Abstract: Tomato (Solanum lycopersicum L) is most remunerative vegetable crop. It is infected by several pathogen among them early blight most devastating disease is considered to be a great threat to its production world widely. Assessment of disease severity is an important step and it helps in designing management strategies which help in increasing the crop yield. Therefore, a survey was conducted in tomato growing areas of different tehsils viz., Tinwari, Bilara, Bhopalgarh, Osian and Bawadi of Jodhpur district, Rajasthan during kharif 2020 to assess the intensity of early blight diseases. Among them the highest intensity of early blight of tomato was observed in Tinwari tehsil (32.35 %) followed by Osian (28.25%). Whereas, the minimum early blight intensity was observed in Bilara (12.04 %) tehsil. The overall average disease incidence of the Jodhpur district was (23.10 %) based on total 125 fields surveyed in kharif 2020.
