“…So that, nanoherbicides have been used for the combat of weeds. In the research of Abigail and Chidambaram () argue that nanomaterials or nanostructures materials‐based formulations could improve the efficacy of the herbicides, enhancing the solubility and reducing the toxicity in comparison with the conventional herbicides. Chi, Zhang, Xiang, Cai, and Wu () showed that controlled‐release herbicide particles with a nanocomposite consisting of attapulgite (ATP), NH 4 HCO 3 , amino silicone oil (ASO), poly (vinyl alcohol) (PVA), and glyphosate (Gly) are new technologies that could effectively decrease the loss of Gly and thus improve the control efficiency on weeds.…”

“…So that, nanoherbicides have been used for the combat of weeds. In the research of Abigail and Chidambaram (2017) 2018showed that atrazine-loaded poly (ε-caprolactone) (PCL) nanocapsules (at 2,000 g ha −1 ) decreased the root effectively and shoot growth in the post-emergence herbicidal activity of Amaranthus viridis L. (slender amaranth) and Bidens pilosa L. (hairy beggarticks). Despite the effectiveness of nanoherbicides, some barriers still hinder the useful application of nanomaterials in agriculture, such as the lack of specific regulatory frameworks for ecological risk assessments (Walker et al, 2017).…”

Nanoscience and nanotechnology have been shown to have the capacity to help study, manipulation,design, and synthesis of new nano-sized materials to manufacture new products with desirable features never seen before. The unique properties of materials at nanoscale opens an excellent possibility for nanotechnology to be used in soil environmental remediation, and water, and air decontamination. In crop management, nanomaterials are used to regulate the controlled release of nutrients, fertilizers, and pesticides. However, it is not only necessary to expose the positive effects by the application of the nanomaterials but also to demonstrate the impacts on soil and nontarget organisms (plants, mesofauna, macrofauna, and soil microbiota). In this context, pieces of evidence on the adverse effects of engineered nanoparticles (ENP) on the physicochemical and biological properties of soils are discussed in this paper. We have found a diversity of contradictory results. The summaries, findings, and conclusions of most of the investigations support the need to understand the biological or physicochemical transformation and transport of ENP in soil, and in the plant-organism relationship. Better understanding regarding the soil biota coupled with the ecological ENP behavior could ensure the safe use of ENP. Nanomaterials can change the physicochemical and biological properties of the soils; consequently, long-term in situ field trials are required, and meanwhile, land-application of nanomaterials should be limited to scientific experiments to fill knowledge gaps to not jeopardize the global food production or the environment and worldwide human health.

“…Considering the failure of translational use and alternative herbicides in weed control, PCL nanoparticles are set up for the sustainable use of bioactive compounds, including the triazine class (ametryn, atrazine, and simazine), polycaprolactone, and metribuzin (Table 2). In fact, PCL is very valuable for the encapsulation of herbicides, especially atrazine herbicides, due to their chemical composition, which is easily modulable; their biodegradable properties; their biocompatibility; their distribution control; the high colloidal stability of their molar masses; and the control of their architectures [100]. Currently, nanoprecipitation and emulsion-solvent diffusion methods are used for the production of PCL nanoherbicides, such as nano-PCL-atrazine and nano-PCL-metribuzin, which are discussed below.…”

The number of effective herbicides available to farmers is steadily decreasing due to increasing herbicide resistance. It seems very important to address and effectively deal with the main weed management challenges (low crop yield and environmental pollution) by investigating the potential of newly introduced materials, such as biocompatible polymer-based nanoparticles. The current review aims to encourage agricultural or environmental researchers to conduct new research on the synthesis and application of modified herbicides, such as nanoherbicides, for application in weed management and to provide a comprehensive foundation on the topic. Such nanosystems could help with the promotion of the controlled release of active ingredients and extend their action time, resulting in a reduction in dose and application number; improve the physical and chemical characteristics of the herbicide to increase foliar adhesion; prevent degradation that results from environmental factors (such as sunlight, temperature, microorganisms, or pH); and decrease herbicide leaching and contamination of the environment. Furthermore, it has been indicated that some polymeric nanocarriers can penetrate biological barriers, including membranes and plant cell walls, and translocate across vascular tissues, resulting in a more efficient delivery of active ingredients. Poly(epsilon-caprolactone) is a biocompatible material that is easily decomposable by enzymes and fungi. PCL nanoparticles could be applied as nanocarriers of herbicides in agriculture due to their low toxicity, their potential for large-scale synthesis from inexpensive materials, their ability to dissolve herbicides, their high loading capacity, and their ability to help minimize the chemical decomposition of herbicides.

“…The efficacy of herbicides can be increased via nanoherbicides that generally anticipate biodegradable polymeric components. For example, poly(-caprolactone) is widely used to contain atrazine owing to its better physiochemical properties and greater bioaccessibility and biocompatibility (Abigail and Chidambaram, 2017). Synthetic chemicals can be introduced in hosts using a conveyer system based on CNTs (Raliya et al, 2013) after targeting a decrease in the number of chemicals discharged into the environment that may damage other plant cells (Hajirostamlo et al, 2015).…”

Agriculture is an important source of human food. However, current agricultural practices need modernizing and strengthening to fulfill the increasing food requirements of the growing worldwide population. Genome editing (GE) technology has been used to produce plants with improved yields and nutritional value as well as with higher resilience to herbicides, insects, and diseases. Several GE tools have been developed recently, including clustered regularly interspaced short palindromic repeats (CRISPR) with nucleases, a customizable and successful method. The main steps of the GE process involve introducing transgenes or CRISPR into plants via specific gene delivery systems. However, GE tools have certain limitations, including time-consuming and complicated protocols, potential tissue damage, DNA incorporation in the host genome, and low transformation efficiency. To overcome these issues, nanotechnology has emerged as a groundbreaking and modern technique. Nanoparticle-mediated gene delivery is superior to conventional biomolecular approaches because it enhances the transformation efficiency for both temporal (transient) and permanent (stable) genetic modifications in various plant species. However, with the discoveries of various advanced technologies, certain challenges in developing a short-term breeding strategy in plants remain. Thus, in this review, nanobased delivery systems and plant genetic engineering challenges are discussed in detail. Moreover, we have suggested an effective method to hasten crop improvement programs by combining current technologies, such as speed breeding and CRISPR/Cas, with nanotechnology. The overall aim of this review is to provide a detailed overview of nanotechnology-based CRISPR techniques for plant transformation and suggest applications for possible crop enhancement.
