Evaluation of fungicides against Colletotrichum gloeosporioides (Penz.) Penz. and Sacc. the incitant of mango anthracnose

Mango is one of the most important fruit crop of our country and anthracnose is the most important disease causing both pre and post-harvest losses. To manage the disease under field condition we need to use a combination of different fungicides. Hence, in the present study we investigated the efficacy of 14 different fungicides in inhibiting the growth of the Colletotrichum gloeosporioides under in vitro conditions. The result of the study indicated that, out of the 14 fungicides tested, a combi product Flurilazole + Carbendizim 37.5% WP and systemic fungicides Propiconazole 25% WP showed significantly superior inhibition over other fungicides with complete 100 per cent mycelial inhibition and absence of sporulation in all the three concentration i.e, 0.1%, 0.2%, 0.3% tested. Myclobutanil 10% WP showed inhibition of 97.2% followed by Tebuconazole + Trifloxystrobin 75% WG with 94.86% inhibition. Systemic fungicides Difenconazole 25% EC with 85.50% inhibition was on par with combi product Zineb 68% +Hexaconazole 100% WP with 85.06% inhibition.
