Abstract

Postharvest diseases in fruits cause serious losses of fresh produce worldwide. The application of synthetic fungicides for the control of postharvest diseases such as anthracnose in mangoes can cause adverse effects on the environment and on human and animal health and has generated phytopathogen resistance. Biological control with the application of marine yeasts and chlorine dioxide (ClO2) to reduce the use of synthetic fungicides can be an alternative to prevent anthracnose in Ataulfo mango fruits. The results showed that different doses of ClO2 inhibited the mycelium growth and spore germination of Colletotrichum gloeosporioides in vitro . When ClO2 and the marine yeasts Debaryomyces hansenii and Rhodotorula minuta were applied to mango fruits, no signs of anthracnose disease incidence and lesion diameter were observed (LSD, p<0.05). Therefore, the application of ClO2 plus antagonist yeasts provides excellent control of anthracnose disease in Ataulfo mango fruits.

二氧化氯和海洋酵母防治芒果采后炭疽病的应用

水果采后病害在世界范围内造成了严重的新鲜农产品损失。应用合成杀菌剂防治芒果中的炭疽病等采后疾病会对环境和人类及动物健康造成不利影响，并产生植物病原体抗性。利用海洋酵母和二氧化氯(ClO2)进行生物防治，以减少合成杀菌剂的使用，可以作为防止Ataulfo芒果炭疽病的一种替代方法。结果表明，不同浓度的ClO2对炭疽菌菌丝生长和孢子萌发均有抑制作用。在芒果果实中施用ClO2和海洋酵母汉斯发酵菌和分钟红酵母时，没有观察到炭疽病发病率和病变直径的迹象(LSD, p<0.05)。因此，应用ClO2 +拮抗酵母对Ataulfo芒果炭疽病有很好的防治效果。
