Abstract: In vitro study was carried out to check the efficacy of seed treatment by fungicides on the seed germination and seedling vigour by controlling the most dominant seed mycoflora of chilli variety GVC 101 was carried out by paper towel method. Seed treatment with carbendazim + mancozeb @ 2.50g/kg seeds found most effective with significantly higher seed germination and seed health parameters for GVC 101 seeds pretreated with A. niger. Seed treatment with metalaxyl + mancozeb @ 3.50g/kg seeds found most effective with significantly higher seed germination and seed health parameters for GVC 101 seeds pretreated with Colletotrichum sp. Whereas, in seeds pretreated with Fusarium sp., significantly higher seed germination and seed health parameters were recorded in seed treatment with metalaxyl + mancozeb @ 3.50g/kg seeds seeds for GVC 101. Captan and metalaxyl + mancozeb were found very effective in controlling or inhibiting the growth of most dominant seed infecting fungi of chilli. It was also noticed that all the seeds treated with tebuconazole @ 1.5g/kg seeds resulted in cent per cent inhibition in seed germination. This indicates toxic effect of tebuconazole @ 1.5g/kg seeds and at higher dose on chilli seeds.
