Essential oils (EOs) are a natural source of active compounds with antifungal, antimycotoxigenic, and herbicidal potential, and have been successfully used in organic agriculture, instead of chemical compounds obtained by synthesis, due to their high bioactivity and the absence of toxicity. The aim of this study was to highlight the importance of essential oil (CEO) as a potential source of bioactive constituents and its applications as an antifungal and bioherbicidal agent. The CEO was obtained by steam distillation of coriander seeds and GC-MS technique was used to determine the chemical composition. Furthermore, in vitro tests were used to determine the antifungal potential of CEO on mycelia growth through poisoned food technique, resulting in the minimum fungistatic (MCFs) and fungicidal concentrations (MCFg). The antifungal and antimycotoxigenic effect of CEO was studied on artificially contaminated wheat seeds with spores. Additionally, the herbicidal potential of CEO was studied by fumigating monocotyledonous and dicotyledonous weed seeds, which are problematic in agricultural field crops in Romania. The in vitro studies showed the antifungal potential of CEO, with a minimum concentration for a fungistatic effect of 0.4% and the minimum fungicidal concentration of 0.6%, respectively. An increase in the antifungal effects was observed in the in vivo experiment with , where a mixture of CEO with essential oil (SEO) was used. This increase is attributed to the synergistic effect of both EOs. Moreover, the synthesis of deoxynivalenol (DON)-type mycotoxins was found to be less inhibited. Hence, CEO has shown an herbicidal potential on weed seeds by affecting inhibition of germination.
精油（EOs）是具有抗真菌、抗真菌毒素和除草活性的天然化合物的来源，并因其高生物活性和无毒而成功地用于有机农业，替代了通过合成获得的化学化合物。本研究旨在强调精油（CEO）作为生物活性成分的潜在来源的重要性及其作为抗真菌和生物除草剂的应用。通过蒸汽蒸馏从芫荽种子中获得 CEO，并使用 GC-MS 技术确定其化学成分。此外，还通过毒饵法测定了 CEO 对菌丝生长的体外抗真菌潜力，得出了最小抑菌浓度（MCFs）和最小杀菌浓度（MCFg）。通过在人工污染的小麦种子上研究 CEO 的抗真菌和抗真菌毒素作用，研究了 CEO 的抗真菌和抗真菌毒素作用。在罗马尼亚农业大田作物中存在问题的单子叶和双子叶杂草种子上研究了 CEO 的除草潜力。体外研究表明 CEO 具有抗真菌潜力，抑菌作用的最小浓度为 0.4%，最小杀菌浓度为 0.6%。在体内实验中，当使用 CEO 与 SEO 的混合物时，观察到抗真菌作用的增加。这种增加归因于两种 EO 的协同作用。此外，发现 DON 型真菌毒素的合成受到的抑制较少。因此，CEO 对杂草种子表现出除草潜力，通过影响发芽抑制来发挥作用。
