Abstract:
The fungicide and bioagents taken in the study could be able to reduce the mycoflora associated with seed and therby increase germination percentages, root and shoot length and ultimately seedling vigor index and also reduction in mortality per cent. Various fungicides and bioagents i.e. carbendazin 50% WP @ 0.1%, thiophanate methyl 70% WP @ 0.1%, carboxin 37.5% + thirum 37.5% WP @ 0.25%, carbendazim 12% + mancozeb 63% WP @ 0.25%, T. asperellum, T. harzianum and T. hamatum were tested against Fusarium oxysporum f. sp. udum in pot. The cultivar ICP-2376 was used for experiment. The maximum seed germination per cent was observed in carboxin 37.5% + thirum 37.5% WP @ 0.25% which recorded 96.90% germination, followed by carbendazim 12% + mancozeb 63% WP @ 0.25% which recorded 93.80% germination. The shoot and root length were ranged between 20.68 to 32.63 cm and 7.52 to 10.51 cm, respectively. The maximum seedling vigour index was observed in carboxin 37.5% + thiram 37.5% WP @ 0.25% which recorded 4180.2. The maximum pre-emergence and post-emergence mortality was observed in control (untreated) which recorded 46.86% and 4.41%, respectively. The maximum fresh and dry weight was observed in carboxin 37.5% + thiram 37.5% WP @ 0.25 which recorded 13.36 g and 4.97 g, respectively.
