Abstract
Fusarium wilt or vascular wilt of tomato, caused by Fusarium oxysporum f.sp. lycopersici is one of the major constraints in tomato production. A survey
was carried out to assess the incidence and distribution of fusarium wilt in different Agro-climatic zones of Rajasthan in the year 2019-20 and 2020-21 (Figure 1). Total fifty villages of different agro-climatic zones were surveyed involving five fields of every village by counting infected or diseased plants in tomato field
of 5×5 m2 area of randomly selected from four to five places in each field. Highest wilt incidence was recorded in Zone IIIA (28.07%) followed by Zone IVA
(24.02%) while, lowest percent disease incidence was recorded by Zone IVB (21.28%). At districts level, maximum disease incidence was found in Udaipur
(31.08%) followed by Jaipur (28.07%) and Banswara (22.70%). Minimum wilt incidence was observed in Chittorgarh (16.99%) followed by Pratapgarh district
(19.86%). The survey results revealed that disease incidence was noticed causing loss in tomato crop and production.
