In vitro evaluation of different fungicides against Colletotrichum gloeosporioides causing anthracnose of pomegranate

Abstract

In vitro evaluation of new synthetic fungicides against Colletotrichum gloeosporioides were carried out in the Department of Plant Pathology, College of Agriculture, Osmanabad during the year 2011-12. Among the non-systemic fungicides at 0.3 per cent concentration carbendazim + mancozeb showed 82.10 per cent inhibition of mycelial growth of fungus followed by chlorothalonil with 75.80 per cent and least inhibition of mycelial growth was recorded in captan 63.48 per cent. The systemic fungicides were evaluated against the pathogen at 0.05, 0.1, 0.15 per cent concentration. Among these concentration all fungicides were significantly found superior at 0.15 per cent concentration compared to 0.1 and 0.05 per cent concentration. The maximum per cent inhibition of growth of C. gloeosporioides was observed in propiconazole (74.86%) followed by benomyl (68.17%), iprodion + carbendezim (67.67%), thiophynate methyl (64.97%). The least per cent inhibition of fungus was recorded in bittertanol (44.12%) and hexaconazole (32.62%).

In vitro evaluation of different fungicides against pomegranate anthracnose caused by Colletotrichum gloeosporioides

“…Ranjitha et al (2019) [14] also recorded that the mycelial inhibition of C. gloeosporioides by tebuconazole + trifloxystrobin and zineb + hexaconazole was 94.86% and 85.06%, respectivey. On contrary with our results Prashanth et al (2008) [13] , Krishnappa (2010) [8] and Jagtap et al (2015b) [7] recorded maximum inhibition with carbendazim 12% + mancozeb 63% WP. There was positive correlation between concentration and inhibition of growth of pathogen.…”

“…Carbendazim proved to be the second best fungicide against C. gloeosporoides. Efficacy of carbendazim and different triazoles including hexaconazole has also been reported against C. gloeosporoides by Jagtap et al (2015); Tasiwal et al (2009).…”
