.

I'd say that the person who is at 6 weeks is just going to have to take the hit if he's cropping at 8 weeks. Til then he can wash with water and the mild remedies suggested above.

What is the consensus on Sulfer Vaporizing time tables?

I am at day 35, and I have got some bad spots started and I don't want it to get out of hand with ~ 4 weeks left to go still. I had a badass outbreak last crop, COVERED some of my plants, killed them dead basically threw the buds away they were so white. I really do not want this to happen again.

I have had the sulfer vaporizer for this whole crop, I have done about five 6 hour burns on different days and it still persists! Should I keep burning??

Believe it or not I used to be dukeyduke and PM is a bitch to get rid of. If you are in you 6th week of flowering there is a product that you can use to control the pm up to harvest time, Its called Fungastop L&G one of my grower friends suggested to me. Its a all natural product and wont harm your buds, I have used up to a week before harvest with no problems, to bad taste, or smell. It really works after you spray it the plants look brand new, but still it doesnt completely kill the infection, the spray only controls and contain it(at least for me thats all it did.). here is a link to the product the only I could find.

Hey everybody! Listen to this!

I recently had a BAD mildew outbreak in my room. Not really the whole room, but in a small spot it got really bad. Basically, I am running 24 strains of clone cuts from the club in oakland right now to pick some good keepers. Anyways, one of the strains, Cave, was /is just mildew magnet. So, I used my sulfur burner, sprayed it with hydrogaurd(Bacillis subtillus), humtea, etc trying to get rid of it, and nothing was working. It was so bad I was going to pull this 1 plant, because it was spreading from that point.

So I was about to pull the plant, but I figured what the hell, if I'm going to kill the plant, I might as well try some shit out on it. I loaded up a sprayer with hydrogaurd at a 1:4 ratio. The bottle strength is 15ml per gallon. The ratio of 1:4 ends up being 60 x the recommended strength.

Anyways, the punchline is: It kills mildew DEAD. Shit disapears, and there is absolutely no ill effects, and is safe to use up until harvest, with no ill effects WHATSOEVER. Bacillus subtillus is an absolutely harmless bacteria to you and me, but death to molds. Wait until your lights go off for the night, and soak them bitches down. You won't regret it.

I shopuld mention I've been doing this every 5 to 7 days now for about 3 weeks, and not ill effects, right up to harvest. Just be sure to spray them down when the lights go off for the night, and leave your circulatin fans on to be sure it is dry before the lights come back on.
