Hi guys.
I got 9 plants flowering at the moment and because i´m quite the noobo i intended to have plants at different stages of flowering in order to harvest as buds go ripe. That way i thought i could do a 2nd crop on my plants, taking better yields and prolonging the life of my beloved plants.
Sounded like a plan, or so i thought, sadly the white powdery mildew arrived in one of the older clones, Cannaloupe Haze from DNA, as the plant grows larger so does the mildew and now it´s starting to spread like wildfire.
I´ve been using NeenRepel and a specific treatment from Canadian Express called PMT, both are sprayed throughly on all the plants but i dont see the results i was looking for. And as time goes by and buds get fatter and frostier my fear of having my crop all contaminated with the damn spores from the mildew is on the rise...Am i fearmongering!?

My question is is there any other kind of treaments against mildew that arent folliar application. Some that i can dilute on the water and feed my babes with...?
The older plants (CannaloupeHaze&LemonSkunk) are on the 6th week of flowering and the younger ones(BlackDomina) entering now the 4th week.

Many thanks for all your help

Stay Strong & Green

hey,

I had the powder mildew. I used a sulphur pot to treat it, but this method does make a big stink.

What really cured it was doubling my extraction. I went from a single 4 inch extraction to an 8 inch extraction. You need excellent air extraction to keep it away.

Good luck!

Thanks Rand.
Just yesterday i´ve added a extra fan inside the cabinet. Trying to provide better air circulation to the plants.
I´ve bought the sulphur candle allready but my cabinet is buildup in my room and the wife is quite smell sensitive
But my major problem with the sulphur is, do you think there is a point of using the sulphur candle and them return the plants, mildew contaminated, to the clean growing space.Doesnt seems like a very good plan But it was my plan...
One question, doubling the extraction would end up my mildew problem? Or is just a prevention measure in order to avoid the damn thing...? Measure that i need anyway after i end up with the actual infestation

Do i make any sense or is it too early in the morning.... ...the joint seems to be too big for b4 breakfast

Thx again Rand

Peace

A sulfur candle will coat your plants with toxins, a sulfume will give some control but really should not be used during flowering.

Essence controls both powdery and downy mildew.

Plants need to be in the grow room when you do the sulpher. The idea is you are attempting to change the ph of the leaves to make it toxic for the mildew.

tbh I'm not a mildew expert. I just did what my local shop explained and it took care of it. I would also isolate the infected girls if you can.

e2a:

OT1 has the gist of it far better than I. And again, I used a sulphur pot (with sulphur crystals) not a candle.

Many thanks OT1!
Sadly the sulfume is a bit pricy for my budget.
Sorry to be so daft but is Essence a product?
I google it but couldnt find...i will keep checking for it anyway
I def dont wanna to contaminate my smoke
I´m gonna try a homemade brew of fish emulsion,garlic and mineral oil.Do you need will help my plants?
Thx again for your advice
Peace

Sorry OT1, is the essence the one from Plant Magic?
I grow on CannaTerraProPlus with the exception of 1 Cannaloupe on JInnes3, would essence work on those?
Thx again

Yep, its not simple to use but it works.

Essence is sold by the good folk here at Plant Magic. Click on their banner, somewhere on this site. There are also topics here on how to use Essence.

Thx Rand
Let´s see how it all works. The grower learning process is a must

Peace

Checking those right now!
The question is why didnt i find those before!?!?

Just to say I had a meeting with plant magic yesterday as we have been collaborating on developing their organic fertilisers. I had assumed essence would control mildew, but having never had powdery mildew, never tested it, anyhow it came up in conversation that sales of essence were up in some areas, feedback from shops was that it was being bought because it was controlling powdery mildew to a point that it was subclinical. It seems in some areas of the country leafspot is rife and in other areas powdery mildew is becoming a big problem.

FWIW I've only had 1 questionnable case of LSF, but ongoing autumn/winter powdery mildew probs down here in the south. My black violas outside showed powdery mildew about a month ago, but it hasn't established inside yet.

I use AN Protector (Potassium Bicarbonate) which makes a very alkaline spray which kills the PM on contact but doesn't appear to be anywhere near as systemic as Essence. Cheaper options are to produce your own very alkaline spray, e.g. diluted milk, but better to get a product and sort your air exchange imo.

Good luck with it - PM is a bitch but like anything else it is cyclical and the key is breaking the cycle. Whatever treatment you go for, make sure you repeat it for about a month to ensure you've killed the cycle.

I´ve never ever seen mildew in england until last Spring, maybe is the oh so danger global warming helping out the PM
I´ve sent an email to plant magic and maybe i will give it a go with essence, just placed a order with them last week if i only knew it before

"bayer systhane fungus fighter" is the only thing thats EVER got rid of PM for me, i dunno if you can use it in flower (infact i wouldnt use it on owt after say 3weeks 12/12 and not touch any budsites with it just incase).

never used the plantmagic gear so couldnt comment

Yeah, but that stuff is really nasty....a last ditch thing when absolutely nothing else works, and even then I'd think twice about it.

GN

you sure GN it says safe for foodcrops

It is used on food crops, why would that make its residues safe to smoke? From one spray to full decomposition in the living plant tissue, takes a minimum of 13 weeks and up to 31 weeks.

greenninja, ot1 cheers for the heads up fellas ive had a little lookysee about and yup it aint nice stuff . into the shed it goes for the garden.

the emails have just been sent out to the lads who told me about it (a lesson ere for me.... look shit up tit )

i've got a shit load of white powdery mildew on my durban poison outside....it's late finishing so i'm gonna make hash from it. read somewhere that water/ice extraction will separate the mold spores to float along with the leaf material leaving the good stuff at the bottom.

For powder mold/mildew try Green Cure. You can google it and it comes right up. This stuff rocks for powder mold. However it doesn't work that well on brown/grey molds as it suggests.........

You aren't suppossed to spray this on buds only leaves....FYI!!

Thx Trebor for the input.
I´m not a big Bayer fan, if you know what i mean, and the most affected plants are now finishing the 6th week of flowering so dont want anything toxic.
I think i will try the essence but many thanks anyway.

Peace

Hi there silverback!
Thx for the visit.
I got the some plan as you with the only diference that im thinking more a Quick Wash with some good quality ISO alchool
I guess that the alchool will destroy the damn spores, dont you reckon?
Thx again for the input

Peace

Hi Yodel!
Thx for caring
Im gonna check the Green Cure right now. It´s good to have options.

Peace

Greencure is again Potassium bicarbonate and a little bicarb I think you can get Potassium bicarbonate for about 15 quid a kilo here in the uk and bicarbonate of soda at any corner store for pence, thing is do you want these residuals on your plants, I know they are safe to eat fine on veg and fruit but burning is another thing.

Thx again OT1.
Btw if i decide to make some hash with my contaminated plants what would be the best method of destroying all the spores stuck in many of the resin glands?
I was thinking of making a Quick Wash with a good 99,8%ISO Alcohol...Any sugestions or advice?
Thx again
