Biological and Molecular control of blast disease in Oryza sativa L.
Rice blast disease can be perfectly controlled up to 40-80 % by use of varied fungicides especially in the temperate and subtropical paddy growing areas of the world. Applications of synthetic chemical fungicides are environmentally hazardous and unsuitable in controlling Magnaporthe oryzae whereas naturally occurring biofungicides with multiple modes of actions are needed to be discovered for combatting the blast fungus.
