Occurrence and Distribution of Cluster Bean Diseases in Grid Region of Madhya Pradesh

Background: Cluster bean [Cyamopsis tetragonoloba (L.) Taub] has a special contribution among the pulse crops and recognized as one of the important commercial crop of arid and semi-arid region. Being a leguminous crop it is a source to replenish nutrients especially nitrogen of the low fertility soils and enhances the soil fertility and also can withstand moisture stress. Various biotic and abiotic constrains in cluster bean were responsible for lowering average yield of crop as compared to its potential yield. Thus, it becomes imperative to sustain the productivity of clusterbean by gathering the information and behavior of disease distribution pattern in the zone. The current study therefore greatly emphasized to find out the occurrence and distribution pattern of diseases in major cluster bean growing areas grid region of northern Madhya Pradesh. Methods: An intensive survey was conducted with an objective to access the prevalence and intensity of diseases of cluster bean in sixteen village of three district of grid region of Madhya Pradesh between 2018-19 and 2019-20. Result: Investigation in respect of survey conducted concludes that alternaria leaf blight, dry root rot and bacterial leaf blight are the major concern diseases of cluster bean which directly affect the yield (Chand and Gandhi, 1978). Alternaria leaf blight (19.90%) and Bacterial leaf blight (11.60%) disease intensity was maximum in Gwalior district while maximum dry root rot (4.25%) incidence was recorded in Morena district.
