Mosaic Virus in Cannabis pics

[mark6699331]

The best resource if you can find a copy, has been suddenly taken off the market, is Robert Clarke's Hemp, pests, diseases, etc. It retailed for 100$ but is going for up to 400$ a copy if you can find one! Amazon only had three available last i checked. He hints that it was engineered for canna. Also, btw, he states no none cure. I have been doing immense research, and on the verge of a cure not available in the USA. Hope to distribute soon. That's all i can say for now.

 

[DIGITALHIPPY]

i agree
ive seen the same things in pics 2 & 3 in this thread: https://www.icmag.com/ic/showthread.php?t=193105




^^^^ very much tmv in my opinion. unfortunately. i am of the opinion the root aphids carried it from the Chem D to the affected plants. unfortunately.



!!! - had root aphids or other pest recently ?

thats VPD (vapor pressure differantial) problem....
poor environemnt.
not enuf hunidity, spacificly.

You physan people. Try with one pos. plant, not the whole garden. Physan with saturater or a dmso type material in low does and watch for phytotoxity. That answers "greenmofos" question about a aids person taking a bath in aids drugs. Yes if you bathed in aids drugs with dmso in the bathtub and it didn't kill you, it would kill the virus. Problem with aids like TMV and other protein coated RNA viruses and this one, in particular is tricky, as it turns of the i may be wrong, but the certain cells that tell the immune system it is even sick. SO the human or plant is totally unaware it is being under attack so it doesn't retailiate. In Clarke's book he explains the early pistil browning. THe virus causes early sensensence, (pistil browning early), dwarfism in plants, less cholorphyl production (those blister of infected "hijacked" plant cells used as replicaters for the virus instead of cholorphyll production.
If your plants survived, the toxic physan, which the people who make it i emailed, assured me if was PERFECTLY safe for edible products for humans. Muaaahahahahaha! A benzene based molecule!!!
Anyway this is real, it's spreading like wild fire in norcal. Get ready folks. Now that the seed stock is infected too,, and no official cure, hmmmm boy are we in trouble huh?

 

[mark6699331]

Oh the chitolisan meantioned earlier from crab shells- it doesn't kill the virus but interfers in the soil nematodes life cycle that act as a vector for the virus into the roots of the plants. Hopefully you don't get stem systemic nemodtodes as there's no know cure for those atm.
So that's why some soil co's put crab shells high in chitlosan in their mix.
Point two- sativas seem to be affected the worse in flower. REason is it takes longer for the alkaloids, thc, thv, thg, cbn, cbg, cbcs' etc etc. to form- at least a week or two. Incicas start after just 2-3 days. Well in reading Clarkes book and some references to canna alkaloids curing/killing MRSA i also read it is not only a great anti-bacteriicide and turmor killer, but an EXCELLENT VIRICIDE. If you could systemically spray each cell with THC it would kill the virus. THat's why the virus supresses thc and alkaloid production in flower and does early sensesence. Just enough to produce seed to continue the virus life cycle into the next generation. So yeah, plants with early high alkaloid production (crystals for newbies) will inhibit the virus from totally taking over the flower cycle and seem not AS affected as sativas and 50/50 crosses etc. Hope this helps. The trick is to use a physan or the zone/ie sodiumcholide cl3 molecule systemically via dmso or saturater without killing the plant. Keep in mind, all the hijacked viral cells will die! SO if the plant is 90 percent infected those 90 percent leaves will die overnight. THe other ten percent will probably not make it on thier own. Like with chemo in humans, the trick is to slowly kill of percentages of the infection without phytoctoxcity dosages to high, slowly over time, just like chemotherapy in humans. Kill the disease but just short of killing the person. So it's a build up the immune system of the plant and simulatainously kill slowly the infected cells over a months period so you don't just kill the plant overnight. It's all about balance and your in a chess match with an evil genius virus (ironically, that isn't technically even alive!). No sleep for the good people. When i import my cure, after the mass spect and gas chrom. arrive for our doc approved lab etc., permits, all that jazz, i'll let you know when i can market the cure i found. Different from what i've put here and from what other locals told me. It's herbal based and requires no fda permit. Maybe the sbay might sell it. If not, well distribute it somewhere. I studied chemistry and physics for a couple years in college. If it's the last thing i do before death, i will cure the scourge of viruses, from plants, to flv in cats, to herpes in humans, etc. IT's basically all the same, just different, protein coats, rna stragegies etc. ANyone finds good results please pm me. I'm testing strategies for legal clubs in cali where we can do this legally on small scall testing. Cheers y'all.

good luck mark... hope you do find the cure it would be sweet..

So has anyone completely culled the TMV on your plants? If so, what did you use, how many times?

I used eagle 20/ physan 20 to treat it, along with less intense lighting while vegging for longer and it seemed to have positive effects.

