Abstract:

Soybean rust caused by the biotrophic fungus Phakopsora pachyrhizi, is one of the major detrimental global concerns and the most challenging foliar diseases of soybean (Glycine max) production worldwide. The pathogen is able to survive all year‑round attributable to its polycyclic nature if a host is available and favorable conditions for soybean production are also fortunate for epidemics. This review focuses primarily on economic importance, epidemiology and management strategy of soybean rust (Phakopsora pachyrhizi). It is responsible for significant yield reduction up to 90% depending on prevailing weather patterns and the wide distribution of the pathogen makes it the most harmful disease in soybeans production worldwide. Now a days, substantial progress has been made towards understanding the epidemiology, identification of sources of resistance and mapping of soybean loci conferring resistance to Phakopsora pachyrhizi since this species is particularly well established and widespread. Besides, host-plant resistance is mainly considered as the most looked for solution from an environmental, economic and cost effective. Furthermore, other disease control approaches such as cultural practices and chemical application are also important and influence rust epidemiology as well as the durability of host plant resistance. Reviews summarize the research in the following areas; a management practices that uses fungicides effectively will afford the primary tool, which in time will hopefully be complemented by some form of host resistance. Development of resistance to fungicides and its ability to overwhelmed resistance genes show that no single management practices will be able to maintain the sustainability of the crop. To sidestep the destruction and yield losses, all management practices must be associated in the form of integrated management.
