Unless you’re a newbie, you’re most likely aware of my years of struggling with root knot nematodes.  I would love to say that my newly discovered organic methods such as compost tea, wood chip mulch, and crab shell (chitin – pronounced kite-in) have eradicated my nemesis, but I can confidently announce that there’s progress!  Since starting my SFG in 2013, I’ve been solarizing every summer. 

Root Knot Nematodes - PROGRESS! 13641288_10208595618879511_6497234355320356435_o

Yesterday I discovered tomato plant roots all knotted up with nematodes. Sad  The good news is that by this time previous years I would have found RKN damage in all three of my SFG beds months ago!  The other good news is that I’ve discovered that I now have an army of microbes fighting with me. rock on  To borrow a title of a great book: "Teaming with Microbes", I’m not alone in my fight anymore.  In the coming months I’ll be watching to see how effective compost tea and crab shell chitin is in controlling RKN’s. 

Yesterday after pulling out as many of the infected roots I could find, I worked 4 Tbsp of crab meal to each infected square, and drenched it with my 48 hour brew of CT.  I may leave those squares empty for 4 weeks before replanting.  By the end of May if I still have a problem I’ll solarize the bed.  

One more thought, I've read from the beginning of my research that RKN's thrive in poor soil.  Well, I don't think I had a good grasp of what rich soil was.  The RKN's that I have aren't deterred by all the organic matter, which conflicts with all I've read.  And when I read that they don't do well in rich soil, I thought, "I've been fertilizing... I have NPK..."  Plus, I use plenty of organic matter...COMPOST... in my MM!  My hope is that as I keep enriching my MM with CT, worm castings, chitin, wood chip mulch, kelp meal (which I'm making myself now), etc. that I'll eventually eradicate those suckers with the help of my army of microbes.  Very Happy

Good to hear that you are making progress. I need to follow what you have done because I realized that is what I have too.

I found this interesting article from NC State...It suggest planting Rapeseed as a cover crop over the winter and turning it in in the spring

How do you make your own kelp meal. In CA, the seaweed is large, large stems, leaves and fans. I tried grinding it wet. Tried grinding it dried. Nothing worked.

Sanderson, are you using a blender or a food processor? I use the Ninja cup. Also, are you buying your kelp, or getting it from the beach? I buy my kelp from an Asian market. I rinse mine off  in case there is salt residue.  Here's the video that got me started with this.

Ralitaco, I'll may look into trying that. But I'm surprised to read that RKNs don't like brassicas, because whatever strain of RKN I have here likes most of the brassicas I grow too.

Thanks. We gathered the seaweed with which I experimented. I used a "tail-less" meat grinder. Very Happy Root Knot Nematodes - PROGRESS! Kelp_d10

Well, I think I found why the one tomato wasn't doing well.  Digging to prep a quick set of bush beans.  Pulled this out from the spot the celery was in before it got too hot.  Not sure if these are from the celery or the tomato.  Bad news I pulled some romaine that wasn't forming head due to heat and their roots showed the same bumps.

Looks all too familiar.  I've had root knot on various lettuce plants, so not surprised about the romaine.  It's never nice to find a RKN infection.

Fortunately, or maybe unfortunately, RKN is an endemic problem in OC getting plenty of coverage and attention.

I think I may be planting marigolds this winter.  http://www.ocregister.com/2015/06/10/plant-marigolds-to-stop-root-knot-nematodes/

I recommend French Marigolds. Some varieties of Marigolds will actually HOST some strains of RKNs, and I've seen it happen in my own garden. I was HORRIFIED!  Then came across an article about it that a professor at the University of Florida sent me which explains this. I wrote about this...

Can lettuce with RKN still be eaten?

Yes. Anything that has been infected with RKNs (unless it's a root crop like carrots) can be eaten.  The plant just cannot reach it's genetic potential, so the health of the plant will be impacted.

Post  OhioGardener 8/11/2018, 8:33 am

I stumbled on this old post while doing a search for another topic, and found it interesting. Several years ago I had a problem with RKN in my hoop-house garden (this was before raised beds or SFG), and when I talked with the local extension office about it, the guy recommended applying beneficial nematodes to destroy the destructive nematodes - he said it needed two releases, 3 weeks apart.  I ordered some ScanMask Beneficial Nematodes, stripped the garden of all plants, and sprayed on the beneficial nematodes.  Three weeks later I got the second batch and applied them.  That fall I planted the normal fall crops, and never saw another RKN damaged plant. The carrots were beautiful.

Has anyone else tried Beneficial Nematodes to control RKN?
