Abstract：Fusarium oxysporum Cu20 was evaluated for its ability to colonize in cucumbers（Cucumis sativus L．）‘9330’and its pathogenicity on cucumbers．The results showed that Cu20 could not lead to disease symptom on cucumbers，despite the disease infection rate were 100%．And we studied the ability of Cu20 to control root-knot nematode（RKN）disease，caused by Meloidogyne incognita through a vaccination of nematodes on cucumbers，which are inoculated with Cu20．The results showed that having an inoculation of F. oxysporum Cu20 could decrease the infection rate of RKN，with the amount of root-knots cut down by 38.0%，which is significantly different with the CK.
