Abstract
Rice is one of the major food crops in South-Eastern India. Its production was severely affected by certain agro climatic conditions such as biotic and abiotic stresses in crop health. Biotic stress such as fungi, bacteria, nematodes, viruses and non parasitic disorders are involved. Among which the fungal diseases, rice blast is considered one of the most important diseases of rice. Rice blast caused by Magnaporthe grisea is turn to be one of the most severe pathogen under change in climatic condition. Asian countries are main rice producer as well as consumer of world 90% production. This disease can be efficiently managed by following management practices viz. cultural, biological and chemical methods.
