Anthracnose disease caused by spp. makes heavy losses for post-harvest mangoes of Cat Hoa Loc variety during storage, packaging, and transportation. The synthetic fungicides are commonly used to control the disease, but they are not safe for consumers' health and environment. This study was aimed to investigate the use of essential oils (EOs) as the safe alternative control. Pathogen was isolated from the infected Cat Hoa Loc mangoes and identified by morphology and DNA sequencing of the ITS region. Six EOs (cinnamon, basil, lemongrass, peppermint, coriander, and orange) were chemically analyzed by GC-MS. The antifungal activity of EOs was studied in vitro and in vivo. The results showed that the isolated pathogen was . Cinnamon, basil, and lemongrass EOs effectively inhibited the growth of in descending order of cinnamon, basil, and lemongrass. However, they (except basil oil) severely damaged fruit peels. The antifungal activity was closely related to the main compounds of EOs. Basil EOs effectively controlled anthracnose development on Cat Hoa Loc mangoes artificially infected with , and its effectiveness was comparable to that of fungicide treatment. Consequently, basil EOs can be used as a biocide to control anthracnose on post-harvest Cat Hoa Loc mangoes.
由[病原菌名称未给出]引起的炭疽病，在储存、包装和运输过程中给“卡特霍阿洛克”品种的采后芒果造成了巨大损失。合成杀菌剂通常用于控制该病，但它们对消费者健康和环境不安全。本研究旨在探讨使用精油作为安全的替代防治方法。从感染的“卡特霍阿洛克”芒果中分离出病原菌，并通过ITS区域的形态学和DNA测序进行鉴定。通过气相色谱 - 质谱联用仪对六种精油（肉桂、罗勒、柠檬草、薄荷、香菜和橙子）进行化学分析。研究了精油在体外和体内的抗真菌活性。结果表明，分离出的病原菌是[病原菌名称未给出]。肉桂、罗勒和柠檬草精油按肉桂、罗勒、柠檬草的顺序有效抑制了[病原菌名称未给出]的生长。然而，它们（除罗勒油外）严重损害了果皮。抗真菌活性与精油的主要成分密切相关。罗勒精油有效控制了人工感染[病原菌名称未给出]的“卡特霍阿洛克”芒果上炭疽病的发展，其效果与杀菌剂处理相当。因此，罗勒精油可作为一种杀菌剂用于控制采后“卡特霍阿洛克”芒果上的炭疽病。
