Under greenhouse conditions, resistant and susceptible tomato cultivars were inoculated with avirulent and virulent root-knot nematode and root-rot fungus individually, sequentially or simultaneously. Early infection by M. javanica predisposed host plant to root rot fungus infection on both cultivars and concomitant infection enhanced fungal disease on susceptible one. Otherwise, the occurrence of interaction of M. javanica and Fusarium oxysporum f.sp. radicis-lycopersici didn't overcome the resistance of tomato towards nematode. Maximum disease complex registered with concomitant inoculation indicating that the synergetic interaction between avirulent and virulent isolates of M. javanica and root rot fungi occurred on susceptible and resistant tomato crop.
