dc.description.abstractMungbean [Vigna radiata (L.) Wilczek] is an important short duration summer food legume in the tropical and sub-tropical countries of the world. In India, mungbean is cultivated in three different seasons’ viz., Kharif (July- Oct), Rabi (Sept- Dec) and Zaid or summer (March- June). This crop cultivated extensively in Bundelkhand region of Uttar Pradesh. Mungbean is consumed as whole grains as well as dal in a variety of ways in homes and it has wider adaptability and low input requirement. It is a highly nutritious source of proteins and calories in the Asian diet and its green pods contain high level of vitamins and minerals. Despite the multifaceted importance of this crop, its production could not be stabilized in the Uttar Pradesh as well as in the country. This crop is affected by several biotic constraints like diseases and insect-pests hampering its production. Among the diseases, anthracnose disease caused by Colletotrichum lindemuthianum is one of the most important fungal diseases of mungbean. Anthracnose disease appears during warm and humid weather leading to necrosis, defoliation and low yield. Keeping in view of importance of disease, experiments were conducted to isolation and identification of pathogen and to find out the efficient management strategies for this disease. The colony of isolated pathogen C. lindemuthianum onto potato dextrose agar medium was appeared cream to blackish grey, margin regular and immersed. The mycelium of was white initially, but developed dark black colour in advanced stage and grew rapidly. The hypha was septate and white to dark in colour. The conidia measuring 20.20-21.40 x 3.3-3.5μm were hyaline single celled, dumbbell shaped born in acervuli bearing setae. The healthy plants inoculated with pathogen showed dark brown to black sunken lesions on leaves, mostly adjacent to veins; which later become greyish white centre with dark brown or reddish margin. Twice sprays of Carbendazim at 1st appearance of symptoms and 15 days interval gave the maximum reduction in anthracnose incidence and severity i.e. 51.12% and 64.56%, respectively along with significant enhancement (53.39%) in seed yield (quintal/ha) as well as in yield components (except number of primary branches per plant and number of seed per pod) over the unprotected crop during both of the crop seasons i.e. Kharif 2019 and 2020. It was followed by the twice sprays of Carbendazim + Mancozeb or Tebuconazole with respective parameters. Sprays of Captan + Hexaconazole were found to be least effective to reduce the disease incidence/ severity as well as to increase the yield and its components. Out of 190 mungbean genotypes evaluated against anthracnose disease during two consecutive crop seasons, four genotypes viz., Pairy Mung, PMG-991, MGG-295 and Kopargaon were found to be moderately resistant against anthracnose disease.en_US
