The root-knot and cyst nematodes were distributed throughout the southern area, and they have given farmers a great loss.
The physiological specialization of several kinds of root-knot nematodes was apparent, but it was difficult to find the phenomenon of specialization according to the different districts.
The damage levels became heavier with occurrence levels of root-knot nematodes, but the relationshop was not consistent with relatively low or high levels of inoculation.
Injury by comtinuous cropping was high at 3-4 years of continuous croppong, low at 1-2 years and slowly appeared over 5 years.
