San Diegos Finest Cuts #2

[guest396]

if i remember right, dragors chocolope smelled like fruity pebbles....but it rocked....

i ran choc in my last run of 09 all the leaves on it and big kush (cush subrob) turned completely black. nice smoke. one of if not my first jar(s) gone.

looks like surgery was a success, good thing it happened after all they had found a polyp while in there.........non cancerous.

ohgee's first run of SFV OG is coming to an end in around a week or two... stoked.

ive been burning sulfur for a couple years.....krunchbubble (and others) turned me on to eagle20 and since 1 single application...i dunno...4-6 weeks ago... i have not burned sulfur once and have not seen even a hint of pm.....i will never again be without both(til something even better comes along anyway)

Yeah that Eagle-20 works great but it's not perfect. If a plant has had PM it's shows it's susceptible to it and there's spores in the enviro. I had the PM come back at about the 2 month mark after using Eagle-20 and a friend had a similar experience. It sure does knock it out of the plants though.

After a few years looking into PM I think it's a variety of things such as enviro, genetics and nutes. Canna needs a lot of calcium and PM puts out pectolytic enzymes that basically dissolve the structure of the plant as the PM spreads inside plant tissue. Calcium instantly deactivates the pectolytic enzymes. Just a part of the puzzle.

Odd question... What makes you think PM is inside the plant tissue? Everything I've read says the mycelium from PM grows on the plant surfaces but not in the tissue... Do you have a link? I love learning new things

Do you think calcium might work due to the fact it adjusts pH? Just like baking soda, bleach, lime, and sulfer do...

After spore germination, the powdery mildew fungus grows on the leaf surface and sends suckerlike structures (haustoria) into the plant's epidermal cells (cells in the outer protective layer of plants) in order to obtain nutrients.

That's a start.

I just want to know if the PM we have is epiphytic or endophytic?

http://www.apsnet.org/education/labexercises/powderymildew/top.html

Unlike most fungal pathogens, powdery mildew fungi tend to grow superficially, or epiphytically, on plant surfaces. During the growing season, hyphae are produced on both upper and lower leaf surfaces, although some species are restricted to one leaf surface only. Infections can also occur on stems, flowers, or fruit. Specialized absorption cells, termed haustoria, extend into the plant epidermal cells to obtain nutrition. While most powdery mildew fungi produce epiphytic mycelium, a few genera produce hyphae that are within the leaf tissue; this is known as endophytic growth.

http://edis.ifas.ufl.edu/pp109

The fungus produces specialized feeding structures called haustoria that invade host cells to extract nutrients. The removal of nutrients from host cells causes the yellowing and eventual necrosis of tomato tissue. The plant is not killed by this disease, but is progressively weakened and productivity greatly decreased.

That's a start.

Thank you for your time....

Powdery mildew diseases are caused by species of fungi such as Erisyphe, Leveillula, Microsphaera, Podosphaera, Odium, and Sphaerotheca, although each powdery mildew is specialized to infect only hosts in one genus or one family. Infection does not spread to species of plants in other plant families. Erisyphe has a wide host range and can infect many plants in the Asteraceae family, while Sphaerotheca pannosa var. rosae is confined to roses.
The distinctive whitish powder on leaves is composed of fine threads of fungal vegetative tissue (mycelium) and light colored mats of asexual spores (conidia). Some Powdery mildews produce conidia on short, erect branches that resemble tiny chains, while others form threads so sparse that the mildew cannot be seen without the aid of a microscope. These spores are easily moved by air movement and water splash. Because Powdery mildews are obligate parasites, they do not require plant stress or injury to infect plants. When spores land upon a susceptible host, they germinate and send a specialized feeding structure into the epidermis and obtain their nutrients from the plants. The infection process may take as little as 3 days or as long as 7 days. The pathogen survives in the greenhouse in weed hosts or on crops. Outside, the pathogen can overwinter as mycelium in infected plant parts or in resting structures (cleistothecia) produced by sexual means and visible as small, dark specks on dying leaves. Powdery mildews, unlike most other fungal diseases, do not need free water to germinate and infect. They are favored by high relative humidity (greater than 95%), moderate temperatures (68°-86° F), and low light intensities. The disease is more prevalent in the spring and fall when large differences between day and night temperatures occur. Temperatures above 90° F kill some Powdery mildew fungi and spores and the presence of free water can reduce spore germination.

This may sound silly but... I've been waiting for the summer heat, and it never showed... The true reason I got the damn burner LOL

Interesting info from your link Mitochondrion.

Unlike most fungi, powdery mildews only colonize the surface of plants making chemical eradication possible. It is not necessary to use fungicides to prevent Powdery mildews. Fungicides with the active ingredients propiconazole (Banner Maxx), myclobutanil (Eagle, Systhane), triadimefon (Bayleton, Strike), fenarimol (Rubigan), thiophanate methyl (Cleary's 3336), potassium bicarbonate (Armicarb, MilStop), or sulfur are registered for Powdery mildew control on ornamentals

The Powdery mildew fungi can develop resistance to any of the fungicides, except sulfur, listed above so be sure to alternate fungicide applications among chemical classes.

That I can't answer. Chimera seems very knowledgeable when it comes to PM so maybe try over in his section here at IC.

http://www.icmag.com/ic/showthread.php?t=129670

I agree with Chimera in that I believe PM can become systemic in canna. That might answer your question or at least from my perspective.

I got some cuts from a friend from the San Jose area a few years back. I thought they were clean but had PM. I turned them over to a few friends and the problem showed up pretty quick. One friend has been growing indoors and out for 35 years and remarked how the strain of PM I gave him...ooops...was different and tough to deal with. He called it Super PM...lol.

I do not agree with Chimera about that... But assholes are on everybody LOL I guess its all in how you want to the picture... One study says this and another says that...

I was introduced to PM by NNCC in the SFV with the Dabneys Blueberry and Afghan Kush... And Santa Barbara made it stronger LOL

I think calcium works but for other reasons that are just experience based and gut feeling related......ie; just too stoned to go into it....

 

[barth]

Lots of good info here all. Thanks.

 

[medfinder]

sour fornicate..

sour fornicate..

OK.... as promised.


heres some pics.

The first pics are of mtf x sour bubble 4 = Sour Fornicate.

this is the only 1 I have popped.

The white film on the leaves is Daconil fungicide

Her she is 32 days into flower... I took 5 clones off her and there starting to root..

Sour Bubble 4 male x Matunska Thunderfuck = Sour Fornicate.

 

[Dr.Diddy]

lovin the matanuska cross! looks good! keep up the great work SD!

 

[subrob]

420247-love outdoor pics! very nice! ya medfinder! that sounds like an awesome cross!...love new stuff...obsessed by it really! just found out there gonna be a new cut floatin outta pnc shortly! one ive been lookin for for quite some time.....course...i already got plans to cross it! haha....we are kinda slowing down on the pics here....ive got some in begining of flowering right now....will have pics soon...how bout everyone else? im calling ya out sd....lets see whats going on!

 

[praisehim.]

medfinder- NOW that looks promising. sour fornicate.. NICE.

 

[Jalisco Kid]

The BP is at about 68 days with a 13 day flush, the leaves are still purple black. The other 2 have just met their fate. JK

Enjoy

 

[Natagonnaworrie]

whoooooiieeeeeee...

thats looks dank. nice sparkle on those nugs sir.

Quick question. How's the stretch on the Headband? I'm worried mine is going to be out of control.

Although i stepped in some real shit by trying to run way to many strains at once i think.... or not.

Nice nugs 420.
