Abstract
For most Indian families, rice (Oryza sativa L.) is a nutritious staple. It is also considered India?s and the World?s primary food source. Cultivation of rice in India is confronted with variegated agro-climatic conditions, various soil types, and multiple biotic and abiotic factors. Among the various biotic constraints, blast disease caused by fungi Magnaporthe oryzae (anamorph Pyricularia oryzae) is shown to be responsible for significant yield losses every year. In India, blast epidemic occurs due to various races of the pathogen, resulting in resistance breakdown within a very short period, causing severe damage. The pathogen is an ascomycetes fungi which infect rice seedlings up to the adult stage of the crop. The control can be achieved through several approaches, including cultural, nutritional, chemical, and biocontrol methods. This review paper aims to provide a precise view of the various methods that can be used to control blast diseases caused by M. oryzae (anamorph P. oryzae)..
