Damping off, Stem rot....Treatments?

[Scrogerman]

Edit- Maybe Physan would be a good fungiside to use but not for your Res, ie- applied to the infected area & not dumped in your Res!!
i thought that Physan 20 was for solution(In Res) use only but i dont think thats quite right & can be used as an external treatment also.
After reading the product info on their site its actually made for treating 'damping off', best get myself some then, cool! Im sure its banned for sale in the UK but i cant see why as it seems like its not toxic to us if used at the recommended doses. Anyone know why its banned in the UK? or have i got that wrong! G'Luck with it!!

Sounds to me like you got it from the thrips and not your methods.

why would thrips cause stem rot?

 

[PuReKnOwLeDgE]

About to wake up the girls, lower the water, digout some hydroton, I purchased 4 huge floor fans and I am going to blast them. Also got some physan 20, hoping it is not needed....

why would thrips cause stem rot?

They carry disease and weaken the plants immune system. I just lost my first few clones in years from a mother that had a thrips problem. Sprayed with sinosad and waited a week to clone but they rooted.

thanks for the input JF

I just spent a few hours with the ladies, accessing the situation, and hopefully making some ground.

I think this probelm started, when I filled up the netpots the rest of the way around the base of the plants. Almost a perfect line of black where the hydroton was. Below the hydroton most of the infected plants are in good condition. Out of the 24 plants, I would say only 2 are showing negative signs from this, and I would say 12 overall have signs of this already being present.

I emptied the netpots pretty far down, removed all the branches and leaves hindering air flow, and I added 4 35" floor fans between every other row. I tied all the plants up that needed it from hydroton removal.

Then I mixed a quart of water with a couple drops of physan 20, mixed it up, used cotton rounds, and dabbed it around the heavily infected areas.

More aquashield was added to the system, the roots are 110% great.

I will report back in a few days or when i see some changes.

BLEACH! PM Krunchbubble ASAP I believe he had a similar issue.

 

[PuReKnOwLeDgE]

thanks IDO, the roots are perfect, and the stalks are no where near being in the water, the hydroton all around the infected area was dry, not even damp...

I think it may have "stemmed" (drum roll please) is some leaves near the base of the plant getting buried in the hydroton, causing mold and rot...At this point I am hoping the dabbling of physan 20 I used has no negative effects, and I honestly cannot see any mold or fungus enjoying the wind beneath the canopy I have created.

I can only hope....I won't know if it helped or murdered them for 2 days, I can't make it back over there until then. I am hoping when I get there, the stems are dryed out. The sour bubble plant is hardy, and I may have caught this just in time and reacted appropiatley. Will suck to have to start over, would mean it would take 19-20 weeks to get a crop through the room....

I will update with photos as soon as I get a chance, you would be surprised at how good they look, only 3 have the fuzz, the other infected have a little black lines. The nutrient solution is FULL of aquashield, I don't see anything happening below the trunk.

!!!- thanks, I pm'ed krunch last night, simply because when it comes to annhilating shit, krunch knows whats up. I don't suspect anything needs to be added to my reservoir besides aquashield, everything is happening outside of the solution.

thats good but running the system u do u might wanna check those things out just to see if they could save u some money nomore airstones save money on electric less cords and hoses running all over the place,,,good luck with ur troubles brother,,,peace

 

[PuReKnOwLeDgE]

right on IDO, I was checking something out earlier based of magnetics and pythium, crazy shit.

I just read on some gardening sites, that cinnamon and sulfur can be used to heal wounds on plants, they are both natural anti-fungicides. Crazy shit, I have a couple wounnds I wouldn't mind healing.

Smoking some outdoor sour bubble, my mocha pheno, shit is intense! I compare it to a "grill cheese" high. Def a pain reliver/muscle relaxer.

Excellent find bro. Another reason to clear that underbrush

Honey is a natural antiseptic along with aloe which can safely be used on plant tissue. Get you hands on plant tape as well. Its very porous and allows the treated area to breath under and through the tape..

 

[Scrogerman]

Hey PurpleK,
So you wouldnt go with the 'Scrape it out' idea? Honestly mate if you catch it early enough before its eaten its way too deep into your stems, it does work, Id say ive scraped it away at least 3 or 4 times over the years. i was hoping it helped some! GLuck anyway !

The bacteria in honey doesn't affect our plants? I know you don't give babies under a year honey because of the bacteria. Maybe bad for the plants when they are very young?

Honey has 2 major properties
http://www.honey.com/nhb/about-honey/
1. It's hygroscopic - It draws out water.
2. It's an Antiseptic - Kills Bacteria.

Its a debatable topic I know and I'm not looking to get into it brother but the wickng effect honey has may play a beneficial role in the removal of moisture from the affected area. On the other hand the affected area will see a rise in bacteria because it is in fact somewhat infected and the honey will prevent further bacteria from colonizing.

Its indeed a home remedy and may not be applicable for this situation but it will not hurt the plant and anything to help the OP is my aim.

I found a great link about sclerotinia, stem rot. Its an article from University of California.

http://ucanr.org/freepubs/docs/8042.pdf

I have also found a product called Phyton 27. Its a systemic fungicide that should kill sclerotinia, but I can't find out how long it lasts in the plant. There are no edible plants listed on the label, but it might just be for liability reasons. Personally, I would want to know exactly how long it takes a plant to get rid of it after an application. I think any systemic product should be used in this manner, as to not have any in the final product.

Surface stem treatments will only kill the fungus on the surface. Sclerotinia invades the tissue of the plant, the surface is just the entry point.

 

[Scrogerman]

Honey is 100% Sterile & contains No Bacteria whatsoever, as far as i know!(wrong)
Good for treating Burns (as they used to before modern medicine) & wounds. Oh sorry just read that some types of honey contain beneficial bacteria of the Lactobacillus and Bifidobacterium types, this originates from the Honeybee stomach. I never knew this. always thought it was completely sterile & bacteria free, well, you learn something everyday!

 

[Sam the Caveman]

Did a little bit more research on Phyton 27, and in the faq section on their website, they say it is safe to use on fruit bearing trees that won't bear fruit for at least a year. (= not safe for cannabis)

Phyton 27 = bad idea for cannabis

Thanks everyone for your advice, help, and information. I will be checking the girls tonight at lights on, I had to leave town for my 5th anniversary with my gf. My helper who kept the system stable for me while I was gone said the rotted spots look all dryed up and they look like they are throwing bark arund the wounds. Keeping my fingers crossed!

 

[PuReKnOwLeDgE]

Upon checking tonight, the plant that was hit the most was dead, the rot reached the center of the main stalk. Two other plants remain with a small amount on them, if they are not dry tomorrow I will apply physan 20 the the spots. All others that were of concern look to be almost 100% solved, the black and white shit is gone, fans did there job. Not out of the water yet, but hoping for 100% recovery of everything still alive in there.
