Abstract
Ten different contact, systemic and combination products of fungicides were evaluated for their effectiveness against black spot of papaya Asperisporium caricae under in vitro condition by following poisoned food technique. Among fungicides tested, trifloxystrobin 25% + tebuconazole 50% WG, propiconzole 25% EC and zineb 68% + hexaconazole 4% WP were successful in completely (100%) inhibiting the growth of A. caricae at all concentrations (50,100, 250, 500, 750, 1000 ppm) which is followed by hexaconazole 25% EC, difenconazole 25% EC, zineb 68% hexaconazole 4% WP completely inhibited the growth of the fungus at 500 ppm and above concentration. Least inhibition of fungal growth was recorded in copper oxychloride 50% WP at all concentrations. Trifloxystrobin 25% + tebuconazole 50% WG, propiconazole 25% EC and zineb 68% + hexaconzole 4% WP were most effective which completely inhibited the spore germination at all concentrations, while the copper oxychloride 50% WP was recorded the least per cent inhibition of fungal spores.
