Biography
Developed a formulation of Bacillus megaterium (NBAII 63) for the management of bacterial wilt disease of brinjal and tomato Developed a bacterial consortium for the management of capsule and rhizome rot disease of cardamom. Microbial mechanism of insecticide resistance in insects was explored. Characterized the non pathogenic gut microflora associated with leafhoppers (Amrasca biguttula biguttula, Nilaparvata lugens, Empoasca spp., Nephotettix nigropictus, Bothrogonia spp.) in India. Role of gut microflora of Amrasca biguttula biguttula in insecticide degradation was confirmed first time in the country. Characterized the fungal symbiont associated with Tea shot Hole Borer Euwallaceae fornicatus
Research Interest
