There aren't many published studies with B. firmus in relation to D Dipsaci, The few that pop up are studies performed in an in vitro setting.
The above quotes you copy and pasted on post #434 were taken from the same book whatthe215 just provided a link to. Interrelationships Between Microbial Antagonists Having Divergent Modes-of-action...
By Alexander Rafael Mendoza Luna

The link @SpiderKid provided Biocontrol Science and Technology The study was also done an in vitro setting, it also says " In general, juveniles of D. dipsaci were less affected by B. firmus culture filtrates than the other tested nematodes (Table 3)."
You gotta remember the primary disadvantages of in vitro studies is it can be challenging to extend the application/result from an in vitro setting back to the intact plant/biology.. Most people that will use these products aren't doing tissue cultures. So there must be a reason why products like Poncho-Votivo & Nortica WP did not include D. dipsaci in their list of target pests.

While studies show it was helpful to a degree but Its a little far fetched to say B Firmus will get rid of D. dispcaci, from the tad bit of info you provided. The studies showed it was far more effective for R. similis (Burrowing Nematode) & M, Incognita (Root-knot-nematodes) in vitro. This could be a costly investment if someone was to buy Nortica WP based on your post and later find out it doesn't work, so its best to be 100% sure it does work by providing more supporting field evidence or personal experience...

It looks like AVID plus B. Firmus, rotated on fresh cut clones should fix the problem. I checked a couple plants for about an hour, I have not seen any nematodes yet.

Yet I still have concerns about nematodes being the the sole reason behind dud'ing... This would imply that a dud'd plant being grown in medium that will be recycled would harbor nematodes and later infect any other plant later transplanted in the medium, and this is what has me very confused because my current run is healthy with no signs of dud'ing... But I hear more people are seeing signs of nematodes in there duds

@whatthe215 I have those trunks ready, let's see what we got..

I have the same problem with what I believe is fusarium, it does not look like there is anything to kill this out right so I'm thinking about trying to manage this with RootShield Plus. I should be able to use RootShield to protect anything new to the farm from infection while the older stuff is grown out with the aid of RootShield Plus and eliminated mostly by smoking. The Tabaco and Tomato farmers apparently use a 15 minute wash with 10% TSP followed by a 5 minute wash in 10% bleach of new seed. I did try the 15 minute wash in TSP but didn't feel lucky enough to do the 10% bleach wash so I didn't push my luck, so far so good I had a good germ rate and now have 1.5'' seedlings. I got desperate at 1 point and planted about a dozen sickly clones I thought would die into #4 sunshine mix along with gypsum ( ground up chunk of damaged drywall from my garage wall ) and composted animal manure to my supprise over a period of time pushed off to the side in my green house and shaded out by all the big plants they turned around and became healthy plants but still seemed to be slow growing. Yes the first 2'' of stock when split length wise has some skid marks on some plants but most of the brown out rot at least on these clones is around soil level internally on the stock.

I have a question for y'all: When you chop your dudded plants, what does the substrate smell like? I have noticed that my healthy plants, ie non-duds, smell like myco or mushroms. The substrate from my duds smell like mold.

any thoughts?

ok, I flushed the flower girls with flora kleen. Some of the pots had a good deal flush out of them - a couple were over 1200 ppm. Most were around 600. As soon as they dry, they will be fed lightly and i'll pray to get some trichome development. thanks for that tip!
