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.

“…Similar results of lower toxicity from PSNdelivered pesticide on earthworms were also found on several other studies. 82,83 Further, several studies reported reduced phytotoxicity of PSN-delivered pesticides in terms of chromosome aberration (CA) and mitotic index (MI), where a lower CA and higher MI indicate safer molecules. The Vicia faba chromosomal aberration indexes of lambda cyhalothrin EC were 0.21, 0.25, and 0.31 at concentrations of 10, 50, and 100 mg/L, whereas those of dopamine-conjugated MSN-encapsulated lambda cyhalothrin were 0.04, 0.05, and 0.06, respectively, at the same concentration.…”

In precision agriculture, nanotechnology has made significant contributions to the development of a smart cropping system through the support of unique properties of nanomaterials. Of the various nanomaterials, porous nanomaterials have an outstanding performance in building a sustainable delivery system for agrochemicals. In pesticide delivery, amorphous porous silica nanomaterials are considered as some of the most suitable options because of their easy synthesis processes, nontoxic nature, structural variation, tunable porous structure, physical and chemical stability, and ease of surface functionality. So far, multiple roles of these materials have been discussed in the literature; however, the influence of porous structure and structural variations toward developing a sustainable delivery system was not clear. A comprehensive review of the compatibility among the porous silica nanocarriers and pesticide molecules is also lacking. Thus, this review discusses the progress of porous amorphous silica nanomaterial synthesis, their structural variation, and surface modification for effective delivery of different pesticides to explore their potential as carriers.

BackgroundPesticide formulations based on nanotechnology can effectively improve the efficiency of pesticide utilization and reduce pesticide residues in the environment. In this study, mesoporous silica nanoparticles containing disulfide bonds were synthesized by the sol‐gel method, carboxylated and adsorbed with lufenuron, and grafted with cellulose to obtain a lufenuron‐loaded nano‐controlled release formulation (Luf@MSNs‐ss‐cellulose).ResultsThe structure and properties of Luf@MSNs‐ss‐cellulose were characterized. The results showed that Luf@MSNs‐ss‐cellulose exhibits a regular spherical shape with 12.41% pesticide loading. The highest cumulative release rate (73.46%) of this pesticide‐loaded nanoparticle was observed at 7 d in the environment of glutathione and cellulase, which shows redox‐enzyme dual‐responsive performance. As a result of cellulose grafting, Luf@MSNs‐ss‐cellulose had a small contact angle and high adhesion work on corn leaves, indicating good wetting and adhesion properties. After 14 d of spraying with 20 mg L‐1 formulations in the long‐term control efficacy experiment, the mortality of Luf@MSNs‐ss‐cellulose against Ostrinia furnacalis larvae (56.67%) was significantly higher than that of commercial Luf@EW (36.67%). Luf@MSNs‐ss‐cellulose is safer for earthworms and L02 cells.ConclusionThe nano‐controlled release formulation obtained in this study achieved intelligent pesticide delivery in time and space under the environmental stimulation of glutathione and cellulase, providing an effective method for the development of novel pesticide delivery systems.This article is protected by copyright.
