In this research interaction between Root-Knot nematode Meloidogyne incognita (Race 2) and wilt fungi Verticillium dahliae was studied in a Completely Randomize Design with four replications and eight treatments in greenhouse experiment. For each fungi treatment 40 microsclerote per gram soil pot and each nematode treatment 10000 eggs and J2 in each pot were assigned. Results showed that Root-Knot nematode increase severity and rate wilting caused by V. dahliae. But treatments without fungi showed no symptoms of wilting. The growth factors rate of treatments which have received both fungi and nematodes, in comparison to control and treatments which one of these treatments (fungi or nematode) received lonely decreased. Measures analysis of variance indicated that simultaneously and alternatively inoculations effects of both organisms were significant (P01) for severity of verticillium wilt. Inoculation of the V. dahliae two weeks after the M. incognita resulted in a 61/45% wet weigh root loss, which was greater than the additive losses from treatments of the M. incognita and V. dahliae alone. Separate inoculations of the V dahliae and M. incognita reduced dry weight shoot by 13/91% and 22/5% respectively in compared with the control. When the V. dahliae was inoculated two week after M. incognita dry weigh root (64/40%) was significantly lesser than in any of the other treatments. The percentage of Verticillium wilt increased further to 83/4% when the V. dahliae was inoculated two week after M. incognita.
