Abstract: Tomato, (Solanum lycopersicum), flowering plant of the nightshade family (Solanaceae), cultivated extensively for its edible fruits. Labelled as a vegetable for nutritional purposes, tomatoes are a good source of vitamin C and the phytochemical lycopene. The area under tomato cultivation in Manipur accounts for about 0.15 million hectares with an average production of 2.10 million tonnes and productivity of 12.02 tonnes ha-1 during 2016-17. The major constraints in production of tomato are biotic and abiotic stress. Among the biotic stress Fusarium wilt incurred by Fusarium oxysporum f.sp. lycopersici inflicts tremendous losses to the crop. So the present research was carried out to study in vitro evaluations of native Trichoderma spp., botanicals and fungicides against Fusarium oxysporum causing Fusarium wilt of tomato which induces losses in Manipur. Food poison technique and Dual culture were aided in this investigation. The investigated results revealed that among bio control agents tested Mix (Trichoderma asperellum + Trichoderma harzianum) and Trichoderma asperellum effectively controlled mycelial growth of the pathogen by 80% and 72% respectively. Botanicals used in this study significantly inhibited the growth of the fungus, among which garlic (Allium sativum) gave the best results by showing 75% of inhibition at 10% concentration followed by garlic 5% and ginger 10% showed 60 to 62% inhibition, among fungicides Propiconazole 13.9% + Difenoconazole 13% gave the best results by showing of 100% inhibition at 0.1% concentrations.
