Inoculation experiments confirmed that the potential root-worm infection of rice can cause reduced production, mainly to reduce the effective panicle and 1000-grain weight; turn green stage for the susceptible period, during this period inoculated 300 per plant and 470 potential root-knot nematodes, respectively, 8.8 % And 13.5%. Comprehensive prevention and control measures include tobacco - rice rotation, rice straw, winter over winter species, the use of disease-resistant varieties and agents control.
