Tobacco Mosaic Virus WARNING!!

Just to let everyone in Southern California Know. The Tobacco Mosaic Virus is here.

Got slammed by this virus and it took someone from Holland to diagnose the problem, as no one locally seemed to know what it was.

It is transmitted from tobacco plant matter, where it can live for 50 years. Simply holding tobacco and touching a plant can transmit it. It is incredibly resilient and even bleach might not kill it. Once it is in your plants have it, it can not be removed.

You must wash your hands in hot soapy water, before handing your plants. Gloves are better. You must keep all dead plant matter out of your room.

Once you have it, you must discard anything that is cheap to replace and scrub everything else with pool shock treatment. This includes the walls and floor.

This virus doesn't kill the plants, but does stunt growth, deform and discolor leaves and reduce flowering.

I have attached some pictures to show what you are looking for:

You don't really know unless you buy a $35 test kit for it.

lol your tripping as if a plant cant recover, andmost all your plants immunities arent going to be low enough to contract he virus. i laugh at these virus threads, you need to do a little reading on pathology.

bacterial infections is where the real danger is, and even harder to get than a virus.

Let me just say a couple of things.

@nightmarecreature

Yes you can know if you have TMV, without a test kit.

Yes, this is very funny and I am "tripping". Keep laughing, because this is turning into a big issue. It is already hitting growers in Europe and Northern California.

And no, once you have it, the plants can't recover and it can't be cured.

The truth is that this is already a big issue for Tomato growers and they actually boil there dirt for 40 min between grows, to make sure that this doesn't get into their plants.

And obviously the clone seller thought it was a big joke, as he not only wouldn't let me in the building, but wouldn't get within 5 feet of me.

If you think that the TMV is a myth, you are talking out your ass. I just lost 3 moths work to this and am taking my entire system out, to sterilize.

The Tobacco Mosaic Virus is in Southern California, so laugh it up.

Isn't it alot of places besides tobacco? If they are boiling tomato soil, mj can carry it, etc.

Yea, it is transmitted through dead plant matter and through touching infected matter and then touching your plants.

It kicked my ass, as no one I spoke to knew what it was. Went through a second grow, with the same plants, before I finally posted a picture on this European board and they picked it out right away.

I continued to let the plants grow for another week, but all the symptoms played out. Distorted leaves, purple stems, growth without filling out. No green power.

So I dumped the whole lot yesterday. I have been running shock treatment through the system and tomorrow I will scrub it outside with more shock treatment.

Your plants can recover from TMV. Chem D has it and I have that cut. Spraying the plants with 1 tbs per gallon of Epson salt at 5.8ph. Put it in a spray bottle and foliar feed everday with the lights off. They recover if you catch it early before the yellow gets bad. For some reason they don't take in sulphur and it causes yellowing starting from the center and works its way out. I got it from some clones at a dispensary. It took me awhile but most plants recover. I'm currently working on tissue culturing to rid my keeper moms of it. Curved leaves and yellow veins are signs of it. There is no way to test for it. Those test strips will come out negative even if you do have it. There are about 5 viruses that marijuana can get. The only way to know if you have it is with an electron microscope.

If you smoke it do you die?

Not just once, but twice

if your spraying your plants with epsom salts to cure a fungus....im pretty sure your just treating a magnesium deficiency thats been misdiagnosed?

Ive seen people really make a stink over this virus, the only thing i can recommend is grow organic and supplement the soil with bene teas to get the microbiology working at full power. a strong healthy plant with a strong rizosphere that produces plenty of exudents can protect itself from alot.

cheers

Everything I've read says it cant be transmitted to Cannabis and no cases have ever been documented.

"Tomato growers are boiling their soil"... I think we can all stop reading at that statement and just assume this thread is conspiracy theory.

I can't be certain it's TMV but whatever it is, it does three things. It molts your leaves, it causes yellow veins on new growth or mosaic pattern and it causes the leaves to burn and bleach out under light. Whatever it is it's not grower error. I have tried every popular soil on the market, hydro, five different nutes, great white you name it. When I could grow just fine before with no changes, until I recieved these mosaic looking clones. Now things are hard. The TMV test kit will come out negative. I'd be happy to send an infected razor to anyone for testing.

I used an infected razor blade to slice my largest tomato plant. Guess what a few days later, extreme leaf motling.

Viruses rarely kill Cannabis. They only exist and replicate in living plants. Viruses can, however, seriously reduce yields. Once acquired, they are nearly impossible to eradicate. Viruses invade all parts of plants. Pollen and seed infections transmit viruses to subsequent generations.
Five viral syndromes are described in the literature. In addition to these naturally-occurring infections, Hartowicz et al. (1971) screened 22 common plant viruses for their ability to infect wild hemp. Over half the viruses could infect Cannabis.
The hemp streak virus (HSV) is frequently cited on fiber cultivars in Europe. Foliar symptoms begin as a pale green chlorosis. Chlorotic areas soon develop into a series of interveinal yellow streaks or chevron-stripes. Some-times brown necrotic flecks appear, each fleck surrounded by a pale green halo. Flecks appear along the margins and tips of older leaves and often coalesce. Streak symptoms predominate in moist weather, flecks appear during dry weather. Leaf margins become wrinkled and leaf tips roll upward, leaflets curl into spirals. Whole plants assume a "wavy wilt" appearance.
The hemp mozaic virus has been described on fiber cultivars in Europe and drug cultivars in Pakistan. Symptoms were described as a gray leaf mosaics. Three other viruses have been cited on European hemp—the alfalfa mozaic virus (=lucerne mozaic virus), cucumber mozaic virus, and the arabis mozaic virus. Many insects transmit these viruses as they feed from plant to plant. According to Ceapoiu (195, the worst vectors of Cannabis viruses are bhang aphids (Phorodon cannabis), greenhouse whiteflies (Trialeudodes vaporariorum), onion thrips (Thrips tabaci) and green peach aphids (Myzus persicae

McPartland, J. M., 1996. A review of Cannabis diseases. Journal of the International Hemp Association 3(1): 19-23.

