Among different production constraints in soybean, the most serious being diseases. These diseases are caused principally by fungi or bacteria however fungal diseases causing greater threat to the crop production. The damage caused by foliar diseases is mostly of minor importance except diseases like soybean rust, Pod blight, Rhizoctonia aerial blight or web blight etc. which can reduce yields when weather conditions favor disease development. Correct identification and early detection are critical in the proper management of soybean diseases. In this review we are discussing about economic importance, symptomatology, causal organism, disease cycle, epidemiology and integrated management of some economically important fungal diseases of soybean viz. Seed and seedling diseases of soybean, Rhizoctonia root rot, Pod blight, Rhizoctonia aerial blight or web blight, Charocal rot, Rust disease and collar rot.

Majority of the leaf spot diseases on soybean crop is caused by different pathogenic fungi. Under favourable conditions and severe infection, it may result in heavy defoliation. It decreases the production efficiency of the crop by reducing the surface area available on leaves for photosynthesis. With less photosynthetic activity, the yield may be reduced significantly. Thus, making it a production constraint by reducing the economic viability of the infected soybean crop. Cercospora leaf spot, Target leaf spot, Alternaria leaf spot, Brown Spot, Phyllosticta leaf spot are the major leaf spots caused due to fungus in the soybean crop worldwide. In this review, we are discussing about economic importance, symptomatology, causal organism, disease cycle, epidemiology and integrated management of leaf spots caused due to fungal infection in the soybean crop.
