Abstract：
Essential oils (EOs) extracted from aromatic and medicinal plants have the potential to inhibit the growth of various pathogens and, thus, be useful in the control of dangerous diseases. The application of environmentally friendly approaches to protect agricultural and forestry ecosystems from invasive and hazardous species has become more significant in last decades. Therefore, the identification and characterization of essential oils with a strong inhibitory activity against aggressive and widespread pathogens are of key importance in plant protection research. The main purpose of our study is to evaluate the impact of essential oils originating from different genotypes of bee balm, mint, and marigold on Botrytis cinerea, Fusarium solani, and Phytophthora pseudocryptogea. Twelve essential oils, including five EOs originating from Monarda fistulosa, one oil each from Monarda russeliana, Mentha longifolia, Mentha piperita, Tagetes patula, and Tagetes erecta, and two EOs from Tagetes tenuifolia were derived by steam or water distillation. The chemical composition of the tested EOs was determined by GS-MS analyses and their corresponding chemotypes were identified. The most effective against all three pathogens were determined to be the EOs originating from M. fistulosa and M. russeliana. B. cinerea, and P. pseudocryptogea were also significantly affected by the M. piperita essential oil. The most efficient EOs involved in this investigation and their potential to control plant pathogens are discussed.
摘要：
从芳香植物和药用植物中提取的精油(EO)具有抑制各种病原体生长的潜力,因此，有助于控制危险的疾病。在过去的几十年中，采用环境友好的方法保护农业和林业生态系统免受入侵和危险物种的侵害变得越来越重要。因此,对侵袭性和广泛性病原体具有强抑制活性的精油的鉴定和表征在植物保护研究中至关重要。我们研究的主要目的是评估源自不同基因型蜜蜂香脂的精油的影响，薄荷,和灰霉病菌上的万寿菊,镰刀菌,和假疫霉。十二种精油，包括来自Monardafistulosa的五个EO，每个来自MonardaRusseliana的油，长叶薄荷,薄荷胡椒,万寿菊,和万寿菊直立，并通过蒸汽或水蒸馏从万寿菊中提取了两种EO。通过GS-MS分析确定测试的EO的化学组成，并鉴定其相应的化学型。确定了对所有三种病原体最有效的是源自梭菌和罗氏分枝杆菌的EO。B.cinerea,和假胰头菌也受到M.piperita精油的显著影响。讨论了这项研究中涉及的最有效的EO及其控制植物病原体的潜力。
