“…Furthermore, SLNs can also provide controlled release of various lipophilic components, due to decreased mobility of the active in the solid matrix [28,29]. Surfactants are used to stabilize the SLN when dispersed into water [5]. Their main drawbacks are that they have a low loading efficiency, and the active may leak out of the structure during storage [30].…”

“…Nanotechnology has led to the development of new concepts and agricultural products with immense potential to manage the aforementioned problems. Nanotechnology has substantially advanced in medicine and pharmacology, but has received comparatively less interest for agricultural applications [4,5]. The use of nanotechnology in agriculture is currently being explored in plant hormone delivery, seed germination, water management, transfer of target genes, nanobarcoding, nanosensors, and controlled release of agrichemicals [6].…”

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.

“…Nanogels, also known as hydrogel nanoparticles, are water-swollen nanosized polymeric networks. They consist of either physically or chemically cross-linked polymer chains (hydrophilic or amphiphilic) that can swell but do not dissolve in water [ 63 ]. The properties of nanogels can be controlled via the functional monomers, the degree of crosslinking (produced by different methods, such as ionic crosslinking, self-assembly, crystallization, crosslinking polymerization, radiation crosslinking, or functional group crosslinking), and the preparation method, to enhance responsiveness to the surrounding environment [ 64 , 65 ].…”

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.

“…the applications of nanotechnology in agriculture sector, it thought that nanotechnology will totally revolutionize it (Singh and Prasad 2016). This nanotechnology has the ability to penetrate different agricultural fields including treatment and detection of plant diseases (Park et al 2006;Al-Samarrai 2012;Servin et al 2015;Álvarez et al 2016;Mignani et al 2017;Ray et al 2017), using as sensors (Fryxell and Cao 2007;Otles and Yalcin 2010;Farrell et al 2013;Ansari et al 2016;Chhipa and Joshi 2016;Dubey and Mailapalli 2016;Jyoti and Tomar 2016;Purkayastha and Manhar 2016;Bäcker et al 2017;Bazin et al 2017;Ray et al 2017;Saylan et al 2017),( Only recent references are sufficient) nanofertilizers (Naderi and Danesh-Shahraki 2013;Tarafdar et al 2014;Dubey and Mailapalli 2016;Chhipa 2016;Chhipa and Joshi 2016), nanopesticides (Kah et al 2013Dubey and Mailapalli 2016;Chhipa 2016;Chhipa and Joshi 2016;Pandey et al 2016;Balaure et al 2017;Jacques et al 2017), and using in gene transfer as smart delivery systems (Peters et al 2016;Singh and Prasad 2016). The over application of nanomaterials in agriculture leads to the negative effects representing in the toxic action of these nanomaterials for the agroecosystems (Holden et al 2013;Hong et al 2013;García-Gómez et al 2015;Belal and El-Ramady 20...…”

T HE GLOBAL agricultural production suffers from many problems and challenges including climate change, natural resources depletion, environmental pollution, soil degradation, etc. Hence, the global security of this vital sector definitely will be threaten including water security, soil security, energy security, food security, etc. Day by day, several attempts already have been conducted in seeking of the humanity for suitable and sustainable solutions to overcome these previous problems. Nanotechnology was and still one of the most important solutions, which will help us to overcome these problems. So, several nanomaterials have been successfully used in many agro-production fields including nanofertilizers, nanopesticides, nanoremediation, nanobiosensors as well as using of nanoparticles in agri-food production. These nanomaterials can help the agro-production to exploit the natural resources in more sustainable manner and to minimize the agro-wastes. Therefore, regulations for more safety in nanomaterials utilization for agro-production should be starting from the handling for seed germination till the handling for postharvest of agricultural products. Several investigations have been proved the importance of nanomaterials in global securities, the agro-production through the nano-agro-chemicals, management of the agro-wastes, etc. Therefore, this review will highlight new insights and novel approaches for using nanomaterials for sustainable agro-productivity. It will also include the impact of nanomaterials on the agro-environement and the enhanced productivity in frame of sustainability.
