This study, which examines the management of Cercospora leaf spot disease in Urdbean, contributes to the benefit of agriculture by preventing the occurrence of plant diseases. The purpose of this study was to look into how various fungicides affected the management of Cercospora leaf spot in Urdbean. During the Kharif season of 2023, the study was conducted at the Rainfed Organic Agriculture Research Farm Narayan Bagh, which is part of the Department of Plant Pathology at the Institute of Agricultural Sciences, Bundelkhand University, Jhansi (Utter Pradesh). The experiment was laid out in a randomized block design (RBD) with three replications. Fungicides were foliar applied after the initiation of the disease. Results showed that among the tested treatments, including the control, carbendazim 50% WP @ 0.10 g/L (86.77%), followed by Trichoderma harzianum 1% WP @ 10 g/L (18.33%), propineb 70% WP @ 0.15 % (19.53%), propiconazole 25% WP @ 0.10 g/L (20.43%), Trichoderma + Pseudomonas @ 0.10 g/L (22.27 %), chlorothalonil 75% WP @ 0.15 % (23.60%), mancozeb 75% WP @ 0.20 % (24.50%), and Pseudomonas fluorescens 1% WP @ 10 g/L (33.27 %), they were significantly superior over control.