I have noticed that the indicas are definitely more resilient and show less symptons.

mark6699331 what are you testing now?

 

[Billygoat]

Well, it looks like I'm having the same issues as others. I've been having issues for some time, but I thought it was from me being out of grow for a few years. I've been beating my head against the wall trying to figure this out. Got everything perfect in my rooms and plants grow good and healthy, but when I flip them. BAM! Some, I'm my clones have show same issues as a good amount of those pictures posted.

This year has been one fucked up one for me. Three death's in my family and now I find out I've got a virus in my garden. Man, things keep getting good for me.

Thanks to everyone with all the info and pictures. I would have never figured this out with out you the members and IC. I'm going to order the test kit and see what that tells me. Thanks again and take care.

[lilmiss]

Great fucking thread dude! And props, this is what I believe my plants had. Leaves looked the same.

Wonder why he was banned?

Ok, I'll go back and read further.

 

[Rmor1551]

After reading this thread and countless other sources for the last few hours, I'm still not at all convinced that these "symptoms" people are talking about are not just leaf variegations and simply part of the plant's genetics. This plant has been inbred countless times over the years. Variegation is very common in many plants and has no ill effect other than the slightly decreased photosynthesis at the actual variegation. Infact it's prized by breeders of certain plants. I've seen this on many of my plants over the years and also like everybody has been saying, it's more pronounced when the plants are stressed. I had a Salmon Creek that had a very strong variegation (looked like everyone's pictures of "mosaic") and it was a massive yielder. I have an ATF that is also a huge yielder of very potent meds and it has a variegation...

Thanks PureKnowledge. You stayed very true to your name and got the test strips to prove there was nothing wrong. My salmon creek looked very similar in coloration as the photos of your bogglegum. No issues, no hermies, just giant stinky colas...

None of this is to say that the TMV virus does not exist in cannabis. I just don't think people should panic and immediately scrap their garden because a varigation showed up...

 

[ItsGrowTime]

Ive been growing a strain exclusively for the last few years and it's had the mosaic virus (or something similar....same issues as the first pages pics). It only causes issues during flower and it definitely will burn up leaves. The yield is has still been ok and the end product is great so Ive stuck with it.

Now Ive built out a large vertical lighting space and the plants just can't handle all the light from the bare bulbs and the leaves are more affected than previous grows. It's a nasty virus and it stays with your plants no matter how many cuts you take over years and years. Ill probably have to ditch this strain now.

Here's some pics of affected leaves in stages. Not great pics but the virus manifests a lot like a calcium deficiency that you can't fix. Same circular spots that start at the tip. I have the feeling that the virus basically messes up calcium metabolisation.

Stage 1

Stage 2

Stage 3

Good post

 

[Love2herb]

Just put in my order for 5 tmv test immunostrips gonna see if the og fire and chem dog crosses I've been growing have it. Don't want to bring more ladies into the garden until I know.

 

[bongslyde]

i wonder if the mosaic virus and the other plague virus the one that destroys the buds from the bottom up dries out the hairs an has a powdery mold sheen are two different viruses .i had a original chem from nyc that had the leaf deformities and all ,that grew great for years,it was the best shit , then someone gave me some clones that had the funk, you know who you are. an all hell broke lose plants dyeing from bottom up in 4th week of flowering when plants wilt they develops a dusty yellow gold mold . so the thing is people that think they got mv an are like it really dosent affect the plant,,,,,,,but with this other thing virus you would be like o shit this thing is wiping out my crop..

 

[compost]

When I have had problems like these in the past I always associated it with PH/to much nutes. I have been lowering my soil PH the last few weeks and have had a lot of those problems. I had this happen to me one time before also. I had given my mom way to much nutes. The plant kept growing and new growth a few days after a regular watering was back to normal. Never saw it again in that plant.

I had some GHS seeds recently and all of one type displayed the curved multiple color leafs. My basic assumption was just seeds that were on the very sensitive side and couldn't handle much variation.

 

[Love2herb]

The plant I tested shows negative. Wish I had these test last grow cuz that's when things were looking viral. Stoked about this grow now!

 

[FRANKIE1579]

I'll throw my two cents in. This virus is real, and it is out there. It is decimating people up in Nor Cal as we speak. I am one of them.

I am no master gardener and no expert, but I have been in this game for over 10 years, and pulled consistant indoor yields using the same methods, and have never experienced this.


I made a mistake and donated 40 large teens to a collective that I did not think I needed. I run multiple rooms and areas and I was expanding and made an unfortunate miscalculation.

