Abstract:

Tomato (Solanum lycopersicum Mill.) is one of the most remunerative and widely grown vegetables in the world. 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 Curvularia leaf spot caused by Curvularia spicifera inflicts tremendous losses to the crop. The present research was carried out to study in vitro evaluations of native Trichoderma spp., botanicals and fungicides against Curvularia spicifera causing Curvularia leaf spot 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), Trichoderma viride and Trichoderma asperellum effectively controlled mycelial growth of the pathogen by 55% and 50% respectively. Botanicals used in this study significantly inhibited the growth of the fungus, among which garlic (Allium sativum) gave the best results by showing 73.33% of inhibition at 10% concentration followed by garlic 5% and ginger 10% showed 55.55to 53.86% inhibition, among fungicides Propiconazole 13.9% + Difenoconazole 13% gave the best results by showing of 100% inhibition at 0.1% concentrations.
