What's this?

If it is a type of PM it will work on trying to get through the upper cells where it feeds. The types I battle with seem to be non-systemic,and are a type that can't get deep into the tissue like botrytis. From there it spores out and spreads. I'd watch them carefully and prepare to observe any changes that take place overnight. PM can spread like mad in a few dark hours.

If it was a type of PM,chances are that the baking soda worked. However,if there were spores you now have spores hanging out waiting for the chance to find a spot to grow.

It's best to remove infected leaves carefully and with no air movement so you don't spread spores. Treat the whole plant with whatever organic method you've chosen. Under the leaves,on the stems,even the surface of the soil.

Organic treatments are typically only good for the existing growth,as new leaves come out they are targets for attack from that stray spore. Reapply treatment as new growth appears for at least a couple weeks. Spray the walls,floor,ceiling,fans,pots,everything.

Simple light foliars with Dyna-Gro Pro-Tekt work great on new growth as a preventative control. It must change the ph of the leaf surface as well as supply the cells with silicone for building stronger cell walls.....which is of course because silicone is one of major building blocks for strong cell walls....which then can better resist attack.

My comment about grapes was in relation to their resveratrol content which the grapes produce in higher levels (mostly in the skins) when necessary to help protect the fruit against fungus in very cool humid conditions like those found along the coastal PNW. Vino & primo!

Okay - now I'm convinced you're simply humping my leg and calling it a play date.

Run the term 'Bourdeaux Mix' (copper sulfate and hydrated lime) through your search engine of choice and see how resistant grapes are against a myriad of fungi.

Just for sh*ts and grins and such.

This morning Rhonda at KATU stated that this week the Willamette Valley will have 3 days in a row with temperatures above 70F and that hasn't happened since last September. 8 months ago.

Where are these strains that are magically resistant to PM anyway? Phoenix, Arizona?

Just curious.

well I imagine a looser flower structure would be less prone to total destruction?

I'm not even putting anything out this year.

That's just it,they are "resistant"...that's it. They all get eaten,but a few are stronger. I only have 2 or 3 types out of 20 that are. It's the thick leathery leaves that make them more resistant...or the wispy sativa structure works sometimes too.

Try growing squash or melons around here.

Best wishes!

Sounds like an opportunity for someone that can fix it somehow. Thars gold in them thar molds.......scrappy helpfull as always

There's this grocery store here that has some non-native decorative plants sitting outside it's entrance just loaded up with PM sitting there passing off spores to all the lucky patrons...except me.

I tend to agree on this one, I've got a NL#5 x Blueberry that has thicker leaves, and it is the only thing in my garden that didn't get PM this year. However, I have a Pandora's Box from TGA that is 70% Sativa, that just seems to have a love affair with PM.

 

[Scrappy4]

Serious here, for a brief moment anyway, wouldn't natural selection work? If someone could plant an area and just let the strongest most resistant types live on to breed. Or would that just take to damn long? I'm sure the state or the feds would not mind if we were using their land, as long as it was for science and all.......scrappy

I downloaded an eBook at the Project Guttenberg web site titled 'Indoor Gardening' and I was curious because I thought - Wow! A stoner grow book here?!?

As things turned it is a book written in the late 19th Century by a gentleman in England. The book explored the problems and rewards of growing plants in a greenhouse.

Guess what the 2 largest chapters covered? Fungi (mold is the term he used) and Red Spider Mites.

Natural selection probably wouldn't pick the pacific northwest as the spot for growing cannabis...


I think at some point we do have to admit that some regions are better than others for growing cannabis. The artificial scarcity caused by drug laws makes it more reasonable to grow in less favorable places, but there are reasons why certain regions become synonymous with certain types of produce.

and squash.

 

[guest2012y]

I'm slowly working on breeding types that are PM resistant and seeing if the offspring hold true.
In one seed group I had phenotypes that were PM resistant and other phenotypes that weren't.
It's really hit and miss at this point.

 

[Scrappy4]

Arn't those auto flowers from Russia? They have been bred into a resonable plant for human use. And Russia while big, does not seem like a pot growing mecca. I have faith the plant will adapt if givin enough time, and maybe some human intervention along the way. I seen in the movie "the botany of desire" how plants adapt to please us, so i don't think it is unreasonable, difficult? yes...........scrappy

How many generations have you done, with PM in mind? You are probably on the for-front capt C., cutting edge stuff.......scrappy

Just barely into the F2's man. Need lots of space and time.

true, but some regions will always make the most, bestest, easiest to grow pot, while others fight PM all year.

The obvious solution will be an organism which eats PM. One is Trichoderma [which I've yet to experiment with] Another is a high functioning bacteria(?) I grew in compost tea several years ago when using pyrophylitte powder as an ingredient.

That's the Space Queen in her. SQ is a frickin' PM magnet.

That sucks, cuz I love the taste of the Pandora's, but in the NW, the last thing I need is a strain the pretty much breeds PM on it own. I'm down to one Pandora flowering, and got rid of the rest of my Pandora starts. Way too much trouble to be constantly fighting PM with it, even if that cherry/lemon taste is so good.
