Abstract

A bacterium strain B196,isolated from the rice plants,could inhibit the growth of Rhizoctonia solani.According to its morphological,physiological and biochemical characteristics and 16S rDNA sequence analysis,the strain B196 was identified as Bacillus megaterium.This strain could colonize in rice plants after inoculating with seed dipping and spraying.Control effect of strain B196 on rice sheath blight was 64.29% in pot and 55.13% in fields.
