Abstract: Five contact fungicides, four systemic fungicides and four combiproduct fungicides were evaluated for their effectiveness against A. caricae under in vitro condition by following poisoned food technique. Among contact fungicide tested Mancozeb 75% WP (44.35%) showed maximum and Copper hydroxide 50% WP (24.03) showed least inhibition of radial mycelial growth. Carbendazim 50% WP and Propiconazole 25% EC showed complete mycelial inhibition among the four systemic fungicide evaluated whereas, least inhibition was reported on Hexaconazole 5% EC (38.33%). Among the combiproduct fungicides used in the treatment to evaluate their efficacy against A. caricae 100% inhibition was obtained by (Carbendazim 12% + Mancozeb 63%) 75% WP and Picoxystrobin 7% + Propiconazole 12% SC whereas, Metiram 5% + Pyrachlostrobin 55% WG (21.60%) imparted minimum mycelial growth inhibition.
