AB  - Rice blast caused by <i>M. oryzae</i> is one of the
most devastating fungal disease of rice in the world. The
crop suffers from the chronic fungal pathogen from
seedling to adult plant stages affecting leaves, collar,
node, panicle, neck, roots, seeds, etc. The main objectives
of this review paper is to know the symptoms of rice blast
disease, its epidemics and diffferent measures of effective
disease control. Resistant varieties and chemical control
are most effective means of disease control. Findings
shows >100 resistant genes and 350 quantative trait loci&#146;s
for blast resistant has been identified in rice. Extensively
used persistant chemicals should replaced by Neem based
commercial pesticides and biocontrol agents like
<em>Pseudomonas fluorescens, Streptomyces</em> for sustainable
and ecofriendly control of rice blast havoc. Disease
forecasting methods developed by researchers provides
pre-information of disease occurrence that helps to design
control measures combination for effective management
of the disease.
