In vitro evaluation of fungicides against Colletotrichum gloeosporioides (Penz.) Penz and Sacc. causing anthracnose of pomegranate (Punica granatum L.)

Pomegranate (Punica granatum L.) is a widely grown fruit in many regions of the world. Anthracnose of pomegranate is one of the limiting factor for low productivity and also the low market price. Therefore, the management of anthracnose disease is necessary. In this study new fungicide molecules are evaluated under in vitro condition against the mycelial growth of Colletotrichum gloeosporioides. In vitro screening of fungicides against C. gloeosporioides showed two combination product Hexaconazole + Zineb, Trifloxystrobin + Tebuconazole and a nonsystemic fungicide Captan showed cent percent inhibition at 100, 250, 500 and 1000 ppm concentration. Similarly, systemic fungicides Hexaconazole, Propiconazole, Penconazole, Tebuconazole and Carbendazim showed cent percent mycelial inhibition at 500, 1000 and 2000 ppm concentrations.
