MeloCon WG Biological Nematicide

MeloCon WG is a biological nematicide that contains a naturally occurring fungus, Paecilomyces lilacinus, that is a highly effective parasite of all stages of development of common plant-infecting nematodes, especially the eggs and infectious juveniles.

note is a health issue to humans with use of this make sure to read this pdf if use of melocon wg is used !!!!

That stuff sounds really dangerous. Can cause heart infection in humans, damn.

I'd also like to know what scope/camera this is.... :)

$400


for $430 you can have a binocular so you can view with eyes and camera.


the camera on both of those is not too great. it lags a little and flares when adjusting brightness. runs only 2-3 frames per second at HD resolution. i think that's why they're so cheap, getting the old model cameras out. but it works and is relatively cheap.

More info on natural predators, chitin, trap crops and essential oils.

Tardigrades, Turbellaria, Mites, Amoebae, Collembolla
Cool video on the Tardigrade. Shows how the guy collects them.

Natural Enemies & Biological Controls
  • Predators and Parasites of Pest Nematodes
    • Predators and parasites of nematodes can be used to prevent and compete, but they have not been shown to consistently reduce nematode damage.
    • Predators and Parasites of Pest Nematodes include:
      • fungi
      • bacteria
      • beneficial nematodes
      • soil-dwelling insects like collembola
    • Ways to add Predators & Competitors:
      • Compost
      • Compost tea
      • composted manure, especially chicken manure
      • Commercially available beneficial nematode applications?
  • Marigolds
    • I was unable to find any resources that discuss marigolds in conjuction with Stem & Bulb Nematodes; only pest nematodes, in general, or root-knot nematodes, specifically.
    • Only French marigolds (Tagetes patula) and African marigolds (T. erecta) have nematicidal properties, but they only work if done in a continuous cover crop, with weeds kept out. Work them into the soil after 2 months of growth. This can be done with a lawn mower or weed whacker.Let them dry for a few days then turn them under
    • What happens with the marigolds and the nematodes is that the marigold attracts the nematodes, but when they attack the roots, the root releases ozone, which kills the nematode.
Trap Crops
Sprays or Dusts
  • Chitin
    • Chitin is a protein found in the walls of the nematodes. Many fungi that attack nematodes do so by breaking down the chitin, exposing the nematode to infection or dessication. Adding extra chitin to the soil stimulates the fungi population and seems to speed their action against the nematodes. There are products available with chitin in them, but they may not be considered organic due to their urea content, which is a synthetic fertilizer.
    • Here are some options:
      • crushed crustacean shells (shrimp, crab, etc.)
      • EcoPoly 21 (TM) Microshrimp fertilizer is a shrimp-shell-based fertilizer
  • Ground Sesame Stalks
    • certified organic growers can try a product made from ground sesame stalks, which suppresses many species of harmful nematodes.
  • Essential Oils
    • Anecdotal evidence shows that essential oils like mint or oregano can be used to control nematodes.

@nightmarecreature where did you get the info that says that product will get rid of the stem nematodes? Please post that info.... Same with thaPoncho-Votivo that @leadsled posted.. Both these products don't list stem nematodes. The active ingredient seems to protect the roots and stem nematodes are mainly found in the stems..

Nortica is not labeled for stem nematodes (d. dipsaci) so if what we are dealing with is in fact d. dipsaci than no, Nortica will not get rid of them.

Bacillus Firmus takes care of five or six different types of nematodes, including Dipsaci.

Where is your source of this information?
Click to expand...
I've found several sources but here is one. The Agriculture industry is way ahead of us. Nematode treatment is too expensive on a large scale for crops. Like I said before, B. Firmus treats five or six different types. More of us could be infected than we think, I have not found any nematodes but I'm going to continue to look.


"B. Firmus isolated from the products and fermented under controlled conditions cause paralysis and or/or mortality of mobile stages of R. similis, M. incognita and D. dipsaci."

"B. Firmus produced in Triptic Soy Broth media contained bioactive compounds that caused significant levels of paralysis and mortality to R similis, M. incognita and D. dipsaci."

Pesticides that contain Methyl Iodide are very effective but highly toxic.

"To conclude, there seem to exist two or more valid species in the D. dipsaci complex, but they have not yet been validly or completely described and differentiated."

"D. dipsaci has been shown to be seedborne on about 15 plant species"

"D. Dipsaci is known to infect over 450 plant species"

I do see 1 bacillus firmus product that has dipsaci on the label, neomoend-BF, but it's some random indian chem company.


The one study I found on in-vitro relations between bacillus firmus and d. dipsaci says that it wasn't very effective.
http://books.google.com/books?id=bW...g&ved=0CCcQ6AEwAQ#v=onepage&q=dipsaci&f=false

I don't doubt that it might help, but it's far from a cure.

I posted that there are several types of D. dipsaci. Most experiments with B. Firmus say that it's effective, that was the only one I read that says otherwise. There are several fumigants that cure nematode infections. People tend to panick and act like there is no cure, the agriculture industry is far ahead of us. Not only is there a cure for nematodes, there are several chemicals that kill them. Methyl Bromide, Methyl Iodide, B. Firmus, Paecilomyces lilacinusStrain 251,fluopyram, Formaldehyde.

Yes, even Abamectin (AVID) kill D. Dipsaci. 93% of Garlic Bulbs treated with Abamectin, were nematode free.
http://eurekamag.com/research/003/583/003583495.php

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.

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...
