“…The plant's mechanism of nanoparticle adsorption and absorption to enhance the efficacy of the entrapped agrochemicals is a popular topic of interest (Avellan et al 2021;Grillo et al 2021a). Previous studies have shown that these mechanisms are influenced by the particle's size (Cui et al 2008), charge (Hu et al 2020), and hydrophobicity (Sharma et al 2020;Zhang et al 2021). Research focusing on the foliar applications of pesticide entrapped nanoparticles is often conducted as these plant tissues are frequently exposed to pests and environmental conditions.…”

Zein nanoparticles (ZNPs) were synthesized with a cationic surfactant, didodecyldimethylammonium bromide (122.9 ± 0.8 nm, + 59.7 ± 4.4 mV) and a non-ionic surfactant, Tween 80 (118.7 ± 1.7 nm, + 26.4 ± 1.1 mV). Lignin-graft-poly(lactic-co-glycolic) acid nanoparticles (LNPs) were made without surfactants (52.9 ± 0.2 nm, − 54.9 ± 0.5 mV). Both samples were applied as antifungal seed treatments on soybeans, and their impact on germination and plant health was assessed. Treated seeds showed high germination rates (> 90% for all treatment groups), similar to the control group (100%). Root and stem lengths and the dry biomass of treated seeds were not statistically distinguishable from the control. Foliage from seed-treated plants was fed to larvae of Chrysodeixis includens with no differences in mortality between treatments. No translocation of fluorescently tagged particles was observed with fluorescence microscopy following seed treatment and germination. Nano-delivered azoxystrobin provided ~ 100% protection when LNPs were used. Results suggest ZNPs and LNPs are safe and effective delivery systems of active compounds for seed treatments.

“…Moreover, the absence of individual rGO sheets or Cu 2– x Se NCs confirms the successful synthesis of rGO-Cu 2– x Se composite. The HR-TEM performed on Cu 2– x Se NCs and rGO-Cu 2– x Se shows lattice fringes having a d -spacing value of 0.33 nm, which corresponds to the (111) plane of Cu 2– x Se NCs (inset in Figure C,D). − Here, the average particle size found to be decrease from 15 to 9 nm as compared to our previous work, after changing the copper to selenourea ratio. This size reduction is important for the diseases control here as inverse proportion of the Cu particles size with the antimicrobial property has been observed before, and here it is expected to contribute for the combination antifungal efficiency with captan.…”

Pesticide leaching and soil contamination are major issues in the present agriculture formulations. Hence, here 2D graphene oxide in combination with cationic, anionic, or nonionic polymers were tested for runoff resistance and targeted release behavior. Cationic polymer supplemented the binding of rGO on leaf surface by 30% more than control and reduced off-target leaching in soil by 45% more than control. Further, to enhance the fruit rot control caused by Colletotrichum capsici in chili crop, the rGO was decorated with Cu2–x Se nanocrystals, which provided combined disease control with captan. The chitosan coating in the nanocomposite added targeted pH-responsive fungal inhibition behavior and could reduce the C. capsici growth by ∼1/2 times compared to captan control.

“…While hydrophilic NPs should not be able to directly cross the cuticle, recent work has described a higher root uptake of NP presenting a hydrophobic surface (Sharma et al, 2020). This suggests that the cuticle layers might not be as impenetrable as what was previously hypothesized in the literature and that uptake depends on the NP coating, corona formation, and resulting surface properties.…”

The development of nanotechnologies for more sustainable agriculture is an innovative strategy proposed to increase food production while decreasing material inputs and reducing environmental impacts. Nanoparticles (NPs) applied to seeds, soil, or leaves interact with plants at two major interfaces: the rhizoplane (root-rhizosphere interface) or the phylloplane (atmosphereleaf interface). NP transformations occurring at these interfaces control their bioavailability, while plant structures are barriers to NP absorption and bottlenecks for their translocation. This chapter focuses on the complex interplays driving NP uptake, translocation, and accumulation into plant tissues. Foliar treatments appear to present advantages over soil application for the delivery of NPs to certain compartments. The adjustment of the size and surface properties of nanoparticles could allow specific targeting (e.g., apoplast, symplast, organelles) and designed mobility to freely reach the phloem or accumulate in the mesophyll. Furthermore, this chapter highlights the knowledge gaps that need to be overcome for the safe and efficient development of nano-enabled agriculture. The parameters influencing for NP movement across cuticle barriers, cell walls, and cell membranes are still to be identified. Consequently, NP mobility in the root cortex and through the endodermis before entering the xylem or in the mesophyll before loading the phloem is not predictable yet. The processes that drive NP movement from the mesophyll cells to the sinks and their capacity to load the phloem are also poorly characterized. In addition, plant physiological responses and in vivo transformations, such as dissolution rates, or protein corona formation around NPs, remain important knowledge gaps that need to be addressed to understand, predict, and regulate NP translocation in plants and their bioavailability, thus enabling safe and efficient, targeted delivery of NPs for agricultural purposes.
