Essential oils and their bioactive compounds as eco-friendly novel green pesticides for management of storage insect pests: prospects and retrospects

Essential Oil Nanoemulsion as Eco-Friendly and Safe Preservative: Bioefficacy Against Microbial Food Deterioration and Toxin Secretion, Mode of Action, and Future Opportunities

“…To address this issue, different international organizations such as the Food Chemical Codex, International Organization of Flavor Industries, Food and Drug Administration, Codex Alimentarium and the Council of Europe, and the Flavor and Extract Manufacturers Association have confirmed specific procedures for toxicological and chemical characterization of EOs. They also reported antagonistic and synergistic effects for specific EOs in mammals during practical application (Falleh et al, 2020;Chaudhari et al, 2021b). Generally, mammalian safety/toxicity of EOs and nanoemulsions were performed on experimental mice/rats which permits the determination of safety assessment in terms of Median Lethal Dose or LD 50 value.…”

Ferulago campestris Essential Oil as Active Ingredient in Chitosan Seed-Coating: Chemical Analyses, Allelopathic Effects, and Protective Activity against the Common Bean Pest Acanthoscelides obtectus

“…Viteri Jumbo et al [39] also observed a repellent activity against A. obtectus after the application of Cinnamomum zeylanicum EO at the doses of 46.8 and 122.4 µL/kg beans, very similar to the doses utilized in this experiment. The use of a polymer such as chitosan for the nanoencapsulation/nanoemulsion of EOs has already been investigated and tested against A. obtectus [40]. However, to the best of our knowledge, this is the first time that chitosan coating has been proposed with the addition of an OE with the aim of the protection of bean seeds for sowing in storage facilities.…”

A nanoemulsion of Rosmarinus officinalis L. essential oil with allelopathic effect against Lactuca sativa L. seeds / Uma nanoemulsão a partir do óleo essencial de Rosmarinus officinalis L com efeito alelopático em sementes de Lactuca sativa L

“…Several research has been showing its various applications, such as preserving stored foods by its pesticide action of oils, increasing the shelf life of foods by its protection against fungi and bacteria, and in agriculture, in weed control (Usman et al 2020). It is possible by the ease of nanoformulation dispersed products being readily soluble in water, enhanced bioefficacy, and controlled release (Chaudhari et al 2021). To date, only one study with nano encapsulated Rosmarinus sp essential oil has been presented with effect on germination in seeds of Amaranthus retroflexus and Raphanus sativus, allowing for the broad range of action with nanostructured products (Alipour et al 2019).…”

“…Superoxide ion dismutases (SODs) and H2O2 removing enzymes (Catalase and Peroxidases) are some of the enzymes involved in this process (Usman et al 2020). SODs are metalloenzymes, and they are considered a first-line defense against SROs, promoting superoxide ion (O2 -) dismutation into hydrogen peroxide (H2O2) and molecular oxygen (O2) (Mittler 2002;Nascimento et al 2020;Chaudhari et al 2021). Catalase (CAT) and Peroxidases (POX) act by removing the H2O2 generated by ORSs and also by other metabolic pathways, and thus act in a synchronized manner, ensuring greater tolerance to oxidative stress (Gill & Tuteja 2010;Verdeguer et al 2020).…”

“…Among the various nanotechnology applications in agriculture, an increasing alternative is nano-dispersion from plant actives to replace synthetic pesticides, which are very toxic and negatively affect the local ecosystem, causing enormous damage to the environment and human health. Therefore, essential oils have become one of the most studied plant derivatives for prospecting new pesticides of natural origin, having wide use in preparing nanostructured technological products for agricultural sector application (Chaudhari et al, 2021;Gahukar and Das, 2020).…”
