    Aim: The present research work was carried out to evaluate the efficacy of five Aspergillus species as biocontrol agent against the Fusarium oxysporum f. sp. lycopersici, the causal organism of tomato wilt disease, in in vitro condition. Materials and methods: Isolation and identification of F. oxysporum f. sp. lycopersici pathogen and In-vitro screening of antagonist native bio agents against F. oxysporum f. sp. lycopersici form tomato cultivated soil were collected from different areas in and around Mysore district which is located between latitude 11°45' to 12°40' N and longitude 75°57' to 77°15' E, Karnataka state, India. Five Aspergillus isolates were evaluated for their antagonistic activity against Fusarium oxysporum f. sp. lycopersici following the dual culture technique in vitro. Results: Biological control is an innovative, cost-effective and eco-friendly approach for control of diseases. In the present study, the bio-agents, isolated from indigenous soil, were identified based on morphological characteristics and spore structure. Five Aspergillus isolates, isolated from indigenous soil, displayed significant antagonistic activity and suppressed the growth of the pathogen. Among five, A. niger inhibited 80.33% growth of the pathogen, A. flavus isolate 1 and A. tamarii inhibited 77.03% growth of the pathogen when compared to control.