Start from seed. Getting clones is risky business sometimes.

It always amazes me the "off the cuff" comments that people throw out here. Just so you can see, here is a description for the documentation on the virus, about control:

As a matter of routine, soils from which production plants have been removed, following harvest, should be steam sterilized before the introduction of new seedlings. Steam sterilization can be accomplished by steam or air-steam mixtures. In the preparation of soil for steam sterilization, sift it to remove clumps and large pieces of organic matter. The total soil mixture will have to be heated to a temperature of 200° F for 40 minutes. Since high temperatures are required, steam sterilization must be done in an enclosed system. Temperatures within the steam sterilization system should be monitored by high temperature thermometers to make sure the desired temperature has been reached. Steam sterilization of soil also will eliminate fungi, insects, nematodes, and weeds from the soil. Steam sterilization also is recommended for gravel mixtures used in hydroponic operations following the same procedure described above.

@intensive

You are right. If you are spraying your leaves with Epsom salts, you are just treating a magnesium deficiency.

The Virus can't be cured, once it is in the plants.

And no, you won't die if you smoke it.

control the vectors.

whiteflies, aphids and such spread a shitload of viruses from tomato yellow leaf curl (pain in the ass) to the various mosaic viruses (not terrible in anything other than their eponymous crop, such as tobacco cucumber tomato cassava etc...), and a fuckload of bacterial and fungal infections.

once the virus is in a plant, you can pretty much assume ALL your plants in that room or plot have it. Thats why keeping your mother plants in a separate clean room is so important.

it's ok to grow them out, but if a mother plant is infected, dont take any clones from her. bud her and grow a new mother from seed.

the only surefire way to protect your plants from these viruses fungi and bacteria is to keep the pests in check. if you garden outdoors, use this stuff once a week in a hand or pressure sprayer (wear protection!, it BURNS!! but wont otherwise hurt you, it's food):

in a saucepan on the stove, simmer

3 cups water
a large handful of peppermint leaves and stems
6 cloves fresh garlic finely minced (no powdered garlic! it doesnt work and clogs your sprayer!)
3 tablespoons (or more) cayenne pepper flakes

simmer for 45 minutes strain through a cloth (piece of old T-shirt works good) let cool and pour into sprayer add 1 tablespoon biodegradable dish soap, top off sprayer with water put on a dust mask and ski goggles (super important) and SPRAY EVERYWHERE!
wash hands thoroughly with soap before touching eyes mouth genitals or butthole (really really hot stuff)

it's non toxic (just spicy as hell) and washes off with water easily do not use on your buds unless you're a masochist. wash any produce before eating. and seriously, wash hands with soap before wiping your ass or holding your dick.

once a week will keep aphids slugs snails and whiteflies in check like a motherfucker.

Warning: may attract Hispanic, Thai, and Punjabi cuisine aficionados. do not store near salsa fixins or noodles and shrimp.

dont soak your soil with this stuff though, worms hate this spicy condiment on their dirt.

indoors, put a single layer of nylon ( pantyhose fabric) over your air intake vents, and seal cracks and crevices that might let a flea in. (expanding foam is your friend)

if you have a problem bug indoors, get that soil outdoors. and send it through your compost heap or worm farm. you could also dump it in your garden then sprinkle it with Sevin Dust before turning it in, or letting it lie fallow till next spring.

otherwise healthy plants with a bug problem can be repotted in fresh soil (unless they are fruiting or flowering) by washing the root ball in a warm water bath and gently massaging the bad dirt away. you can then replant in fresh clean dirt, and your plant will be back on track in a day or two.

allowing your soil to get a little dry before watering will prevent and eliminate fungus gnats (annoying but harmless to your plants) thrips (deadly sap suckers) and other soil breeding bugs.

gently shaking Sevin on your soil surface indoors will protect your plants well against anything that might be lurking in the soil if youre not afraid of pesticides.

Thank you for taking the time to post this. Hopefully this is an isolated case. A while back I got the spider mite infestation from hell and certainly do not want a pathogen or anything else ever again. I had to completely kill off everything, wash and start all over again. Cost me about 2-3 months of time to re-group. An ounce of prevention I say. I hope we don't get this up here in Northern CA! I certainly won't be careless again and your warning comes at the perfect time for me. Thank you again.

all the mosaic viruses are present in northern california too, except maybe the coffee and cassava mosaic viruses. this is why most tomato farms dont allow smoking or chewing tobacco in their feilds (too bad its the bugs that carry the diseases, not cigarettes)

thats why controlling the vectors (insect pests mostly) is so important.
