PlantFiles is getting a new look! Just in time for spring, we're rolling out a new look for the best online plants database. It will also work with your smart phones and mobile devices, so now you can take it with you on garden center visits or botanical garden tours. Questions or comments? Please post them here.
I pulled my squash & found the roots looking all knotted up. They look identical to the pics online of root knot nematodes. The info I've found says I can move the garden or try to find crops they don't like or r resistant. Is there no way to get rid of these things?
I've had sick plants with roots like that before, and wondered if they were nematodes. Sorry no one seems to be able to help.
I once read that a heavy dose of dry mustard powder, in the hole when planting pepper plants, would prevent their nematodes.
I just googled up a sheet from UC IPM. Nematodes sound like a really tough problem, suggestions are fallowing, rotating crops, and generally making other conditions better so plants and soil are healthy as possible going into the season.
If it is your first time to have root knot nematodes and you purchased those plants that have them, you might try drenching the soil / area you pulled them from with boiling water.
We got them from some tomato plants we purchased (when we lived in Alabama.) I didn't know what they were at the time so didn't know what to do but I wish that I had spent a few days pouring boiling water on the spots and anywhere the soil might have gotten contaminated with them.
We were never able to grow tomatoes, melons and many other common plants in that garden again. (We tried solarizing but it didn't work.)
Since we have moved to Texas we grow everything from seed. This keeps from introducing pests like root knot nematodes and spider mites to the current garden.
