An eggplant with on annuall production of about 49/4 tons is one of the popular and most consumable product many diseases cause or eliminate eggplant coops.

In the next step the effects of fungal antagonist isolated on fungus in the laboratory by using of cross cultuse method was investigaty antagonistic effects of two fungal isolates Trichoderma harzianum and Trichoderma viride nere investigated in greenhouse.In the greenhouse, the inaculum fluid was injected to a ratio of about 10% the upper third of the pots aer used and two thirds of the pots filled with sterile soil. The pots were kept unde greenhouse conditions for several days. Eraluation of biocontrol efficacy of antigonists in control of welting disease fusarium using soil tillage method simultaneously with eggplant plant culture. This test is based on a completely randomized design with the analysis of variance of abtained data and by using SPSS software.comparison of mean traits by Duncan test at 1% probabilily level. The results of greenhouse experiments showed that antagonist Trichoderma harzianum 39/38% of the disease was better controlled.
