"Sugar Drench:
Target insects: Bad nematodes! Sugar also adds trace minerals to the soil.
- Mix 1/2 a cup of sugar with 1 gallon of water. Stir to dissolve sugar. Pour on the soil around plant roots where you have had nematode problems or use as a treatment prior to planting."
Polar_lace thanks for the info. However I would not recycle the soil without 100% eradication of these pests. From one of your links it says....
"Soil solarization can control root-knot nematodes. Soil temperature that reaches 125 degrees F for 30 minutes can kill root-knot."(Note it says can, not does for sure)
So if this is correct boiling the soil for a few minutes should probably eliminate these guys.
Anyone else have any useful info about what temps and how long to fry rootknot nematodes. Thanks.
