Abstract

Efforts to achieve sustainable agriculture have accelerated the search for environmentally friendly alternatives to conventional agrochemicals. Ocimum sanctum (holy basil, tulsi), a traditional medicine endowed with diverse biologically active constituents, can be used to synthesize phytogenic nanoparticles (NPs) that may boost biocontrol in industrial crop systems. This review covers the botany and phytochemistry of O. sanctum pertaining to the biosynthesis of NPs, green synthesis procedures, characterization using various physicochemical techniques, and other elements that affect their properties. The effectiveness of O. sanctum-derived NPs against important bacterial as well as fungal phytopathogens is evaluated, particularly in terms of the action of membrane disruption, generation of reactive oxygen species (ROS), and other means. Its application as seed treatment, foliar spray, soil amendment, or in synergism with biopesticides and biofertilizers for major industrial crops is presented. Additionally, the toxicological and environmental aspects, such as phytotoxicity, soil microbiology, and human exposure and risk, are evaluated regarding the sustainable application of these nanomaterials. Finally, the challenges related to the unavailability of established criteria for standardization and scale-up of work, policy, and multidisciplinary approaches, with molecular technologies, are discussed along with the identified gaps in the literature for future research. Overall, the review highlights the potential of O. sanctum-derived phytogenic NPs (PNPs) as novel and eco-friendly biocontrol agents, recommending their use in modern agricultural practices to improve crop productivity and ensure ecological safety.
植物源性纳米颗粒,源自于加强工业作物系统生物防治的圣草
实现可持续农业的努力加速了寻找对环境友好的传统农用化学品替代品的工作。圣罗勒(Ocimum sanctum)是一种具有多种生物活性成分的传统药物,可用于合成植物源性纳米颗粒(NPs),这种纳米颗粒可能促进工业作物系统的生物防治。本文综述了植物植物学和植物化学方面的研究进展,包括植物NPs的生物合成、绿色合成方法、各种物理化学技术的表征以及影响其性质的其他因素。我们评估了O. sanctum衍生的NPs对重要细菌和真菌植物病原体的有效性,特别是在膜破坏作用、活性氧(ROS)的产生和其他手段方面。介绍了其在主要工业作物上作为种子处理、叶面喷施、土壤改良剂或与生物农药和生物肥料协同使用的应用。此外,对这些纳米材料的可持续应用进行了毒理学和环境方面的评估,如植物毒性、土壤微生物学和人类暴露和风险。最后,讨论了与标准化和扩大工作、政策和多学科方法以及分子技术相关的既定标准的不可获得性相关的挑战,以及文献中确定的未来研究空白。总体而言,本综述强调了植物源NPs (PNPs)作为新型生态友好型生物防治剂的潜力,建议将其应用于现代农业实践,以提高作物生产力和确保生态安全。

期刊介绍: Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
