Fusarium wilt disease of tomato which is caused by Fusarium oxysporum f. sp. Lycopersici (Sacc) is considered one of the most important diseases on tomato, which causes damages ranges between 30-40%. This research was carried out to isolate the fungus which is responsible of fusarium wilt on tomato, also nematode (Meldogyne. Spp), and to determine the infection and severity of the diseases. Tomato hybrids had different responses to fusarium wilt, Domina hybrid was more susceptible, the infection percentage was (13%), followed by lina (9%) then Saly (2.3%), while Yosra hybrid was the most tolerant (0%). The results also showed that Yosra and Saly hybrids were the most tolerant to root knot nematodes (2.8%) and (6.9%) respectively. The result showed that response to infection by fusarium wilt and infection Meldogyne for Domina and Lina hybrids were (27.8%) and (19.1%) respectively. Also, grafting on N-Power rootstock increased the resistant to infection by fusarium wilt and root knot nematodes.
