Abstract:


Crop protection against insect pest is a priority and due to the adverse impact of chemical insecticides, use of biopesticdes is increasing. Bacillus thuringiensis (Bt) based biopesticides have utmost importance and occupy almost 97% of the world biopesticide market. Environmental contamination, food safety concerns, and pest resistance to conventional insecticides have caused a steady increase in demand for Bt-based insecticides. Despite extensive research in the field of Bt biopesticides, many formulations don’t deliver effectively in field owing to various environmental stresses (for example agriculture and forestry). Insecticides formulated with Bt account for less than 1% of the total insecticides used each year worldwide because of high cost, narrow host range, and comparatively low efficacy. The recent escalation of commercial interest in Bt has resulted in more persistent and efficacious formulations. In this context, nanotech applications and products are strongly promoted on the basis of their environmental benefits. Bt as NANOPARTICLES in agriculture especially for plant protection is an under explored area, and needs further exploration. This short concept note discussed on various aspects of Bt as nanoparticles covering the prospect, integration and future strategies for the effective utilization to the benefits of human welfare.
