In vitro evaluation of fungicides against foliar fungal pathogens of greengram

Laboratory evaluation of different fungicides against foliar fungal pathogens of greengram revealed that hexaconazole 5 EC (0.1% and 0.15%), carbendazim (25%) + mancozeb (50%) WS (0.05, 0.1 and 0.2%) or mancozeb 75 WP (at 0.1, 0.2 and 0.25%) and propiconazole 25 EC, trifloxystrobin (25%) + tebuconazole (50%) w/w (at 0.05, 0.1 and 0.15%) or copper oxychloride 50 WP (at 0.25%) resulted into 100 per cent inhibition of mycelial growth of Cercospora canescens and Colletotrichum gloeosporioides, respectively. Copper oxychloride showed submerged growth under poisoned food technique. The slide germination bioassay of fungicides against Erysiphe polygoni revealed cent per cent inhibition of conidial germination with hexaconazole 5 EC and azoxystrobin (250%) SC at 0.15 per cent.
