Conventional methods of controlling insect pests and phytopathogenic microbes not only contaminate the environment but also affects the economy of the agricultural sector as most of the agrochemicals (insecticide, fungicide etc.) applied are lost in the environment. Moreover, extensive use of agrochemicals leads to contamination of food crops with toxic residue. So there is an urgent need for exploring alternative strategy to address this problem. Development of nanomaterial based slow release agrochemicals can drastically reduce the volume of agrochemicals required for controlling insects and phytopathogens. Dr. Debnath is currently involved in development of silica coated porous zinc oxide nano composite for delivery of fungicides. This nanocarrier has a unique advantage. Nanosilica has entomotoxic property and nano zinc oxide has antimicrobial property. So not only the cargo but also the carrier will provide plant protection.

As always, my primary aim in teaching is students’ participation through interaction during and beyond scheduled class hours. Classes are made more interesting with audio-visual aids, industry and research lab visits. As I have my own research lab I take summer project students from our department to motivate students in research.
