What is needed is a list of local state labs that test for viral, bacterial, fungal pathogens as well as pests. I have heard that some state labs in some states like Colorado, will test for individuals, some states only test for legal producers like Washington that as I understand only will allow testing of legal licensed grows. Calif is somewhere inbetween and each agricultural lab in the same state can be different. Most do require state residency to accept samples to be tested.

If anyone has used any state Agricutural lab anywhere list here and we can start to get resources to identify the core problem or problems. Then we can get rid of the problem or problems. And prevent it in the future.

There are tests for viruses, bacteria, fungus, anyone use one? I can start a list of home kits, or sample at home and send off to be tested by a lab kits available.

If anyone can list any virus, bacteria, fungus that they think can be confused with damage from BM, CM, or RM, damage directly from the living mites or also damage from any toxins remaining from deceased mite populations.

We need good photos of each viruses effects on Cannabis, confirmed to be that virus. Same with any bacterial and fungal diseases that can get confused with BM, CM, RM damages.

I started a list of viruses that have been found in Cannabis, see post #23 in this thread, as well as some of the info about if there are tests, insect or other vectors, most do not seem to cause much lack of vigor, but the top 4 and a few more do. Wtiches broom does, see post #85 in this thread.

There is another place similar to this on the web. on there you will find a scary nocturnal creature. he has posted a picture worth mentioning. speculating fusarium he split a stem long ways down to the root of a very obvious dud after harvest. he then post pictures he found on the web of the same thing done to a fusarium infected plant. striking similarity. the pith or inner tissue of the stem is brown. i would be curious if anyone out there has a dud plant on hand they could this to and maybe a hea;thy plant they could do it to also to compare and post it if you find something similar. while this doesnt necessarily mean its proof positive of fusarium per se it does lend itself to being a strong possibility of that or another similar pathogen affecting the roots and or pith. very interesting. all the more reason toseek out a lab test on duds for the presence of fusarium or verticillium. anyone got a fresh dud or an old stem handy for pics?

I've encountered the potential fungal cause:

Fusarium or Verticillium. I've seen hemp canker as well later in the season when I could positively id sclerotium. The plant pictured is a green crack. I've only seen this on a handful of plants and they all came from Cali (green crack, blue dream, purple diesel). The local clones or plants I've started from seed haven't been infected.

The plant pictured produced maybe 75% the yield of its sisters. The quality wasn't that noticeably different however. It seems that a few of the clones I picked up in this lot had the infection and it was somewhat kept at bay through the growing season. This gives me hope that if people are experiencing duds that are caused by a fungal pathogen, then it might be possible to isolate from a healthy section of the plant.

to follow up what Sam suggested, that seems to be what inuyasha did.
Just say its a tomato plant - BRILLIANT

i had my testing done at my local agricultural extension office. not sure that this is necessarily an option for everyone since, technically, extension office labs aren't supposed to test cannabis (due to USDA federal funding guidelines), but i figured it was worth a try and submitted a plant labeled as tomato and it worked out fine. you will need to take in (or maybe you could overnight mail it) a plant sample consisting of the roots and the base of the crown (the very bottom of the stem/trunk) so you will have to kill a plant to get the sample. just ask them for a "plant diagnostic analysis" with a "fungal/bacterial culture" -- it costs about $20 and they will call you with the results after a couple days. if the extension office is not an option or there isn't one close by, any lab with plant/water/soil diagnostics should do, just look for one nearby (or make sure you can overnight to them) since they will need a fairly fresh sample.

Let's complicate matters beyond comprehension..!

In NorCal, SOME but sadly VERY FEW People have a keen and clear idea what is Tobacco Mosaic i.e. - and What are BM's, Cyclamens or Russets. It's quite simple - viruses are rare, BM's on traded clones or cuts from dispensaries etc., not at all.

The more time people deliberate the worse the problem gets..! It's a plague Guys..

I'm saying it's a fact that clubs in sol cali hand out fusarium and verticillium

never had it, got clones from down there, then had it, had it tested, came back fusarium

threw it all away, now it's gone, so ...........

You keep posting the same thing. We are all aware of the broad mite problem. However, there are other pathogens going around and many people are noticing it, and these same people are not idiots. They know the difference between BMs and fusarium. You are going to have to accept the FACT that the problems being experienced are NOT all caused by BMs.
Another indicator is: people are reporting that some "dud" plants are recovering when put outside in the sun. This would not happen with BMs, but a fungal infection might be helped by exposure to sunlight and lower humidity outside. It seems that fusarium is becoming epidemic, due to clubs/dispensaries selling infected cuts. I don't know why this is unreasonable to you. There is more than one plague. Simple as that.

It is pretty obvious not every problem with all duds can be found to be related to BM, CM, RM, or are you saying there are no viruses found in Cannabis? No bacterial diseases? No fungal diseases that are mixed up with duds from BM, CM, RM, damages?
It is not a plague for me, I have grown millions of plants and never had them once. I have found viruses, bacterial and fungal pathogens and many assorted pest insects and spider mites, during that time in my crops. I have seen BM, CM, RM, but not on my crops, I grow mostly from seed, but I have kept the same over 100 clones alive for 25 years, a few picked up viruses and I tossed them in the trash and replaced them with virus free back ups.
I have never gotten clones from a dispensary, not one, I only have my own clones in my library.
I guess I am trying to show you that although BM, CM, RM, were the worst problem you have faced with Cannabis so far, many have other problems that are more important to them. BM, CM, RM are not everyones worst problem, they are yours....
That said I am not trying to say that every problem and all problems do not need to be dealt with quickly and efficiently, they do.
Have you ever confirmed a virus in Cannabis, ever? You seem in denial.....
What about a bacterial pathogen? I know you have had fungal pathogens, everyone has.....
I have had viruses, bacterial, and fungal pathogens. No BM, CM, RM, for what it's worth.

"Did you find this post helpful?"

I wish the NO option was still available" perfect example of why it should be.


Why even ask if there is only one option?

Tried to manually circumvent not having "No" option, in case it's not blocked and the link was just not listed.

I think the first link you clicked accidentally gave that post a "Useful" rating. LOL.

For us Canna coco growers, trichoderma already in it. I also use Great White from the beginning to inoculate against these fungal pathogens. Also start seeds in Lightwarrior, which has Mycorrhizae fungi to colonize the root zone from birth. This increases the plants resistance to other fungal infections.
So far, have never had any issues with fusarium.

I think trichoderma is naturally occurring in coco, not just the Canna brand, if that's what you were referring to. I wondered about dry brick versions, though, whether the drying process permanently killed the trichoderma or whether rewetting will revive the spores?

This subject for some reason brings out the worst in Men.. Not sure why. Meanwhile, You Guys are dealing with something I conquered. So Hate on Me all You want. And Have Bugs.

C'mon People. Science is all that matters. Not personal Pride. Growing problems are not a reflection of One's self worth. Nor is being right.

There's a reason why certain people with Keen knowledge of the problem are NOT Taking part in this thread. It seems to court Mental Masturbation, and not progress.

It's a pissing contest now. With all Due respect, the venerable Controlling Sam S, has appointed Himself Mayor in a town he knows very little about. But, He'll find out everything for Us, the slobbering masses.. (reinvent the wheel).
