Efficacy of different fungicides by in vitro against Colletotrichum gloeosporioides, the causal agent of mango anthracnose

Abstract

The cultivation of mango is found to be increased due to its high income and nutritive value. The crop is widely grown throughout the world. Productivity of mango is decreased due to various biotic and abiotic stresses. Among biotic, anthracnose is the fungal disease infecting in both field and storage with an economical loss to the tune of 15-20 per cent so that management through fungicides is the necessary practice to reduce the loss. In laboratory condition different fungicides were tested against Colletotrichum gloeosporioides by using poison food technique. Among systemic fungicides viz., difenconazole 25% EC, propiconazole 25% EC and tebuconazole 25% EC completely inhibited the growth of fungus while in non-systemic fungicides propieb 70% WP significantly inhibited the fungus and among combi-fungicides tryfloxystrobin 25% + tebuconazole 50% was successful by completely inhibiting the growth of C. gloeosporioides at all the three tested concentrations.
