Colletotrichum asianum (C. asianum) is a new pathogenic fungus that causes mango anthracnose. Cold plasma is a novel non-thermal decontamination technology, which has been proven to be effective in controlling postharvest fungus. Herein, dielectric barrier discharge (DBD) plasma was used to treat C. asianum spores in sterile phosphate-buffered saline, the damages in subcellular structures of C. asianum and inhibition of mango anthracnose were evaluated. Results showed that after 9 min treatment, the spore germination rate and spore viability were decreased by 95.48% and 98.82%, respectively, and the subcellular structures were damaged (P < 0.05), leading to spores death. Besides, DBD plasma treatments could control mango anthracnose and maintain mango quality, and the disease incidence and lesion diameter of mango treated for 9 min were decreased by 48.00% and 62.95%, respectively. Therefore DBD plasma inactivated C. asianum spore, providing an alternative technique for preventing and controlling mango anthracnose.
炭疽菌（Colletotrichum asianum）是一种引起芒果炭疽病的新型致病真菌。冷等离子体是一种新型非热消毒技术，已被证明可有效控制采后真菌。在此，使用介质阻挡放电（DBD）等离子体处理无菌磷酸盐缓冲液中的炭疽菌孢子，评估了对其亚细胞结构的损伤和对芒果炭疽病的抑制作用。结果表明，经过 9 分钟的处理，孢子的萌发率和孢子活力分别下降了 95.48%和 98.82%，亚细胞结构受到破坏（P<0.05），导致孢子死亡。此外，DBD 等离子体处理可控制芒果炭疽病并保持芒果品质，处理 9 分钟的芒果病发病率和病斑直径分别降低了 48.00%和 62.95%。因此，DBD 等离子体可使炭疽菌孢子失活，为防治芒果炭疽病提供了一种替代技术。
