Dud Identification Collective Knowledge.

I don't think P.O is directly responsible for everything... I just remember APE taking trays and trays of cuts to them from everybody he knew and never treated them for shit or even verified them ... When the Tahoe got released... I swear it just started spreading more and more.. OG Kush genetics DUD out quick to these fuckers...

Nortica aka Bacillus Firmus doesn't have Ditylenchus dipsaci on its label... but ...

[FONT=Arial,Bold][FONT=Arial,Bold]same exact product sure does label them [/FONT][/FONT]

[FONT=Arial,Bold][FONT=Arial,Bold]

NEMOEND-BF is also effective against other phytopathogenic nematodes such as​

[FONT=Arial,Italic][FONT=Arial,Italic]
Ditylenchus dipsaci [/FONT][/FONT]etc.

This doesn't kill them.... it puts a barrier around the roots and protects them...while releasing indole-3-acetic acid giving the roots a nice growth burst .. nematodes starve out..

use this in combination with say Chitosan ...should be amazing ... all the benefits the plant gets besides the nematicidal effects.... SAR activation etc

Triacontanol has nothing to do with this problem... Ive been using the stuff way before these guys hit the scene... come on now

Just look at these forums on how much in detail Spurr and myself blew that topic of Triacontanol up...

More like People growing outdoors getting infected around the 2009 outbreak of the Stem Nematode... Progressive Option gets dirty cuts... and passes them out...Shit started in Cali.... right when the ASN had its major coming out party.... makes perfect sense...helps to live in Cali and have actually had this problem....

If these guys enter through the stomata... then this is awesome... I'll have these bastards killed in no time... I can already tell major improvements in my genetics from the last couple weeks of intense IPM...

Ive been fogging everything with the stuff....dip unrooted clones in it also...just kind of expensive....but its legit

Maybe you need to read the post again, and all the other posts leading up to it. I didn't say triacontanol caused it. I said these things live and breed in alfalfa. Many people use alfalfa as a natural source of triacontanol. Therefore it makes sense that alfalfa being used in people's mixes is probably the initial cause of the spread of Ditylenchus dipsaci, which breed in only two plants: alfalfa & sainfoin. They do not reproduce in cannabis. Which part of that don't you understand? You do realize that people use alfalfa in their mix, right? If not, Google it. It's quite common.
Here's a repost of the part that you apparently missed:
"Alfalfa Stem Nmatodes can parasitize and persist on a number of host plant species, but can only reproduce in alfalfa and sainfoin." Here's the link:
http://utahpests.usu.edu/IPM/htm/field-crops/insects-and-diseases/alfalfa-stem-nematode

That being the case, it makes perfect sense that the alfalfa being used by many is the cause of the spread of these. They cannot reproduce in cannabis.

Except that Ditylenchus dipsaci don't live in the roots, they live in the plant cells, and they don't enter through the roots , they enter through the stomata. They are not like other nematodes that live in the soil. If they were,predator nematodes would take care of them. That is why they are so difficult to deal with.

G`day Retro

The reproduce only in alfalfa was what got me thinkin .
I`m not ready to do a Stormy and say that`s 10 000 % it . But it is worth consideration . Alfalfa = stem nematode . Triacontinol and some teas use it . I`m not sure how its processed . So I don`t know if they would be killed in the process . But that`s where I`d do some investigation . Alfalfa products . Seems to make sense ?

Thanks for sharin

EB .

People use alfalfa directly in their mix to make use of the triacontanol that occurs naturally in it. No processing involved. Straight alfalfa, where they live and reproduce. Google "alfalfa, cannabis", and you will see what I am talking about. No way would I use alfalfa after reading/studying about this stuff. I would only use triacontanol that comes in a bottle.

I've also ran po's tahoe without dudd issues, the hells og was a different story...I did a run of their tahoe,larry, 91og, louis, hells, and the earthshaker; Earthshaker and hells were all dudds. This was in 2011-2012. The tahoe was actually some super fire...wish I kept cuts of that one, just figured it would be easy enough to get it back(jokes on me lol). I really liked the Larry too, chunkier, slightly more on the lemon side of the og spectrum...I should try to get some undudded of both but I don't wan't to make a whole order that probably won't get filled and the thought making that drive and potentially getting hung up in that 3-7pm la traffic with no idea of whether or not they will have the specific cuts in stock for walk ins makes it not practical, unless I'm already in the area for one reason or another.

