Abstract

Early blight, being the most devastating disease of tomato (Solanum lycopersicum L.) is considered to be a great threat to its production world widely. This disease is caused by several species of Alternaria and has been observed in all districts of Hadoti region of Rajasthan namely Kota, Bundi, Baran and Jhalawar. Assessment of disease severity is an important step as it helps in designing management strategies which ultimately help in increasing the crop yield. Therefore, a roving survey was conducted to find out the disease severity of tomato blightin foresaid region. The disease was prevalent in all the tomato growing areas during rabi 2019-2020. Percent disease index (PDI) was recorded to be highest in Kota district (44.06 %) followed by Baran, Bundi and Jhalawar (38.08 %) irrespective of cultivars grown. Charchoma village of Kota district recorded highest PDI (49.98 %) while, lowest PDI was recorded in Azampur village of Jhalawar district (34.34). Further, the pathogenic species
