Research Interests

My research involves exploring microbes from different niches such as endophytes from wild plant varieties, pesticide contaminated agricultural fields, Farmer’s fields infested with pathogens and arsenic contaminated soil samples, fortheir application inpromoting sustainable agriculture and environment.Understanding the mechanisms of microbes mediated abiotic and biotic stress tolerance in plants,and development of microbes based technologies to solve farmer and field centric problems are the thrust areas of my work.

Research Summary

Basic Research

My team is workingin the area of biological control of fungal pathogens using endophytes and Trichoderma in agronomically important crops such as Gladiolus, betelvine, rice and tomato. The team is currently studying the mechanisms involved in rapid spread of fungal diseases in Gladiolus plants and the role of endophytes in biological control of fungal diseases. We are also deciphering the stress tolerance and phosphate solubilization mechanisms in Trichodermausing molecular, biochemical and microscopic approaches.


Applied Research

My team is working to develop microbes based technology / products to addressagriculture centric problems related control of Fusarium in Gladiolus, mitigation of arsenic uptake in chickpea and rice crops and developing alternative techniques for agri-waste management. Bacillus subtilis strain NBRI-W9 has been developed as a potent Biological Control agent against Fusarium diseases in betel-vine and Gladiolus. A Trichoderma spp. based consortium has been developed for efficient utilization of residual rice straw and a product called “Tricho-straw pellet” has been developed. The product is useful for sodic soil reclamation and improvement of soil organic carbon. A low cost technology for Trichoderma production has been developed and filed for patent.
