Bipolaris sorokiniana causing spot blotch of wheat produces toxins, which play role in pathogenicity. The isolates of B. sorokiniana differed in their pathogenicity. The profiles of toxin isolated from BS-25 (most virulent isolate) and BS-7 (least virulent isolate) differed on TLC plate; indicating qualitative and quantitative differences. These two isolates were also differentiated on a set of wheat differential lines. Isolate BS-25 showed lowest average infection index (9.6) on genotype Sanghai 4 whereas isolate BS-7 showed 4.9 infection index on the same genotype. With crude toxin symptoms like chlorosis and necrosis on leaf were developed. The toxin from BS-25 produced severe to mild water soaking symptoms on the infiltrated leaf tissue, of Agra local.
