In-vitro Evaluation of Different Fungicides and Bioagents against Fusarium oxysporum f. sp. Lycopersici

Fusarium wilt of tomato incited by Fusarium oxysporum f. sp. lycopersici is one of the biotic threats in profitable cultivation of tomato crop worldwide. Utilization of biocontrol agents along with fungicides is best suited for integrated disease management. The fungicides evaluated in vitro against Fusarium oxysporum f. sp. lycopersici were effective and reduced the mycelial growth significantly. Among that Carbendazim 50% WP, Copper oxychloride 50% WP and Carbendazim 25% + Mancozeb 50 % WS were found most effective with maximum growth inhibition (100%), (65.22%) and (100%) respectivly. Antagonist tested against Fusarium oxysporum f. sp. lycopersici in vitro significantly reduced the growth of test pathogen. Among that Trichoderma harzianum inhibited (52.33%) and Trichoderma virens (49.41%) found to be most effective with highest mycelial growth.
