Evaluation of Fungicides and Botanicals against Mango (Mangifera indica) Anthracnose

Mango anthracnose disease caused severe damage to mango yield so its control is required. For this purpose the current investigation was carried out under in vitro and under field conditions during, 2016 at CCS, HAU, Hisar. The experiment was carried out through poison food technique under in vitro and through foliar spray under field conditions. Five fungicides along with three botanicals were evaluated in vitro against Colletotrichum gloeosporioides, the causal agent of anthracnose disease of mango. Carbendazim completely inhibited mycelial growth up to 100 per cent. Copper oxychloride was found least effective among all five fungicides. Among botanicals eucalyptus leaf extract was found most effective in inhibition of fungal growth up to 58.5 and 70.4 per cent at 5 and 10 per cent concentration, respectively. Neem leaf extract at 10 per cent concentration inhibited mycelial growth up to 57.0 percent. The best performing in vitro two fungicides and two botanicals when tested under field condition, carbendazim (0.1%) twice at 15 and 30 DAI (days after initiation) of disease was found most effective in controlling the disease up to 71.43 per cent and 65.22 per cent in Langra and Dashehari cultivars, respectively.
