Weeds cause a decrease in the quantity and quality of agricultural production and economic damage to producers. The prolonged use of synthetic pesticides causes problems of environmental pollution, the possible alteration of agricultural products and problems for human health. For this reason, the scientific community's search for products of natural origin, which are biodegradable, safe for human health and can act as valid alternatives to traditional herbicides, is growing. Essential oils can have useful implications in agriculture by acting as effective alternatives to chemical herbicides. In this work, the chemical composition of an EO from - and its herbicidal properties were studied on two weeds ( and ) and two crops ( and ) and its environmental safety was also assessed using three model organisms: sp., and . The principal component of the EO was camphor (26.02%), with α- and β-thujone (9.60 and 8.38%, respectively), 1,8-cineole (8.02%), piperitenone (5.29%) and camphene (4.95%) as the main components. The EO demonstrated variable phytotoxic effects with a dose-dependent manner, inhibiting both the germination and the radical elongation of the tested seeds, and was also found to be environmentally safe for the selected organisms. The results lay the foundation for considering this EO as a potential weed control agent.
杂草会导致农业产量和质量下降，并给生产者造成经济损失。长期使用合成农药会引发环境污染问题、农产品可能发生变化以及对人类健康产生问题。因此，科学界对天然来源产品的探索不断增加，这些产品可生物降解、对人类健康安全，并且能够作为传统除草剂的有效替代品。精油可作为化学除草剂的有效替代品，在农业中具有有益作用。在这项研究中，对来自[植物名称]的一种精油的化学成分及其对两种杂草（[杂草名称1]和[杂草名称2]）和两种作物（[作物名称1]和[作物名称2]）的除草特性进行了研究，并使用三种模式生物：[生物名称1]属、[生物名称2]和[生物名称3]评估了其环境安全性。该精油的主要成分是樟脑（26.02%），主要成分还有α-和β-侧柏酮（分别为9.60%和8.38%）、1,8-桉叶素（8.02%）、胡椒酮（5.29%）和莰烯（4.95%）。该精油表现出剂量依赖性的不同植物毒性效应，抑制了受试种子的萌发和胚根伸长，并且还被发现对所选生物具有环境安全性。这些结果为将这种精油视为一种潜在的杂草控制剂奠定了基础。
