Root knot nematodes

duajones · August 12, 2007

While watering my straight 8 cukes this afternoon, I noticed something at the surface of the soil. I pulled the one plant and it looks like I have rkn. This is a small area next to my deck where I grew Diva in the spring, and when I pulled the plants, there was no sign of them. Just what I needed. Should I be concerned about the rest of my garden, and what should I do?

Duane, reached any further conclusions? I was unsure as to whether or not it looked like root knot nematodes from what I could make out in the picture.

Was it in any way related to the pickle worm infestation you also posted about?

Suze, I am pretty sure they were rkn on my straight 8 plants. The pickle worm problem was on my Poona Kheera so not related

Looks like RKN--and cucumbers are a host plant. (google cucumber and RKN for images)

What can you do for next year? add lots of organic matter

See link for other ideas though some are not practical for the home gardener.

As far as the rest of your garden--when you pull the plants you can see the extent of the problem.

Good luck--they are such a pain.
