Interaction between artificial inoculation of Meloidogyne javanica and fusarium oxysporum on green and red bean cultivars; Contender and Naz respectively, under greenhouse conditions was studied. A randomized block design with six treatments and four replications was used. Level of inoculum was 5000 j2 of nematode and 1.0 g of mycelia mat of fungus per 800 g of soil. Synergistic interaction occurred between the two pathogens on bean cultivars both in concomitant and sequential (first nematode, then fungus, after two weeks) inoculations. The growth parameters (lengh of fresh root and shoot, dry weights of root and shoot) reduction was more pronounced with inoculation of either of the pathogens alone. The number of knot formation on root and density of nematode reproduction were very low when inoculation was initially conducted with the fungus then with nematode. The minimum rate of wilting next to control was observed when the plants were inoculated with nematode alone. Maximum wilting symptoms were observed when both nematode and fungus were inoculated concomitantly
