Diagnosis and Management Strategies for Soybean Diseases

Soybean is one of the most important oilseed crops cultivated in tropical and subtropical regions of the world since ancient times. The productivity of soybeans is affected by several abiotic and biotic constraints, which include diseases caused by fungi, bacteria, and viruses. The most important diseases of soybean include anthracnose, pod blight, charcoal rot, Rhizoctonia aerial blight, bacterial blight, damping off, seedling rot and blight, yellow mosaic virus, soybean mosaic, frogeye leaf spot, etc., which can affect yield if environmental conditions favor disease growth. The correct management of diseases depends on accurate identification and early detection. The economic significance, symptomatology, causal organism, disease cycle, epidemiology, and management of a few economically significant diseases of soybean are all covered in this chapter. It takes into account the main diseases of soybean and pathogens affecting agricultural productivity, as well as new emerging threats.
