Abstract
AbstractBipolaris sorokiniana (Teleomorph: Cochliobolus sativus), causal agent of spot blotch of wheat, emerges as a serious concern for yield losses to wheat crop in warm and humid regions of the world. Due to global warming and late sowing of wheat crop, spot blotch becomes a major concern worldwide. Spot blotch mainly occurs in North eastern plain zone in India as well as in other South Asian countries. To meet escalating demand of wheat crop in near future due to increasing global population growth rate and nutritive changes, management of this disease is necessary. This review summarizes the biology of the pathogen (Bipolaris sorokiniana) and an overview of distribution, impact, and management of the disease. In addition, it also provides insights into wheat—B. sorokiniana pathosystem at histological and molecular level. There are several approaches for the management of spot blotch disease, by way of identifying QTLs (quantitative trait loci) for spot blotch resistance, exercising marker-assisted selection and integrated approaches such as agronomic practices, proper crop rotation, biological control, and seed treatment with fungicides.Keywords Bipolaris sorokiniana Spot blotchBiologyHost–pathogen interactionManagementWheat
