Abstract:
Pigeonpea wilt disease caused by Fusarium oxysporum f. sp. udum is one of the most devastating soil-borne disease. The aim of present investigation was to evaluate the antifungal activities of fungicides which can be used to control wilt disease of pigeonpea. The systemic fungicides viz. azoxystrobin, hexaconazole, penconazole, propiconazole, thiophanate methyl, difenconazole, carbendazim and fosetyl-AL and combi fungicides viz. carbendazim 25% + mancozeb 50 % WP, carbendazim 12 % + mancozeb 63 % WP, hexaconazole 4 % + zineb 68 % WP, hexaconazole 5 % + captan 70 % WP and metalaxyl M 4 % + mancozeb 64 % WP screened in vitro for their antifungal activities against F. udum by using poison food techniques. Among eight systemic fungicides tested, per cent average mycelial growth inhibition was ranged from 79.75 to 100 per cent. However, it was cent per cent in azoxystrobin, hexaconazole, penconazole and propiconazole (100 %), followed by thiophanate methyl (97.90 %), difenconazole (93.70 %), carbendazim (89.38 %) and fosetyl-AL (90.74 %). Among five combi fungicides tested per cent average mycelial growth inhibition was ranged from from 62 to 92.13 per cent. However, it was highest average mycelial growth inhibition in carbendazim 25% + mancozeb 50 % WP (92.13 %), followed by carbendazim 12 % + mancozeb 63 % WP (83.15 %), hexaconazole 4 % + zineb 68 % WP (78.15), hexaconazole 5 % + captan 70 % WP (76.39 %) and metalaxyl M 4 % + mancozeb 64 % WP (62.69 %).
