Abstract: The spot blotch disease caused by Bipolaris sorokiniana (Sacc.) Shoem is one of the most important foliage disease of wheat crop. This disease appears in almost all wheat growing areas of the world. In Northern part of west Bengal this disease causes severe yield loss every year. For the management of spot blotch disease of wheat five chemical fungicides was used. Plant disease intensity decreased with the application of different treatment over untreated control.The lowest AUDPC was recorded in T4 (Propiconazole@ 1ml/l)260.8 followed by T5 (Tebuconazole@1ml/l) 293.21 and T3 (Carbendazim+Mancozeb @) 2.5g/l) 376.54. Maximum AUDPC was recorded (563.27) under T1 (Untreated/control). Due to the application of Propiconazole, spot blotch disease reduce up to 60.18% and increase chlorophyll contain of the plant, increase different morphological traits of wheat crop as well as also ultimately increase yield up to 35.02%.
