Antagonistic effects of Trichoderma spp. against Fusarium oxysporum f.sp. lycopersici causal agent of tomato wilt

In this study, the mycoparasitism inhibitory effects of five Trichoderma species (T. harzianum, T. koningi, T. longiconis, T. hamatum and T. viride) on the growth of the causal agent of tomato Fusarium wilt (Fusarium oxysporum f.sp. lycopersici) were investigated by dual culture in laboratory condition. In this step, the maximum and minimum inhibitory effect caused by T. harzianum and T. viride. In the greenhouse, the comparison of the efficacy of disease decrease was carried out between soil and seed treatments affected by T. harzianum spores. Results showed that seed treatment did not cause disease decrease but soil treatment caused disease decrease as 92%.
