After green revolution, new varieties of wheat were introduced and some minor disease become occupied the place of major diseases. Bipolaris sorokinina (sacc.)shoem, the causal agent of Spot blotch of wheat, become more prevalent in warmer region of the world and shows symptoms on leaves, spikes, grains and seeds. Bipolaris sorokiniana showed wide host range which lead to the spread of this disease into different host too. About 30-86 percentage of yield loss were reported due to this pathogen. So the management strategies of spot blotch found a special attention at present. Conventional practices like cultural, biological as well as chemical methods are showing positive response to the control of this disease. In this review, we have mainly focused on new trends in disease Management such as use of botanicals, developments of resistant varieties and molecular level of managements. Diagnostic PCR assay are helpful to analyse the disease in field soil and wheat leaves also. Although number of practices made to detect and control this diseases, a base level detection at fields are yet to be find out.
