Abstract: Different fungicides and botanicals were evaluated for their effect on seed germination, seed vigour and viability of sclerotia admixtured with moongbean seeds. Among various fungicides tested in vitro condition, Vitavax power (Carboxin 37.5% + Thiram 37.5% WS) 3gm/Kg seed, Azoxystrobin 23% SC 2ml/Kg seed and Adexar (fluxapyroxad 62.5 g/l + epoxiconazole 62.5 g/l) 2ml/Kg seed gave 100 per cent suppression of mycelial growth from sclerotia of R. solani even after 72 hours of incubation. Like wise different botanical extracts were tested at 10% concentration. Thuja gave best results as compared to others. In case of both in vitro and in vivo evaluation of fungicidal and botanical seed treatment on seedling germination and plant vigour of moongbean Vitavax power (Carboxin 37.5% + Thiram 37.5% WS) and Carbendazim respectively gave highest germination per cent and vigour index among all the fungicides while in case of botanicals Neem was found most effective under in vitro condition with 100 per cent germination and highest vigour index (1643.3) and Thuja was found significantly superior in order to germination per cent (93.33%) and vigour index (1353.29) under in vivo condition.
