In-vitro Evaluation of Different Fungicides against Black Leaf Spot Causing Fungus Asperisporium caricae in Papaya

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