Abstract Intensive use of agrochemicals for crop protection contributes to environmental pollution, in particular water, food and soil. Moreover, over the period of time, pathogenic microbes develop resistance against such chemical thus effectiveness become lower. Therefore, it is required either to develop the effective antimicrobial agent that can release slowly and in a controlled fashion or resistance in the plants against the pathogenic organism. In the present investigation, we synthesized chitosan (diameter between 200 and 370 nm) decorated with inorganic (i.e Cu) or organic (i.e. salicylic acid) substances. We characterized the engineered chitosan for its stability and physicochemical properties. Further, the chitosan formulation tested on corn and tomato. The formulation was delivered to these plants by a foliar aerosol spray. Resultant we observed that the functionalized chitosan nanoparticles boost the plant resistance by altering reactive oxygen species or mobilizing reserve food. The predictable role of engineered chitosan in plants might be in achieving sustainable plant growth through boosting the intrinsic potential of plants. In-spite of the fact that engineered chitosan abode immense biological activities in plants, these materials have not yet been widely adopted in agriculture due to poor understanding of its bioactivity and modes of action towards pathogenic microbes and in plant protection and growth. Our findings not only highlighted in-depth, various engineered chitosan formulation which has been tested for plant growth and protection mainly against fungi, bacteria and virus but also explained their modes of action.
