| Abstract: | Nitrogen fixation YKT is a kind of bacteria with the ability of bio-control to root knot nematodes. An exploring study on potted plant effect, larva virulence and eggs hatching has been carried out. The result showed it had prominent effect on root knot nematodes. The root-knot index reduced by 60%. Larva's revising mortality reached as high as 50%, and egg hatching was also inhibited significantly. |
