Management of anthracnose (Vigna radiata (L.) Wilczek] caused by Colletotricum gleosporiodes (Penz.) Penz. & Sacc.) disease in green gram through ready-mix fungicides under field conditions

Abstract

As a result of fungal diseases, green gram is prone to powdery mildew, anthracnose, cercospora leaf spot, and dry root rot. The one that has the most influence on the economy is anthracnose, which is caused by Colletotricum gleosporiodes (Penz.) Penz. & Sacc. The most important aspect of the study was the evaluation of fungicides, including Carbendazim 12%+ Mancozeb 63% WP, azoxystrobin 18.2%+ difenoconazole in three different concentrations to manage anthracnose under field conditions in 2020–2021 and 2021–2022, along with CIB recommended check metiram 55%+ pyraclostrobin 5% WG. According to the findings, treatment T3 carbandazim 12% + mancozeb 63% 75 WP, 0.133%, had the lowest disease intensity of 11.84 and the highest disease control of 70.72, followed by T6 azoxystrobin 18% + difenoconazole 11.4% SC, 0.133% (17.43 DI), T7 (metiram 55%) + pyraclostrobin 5% WG, 0.30% (20.15 DI), and T2 (20.92 DI). Treatments T1 (carbendazim 12%+ mancozeb 63% WP, 0.066%), T4 (azoxystrobin 18.2% + difenoconazole 11.4% SC, 0.066%), and T5 (azoxystrobin 18.2%+ difenoconazole 11.4% SC, 0.010%) all achieved parity with disease control of 26.80, 27.49, and 28.08, respectively. The maximum illness intensity in the control group was 40.44.
