“…These types of NBPs can be either living or nonliving and can be used to control a variety of pests, including insects, nematodes, and plant pathogens. 92 One example of a living B-NBP is Bacillus thuringiensis (Bt), which is used to control a wide range of lepidopteran pests, including moths and butterflies. 93 The average particle size of nanosized Bt was observed to be between 250 and 500 nm, with a minor fraction of particles falling below 1 μm.…”

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.

“…Several studies on the interaction between nanomaterials and plant-benefitting bacteria, called Plant Growth-Promoting Rhizobacteria (PGPR), have been identified as a novel approach in sustainable agriculture [ 78 ]. Through the application of both PGPR and nanomaterials, plants may be able to resist environmental stress through several physiological and morphological mechanisms, such as improved root system nutrient uptake and induced expression of cellular antioxidative enzymes [ 79 ]. By using silicon nanoparticles as a seed priming agent, Mahakham et al studied the role of silicon nanoparticles in the cell growth process.…”

The global community decided in 2015 to improve people’s lives by 2030 by setting 17 global goals for sustainable development. The second goal of this community was to end hunger. Plant seeds are an essential input in agriculture; however, during their developmental stages, seeds can be negatively affected by environmental stresses, which can adversely affect seed vigor, seedling establishment, and crop production. Seeds resistant to high salinity, droughts and climate change can result in higher crop yield. The major findings suggested in this review refer nanopriming as an emerging seed technology towards sustainable food amid growing demand with the increasing world population. This novel growing technology could influence the crop yield and ensure the quality and safety of seeds, in a sustainable way. When nanoprimed seeds are germinated, they undergo a series of synergistic events as a result of enhanced metabolism: modulating biochemical signaling pathways, trigger hormone secretion, reduce reactive oxygen species leading to improved disease resistance. In addition to providing an overview of the challenges and limitations of seed nanopriming technology, this review also describes some of the emerging nano-seed priming methods for sustainable agriculture, and other technological developments using cold plasma technology and machine learning.

Background Recent concerns linked with the application of chemical pesticides and the increasing necessity of low inputs sustainable agriculture have put the use of microbial biocontrol agents and bio-pesticides to the forefront for their application against plant pathogens and insect–pest management. Results This review tended to scrutinize the prospects of microbial biocontrol agents and microbes-based nano-formulations against plant diseases and for pest management with emphasis on bacteria-based nanoparticles, especially derived from Bacillus species. It also tended to discuss the probable mechanism of action and effect on plant growth along with its prospects in a brief manner. Conclusion The use of microbial biocontrol agents offers effective, eco-friendly, and long-lasting management of plant diseases. The employment of nanotechnology in the field of biopesticides has emerged as a promising solution. Nano-biopesticides in the form of biologically derived active pesticides or compounds integrated as nanoparticles and integrated into a suitable polymer have application in insect–pest management.
