Rice, Integrated Disease Management, Disease, Viruses


Rice (Oryza sativa L.) is a one of the most important staple food crops of the world nearly half of the world population depends on rice. Rice play an important role in global food security, it is prone to attack by many diseases caused by plant pathogens such as, fungi, bacteria viruses and nematodes. Among diseases, rice blast, bacterial leaf blight, brown leaf spot, sheath blight, sheath rot, stem rot, false smut, rice tungro virus and rice root-knot nemato deare economically important and they cause huge economic losses. Recently, due to change in the global temperature and change in climatic situation minor diseases are becoming major (false smut of rice and rice root-knot nematode), The various methods used for managing rice disease includes, use of resistant varieties, cultural practices, biological and chemical control. All these methods have varied degrees of success in managing rice diseases. The most important management tactics used worldwide includes use of resistant varieties and chemical control. Integration of all the management tactics (Integrated Disease Management) could help in effective and successful management of plant disease in rice. In this chapter we are showcasing the important diseases of rice, global distribution, economic importance and management strategies.
