“…The textural features of nanoporous materials, including high surface area, large pore volume, tunable pore size, and stability in different environments, confer a more efficient loading of pesticides [ 68 ]. Moreover, it can target the delivery of pesticides to achieve increased disease control efficiencies over longer durations and to prevent degradation of the encapsulated molecules under adverse environmental conditions [ 69 , 70 ]. If nanoparticles could be used to deliver and protect dsRNAs, it will effectively improve dsRNA application prospects in the field.…”

Rhizoctonia solani is one of the important pathogenic fungi causing several serious crop diseases, such as maize and rice sheath blight. Current methods used to control the disease mainly depend on spraying fungicides because there is no immunity or high resistance available in crops. Spraying double-strand RNA (dsRNA) for induced-gene silencing (SIGS) is a new potentially sustainable and environmentally friendly tool to control plant diseases. Here, we found that fluorescein-labelled EGFP-dsRNA could be absorbed by R. solani in co-incubation. Furthermore, three dsRNAs, each targeting one of pathogenicity-related genes, RsPG1, RsCATA, and RsCRZ1, significantly downregulated the transcript levels of the target genes after co-incubation, leading to a significant reduction in the pathogenicity of the fungus. Only the spray of RsCRZ1 dsRNA, but not RsPG1 or RsCATA dsRNA, affected fungal sclerotium formation. dsRNA stability on leaf surfaces and its efficiency in entering leaf cells were significantly improved when dsRNAs were loaded on layered double hydroxide (LDH) nanosheets. Notably, the RsCRZ1-dsRNA-LDH approach showed stronger and more lasting effects than using RsCRZ1-dsRNA alone in controlling pathogen development. Together, this study provides a new potential method to control crop diseases caused by R. solani.

The significance of nanoparticles (NPs) in technological advancements is due to their adaptable characteristics and enhanced performance over their parent material. They are frequently synthesized by reducing metal ions into uncharged nanoparticles using hazardous reducing agents. However, there have been several initiatives in recent years to create green technology that uses natural resources instead of dangerous chemicals to produce nanoparticles. In green synthesis, biological methods are used for the synthesis of NPs because biological methods are eco-friendly, clean, safe, cost-effective, uncomplicated, and highly productive. Numerous biological organisms, such as bacteria, actinomycetes, fungi, algae, yeast, and plants, are used for the green synthesis of NPs. Additionally, this paper will discuss nanoparticles, including their types, traits, synthesis methods, applications, and prospects.

“…185 Nanotechnology is attracting substantial attention in agricultural pest control with the aim to formulate the active ingredients of chemical pesticides with nanoparticles, to generate 'nano-pesticides' that increase targeted delivery efficiency, stability and persistence as well as control the release of active ingredients in the environment. 186,187 It has been claimed that nano-pesticides could improve the efficiency of conventional pesticides by around 20%-30%, and achieve considerable pesticide efficacy at relatively low dosages. 185 It should be noted, however, that some nanoparticles (e.g., polymeric and lipid nanoparticles) have non-negligible toxicity to the environment and organisms, 188 making the development of nanoparticles with increased safety features necessary.…”

Virus‐like particles (VLPs) represent a biodegradable, biocompatible nanomaterial made from viral coat proteins that can improve the delivery of antigens, drugs, nucleic acids, and other substances, with most applications in human and veterinary medicine. Regarding agricultural viruses, many insect and plant virus coat proteins have been shown to assemble into VLPs accurately. In addition, some plant virus‐based VLPs have been used in medical studies. However, to our knowledge, the potential application of plant/insect virus‐based VLPs in agriculture remains largely underexplored. This review focuses on why and how to engineer coat proteins of plant/insect viruses as functionalized VLPs, and how to exploit VLPs in agricultural pest control. The first part of the review describes four different engineering strategies for loading cargo at the inner or the outer surface of VLPs depending on the type of cargo and purpose. Second, the literature on plant and insect viruses the coat proteins of which have been confirmed to self‐assemble into VLPs is reviewed. These VLPs are good candidates for developing VLP‐based agricultural pest control strategies. Lastly, the concepts of plant/insect virus‐based VLPs for delivering insecticidal and antiviral components (e.g., double‐stranded RNA, peptides, and chemicals) are discussed, which provides future prospects of VLP application in agricultural pest control. In addition, some concerns are raised about VLP production on a large scale and the short‐term resistance of hosts to VLP uptake. Overall, this review is expected to stimulate interest and research exploring plant/insect virus‐based VLP applications in agricultural pest management. © 2023 Society of Chemical Industry.