Except that it's an Algaecide, Bactericide & Fungicide.
NOT a nematicide.

G`day Stormy

Your back on the C130 Gunship approach .
If you do defeat these pests . How will you know what was responsible ?

Why use 10 different chemicals at once or in succession . If the 1st one takes time to do its job ?
It may be working , but before its finished you add another chem .
If the problem goes away . Then what do you credit with for the action ?
It would be impossible to know .

Which would mean if it happens again,you break out the same cocktail .Not knowing what the key ingredient is .
Ideally you`d use 1 cut for 1 treatment and observe it . Another treatment on another cut . And as in a lab, 1 untreated as a control .Treated with nothing to see the differences . Your regime ATM is using a lot of time and money chasing moon beams .

Your regime may be effective but what was responsible ? And did it work alone ?
Knowing those answers .Could save you a lot of time and money .

The original Tahoe was a 10 from PO.... I love that cut

Xerotron even in small dosages can melt your skin....using it to fog and disinfectant everything

sorry to drag this thread off topic
............but YES! you still rockin her? Wish I held onto it, was a truly special og

po's Tahoe og-non dudd

you can see one of the dudded hells or earthshakers in the background of pic 1 & 2

 

[Storm Shadow]

I never let that cut get far away from me.... its the best herb I've grown

Flavor and potency off the charts

 

[whadeezlrg]

100% agree

leave cuts in dumpsters much? lol

it's definitely a different cut than the dago crew tahoe fwiw

back to the regularly scheduled dudd show

 

[mofeta]

I missed where someone keyed these worms out. Whoever did it, good job! It is not easy, even for specialist, to resolve even just to species, but to determine not only that it was dipsaci, but that it specifically was the alfalfa race, wow, I'm impressed.

Did someone here do this, or was it a path lab that someone used? Sorry I haven't been paying close enough attention, I guess.

 

[Storm Shadow]

I found them.... and all the symptoms matched up to everything I was going through...

The Gene Encoding Protein these worms inject back into the plant... amazing... then the "White Flagging".... Everything matched up

I was so off about phytoplasma...but still all the reading/research led to the discovery of these monsters

 

[mofeta]

Hi Storm Shadow

Yeah I saw how you found the nematodes in your duds. What I meant is that I didn't see where anyone had positively identified them as being a particular race of a particular species of the multitude of known nematodes.

I just noticed that people were referring to these as alfalfa stem nematodes. I just figured that someone must have ruled out the other races of D. dipsaci (there are at least 10, no?). As it is not easy to make this determination, I was curious as to who did it.

And about the phytoplasma, hey that is much more interesting than nematodes, even these more-interesting-than-normal nematodes. I bet that some folks do have phtyoplasma in their weed, and if not, well, it is inevitable really.

This link shows how to test various ways, for different parts of plant infected. It is beyond me, not knowing about required equipment, or if there is way to do it cheap. If someone could explain, especially section 3, which test leaves and stems.

[Sam_Skunkman]

I'll bet they do reproduce in Cannabis, if you can find eggs and juveniles then they do for sure. D. dipsaci has at more then 20 races, I thought more, read my post in this thread #1300.
As far as I know these found in Cannabis have not been ID by professionals as yet. They should be. They could be more then one race, why not?
-SamS

 

[whatthe215]

Retrogrow - I think the nematodes certainly do reproduce inside of cannabis. I'm sure many of us (including myself) don't use any alfalfa products but still have them and see them spread.

If they only reproduce in alfalfa, how would they continue to thrive and spread for so long after getting them if no alfalfa products are being used?

Also I do believe that they can and do enter new plants through roots. I think Sam S said so a few pages back. Or maybe they get into soil and go straight for a wound in the stem.

 

[Loc Dog]

What post number conclusively identified this as Alfalfa, and not stem nematode???
