What is everyone's preferred method against PM?

just out of curiosity nug, what is your RH on lights on and lights off?

Click to expand...

35-40 constant....good air flow......only 5 degree day/night temp differential....

Is the PM showing up on your clones or your seed plants? Any specific strain your are seeing issues ?

Eagle 20, Green Cure, Grower's Trust Powdery Mildew Killer, and Pro-Tekt!

is there any vegetation with PM around your house? you might be bringing it in. Is the fresh air coming from outside? do you have an air filter on the intake? Do you have fresh air coming in 24-7 or your run a dehum with lights off with no fresh air coming in?

I was thinking the same thing about the air filter on the intake... Is your intake passive, Nugs?

I'm battling the shit for the first time in flower, ever. I'm so bummed... found two little spots on leaves today at almost 6 weeks and went nuts with the GC... that's what's always helped me in the past on vegging plants.

Everyone in here should look up the herb HORSETAIL !!!!

A tea brewed with it and foilar sprayed will get rid of any fungi, and is actually benificial to your plant, instead of just correcting a problem.

Used EXCLUSIVELY on Biodynamic farms/vineyards in Europe and beyond.

Right On rising moon!
this is valuable information here.

In my search for Horsetail I ran across this: http://forum.seeddepot.nl/showthread.php?1695-How-to-prevent-and-treat-powdery-mildew-with-horsetail-tea

I know it is on another forum, but I'm digging the info. Going to make a batch today. I'll keep you posted.

Thankyou for the enlightening info.

I swear by the sulpher burner. Along with cleanliness, de-humidifiers, and not accepting outside clones I've beat the pm for over a year now. Knock on wood. I burn once or twice in veg and go crazy first week of flower. 2-3 days burning almost entire dark period. If you can't beat it you have to bite the bullet and kill everything and start anew. After crazy cleansing, sulphing the entire room heavily and waiting a bit. Sulpher gets everywhere. Lamps, walls, floors, plants and everything else. Keep plants growing happy and fast and they won't get hit in my opinion. Strain is a huge one as well. That's part of my protocol, Quality, rugged, yield. I don't spray anything accept really compost tea.

i just ordered some powdered horsetail and will mix up a batch as soon as it lands....

couple things...2 tsp per gallon of greencure is kinda weak i go as high as two tbsp. my low is 1 tbsp. if you have an open system pm spores would be there regardless of your outdoor harvest. they are outside in abundance during the winter. you can hepa filter your intake. might want to use oxidate alone, or you can combine it with the green cure. also dip your clones in oxidate and use it in conjunction with molasses for a high brix spray during veg. also might want to up your calcium..

Yeah, I was running two tablespoons of the GC as well... I must have read incorrectly when I was reading your application rate, Nugs.

Hey, also Nugs, when you were using the Oxidate, it was the premix right? I've been meaning to ask you for awhile what your dilution rate was on that. I found that using the spray straight out of the bottle burned my foliage a little.

I'm in it to win it with the horsetails, though. Just ordered some online... went searching around my neighborhood where they are normally abundant, but somehow came up empty handed.

Good info, as always, KK.

What is this Oxydate besides plain old hydrogen peroxide? Is there something more to it than that, or is just another ripoff for the uninformed?

Looks like its H2O2 and PAA (peroxyacetic acid). Maybe the PAA is what makes it "special".

anything over a T/gal torches the leaf tips, so that is where i draw the line....of course i use liquid soap for a surfacant with it........i mix the oxidate from concentrate......oxidate works with acid...it is 3.1 PH....green cure works by raising the PH of the leaf surface its PH is 8.1.......i have tried alternating them with moderate success, but i certainly would not mix them....you would prob end up with a neutral PH where PM can thrive....i am really interested in a tea that is 100% natural, and will not torch leaf tips or fry pistils..(i have tried compost teas with little success).......excited about the horsetail...

it is also really important for me to be able to spray without a mask......oxidate smells like sulfur, and it will cook your lungs if you breathe in the vapors, Serenade fucking reeks, GC is odorless, so i like it, just wish it wouldn't fry my pistils...

The horsetail should smell really good!

Makes me want to drink it every time I mix up a batch.

Two brewing methods: (copied from city food growers website)

Mix the dried plant and clean water together at the rate 100g of plant to 2 litres of water.

(1) Bring it to boil and then let it simmer in a covered pan for 20 minutes and once cooled leave it stand for two days before using.

(2) Soak the leaves in cold water for two weeks.

Application at any times of high moisture when you have plants more susceptible to fungus. Especially important to prepare for times of ascending moon to full moon and coinciding with a perigee, when the moon forces on earth are very strong and create potential for high moisture levels.

It can also be used regularly as part of your general fertility practices in your garden or orchard.

Quantity:
For 1 acre – use 1/3 of a litre of preparation in 7.5 litres of water. Thus, 1 acre would require about 20gms of equisetum plant.
For a household block – use 1/6 of a litre of preparation in 3.75 litres of water. Thus, 1 houseblock would require about 10gms of equisetum plant.
If you plan for multiple applications over time, which would be helpful for general fertility of your garden, then multiply these quantities by the number of times in a year you intend to use it.

its not hydrogen peroxide its dioxide. when i mixed oxidate and greencure the ph remained high. but the orp was lower. ill lower the orp in all my foliar sprays if im concerned with pm. as for the burnt tips, ya they get scorched pretty good at 2 tbsp per gallon. i figure its worth it.

Hey Nugs, you ever get your horsetail? I'm boiling mine as we speak. Going to give it a go tonight.

Mixed a batch 2 days ago. Rising moon is right. It smells great....just like tea. Earl gery. Dark stuff. Going to do a foliar spray tomorrow.

I have not seen any physical pm as of yet after I did a 2 tsp batch of GC a few times.....however there are still some raised bumps on some of the young leaves, which leads me to believe I need to keep vigilant. With the addition of the horsetail I may be able to keep it at bay.

I really think its great we can share our experiences and all this valuable info......its so helpful to me personally.

Thank you everyone.
