Here is a list (with links) to some of the products I have access to:
There are others I've missed, but the above covers what I've used and have readily available at the local Hydro stores. I sure would love to find a source for the raw strains minus all the marketing and up-pricing. There's probably an ag supply station somewhere not too far away where I could get into that, but to date I haven't managed to locate one that has what I'm looking for. Others on this forum might post a comment with their favorite products, like RootShield, a Trich.-based formulation I haven't used before (http://www.bioworksinc.com/products/rootshield-wp.php). As to my worm-castings, I've tossed them all out (along with the bins and trays). They've become part of a more standard compost bin. I don't know that the worms have survived the relocation. I think they're gone. Plenty of fruit flies and stuff like that now though. I might start a new bin sometime down the road, but with more care. Thanks for all the help Ivan! -naysen |

Ivan, very interesting information! You should write a book
Naysen, I admire your persistence and attention to detail. Good luck with your experimentation - I look forward to reading about your future discoveries. Steve |

Hi Ivan,
Hope I'm not side tracking things too much, but I have a question on something you said to Naysen: ---------------------------------- and please, for the purpose of the experiment you shouldn't use your Worm- casting production, since it's still a very probable cause of the contamination. ---------------------------------- I was wondering, what would be the exact nature of this possible contamination. Could the castings actually be harboring the verticillium or fusarium, or are there come toxins the worms can produce or ????? (I'm esp. interested in this aspect of things as I have a worm bin too, although I have a strong suspicion that after the recent heat we've been having the whole thing might have to be dumped and restarted). Sorry if you've already explained this - I haven't been following all the details of everything as closely as I might have. Thanks! Anne |

It's amazing what 24 hours in the brewing machine can do for the microbial life in my AACT. Here a picture really doesn't do justice to the frantic bedlam that is all kinetic life in one drop under the microscope. It's kind of sad to watch the buggers draw down and fizzle up as the liquid slowly evaporates.
I guess this means it's working. |

Does the last picture has Paramecium caudatum?

Ella, you may be right. It had fuzzy cilia that wiggled as it moved. It's insides were in motion, like some kind of machinery. That was taken under immersion oil using the 100x objective. I'd have to check to see if I was using the eyepiece to make that 1000x or 2000x total magnification. I understand those things might communicate by use of photons, which is crazy. I think they just eat bacteria and dying plant tissue. I'm not sure how beneficial they are or aren't.

If you have a halogen light source swapping it out for LEDs stops the heat problem. Just my 2 cents worth. |

Hi beeman, that's not a bad idea, but I do have an LED light equipped microscope and the organisms seem to stay alive and mobile for more than enough time to take a good long look at them. I was just pointing out that it's a bit sad to see the stark difference between the hustle and bustle kinetic life from a newly dropped slide vs. a few hours later when I come back and it's dried under the platelet. It feels like a killing chamber, but I'm a benevolent killer in aggregate, considering how many of them I helped to multiply in my aerated bath culture.
Here's the last series from yesterday after 48+ hours of brewing. I should comment that pretty much every dot or spec or line in the static picture is in motion on the viewing screen. They certainly look more impressive in real-time. If most of the globs seem out of focus, it's owing both to the ho-hum quality of my microscope (not to mention my skill level with it) as well as the fact that there is a 3-dimentional effect in the medium even under a plate, and depth of field is limited. I've seen more and more diverse organisms in a drop of the AACT [tea] each time I pulled a sample. I performed a foliar application and soil drench with the 25-gal of product yesterday evening. I like to think my pepper plants responded well to the treatment last time -- they sure seemed to be much healthier with new green growth, and less dying yellow leaves. I wonder if they're more able to benefit from the soil drench since they're in SWC pots where the drench can hang around a bit rather than just wash through? -naysen Last edited by z_willus_d; July 17, 2013 at 12:33 PM. |

it's actually a very rare thing, but in his case seems like a very high probability: the only thing all of his infected plants had in common was worm- castings. yes, if worms had been fed with infected plant/fruit residues the pathogen will have a happy life in the bin, and will most likely stay there for long. but it only means one has to be cautios about their food and sanitation measures. in this case i would say that Naysen was most probably really really out of luck with it. br |

sorry, i didn't check the dictionary for the word 'sustainable' i used, took that it meant 'easy target to V.' anyway, you need to chose plants which are a totally easy target for V. but please, do not make seedling out of suckers there- chances that you'll get infected plants that way are huge, especially this late in the season. |

I just got off the phone with my UCD contact, and he had an update on additional tests that were performed on the second set of branch samples I provided. I had sent samples from both grafted and non-grafted vines from my garden. These were between 5-10" above the soil level but the sections I provided were those closest to the main trunk of the vine. Apparently, Fusarium can travel fast up the plant tissue while Verticillium is slower and less likely to infect that far up the plant. In short, I probably screwed up not sending in deep crown sections of the main stem.
In any event, he plated portions of my sample from the grafted and non-grafted bags on verticillium and fusarium media. The Fusarium finally grew out from a non-grafted sample. That was used to inoculate soil in a green house that was planted with plants susceptible to the different races of F and V. One type of plant, Early Tak 7, came down with the symptoms of F. They were able to tell from the look of it (cutting) that it was Race1. I'm not sure how you can tell this, but it must be obvious to those skilled in the art. So, we still don't have a smoking gun pointing to V., but the evidence doesn't add up so well that F Race 1 is really what harassed the garden for a 2nd year in a row. Now with all the Maxifort in play, Race1 Fusarium shouldn't be an issue. The test results seem to bear this out, in that they didn't see anything on the plates from grafted samples. Next steps: - Try Ivan's experiment. BTW, on this topic, the person I'm working with noted that none of the beneficial bacteria trials they're performing are really a solution for F. or V. This is the exact research that they're performing both in GH and field. There may be some beneficial effect, but nothing much it seems. I asked him for details on the procedure, and it is similar to what Ivan proscribed with the root covering and hole lining at plant-out. They also tested Trichoderma strains with no significant gains. So this doesn't seem to bode well for the AACT folks, or for me if I have race 2+ V, but it seems there are no hard answers to be had. I will note that this is second hand reporting (on my part) on incomplete research that's not yet published, so certainly take what I say on this topic with a grain. I will pull some grafted and non-grafted tomato plants soon as well as an eggplant that's particularly sad, and I will deliver these to the UCD plant pathology folks so they can do the proper plating. In a strange way, I'm really hoping we can finally get a clear sign as to V. and what race. Well that's the update. -naysen |

Yesterday, I had a personal visit from my UCD plant pathology benefactor. He walked the rows with me, and we played grim reapers to tomatodom in my garden beds. The non-grafted varieties all showed heavy signs of Fusarium, similar to what I documented here last week:
http://www.tomatoville.com/showpost....7&postcount=63 The grafted plants were less obviously Fusarium, but we both agreed that V was apparent in the rootstock crown not to mention foliage signs. He went away with several bags of samples, and I expect to have better results from the tests performed on this new, fresh batch of detritus. This weekend or next, I'll be transplanting a set of late fall plants to test Ivan's procedures. I doubt I'll get much if any fruit before winter sets in, but it's worth it to me to give the experiment a chance to yield results. |

I thought the root stock was supposed to be resistant to F&V? Don't tell me it's all hype again? |

Maxifort is resistant to two of the three main races of Fusarium, but it has no resistance to Vert so far as I know. I'll be looking for the optimum RS to fight Fusarium race-1 and V. race TBD for next year's garden.
