“…Especially, nanoformulations demonstrate high effectiveness due to both the ability to penetrate into plants as well as high specific surface area, increasing interaction with targets . It is assumed that due to the physical mode of action nanoparticles can contribute to combatting pathogen resistance to pesticides. − In general, controlled-release formulations, especially nanoformulations, can improve the targeting and cuticular penetration and are not easily led to pest resistance.…”

Pesticides are commonly used in modern agriculture and are important for global food security. However, postapplication losses due to degradation, photolysis, evaporation, leaching, surface runoff, and other processes may substantially reduce their efficacy. Controlled-release formulations can achieve the permeation-regulated transfer of an active ingredient from a reservoir to a target surface. Thus, they can maintain an active ingredient at a predetermined concentration for a specified period. This can reduce degradation and dissipation and other losses and has the potential to improve efficacy. Recent developments in controlled-release technology have adapted the concepts of intelligence and precision from the pharmaceutical industry. In this review, we present recent advances in the development of controlled-release formulations and discuss details of the preparation methods, material improvements, and application technologies.

“…A similar synergistic effect was reported for ZnO‐NPs when applied with the fungicide thiram in Phytophthora capsici 27 . To make things even more interesting, Ag‐NPs, Cu‐NPs and ZnO‐NPs have been shown to “neutralize” fungicide resistance when applied against benzimidazole or boscalid‐resistant isolates of B. cinerea , M. fructicola or A. alternata respectively; a profound synergistic effect was found when combining MNPs with fungicides that were otherwise ineffective due to target site resistance 3,9,10 …”

“…Nanotechnology has made a dramatic entrance into modern agriculture, providing novel means for improving crop production and protection introducing nanoparticles (NPs) as nano‐fertilizers, nano‐pesticides or as carriers for relevant active ingredients. Metal nanoparticles (MNPs), taking advantage of their unique physicochemical properties, have shown significant effectiveness in controlling numerous plant pathogens, both sensitive and drug‐resistant, requiring lower doses compared with their bulk/ionic protective counterparts 3 . The lower doses required for antimicrobial action and the potential to synthesize MNPs by green methods utilizing plants or microorganisms (or their metabolites) make them eco‐compatible alternatives to synthetic fungicides 4 .…”

Chemical control suffers from the loss of available conventional active ingredients due to strict environmental safety regulations which, combined with the loss of fungicide efficacy due to resistance development, constitute major problems of contemporary crop protection. Metal-containing nanoparticles (MNPs) appear to have all the credentials to be next-generation, eco-compatible fungicide alternatives and a valuable anti-resistance management tool. Could the introduction of MNPs as nano-fungicides be the answer to both reducing the environmental footprint of xenobiotics and dealing with fungicide resistance? The potential of MNPs to be utilized as nano-fungicides, both as alternatives to conventional fungicides or/and as partners in combating fungicide resistance, is discussed in terms of effectiveness, potential antimicrobial mechanisms as well as synergy profiles with conventional fungicides. However, their "golden" potential to be used both as alternatives and partners of conventional fungicides to combat resistance and reduce environmental pollution is challenged by undesirable effects towards non-target organisms such as phytotoxicity, toxicity to humans and environmental ecotoxicity, constituting risks that should be considered before their commercial introduction as nano-pesticides at a large scale.

“…Metallic nanoparticles synthesis, with approaches GRAS, is relatively cheap and does not require chemically hazardous reducing agents. Metallic nanoparticles have large surface area properties, a comprehensive action spectrum against pathogens (bacterial and fungus), a negligible risk for resistance development, and low cost [23]. Unlike bulk metal homologues, metal nanoparticles are effective due to the antimicrobial biochemical mechanism explaining the metallic-nanoparticles actions [89].…”

Nanopesticides are nanostructures with two to three dimensions between 1 to 200 nm, used to carry agrochemical ingredients (AcI). Because of their unique properties, the loading of AcI into nanoparticles offers benefits when compared to free pesticides. However, with the fast development of new engineered nanoparticles for pests’ control, a new type of environmental waste is being produced. This paper describes the nanopesticides sources, the harmful environmental and health effects arising from pesticide exposure. The potential ameliorative impact of nanoparticles on agricultural productivity and ecosystem challenges are extensively discussed. Strategies for controlled release and stimuli-responsive systems for slow, sustained, and targeted AcI and genetic material delivery are reported. Special attention to different nanoparticles source, the environmental behavior of nanopesticides in the crop setting, and the most recent advancements and nanopesticides representative research from experimental results are revised. This review also addresses some issues and concerns in developing, formulating and toxicity pesticide products for environmentally friendly and sustainable agriculture.
