Epidemiology and Disease Management of Brown Spot of Rice in India

  • N. K. Chakrabarti
Chapter

Abstract

Rice (Oryza sativa L.) suffers from a number of fungal diseases and many of them occur at times in fairly severe form and cause substantial loss to the crop yield. Among the major fungal diseases of rice, brown spot occupies not only an important position, but also historical interest. The disease is prevalent throughout the rice growing tracts of the world. It is found to be pendemic in heavy rainfall areas viz. the Himalayas, Assam, Malabar coast and West Bengal. Its occurrence has been reported in Asia, Africa, South America and U. S. A. The disease is generally severe in soils of low pH, low available potassium (K2O) and also deficient in essential and trace elements.
