Thought this would be an appropriate thread as many seem to suffer from its affects. I have used a product from BASF with some success called Meltatox. Was also given the link below to another very good product. Peace GS

10% seawater

10-17-2008, 04:44 AM

Powerful Dehumidifier, intake filtration, adequate ventilation, preventive sprays and a prayer.
cheers

When i used to grow in Montreal, there where a lot of Back Alleys with small gardens all along that can be a mile long and everyone plants their Vines along the fences of the alleys....
Major severe source of powdery mildew for city growers...

Hi Canny.

Does sea salt in water have the same effect?

c-ray · 10-17-2008, 12:35 PM

10% seawater = 3600ppm

10-17-2008, 05:55 PM

holy shit!
Thanks c-ray

The Cannarchist · 10-17-2008, 06:40 PM

Strange as it sounds my plants never bat an eye with 10% seawater solution.
I let them dry for an hour or so ,then spray with plain water to wash off any salt residue.
I do this once a week and the plants are fine and seem to pick up a greater immunity to disease and pests.

I once used 50% solution and it did fry the leaf margins but the plant survived it.

you can hardly smoke that stuff.,.,.,.,

10-17-2008, 08:14 PM

The washing off spray you perform is probably vital to the process...

spaceman · 10-20-2008, 12:14 AM

sea water on the pacific coast and the atlantic coast differ in salt concentrations quite abit take this into account.,.,

Loki · 10-20-2008, 07:42 AM

I've had 100% success against powdery mildew with garden sulfur WP. A few years back I had a serious fight with PM. I started spraying sulfur as a prophylaxis one week into the 12/12 cycle. It prevented a major infection long enough to reach harvest every time. If spraying becomes necessary later in the cycle, I've found sulfur to be safe up to four weeks from harvest with plenty of rinsing. Beyond that, you risk ruining your crop by making it taste like rotten eggs. A mild solution of baking soda will slow powdery mildew down a lot, if control is needed in late flowering.

Janosh · 10-20-2008, 11:24 AM

Sea water difference.
Ok, will you elaborate more on the seawater. which has more salts Pacific or Atlantic?
I really appreciate this info. I'm on Lower Cook inlet just above the Gulf of Alaska.

The Cannarchist · 10-21-2008, 12:38 AM

Just give the 10% a test on some fan leaves with PM Janosh.

Nothing ventured nothing gained!

spaceman · 10-23-2008, 02:09 AM

i think the range of the pacific is around 1500 ppm
and the atlantic around 3600 ppm this is from memory .,.,,.

Average seawater salinity worldwide varies from 3.2% to 3.8% (according to my friend's fish)

spaceman · 08-18-2009, 07:05 AM

Salinity and temperature

Depending on the stage your plant is in you can use some fairly safe home remedies on the grey ghost.If still in veg a high PH (8.4)water spray may help as the mildew prefers a lower PH.You can also use the garden sulphur approx 1 tsp mixed into a litre of water and shaken up,then spray on leaves.Later rinse the leaves off well.I`ve found this works very well,you just can`t use it after flowering starts as you don`t want to smoke sulphur.Cinnamon is a natural fungicide and can be sprinkled directly on the mildew,or in water and sprayed on the leaves.
If budding has started a 4-5% bleach water solution can be sprayed on the plant without leaving any residual taste.
Then of course there are many fungicides that can be purchased at any garden center.I prefer not to spray chemicals on my plants,but that`s a personal choice.All I know is mildew can make your fuckin` life miserable.I don`t fight it anymore,just finish out the crop and do a thorough cleanup,then start fresh with seed or clones from another grow.

Peace

spaceman · 09-21-2009, 09:06 AM

so if PM is in the planties on a cellular level do things like peroxide, lemon juice etc,really kill pm or just beat it back.,.,if so how does this effect the mechanism in action?..,npk etc,
I am thinking fungicides used correctly.,.,,I know spraying every 3 days is shit especially later in flower .,.,.

I'm in the midst of one of the worst infestations of PM I've ever had to deal with. Nothing is even slowing the shit down. A friend of mine gave me some of this stuff (Meltatox). How toxic is it? Any idea? I'm about three weeks into bud, and It's looking like I may lose the whole crop. I don't want to poison anybody, though. Will it break down in the five or six weeks left in my cycle?

Green Supreme · 01-07-2010, 11:09 PM

I think it has a 3 week residue. Peace GS

01-07-2010, 11:28 PM

Systemic fungicides will save your crop. However, i am not sure about the systemic half life...

I have used NOVA in the past on clones with great success o an extremely susceptible strain.

GS have you ever heard of it? Do you know approximately how long Nova would remian in the tissues? It works wonders.
peace

Green Supreme · 01-07-2010, 11:47 PM

No sir I have yet to encounter that one, but have found that Purple Kush plants sprayed at 4 weeks will start to show signs of pm again before they reached 8 weeks with meltatox. Peace GS

01-07-2010, 11:50 PM

Cool, thanks for the feedback my man. I will do a little research and try to compare the two.
Peace.

Loki · 01-08-2010, 12:23 AM

Thanks GS. I'll give it a go.

	"In the uptake of nutrients from the soil food web, sulphur is the catalyst for carbon chemistry, boron gives us sap pressure and silicon builds the capillary action that transports plant sap. Only then can calcium, magnesium and amino acids be delivered to cell division sites for chlorophyll manufacture. As chlorophyll catches light, phosphorous transfers energy into sugar production—after which a mix of sugars and more complex products follow potassium through the silica pathways to provide energy or its storage wherever required in the plant."