One week later when I realized my mistake, I figured I would rectify it while adding some fresh genetics to try in a room. I purchased 40 Purple Candy Teens off someone. They were not very healthy looking due to overcrowding, I am (was) fairly confident in my growing skills and did not see anything I could not rectify very quickly. It seemed a good deal so I added them to my veg room, along with my own strains of Dream Queen (Green Crack) Blackberry Kush, Jack Herer, GDP, NL 5, an unknown kush that people love and yields well so I have kept, and my pride and joy Superfrost.

The purchased purple kandys had the same symptoms I now have all over, except to a far lesser degree. (A leaf and growth tip here and there). That is how I know the means it was introduced in my garden, I saw the problem on them, but did not correctly identify it. (I believed it was a cal-mag issue, as so many people incorrectly assume and wreak further havoc on their plants)

Over the period of two weeks those initial symptoms got worse and worse, all new growth from the infected plants had blistered, twisted growth, with brown tips. Nothing I tried corrected the issue. Flush, light nutes, heavy nutes, cal-mag, epsom, you name it, I tried it. 5 plants each out of 40 were given seperate treatments. So 8 different regimens/tactics/cures. All reacted in the same manner, which was to get progressively worse.






In disgust and slight worry, I began to research online and ran across the tobacco mosaic virus, and its many other variations. I immediately removed all of the purple kandy plants outside, and placed them in a safe area. I was still unsure at the time what I had, but knew it was something I had never dealt with before, and did not want it spreading.

I thought I was scot free, with a good lesson learnt. I run a perpetual grow, with 180 plants vegging. All veg plants are sequestered together at different stages of growth. They then are moved to the muliple flowering rooms, where I pull a harvest every 7 days, and on the rotation goes.

I began to notice the same symptoms in my own plants that the purple candy had displayed. I saw one affected growth shoot. (necrotic pistils, twisted leaves) I cut it off, and sterilized the scissors. Next day there were 2. And several on the plants surrounding it. I checked closer. I found deformed/dead growth tips in all areas of this flowering room. With the plants that were put into 12-12 one week ago. And it is spreading.

I ordered the test strips for TMV from Agdia. I had a faint pink line on the positive mark on 4 samples. I tested the final 5th in clean tap water, to ensure the test was correct and I did not have a contaminated/faulty test kit. The 5th in tap water showed no positive line. Pretty definitive for me, but I will be sending a sample to Agdia to confirm and test for others to be 110%.

My veg room looks healthy,




I have extremely low temperatures at the moment and just built a new structure to accomadate the vegging plants, but neglected to insulate the floor, which I am doing tommorow. The plants do not look thrilled due to lower soil temperatures (55 F) but no signs of TMV in them at least. I will be raising the beds with 4X8's and pumping warm air from the lights underneath to create undersoil insulation. Anyway

I should add I do not have pest problems. I have dealt with spider mites, broad mites, root aphids, fungus gnats, thrips, I've been through em all and learnt how to handle them, they never last long in my garden. It's the graveyard where bugs go to die, so as a possible vector to spread the virus is not an possibility.

The logical thing to do would be dump EVERYTHING. Bleach, disenfect, and start over. However this is not an option. If I dump everything, I lose 4 months of cycle. That puts me into the ground, I simply cannot afford it with power and space bills. So I have to beat this with the plants I have, or I lose everything I have worked for, simple as that. I also WILL NOT lose my superfrost genetics (not jadesuperfrost). This is a 40 day flowering strain, buds have dark purple hues and so covered in resin you can hardly see plant matter. I went through absolute HELL to get this genetic from the breeder and only 2 other people have it. If I lose that I will be beyond pissed.

So I am coming up with plans of attack. For a start I will have to isolate the root systems of plants. It will lose me valuable space which equals plant amounts which equals production, but better some than all of it right?

I do not think I will be able to keep plants from touching eachother. If I do that I can only sustain half the plants and would be a massive waste of electricity and space. If I am being foolish here I would appreciate advice from anyone, because I am at damage limitation phase here. For now I will cull any plants that show signs of the virus and hope they do not infect the others.

Secondly I sprayed the plants with 325 mg aspirin to 1 gallon water. I am trying to boost the plants immune system and induce SA. I do not know if it will have an positive effect but it has not hurt.

I ordered Jaz rose spray

http://www.jazsprays.com/JAZ-Rose-Sp...trate_p_8.html

Jaz rose spray contains salicylic acid which is used to induce Systemic Acquired Resistance. I will report back on how that goes.

I have also boosted CO2 levels in flowering. There is alot of misinformation out there but it seems to make logical sense that a healthy, quickly growing plant will fight off a disease better than a slower growing one. So CO2 levels are going up to 1000 ppm from 600.

I have been reading SO much the last few days, so I apologize for not being able to cite sources, but products which I am considering which people mentioned having a positive effect are

Eagle 20
Physan 20
Barricade
Scorpion Juice
Wet & Forget (Vaccinate)

I will be testing these products on control groups showing signs of the virus and hopefully will see improvement from at least one.

