“…Development of nanoparticle-based herbicides has also included a wider variety of nanoparticles. For example, montmorillonite clay layers coated with a pH dependent polymer [97], core-hollow shell manganese carbonate [98], nanosized tubular halloysite and platy kaolinite [99], amino-activated iron (II,III) oxide magnetic nanoparticles [100] and nanosized rice husks [101], have been used to date. Atrazine (C) Poly (lactic-co-glycolic Acid) Potato plant - [113] In this table, the tested herbicide with the HRAC MoA group and nanocarrier are listed.…”

Each year, 20%–40% of crops are lost due to plant pests and pathogens. Existing plant disease management relies predominantly on toxic pesticides that are potentially harmful to humans and the environment. Nanotechnology can offer advantages to pesticides, like reducing toxicity, improving the shelf-life, and increasing the solubility of poorly water-soluble pesticides, all of which could have positive environmental impacts. This review explores the two directions in which nanoparticles can be utilized for plant disease management: either as nanoparticles alone, acting as protectants; or as nanocarriers for insecticides, fungicides, herbicides, and RNA-interference molecules. Despite the several potential advantages associated with the use of nanoparticles, not many nanoparticle-based products have been commercialized for agricultural application. The scarcity of commercial applications could be explained by several factors, such as an insufficient number of field trials and underutilization of pest–crop host systems. In other industries, nanotechnology has progressed rapidly, and the only way to keep up with this advancement for agricultural applications is by understanding the fundamental questions of the research and addressing the scientific gaps to provide a rational and facilitate the development of commercial nanoproducts.

A dual drug-loaded HNT-CD glycocluster delivery system based on halloysite nanotubes and carbohydrate functionalized cyclodextrin was developed by a green protocol using solvent-free microwave irradiation.The nanohybrid was employed for concurrent load and release of silibinin and curcumin. The new delivery system was characterized by means of TGA, FT-IR spectroscopy, SEM and DLS. These techniques confirm the successful loading of the two drugs in the system. SEM and DLS measurements highlighted that the nanomaterial preserves a tubular structure with an average hydrodynamic radius of ca. 200 nm. The release of the drugs from the HNT glycocluster was investigated by means of UV-vis spectroscopy at two different pH values simulanting the typical physiological conditions of either gastric or intestinal fluids.Enzyme-linked lectin assays (ELLA) demonstrated that highly mannoside-cyclodextrins HNT entities display high affinity towards mannose selective ConA lectin. Biological assays showed that the new drug delivery system exhibits anti-proliferative activity against the investigated cell lines. Fluorescence microscopy confirmed ELLA results and it showed a high propensity of this drug delivery system to cross cell membranes and to penetrate into the cell nucleus. The results revealed that the synthesized multicavity system is a material of suitable size and nanoarchitecture to transport drugs into living cells.

“…This method is followed by various types of processes such as mechanical milling (Liversidge and Cundy, 1995;Merisko-Liversidge et al, 2003;Yadav et al, 2012), nanolithography, laser ablation (Hulteen et al, 1999;Amendola and Meneghetti, 2009) sputtering and thermal decomposition (Chrissafis and Bikiaris, 2011;Verma et al, 2018;Araújo et al, 2018) which have been described in Figure 2. While in bottom-up synthesis (physicochemical processes) NPs such as polymersomes (Kapakoglou et al, 2008;Christian et al, 2009), micelles (Zhu et al, 2011), liposomes and vesicles (Camelo et al, 2009) polymer conjugates (Grover and Maynard, 2010), capsules (Delcea et al, 2010;Moraes et al, 2011;Zhao et al, 2011), polymeric NPs (Grabnar and Kristl, 2011) and dendrimers (Ravoo, 2008) are synthesized by several processes like sol-gel method, green synthesis, spinning, and chemical vapour deposition (CVD) pyrolysis (Mann et al, 1997;Yarema et al, 2010;Iravani, 2011;Biswas et al, 2012;Ramesh et al, 2013;Mogilevsky et al, 2014;Liu D. et al, 2015;Needham et al, 2016;Parveen and Tremiliosi-Filho, 2016).

Nanotechnology has become a very advanced and popular form of technology with huge potentials. Nanotechnology has been very well explored in the fields of electronics, automobiles, construction, medicine, and cosmetics, but the exploration of nanotecnology’s use in agriculture is still limited. Due to climate change, each year around 40% of crops face abiotic and biotic stress; with the global demand for food increasing, nanotechnology is seen as the best method to mitigate challenges in disease management in crops by reducing the use of chemical inputs such as herbicides, pesticides, and fungicides. The use of these toxic chemicals is potentially harmful to humans and the environment. Therefore, using NPs as fungicides/ bactericides or as nanofertilizers, due to their small size and high surface area with high reactivity, reduces the problems in plant disease management. There are several methods that have been used to synthesize NPs, such as physical and chemical methods. Specially, we need ecofriendly and nontoxic methods for the synthesis of NPs. Some biological organisms like plants, algae, yeast, bacteria, actinomycetes, and fungi have emerged as superlative candidates for the biological synthesis of NPs (also considered as green synthesis). Among these biological methods, endophytic microorganisms have been widely used to synthesize NPs with low metallic ions, which opens a new possibility on the edge of biological nanotechnology. In this review, we will have discussed the different methods of synthesis of NPs, such as top-down, bottom-up, and green synthesis (specially including endophytic microorganisms) methods, their mechanisms, different forms of NPs, such as magnesium oxide nanoparticles (MgO-NPs), copper nanoparticles (Cu-NPs), chitosan nanoparticles (CS-NPs), β-d-glucan nanoparticles (GNPs), and engineered nanoparticles (quantum dots, metalloids, nonmetals, carbon nanomaterials, dendrimers, and liposomes), and their molecular approaches in various aspects. At the molecular level, nanoparticles, such as mesoporous silica nanoparticles (MSN) and RNA-interference molecules, can also be used as molecular tools to carry genetic material during genetic engineering of plants. In plant disease management, NPs can be used as biosensors to diagnose the disease.
