Tea garden soil harbors several microorganisms that help in maintaining the crop agro-ecosystem. Some soil microorganisms are beneficial and some may cause harm. The beneficial entomopathogenic fungus (BPA/B7) isolated from Tinsukia (Assam) was found to be more effective against Helopeltis theivora Waterhouse compared to other strains of Beauveria bassiana. This pathogenic fungus has been mass produced and formulated into powder and liquid formulation and its different properties have been screened under laboratory and field conditions and both the formulations were found to be effective against H. theivora.
