“…[130] The nano-based formulation can significantly address the agricultural challenges; however, their toxic effects on nature shouldn't be neglected. [131,132] It is expected that green nanopesticides will bring a revolution in agriculture for sustainable development as effective agrochemicals. [133] The key characteristics of nanopesticides are their nano-size which exploits properties that the same substance's macro-size can't and thus provide effective results.…”

The survival of humans depends critically on crop production, making crop protection absolutely essential. Numerous studies have suggested that nanopesticides could soon fully replace conventional pesticides since they are far more effective than those now in use. Due to an increase in their surface‐to‐volume ratio, nanomaterials exhibit different properties from their bulk counterparts. Nanopesticides are pesticides that have been made with these nanoparticles and have a high application efficiency and significantly fewer hazardous environmental impacts than pesticides that have been made chemically. Various formulation strategies, which include the containment of the active substance by the nanoparticles, have previously been established, exhibiting promising effects on the pests. Target specificity, high stability, and controlled active ingredients (AIs) release are a few of the noteworthy qualities these nanopesticides offer. The development of green nanopesticides derived from nature, which have very low ecotoxicities and nanoscale qualities, can also have a significant positive impact on crop output. However, before being mass‐produced and used, the discovery still has to be thoroughly examined to determine its effects on people and the environment due to the lack of conclusive proof demonstrating its toxicity. This paper aims to represent the use of nanopesticides in crop protection and a detailed overview of the various methods for the formulation of nanopesticides. Also, the possible negative impacts on the non‐target species by the application of nanopesticides have been briefly discussed. The need for the development of green nanopesticides to avoid the negative aspects of nanopesticides has also been highlighted.

“…Thus, due to the reduced dose requirement, the cost of application is also reduced. Also, it is important for the controlled release formulations that they must remain inactive until the active ingredient is released (Shekhar et al, 2021).…”

Globally, between one quarter and one-third of total grains produced each year are lost during storage mainly through infestation of insect pests. Among the available control options such as chemical and physical techniques, fumigation with aluminum phosphide (AlP) is so far considered the best control strategy against storage insect pests. However, these insect pests are now developing resistance against AIP due to its indiscriminate use due to non-availability of any effective alternative control option. Resistance to AIP among storage insect pests is increasing, and its inhalation has shown adverse effects on animals and human beings. Nanotechnology has opened up a wide range of opportunities in various fields such as agriculture (pesticides, fertilizers, etc.), pharmaceuticals, and electronics. One of the applications of nanotechnology is the usage of nanomaterial-based insecticide formulations for mitigating field and storage insect pests. Several formulations, namely, nanoemulsions, nanosuspensions, controlled release formulations, and solid-based nanopesticides, have been developed with different modes of action and application. The major advantage is their small size which helps in proper spreading on the pest surface, and thus, better action than conventional pesticides is achieved. Besides their minute size, these have no or reduced harmful effects on non-target species. Nanopesticides can therefore provide green and efficient alternatives for the management of insect pests of field and storage. However, an outcry against the utilization of nano-based pesticides is also revealed. It is considered by some that nano-insecticides may also have hazardous effects on humans as well as on the environment. Due to limited available data, nanopesticides have become a double-edged weapon. Therefore, nanomaterials need to be evaluated extensively for their large-scale adoption. In this article, we reviewed the nanoformulations that are developed and have proved effective against the insect pests under postharvest storage of grains.

“…The structure of NPs can involve nanosized active substances coated with polymers, nanosized active substances stabilized with polymers on the surface, polymeric carriers mixed with lipids with trapped active substances, vectorized polymeric carriers [ 47 ], and other forms of support such as nanofibers and nanogels. Traditionally, nanoparticles can be distinguished in the nanosphere and nanocapsule classification.…”

Pesticides have been used in agricultural activity for decades because they represent the first defense against pathogens, harmful insects, and parasitic weeds. Conventional pesticides are commonly employed at high dosages to prevent their loss and degradation, guaranteeing effectiveness; however, this results in a large waste of resources and significant environmental pollution. In this regard, the search for biocompatible, biodegradable, and responsive materials has received greater attention in the last years to achieve the obtention of an efficient and green pesticide formulation. Nanotechnology is a useful tool to design and develop “nanopesticides” that limit pest degradation and ensure a controlled release using a lower concentration than the conventional methods. Besides different types of nanoparticles, polymeric nanocarriers represent the most promising group of nanomaterials to improve the agrochemicals’ sustainability due to polymers’ intrinsic properties. Polymeric nanoparticles are biocompatible, biodegradable, and suitable for chemical surface modification, making them attractive for pesticide delivery. This review summarizes the current use of synthetic and natural polymer-based nanopesticides, discussing their characteristics and their most common design shapes. Furthermore, we approached the instability phenomena in polymer-based nanopesticides and strategies to avoid it. Finally, we discussed the environmental risks and future challenges of polymeric nanopesticides to present a comprehensive analysis of this type of nanosystem.
