“…Nanotechnology has a wide range of potential applications, which will revolutionize the fields of science and technology in the 21st century, including in the sectors of materials science, biomedicine, agriculture, and industry, and will play important roles in various changing fields [ 4 ]. The application of nanotechnology to plant science and agriculture is one of the fastest-growing areas of nanoresearch [ 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. In agriculture, nanoparticles are mainly used to effectively deliver exogenous insecticidal factors to improve plant health, expand the insecticidal spectrum, reduce pesticide use, prolong the period of efficacy, and reduce environmental pollution.…”

The unscientific application of pesticides can easily cause a series of ecological environmental safety issues, which seriously restrict the sustainable development of modern agriculture. The great progress in nanotechnology has allowed the continuous development of plant protection strategies. The nanonization and delivery of pesticides offer many advantages, including their greater absorption and conduction by plants, improved efficacy, reduced dosage, delayed resistance, reduced residues, and protection from natural enemies and beneficial insects. In this review, we focus on the recent advances in multifunctional nanoparticles and nanopesticides. The definition of nanopesticides, the types of nanoparticles used in agriculture and their specific synergistic mechanisms are introduced, their safety is evaluated, and their future application prospects, about which the public is concerned, are examined.

“…Nanotechnology allows to achieve a diverse range of objectives, including but not limited to higher solubility of active ingredients (AIs), slower release, improved delivery efficiency, and better bioactivity. These versatile characteristics make them well-suited for a wide range of applications. − In recent years, there has been a growing interest among scientists in utilizing nanoparticles for the development of environmentally friendly pesticides, and the construction of nanosized pesticides and plant elicitors is developing fast in recent years. − These novel nanopesticides can achieve several advantages, such as better stability, controlled/smart release, targeted delivery, and higher control efficacy. − Wang et al found that the overall efficacy of nanopesticides against target pests was increased by 31.5%, with an 18.9% increased efficacy in field trials when compared with non-nanoscale pesticides. Importantly, the higher utilization rate of nanopesticides is beneficial for reducing the application of AIs, alleviating the negative effects on environment and human health. − Consequently, exploring efficient nanocarriers for the effective utilization of pesticides in agricultural production is a key aspect of plant protection research.…”

There is a growing demand for applying green pesticides instead of traditional synthetic pesticides to minimize potential threats to food and environmental safety. Insect growth regulators (IGRs) are regarded as a secure alternative, but their control efficacy needs to be improved to meet actual demands. Herein, a star polymer (SPc) was constructed and applied as an efficient pesticide nanocarrier, which could be spontaneously conjugated with IGR methoxyfenozide via hydrogen bonding with a high pesticide loading content of 32.66%. The combination of the methoxyfenozide/SPc complex at a mass ratio of 1:1 could break the self-aggregated methoxyfenozide, reducing its particle size from 1084 to 27 nm, and the methoxyfenozide/SPc complex consisted of smooth spherical nanoparticles with uniform distribution. Importantly, with the aid of SPc, the mortality of methoxyfenozide-treated Spodoptera litura larvae was significantly increased by 1.2 times at 1 day and 2.2 times at 7 days after the oral feeding. Meanwhile, the weight and length of the survival larvae fed with the methoxyfenozide/SPc complex were less than those with methoxyfenozide alone. Transcriptome results revealed that the oral feeding of the methoxyfenozide/SPc complex could further disturb the expression of various key genes related to insect hormone synthesis and metabolism, hormone receptor, and cuticle biosynthesis. In larvae exposed to the methoxyfenozide/SPc complex, we observed the downregulation of key genes involved in hormone synthesis and metabolism, including cytochrome P450 18a, farnesol dehydrogenase, and juvenile hormone acid O-methyltransferase. This disruption in hormone regulation resulted in impaired insect molting. Simultaneously, the expression of genes associated with cuticle formation, such as chitin synthase 2, obstructor-E, and larval cuticle protein, was also suppressed. The current study provides an efficient nano-delivery system for IGRs to improve stomach toxicity against insect pests, which shows great potential in green pest management.

“…It can be an efficient and eco-friendly alternative to agrochemicals that promote regenerative agriculture, integrated with the approach associated with One Health. Bionanotechnology could be applied in agriculture, remediation, water treatment, pest detection, and control, for example, developing porous nano zeolites capable of absorbing water or soil chemical contaminants [ 11 ]; nanocapsules capable of releasing the necessary pesticide concentration on demand [ 12 ] nanomembranes that control the release of water, fertilizers, and herbicides and serve as water purifiers [ 13 , 14 ]; nanosensors capable of monitoring soil and plants and detecting contaminants and pests [ 15 , 16 ]; magnetic nanoparticles as an agent to combat soil contaminants [ 17 ]; among other applications.…”

Healthy eating habits are one of the requirements for the health of society. In particular, in natura foods are increasingly encouraged, since they have a high concentration of nutrients. However, these foods are often grown in the presence of agrochemicals, such as fertilizers and pesticides. To increase crop productivity and achieve high vigor standards in less time, farmers make excessive use of agrochemicals that generate various economic, environmental, and clinical problems. In this way, bionanotechnology appears as an ally in developing technologies to improve planting conditions, ranging from the health of farmers and consumers to the production of new foods and functional foods. All these improvements are based on the better use of land use in synergy with the lowest generation of environmental impacts and the health of living beings, with a view to the study and production of technologies that take into account the concept of One Health in its processes and products. In this review article, we will address how caring for agriculture can directly influence the quality of the most desired foods in contemporary society, and how new alternatives based on nanotechnology can point to efficient and safe solutions for living beings on our planet.
