“…Nevertheless, better experimental design and standardized protocols are needed, because a large number of published studies lack adequate controls for comparison (e.g. with a commercial formulation or bulk materials), 23,63 making it difficult to assess the benefits of nano-enabled products. Furthermore, field testing is a critical step in ensuring the effectiveness of a nanoformulation.…”

Bioherbicides are composed of microorganisms or natural compounds and are used for weed control; however, they have specific weaknesses and constraints that hinder their development and success under field conditions. Nanotechnology can help to overcome these limitations by providing a good starting point for the design of specific formulations and carriers that minimize the deficiencies of natural compounds and microorganisms, such as low solubility, short shelf life or a loss of viability. In addition, nanoformulations can help to improve the efficacy of bioherbicides by increasing their effectiveness and bioavailability, reducing the amount required for a treatment, and enhancing their ability to target specific weeds while preserving the crop. However, it is important to choose the right materials and nanodevices depending on specific needs and considering several factors inherent to nanomaterials such as production cost, safety or possible toxic effects. © 2023 Society of Chemical Industry.

“…However, a study 80 evaluated the impact of GNMs at concentrations from 100 to 1000 mg kg −1 on earthworms, which is more representative of real application scenarios. A study 9 reported a median and mean dose of nanomaterial used in soil-based applications of 125 and 743 mg kg −1 for the timeline of 2009 to 2022, respectively. In a nematode based study, it was reported that a 130 day exposure to 10 g kg −1 of GNMs resulted in an increase of bacterivores and fungivores but a decrease in several nematode community parameters associated with diversity, species richness, and structure.…”

Thus, this low adsorbent (GNMs) to adsorbate (nutrient) ratio in the soil root zone, may limit the usefulness in employing GNMs for this purpose.…”

“…7,8 Several nanomaterials, such as metal, metal oxide, and carbon-based nanoparticles have been tested as agricultural treatments since 2009. 9 Due to their very high specific surface area, excellent adsorption capacity, low production cost, and ability to serve as nano delivery agents for agrochemicals, two-dimensional carbon nanomaterials such as graphene or graphene oxide (GO) have been gaining increasing interest as agricultural nano-additives. Graphene based nanomaterials (GNMs) are classified as "nanomaterial enhanced fertilizers" 10 and have been shown to enhance plant growth and development in the soil environment.…”

The application of foliar sprays of suspensions of relatively insoluble essential element salts is gradually becoming common, chiefly with the introduction of nano-technology approaches in agriculture. However, there is controversy about the effectiveness of such sparingly soluble nutrient sources as foliar fertilizers. In this work, we focussed on analysing the effect of adding Ca-carbonate (calcite, CaCO3) micro- and nano-particles as model sparingly soluble mineral compounds to foliar fertilizer formulations in terms of increasing the rate of foliar absorption. For these purposes, we carried out short-term foliar application experiments by treating leaves of species with variable surface features and wettability rates. The leaf absorption efficacy of foliar formulations containing a surfactant and model soluble nutrient sources, namely Ca-chloride (CaCl2), magnesium sulphate (MgSO4), potassium nitrate (KNO3), or zinc sulphate (ZnSO4), was evaluated alone or after addition of calcite particles. In general, the combination of the Ca-carbonate particles with an essential element salt had a synergistic effect and improved the absorption of Ca and the nutrient element provided. In light of the positive effects of using calcite particles as foliar formulation adjuvants, dolomite nano- and micro-particles were also tested as foliar formulation additives, and the results were also positive in terms of increasing foliar uptake. The observed nutrient element foliar absorption efficacy can be partially explained by geochemical modelling, which enabled us to predict how these formulations will perform at least in chemical terms. Our results show the major potential of adding mineral particles as foliar formulation additives, but the associated mechanisms of action and possible additional benefits to plants should be characterised in future investigations.
