: Type: ARTICLE Literature: oryza Field: abstract Doc ID: pub00000000 Accession (PMID): 00000000 Matching Sentences: [ Sen. 0, subscore: 0.00 ]: A lack of effective , easily applied and stable formulation has been a major obstacle to widespread use of biocontrol agents for control of rice sheath blight . In this study , effervescent fast-disintegrating granules containing endospores of Bacillus megaterium were developed for use either by broadcast or spray application . The formulation composed of lactose , polyvinyl pyrrolidone K-00 ( PVP , K-00 ) and effervescent base ( citric acid , tartaric acid and sodium bicarbonate ) . The number of living bacteria in effervescent granules that performed mycelial growth inhibition was in the range of 00 ( 0 ) CFU/g after 00 months storage at room temperature . The number of viable bacteria after applying into the water and spraying on the rice seedling for 0 days in the greenhouse tests were also satisfactory high ( 00 ( 0 ) CFU/g of granules and 00 ( 0 ) CFU/g of plant , respectively ) . The scanning electron microscope ( SEM ) was used to observe bacterial antagonist on the surface of leaf sheath and leaf blade after spraying with formulation .
