Efficacy of Fungicides against Anthracnose of Green Gram Caused by Colletotrichum lindemuthianum

Abstract— Green gram (Vigna radiata L.) is autogamous diploid grain legume crop belonging to Leguminosae family. Anthracnose caused by Colletotrichum lindemuthianum is a serious disease in almost all green gram growing areas. Five systemic, five non-systemic and five ready mixed fungicides were evaluated against C. lindemuthianum under in vitro by poison food technique. Among the systemic fungicides, highest mean inhibition of mycelial growth obtained with tebuconazole (100%) followed by carbendazim (78.33%) and difenoconazole (75.18%). Among the non-systemic fungicides, highest mean mycelial growth inhibition was obtained by copper oxychloride with 100 per cent followed by mancozeb with 84.62 per cent. Among ready mixed fungicides, carbendazim + mancozeb and tebuconazole + trifloxystrobin were significantly higher than the rest of the ready mixed fungicides with 100 per cent mycelial growth inhibition followed by azoxystrobin + difenoconazole and captan + hexaconazole with percentage of 95.37 and 83.42, respectively.