Things I have learnt first hand from the spread of this are

1. It can be spread through direct contact (plants touching)
2. When you see signs of it, burn that fucking plant immediately before it spreads.
3. Never buy clones from someone you don't know extremely well and have faith in their knowledge/growing experience and honesty.

ANY advice the experts or people who have experienced this problem can offer me I would love to hear. I believe this can be beaten, not gotten rid of, but controlled, which is all I need. The reason I believe this is that the purple kandy plants outside ARE still alive and green. Yes they look like shit. But they are in conditions where it gets 38F at night. And they have been drinking only rainwater. But they are still growing, albeit slowly.

If they can survive, surely my babied plants can produce?

Then I can slowly introduce healthy unaffected genetics into my garden over time without suffering a 4 month loss of production. I am not someone who gives up easy, but I realize what I am up against so I am under no illusions. I am holding on to the hope that


A. I have a mild version of the virus
B. I keep my plants healthy, they might be able to fight it and still yield well.
C. That I have not suffered a mass infection but a localized one.

I might not get any of those, but those are my only 3 rays of hope atm lol. Like I said people, ANY advice is appreciated

 

[Zen Master]

well if ya got a positive result from the tests I can't argue that.... just doesn't look like the other 'symptoms' of TMV. So perhaps what you've got IS TMV while the other people just have some variegation?

anyone else get a positive result from their test strips and have pix of the damage?

I don’t think it’s a Mosaic Virus. I suspect your plants have a Tospovirus. Your photos look eerily familiar. I recently cleaned house because my plants were suffering like yours.

Problems started for me when I temporarily moved some plants out of my veg area to go outside in the short days of Fall, hoping to get a head start on flowering while saving $$$ on electricity by not firing up the flowering room lights. When I later brought these plants back indoors to the grow area, a population of thrips came along for the ride… dumb move on my part. When I recognized my mistake these plants went back outside, but the deed couldn't be undone.

The plants which went back outside never really developed much, with pitiful buds. I blamed it on the cold. I did get a harvest inside, but problems started when the next batch of clones went into the flowering room. Plants which had been doing well vegging under fluorescent shop lights stalled when placed under the bright 400 watt CMHs. Leaves developed an interveinal chlorosis until they were bleached white, with edges downturned. They became dry and brittle. All growth simply came to a halt. Some plants in the veg room started to show the distorted growth patterns shown in your photos. Then I discovered that I’d failed to eradicate the thrips.

Researching thrips led to info about the thrip-tospovirus connection.

All of the information regarding plant viruses I've found on I.C. forums relates to mosaic viruses, specifically the Tobacco Mosaic Virus. When I started googling "plant viruses" I found another world out there. The greenhouse horticulture industry is struggling to deal with Tospoviruses, which are spread by thrips. The big two in this department are the Impatiens Necrotic Spot Virus and the Tomato Spotted Wilt Virus. When I read this the proverbial lightbulb lit up over my head.

In the area where I live, people are having a lot of trouble with their tomato crops. I've seen many tomato plants that look similar to your suffering cannabis. A nearby friend is a commercial organic gardener, and his business has been decimated by the Tomato Spotted Wilt Virus. It is all across North America now. So I know the virus is affecting tomato plants in my town. That means there are thrips carrying the virus where I live. After bringing local thrips into my growroom my plants started showing similar symptoms. I don't think it's just a coincidence.

When this all came to a head I was in the middle of switching my grow from hand watered to an automated ebb and flow system to allow my plants to survive while I went away for a week and a half to assist a good friend having surgery. Recognizing that viruses were part of the picture, I realized that I could be on the verge of totally contaminating a new hydroponic system. So I tore down everything, tossed, cleaned, vacuumed, sterilized, and set off a bug bomb in the room before leaving town.

Thrips were a vector for sure. Whether or not my cavalier scissor technique while taking clones helped contribute to this fiasco is uncertain. I read one source stating that pruning does not spread the virus. I also found no references to fungus gnats doing the deed either. But seeing this situation it seems inevitable that there are tospoviruses evolving to better fit the cannabis growroom. The confined crowded environment and taking of clones seems ideal for propagating an opportunistic virus.

I hope this proves of value to someone. I'm glad to finally join this community.

Someone actually did a test on tomato plants and tmv. Certain plants they fed with dilluted sea water. The tomato plants that were fed dilluted sea water were immune to catching tmv. Sorry I don't have the link but just google and it will pop up. The other plants that were gave regular water and introduced to the virus all became infected. Not sure if this would work with cannabis but it's worth a try. We need to stop this problem before it gets worste. I've seen too much plants and investments lost to this here virus.
