Evaluation of biocontrol efficacy of <em>Trichoderma</em> spp. demonstrated effective potential of <em>Trichoderma</em> on reducing <em>Verticilium</em> disease on eggplant cultivars. Disease assessment was established by measuring disease incidence in root units (DI-RU) and in the above ground of eggplant cultivars (DI- AU). DI-RU% was recorded at 12.5%, 25.0%, 31.3% and 37.5% in T3, TC, T1 and T2 treatment respectively where DI-RU recorded in Tm2 controls; eggplants inoculated with <em>Verticillium</em> only was equal to 100.0%. Whereas, disease incidence outcomes in aerial part was DI- AU = 100.0 % in treatments TC and T2, 87.5% in T1 and 96.0% in T3 treatment where Tm2 controls were assessed with 100.0%.</p> Wafaa Mimoun Mokhtari Mohamed Achouri Abdellah Remah Hassan Boubaker ##submission.copyrightStatement## 2018-02-25 2018-02-25 417 421 10.5147/ajb.v0i0.172
