ABSTRACT: Thirty five fungal species, representing 20 genera were found to be associated with BpLB infected leaves of twenty one wheat varieties, collected from eight districts (Dhaka, Gazipur, Dinajpur, Joypurhat, Pabna, Sirajgonj, Kushtia and Chuadanga) of Bangladesh. The most predominant fungi, in order of prevalence, were Alternaria alternata, Bipolaris sorokiniana, Cladosporium cladosporioides, Curvularia lunata, and Fusarium semitectum. The fungi varied in prevalence with respect to location, cultivar and year. Among the 35 fungi, association of Bipolaris cynodontis with wheat is a new record.
