Molecular Characterization and Biocontrol Potential of Native Rhizobacteria Against Rhizoctonia solani in Rice

Screening 32 native soil bacteria from Karnataka rice fields, researchers found two Streptomyces strains that cut sheath blight severity as effectively as a chemical fungicide — with hydrogen cyanide and iron-starving siderophores identified as their weapons against the fungus.

The Soil Bacteria That Fight Rice Disease as Well as a Fungicide

Researchers in Karnataka screened 32 native soil bacteria pulled straight from healthy rice fields and found two that matched a chemical fungicide's performance against sheath blight — by starving the fungus of iron and choking its ability to make energy.
