how did you Or (she) figure it out?
how did you confirm this?
I just sliced open the stem of the DUD Witches Broom Plants I have.....
Zoomed in 200X ... Saw lil Micro Worms smaller than any mite Ive ever seen doing laps and flipping me off in the process

Lets all put together a program that will NUKE these fucken bastards so far back in time that they will cease to ever exist again!!!!!! Lets Kill them and make them suffer ... Lets destroy them and teach em lesson to stay far away from our lives!!!
thats been quite the devastating lil critter for ya storm. holy shit.
well im glad you figured it out, i hope youre correct. and yes kill kill kill.
nematicides are fumigants from what im reading however, treating the area and fallow the room clean up and unfortunately either get rid of plants or clone them in vitro. im not certain but i think if kept in vitro long enough they wouldnt survive. im reading up on it now.
G`day Stormie
Do you let your Mrs pick you up sneakers from car boot sales too ?
You have identified one pest .Congrats .
I learnt some thing as well . Though you could very well have more than one ailment . As per what Sam has said all along .
You explained you were 50 K in the hole .Don`t be cheap .
TAKE IT TO A LAB !!!
Interesting what your saying .
I suspected the roots and the phloem even the hormonal system .
Seeing small yellow leaves makes me consider the cytokinins and calcium and nitrogen . Leaf cells can`t divide quick enough to increase in size . And Auxin because of the no apical dominance .
But I thought it was a chemical / toxic blocking the functions . Not some thing physically damaging the vascular system .
Have you had a look below the level of the medium . ie Are they in the roots as well as the stem ??
I`d take the Chinese Medicine approach .
Look for the causation . Not the symptoms . How did this creature get in 1stly, to prevent it happening again . And what doesn`t it like so if it does get in again it doesn`t take up residence .
Thanks for sharin

that makes sense because one time i saw the government spraying microscopic nematodes out of an airplane onto a field of medical marijuana in northern california. you should have seen it. we were totally covered in microscopic nematodes.
Avid has shown good results and so has Pylon as soil drenches against them.... Also There are a few studies showing Kontos working as well.....
I have all these products and will test them out.... lets see if we can make a DUD turn back into a stud

some light reading on nematodes and a few nematicides listed in Table 1
http://www.fao.org/docrep/v9978e/v9978e08.htm
stre8edge, most nematicides are fumigants... then there are nematicides that can be watered in but they don't kill, just stun and paralyze apparently.
there was a new nematicide announced a few months back, called Nimitz, that can be watered in and completely kills nematodes. IDK if it's even been approved or released yet though.

Storm, take it to the lab for confirmation. Let's be 100% sure.

I went nuclear holocaust on my infected spot and I don't have any duds as far as I can tell... but I'll pickup my buddies awesome microscope and do some searching sometime this week.
Nimitz = fluensulfone

Just spoke to AL & L on the phone. Send samples to them via Fed Ex or UPS. No need to drive there. I asked her about BM toxins, but she knew nothing about them. I asked her about nematodes, and she said yes, they see them all the time. Plant parasitic nematodes, which normally infect only the roots,but can move to stems/leaves in some cases. Most nematodes are beneficial, and many here add them to their soil, however, 10-15% are parasitic, not only to plants, but also to animals, including humans. If stem, root & soil material are sent in, they can identify them.
These are the best links I could find on parasitic nematodes:

Methods of control:
For the past 50 years nematodes have been effectively controlled using chemical nematicides. These are inexpensive chemicals that effectively kill nematodes in soil. There are two types of nematicides, soil fumigants (gas) and non-fumigants (liquid or solid). Soil fumigants became popular because they did not rely on alternative host crops for rotation; they drastically reduced nematode populations in the soil, and were cost effective for most crops. Most fumigant nematicides have been banned by the EPA as environmental toxins with the exception of 1,3 dichloropropene (Telone II), chloropicrin (tear gas), and dazomet (Basamid). The multipurpose soil fumigant methyl bromide also provides excellent reduction of soil nematode populations, but methyl bromide was largely discontinued in 2005. Non-fumigant nematicides such as fenamiphos (Nemacur) and aldicarb (Temik) are based upon the same kinds of active ingredients as many insecticides (i.e. nerve poisons) and can be applied in liquid or granular formulations. While non-fumigant nematicides reduce nematode populations, their effectiveness is not as consistent as that of fumigant nematicides. The EPA is also restricting the use of non-fumigant nematicides. Since nematicides are expensive to develop, new ones are rarely released on the market today. While nematicides are effective in controlling nematodes, they are only practical for use on high-value crops.

Since these are soil borne, probably why coco growers are not getting them. Should not be an issue in hydro.
Just another reason why I will never grow in soil indoors.....
We are talking about within the state of California. It's legal. In addition, you are only sending root, stem, and soil samples, no buds or leaves are necessary. I would vacuum seal them.
U can also use beneficial nematodes to kill the bad nematodes this might be the approach I would take first then go nucluer if that doesn't clear the issues.
Unless you commit a federal crime that the Feds are willing to prosecute then the fact that it's illegal is inconsequential. Fwiw. FedEx generally disposes of shit like this in the rare occurance that they would find this much less even know what they were looking at. If they called the Feds they would not pursue small amounts of marijuana. Especially when there is no way to identify the person responsible for sending it.
I think it's a relatively risk free move. Especially if you have the good sense to use anonymity.
