Abstract
Rising awareness of the risks regarding chemical formulations and the surging need for eco-friendly inputs in sustainable agriculture have driven the use of bacterial biocontrol agents to the frontline of plant protection. Bacterial biocontrol agents (BBCAs) have been preferred as feasible alternatives to synthetic formulations due to their increased specificity and safety. Nanotechnology has facilitated the better addressing of product development and performance concerns related to BBCAs. Leveraging nanotechnology in the synthesis of novel nanomaterials with amended properties at the nanoscale has offered efficient and ecologically sound nanoformulations such as nanobiopesticides. The nanobiopesticides of bacterial origin, known as bacteria premised nanobiopesticides (B-NBPs), are efficient alternatives to agrochemicals. The B-NBPs include living or nonliving bacterial nanoformulations or nanoparticles synthesized using bacteria (BNPs) as the nanofactories. The B-NBPs were synthesized using high-pressure homogenization (HPH), jet milling, and hammer milling, giving rise to competent bacterial nanoformulations of size ranging from 250 to 500 nm. Following an overview of bacteria-based nanobiopesticides (B-NBPs) employed to prevent/treat plant diseases, the article highlights the role of BBCA’s role in plant protection as well as its antagonistic mechanisms. Further, the concept of B-NBPs, concentrating on Bacillus thuringensis-driven forms, is reviewed. The review then briefly explains the significance of BNPs in plant infection management. Finally, the concerns related to the efficacy of B-NBPs along with the prospects are also described.
