In vitro Management Fusarium Wilt of Tomato through Biological and Chemical Methods

Fusarium oxysporum f. sp. lycopersici cause tomato wilt is one of the major diseases on tomato which is soil and seed borne. Heavy inoculum in soil and favorable environment condition results in the death of infected plant and therefore total yield loss. Hence, an attempt was made in this study, with two antagonists, two fungicides (alone and combinations) against Fusarium tomato wilt. Pot culture studies found that Average reduction of F. oxysporum f. sp. lycopersici recorded with the test fungicides and bioagent ranged from 25.81% to 72.21%, as against 00.00% in untreated control. However, the fungicides and bioagents viz., Carbendazim 50% WP + T. harzianum resulted with (72.21%) maximum disease reduction, followed by Carbendazim 50% WP resulted with (62.96%) disease reduction, Carbendazim 25% + Mancozeb 50 % WS resulted with (61.10%) disease reduction, , T. harzianum resulted with (55.55%) disease reduction, Carbendazim 50% WP + T. virens resulted with (53.07%) disease reduction,, Carbendazim 25% + Mancozeb 50 % WS + T. harzianum resulted with (35.18%) disease reduction , T. virens resulted with (33.32%) disease reduction but Carbendazim 25% + Mancozeb 50 % WS + T. virens showed lowest disease reduction (25.81%).
