Tobacco Mosaic Virus! Serious! With pics!

[chuck estevez]

This is a revised article of our early 2012 WT Post. Please note that these issues were mainly occurring during 2011 and the high percentages of infestations taking place have died down substantially. Some information here is sourced, some information is directly from P.O. and it’s breeders / members.

​

There has been a fluctuation of posts regarding “TMV/Virus/Disease” related issues hitting various cannabis cultivation forums in 2011. We thought we would share all of the information we, and our friend Oswizzle have managed to gather regarding those issues.Although this was a new problem to Southern California, this issue has been commonly occurring in Northern California and other parts. The issues initially started in late 2009 where a large amount of forum subscribers on” ICMAG” and other dominant forums began posting a new plant “virus” they couldn’t deal with. These so called “Virus” scares commonly turned out to be “Broad Mites”. As this was a new issue at the time, we’ve collected an extensive amount of information and thought we’d share it with our members and patients. These Broad Mites can be taken care of simply by being treated as one would treat Spider Mites or any pest infestation. Please, all growers take the time to read the information below extensively as it will save you time and increase your cultivation knowledge substantially.Broad Mite damage exhibits the following signs (Remember many issues exhibit these signs so please don’t assume Broad Mites without checking thoroughly with a microscope):- Yellowing Tops- Slow / Stunted Growth- Curling of the leaves (More often concentrated on new growth)- Pale stem hue- Blotches / Destroyed Pistils

...... Ok people seriously STOP giving misinformation you need to be 100% sure or at least confident that you know what you are talking about when posting because i can tell everyone in here right now that this is 100% some sort of mosaic infection. END OF STORY. I have dealt with virus infected plants numerous times and this is a very stand out example of TMV and the dead giveaway is the yellow discoloration radiating from the veins and the hooking of the leaves not to mention the giant splotches of dead tissue.... when you spread misinformation you spread the virus its that simple and because of misinformation like that provided in this thread now the virus is hitting all the way through california and even nailing growers in texas and mexico! Keep your grows clean and get a test kit at this website. https://orders.agdia.com/InventoryD.asp?attribute_Size=5&collection=ISK+57400&loc=IN

It's fucking AMAZING to me how many people are so IGNORANT and UNINFORMED when it comes to TMV. It DOES effect cannabis as well as tomatoes, peppers, and a whole fucking list of other plants. It's fucking real. Before you try and blame this on a PH problem or some other underthought misdiagnosis, set your pride aside for a second and ADMIT that you DO NOT know everything. Do your FUCKING research before you open your mouth.

 

[Mr. Anomaly]

tsk,tsk,tsk. Promoting products for a non existent problem.

Reported to the mods for being belligerent and constantly rude. If you ever want to be taken serious in the cannabis community i suggest you start prying yourself out from under your rock and read a couple books... But just to sum up what i was saying, TMV also known as HSV (when it infects cannabis) is VERY real the symptoms include variegation radiating from veins (more common in high humidity) and specks with light green or yellow "halos" surrounding them (common in dry conditions) other common viral indicators include hooked leaves with necrosis on the side that is curved and what looks to be insect damage or leaves growing missing portions (make sure to take any insects that may be present into account) also look for yellow blistering between veins but the only 100% way to know for sure is to pick up a test kit from a good horticulture supply website (there are many sites not just the Agdia site but they are who i trust in terms of quality and reliability)

I thought it could only effect plants in the "solanacea" family or whatever, MJ isn't a solanacea right?

Cannabis is part of its own little family, a very tight knit group called Cannabaceae which includes hops among others, there are different strains of mosaic virus that will infect MANY different plant families there are exactly nine (including cannabaceae) that can be infected with TMV or other forms of mosaic virus but the tests you can find will detect most of them, also you would have a better chance of getting a false positive with those tests due to plant tissue hormones rather than a false negative.

Hey peeps, i thought i'd add to the mix.. I'm across the pond and I've got a bit of a random looking lady...

Quick run down of the setup
Strain - Medical seeds - Channel+
Standard 400w, was vegged under MH then switched onto 12/12 2 weeks ago and now under HPS
Been feeding it Plant Magic Old Timer and PM additives like i always do and i have bin using the same nutes for over a year now with different strains and in my couple years of growing I have never seen anything like this...




Any thoughts? Should i cut her down

I'm gutted, from what i've been reading its this TMV but then again the whole Broad mites thing has got me thinking... Tomorrow i'l be finding a scope and checking it out properly at the moment shes in quarantine With such conflicting information from many sources I just don't know what to do but hoping the scope will help... She was in my tent with 1 other Channel+ and 2 EmDogs (all which look fine... touch wood)
I've ran the Critical + a few times and thought it was a good quick and reliable strain to do on the side but got recommended the Channel+ on how it was very similar but better I got a pack and this happens....but only one 1 out of 2 of them... Both are looking amazing and much better and faster growth compared to Critical+ it was making it look proper inferior... such a shame... I think i might

I'm gonna go roll up listen to some jazz and read my nuts off


Peace

 

[Mr. Anomaly]

The hooking with variegation on the same side is a very common viral indicator but to be 100% sure i recommend you test for it just for peace of mind (they only cost 40 dollars including shipping from most sites). Chem D's for some reason have a genetic mutation that gives them variegation sometimes very heavy but being that this is not a chem d in question the yellow that is radiating from the veins and sickle leaves are not such a good sign.

 

[Mr. Anomaly]

Also there is some significant blistering evident in the first photo you provided which leads me to further believe that you might indeed have an infected plant.

 

[hexthat]

TMV haha i still say cannabis can get it but ive never tested the plants i thought for ether TMV or broadmites so eh... also some fungi can give symptoms like that

 

[Mr. Anomaly]

That is a really poor practice IMHO if you suspect a plant to be infected with such a awful contagious crop reducing virus you should ALWAYS test.

eh id rather keep it around and breed resistant strains then run from it

It's broad mites. 95% percent for sure. These fuckers r sweeping the nation. Dude talking about mis information, bullshit. Them r broad mites cow girl.

Ok i can repeat everything again or you can go to the start of this thread see the symptoms that were posted and then shove your whole "Them r broad mites cow girl" bit where it belongs.
Broad mites don't cause variegation that radiates from the veins and it most certainly does not create sickle shaped leaves with heavy necrosis on the side that is curved inward.
I don't mean to sound rude i am just very tired of people not doing the correct research and then calling bullshit on me saying i am mistaken because you haven't taken the time to review the initial post.

So you are going to create the first ever GMO cannabis plant? oh ok.

 

[Mr. Anomaly]

Actually take that back maybe not the first but the amount of time it would take and not to mention the amount of money would be HIGHLY unrealistic.

Fucking broad mites friend. Don't get all Upset cuz u think u know all and u can't be challenged on a plant problem. Yea your the only one doing research. Fucking really??? Lov u tons.

 

[cooliomang]

Can someone let me know if my baby is infected? got 3 nirvana auto blue mystic and 2 are doing good but this one has this discoloration since the beginning of its growth

 

[cooliomang]

anyone? please some advice would be great

 

[Rusty Shakelford]

I swear everyone should have had at least one plant that has done this by now. I have had one or two in the past, with one being recent. She was a Landrace Afghan Kush, and had that same Mottling.. It didn't spread to other plants, and would also grow out of it in some cases (I cloned them), so it was not pests, and in the end didn't seem to effect anything. I bet your plant is still growing just fine other than the Leaf Discoloration right?
