This comprehensive scientific review provides an in-depth analysis of both the natural compounds, pyrethrins, and their synthetic derivatives, pyrethroids, focusing on their classification, biosynthesis, mechanism of action, general and pharmaceutical uses, as well as their toxicity and environmental impact. Pyrethrins, derived from certain plant species, have long been recognized for their potent insecticidal properties. The review begins by examining the classification of pyrethrins and pyrethroids, elucidating their structural characteristics and unique features within the field of natural and synthetic compounds. The biosynthetic pathways responsible for producing pyrethrins in plants are discussed, highlighting the enzymatic reactions and genetic regulation involved. In addition, the synthesis of pyrethroid derivatives is explored, including both natural and synthetic sources and potential optimization strategies. Understanding the mechanisms of action by which pyrethrins and pyrethroids exert their insecticidal effects is a crucial aspect of this review. Complex interactions with the nervous systems of target organisms are examined, providing insights into their selective toxicity and modes of action. In addition, the various applications of these compounds are explored, from their use in agriculture for pest control to their incorporation into household insecticides and potential pharmaceutical applications. The review also critically evaluates the potential toxicity of pyrethrins and pyrethroids to human health. By consolidating current knowledge and research findings, this review provides a comprehensive understanding of the properties and applications of pyrethrins and pyrethroids, highlighting their benefits and risks, and the importance of responsible and sustainable use in various areas.

This research provides a comprehensive evaluation of the phytochemical composition, antioxidant potential, and biological properties of four plant species with longstanding use in ethnobotanical traditions: Calendula officinalis, Mentha × piperita, Urtica dioica, and Juglans regia. Plant extracts were obtained using a range of solvent systems and subsequently analyzed for their content of total polyphenols, flavonoids, and phenolic acids. Ultra-high-performance liquid chromatography coupled with mass spectrometry (UHPLC-MS) enabled the accurate identification and quantification of major polyphenolic constituents. The antioxidant capacity was assessed through a series of in vitro assays, and elemental analysis was conducted to determine microelement content. To evaluate potential ecological implications, acute toxicity was tested using Daphnia magna, while phytotoxic effects were also examined. The results demonstrate pronounced antioxidant activity along with notable biocidal and soil-enhancing properties. These findings underscore the potential of such plant-based formulations as sustainable alternatives to conventional agrochemicals and highlight the relevance of integrating traditional botanical knowledge with modern strategies for enhancing soil quality, crop performance, and environmental sustainability.

The purpose of this study was to develop a complex composition of a foliar liquid mineral fertilizer containing NPK macroelements and microelements including Fe, Mg, B, S, Zn, Cu, Mo, Ni, V, and Cr. This complex fertilizer aims to support the optimal development and maturation of maize crops, thereby enhancing both the quality and quantity of production. In our study, an original recipe was established for a complex composition of foliar liquid mineral fertilizer, and a technological process was developed in order to obtain the recipe at the laboratory level. The designed fertilizer was a complex mixture of fertilizers with herbicides with multiple purposes, which can be used in different pedo-climatic areas and which present, at the same time, low toxicity and minimal ecological impact. A wide-spectrum mixture DICOPUR TOP containing 2,4-D acid and Dicamba was chosen as a systemic herbicide which is absorbed by plants both in the root system and also on the leaves. For conditioning the complex mixture of fertilizers with herbicides, different types of polyvinyl alcohol with different degrees of hydrolysis were used. The liquid fertilizer mixture with DICOPUR TOP was applied over two years (2021 and 2022) to the Felix maize hybrid, demonstrating significant positive effects on grain yield while effectively controlling both dicotyledonous and monocotyledonous weeds.
