Brinjal or eggplant (Solanum melongena L.) belongs to family Solanaceae and is recognized as vegetable crop yielding plant and grown throughout the tropical, sub-tropical and warm temperate areas of the world. Various biotic and abiotic constrains in brinjal crop were responsible for lowering average yield of crop as compared to its potential yield. Thus, it becomes imperative to sustain the productivity of brinjal by gathering the information and behavior of disease distribution pattern in the northern region of M.P. The current study therefore greatly emphasized to find out the prevalence and distribution pattern of diseases in major brinjal growing areas northern Madhya Pradesh. An intensive survey was conducted with an objective to access the prevalence and intensity of Alternaria leaf spot of brinjal in one hundred eight sites of seven district of northern region of Madhya Pradesh between 2021-22 and 2022-23. Two year mean data clearly indicates that the maximum percent disease intensity was recorded in Guna (17.20%), followed by Ashoknagar (16.20%), Shivpuri (15.23%), Gwalior (10.63%), Bhind (10.00%), and Sheopur (6.85%). Morena (6.53%) recorded minimum percent disease intensity of Alternaria leaf spot of brinjal.
