Alright guys I've got something to look at... I noticed another plant (this is out of about 35, most plants appear healthy although a bit 'off') going sort of downhill... check the base, same squishy, ugly material. Sacrificed this plant, scraped off some of the outer layer, and scoped with my USB scope.

Sorry for the shaky video quality, I had to hold the stalk and USB scope at the same time to get these fuckers visible.

And no, I'm not talking about the young springtail roaming around... Look closely for the wormlike critters slithering around the top middle-ish and top right.

Again, sorry for the poor quality, I'm working to get a better angle and something a bit more still.

Also, they appear to be only near the base. When I measure scale with the measuring tool with the scope, the appear to be about 1mm in length.

I noticed some strange red blotches on some of the roots near the base also, I'll try to get a pic of that.

Here is another video. Seems they die rather quickly when exposed to atmosphere. It was moving around a bit when I first located it, and once I started recording the movement slowed, then stopped.

If you notice in the first video, you can see one quite clearly that also is yellowish on one end and whiteish on the other. Again, using the measuring 'points' with the scope, I'd estimate about 1mm if straightened.

Certainly looks like a different creature than what whatthe215 posted...

Sounds like pythium do the roots skin slip off off if held firmly and slide up and down? Stems also a bit. But the roots will be yellowed and really screwed up.

Not necessarily Sam, no roots' skin slipping off...

But the stem, the outer layer comes off quite easily.

Root system clearly weakened though.

Weird shit.

Props to all involved trying to sort this mess out. I'm tuned in and following along, hoping I never get these fuckers in my garden!

 

[acridlab]

Is it possible the worms in question are potworms "enchytraeids",, eating up the decayed root tissue and stem caused by pythium or something?

 

[Elmer Bud]

G`day Acrid

The chicken or the egg ?
I have been considering that myself . Do the Todes come before or after the Pythium ?

Getting some identified will be a big step . Then we might find out if the Tode has a way of affecting the plant hormones . Or If its a combination .

I expect you will find traces of Pythium in a lot of samples . Though its not causing problems when the environment is under control . The summer heat would be the factor in a lot of these cases I expect .Interested to see if it slows down over winter ?

Thanks for sharin

I googled enchytraeids and did see some examples that resembled my specimen, particularly in my second video...

Hmm.

Anyone else starting to get freaked out by all these bugs? I sometimes feel like my skin is crawling. It's just one plague after another. Where does it end? First it was root aphids causing a lot of devastation. As soon as we figured out how to kill them, it was broad and cyclamen mites. We figured out how to deal with them,although they are still causing massive problems for many people. Now we got nematodes, which seem to be kicking our ass so far. And now more types of worms, enchytraeids, which don't seem destructive, but psyllids certainly are, and there is no magic bullet to kill them. There are things that knock them back or control them if you catch them early, but if you don't catch them early, they can wipe you out. We never had to deal with any of this stuff in the "old days". Now it's plagues of biblical proportions, one after another. I still wonder how much of this stuff is being spread intentionally, and no, I'm not generally a conspiracy theorist.
I was reading last night about killing these pathogens with CO2, helium, or nitrogen gas, although nematodes don't even have a respiratory system, so don't know if gas would have any effect on them. As far as these other pathogens, I was reading how peeps use large hefty trash bags and put the affected plants in them, and then inject gas into the bags and tie them off, and just let them sit in the concentrated gas which supposedly kills anything. I suppose you could do the same thing with a small room/closet, and put large amounts of nitrogen, helium or CO2 into them, and keep them sealed for 24 hours. Wondering if anyone here has tried this method or knows anything abut it?

Annnnd the plot thickens lol.

grey skull blamed it on the government years ago, :biggrin

we all know its from passing cuts, there is no denying it, we just have to deal with it, makes spider mites seem like a walk in the park, I have to believe with all of us working togather we will beat it, whats next is the scary part.

Be very careful with CO2. Get a PPM meter and alarms. Check at floor level. People and pets have died from CO2.

Have you had any luck with heat treatments?

You sure you're not thinking of carbon monoxide. I know co2 can be toxic but I've not heard of growers or their pets dying.

 

[xxxstr8edgexxx]

i found a half a cup of depleted uranium in the rez totally wipes the nematodes out. anyone else tried this?

Was reading about it as warning to growers, but can not recall where.

Here is a general link -

http://www.ehow.com/info_8696252_stages-death-carbon-dioxide.html

It settles to floor, which is why I expect pet fatalities would come first.

Tried hydro in late 1980's with CO2, and had test kit to check level. Was shooting for 1000 PPM, and knew then, that it was possible to kill.

That's correct. CO2 can kill you. It binds with hemoglobin in the blood. If it displaces the oxygen in the room, you will die, and it's 150% heavier than oxygen, so settles at the bottom of the room/space.

"There's another factor. The body produces CO2 and it has a system for monitoring how much CO2 there is in the blood. If that level is high, it increases the breathing rate to get rid of the excess.
In an atmosphere of pure CO2 that would tend to drive residual oxygen out of the body faster than an atmosphere of, for example, nitrogen.
However there's another mechanism that's more likely to make a difference.
If the brain is deprived of oxygen you faint.
Normally, that's a good thing since it makes you lie down and that stops gravity draining blood + oxygen away from the brain.
However, if you are in a room with no oxygen and you faint then you are not in a position to save yourself.

The practical outcome of all this is that you should never enter a confined space unless you have tested the atmosphere and know for certain that there is enough oxygen."

In the UK, it's considered important enough to have its own law:

No, but I think you should do a test for the board. In the interests of science, of course. You will have to put warning labels on the final product, though, as it will be your final product.

I wanted to make sure RG, and anyone that read, knew that when concentrated, could be fatal, and its propensity to settle on floor.

Yes. Dispensaries passing cuts. PO a prime example. But who's to say the DEA does not own or have their tentacles into dispensaries? If you've ever dealt with the DEA, you know they are beneath contempt. Just sayin.....
