Inhibition of Colletotrichum gloeosporioides and Control of Postharvest Anthracnose Disease on Mango Fruit Using Propionic Acid Combined with Bee-Carnauba Wax Emulsion

Do Chi Thinh, Kaewalin Kunasakdakul


Anthracnose caused by Colletotrichum gloeosporioides is the most significant postharvest disease of mangos and negatively affect handling and marketing of mango fruits in Vietnam. A mixture of bee-carnauba wax and propionic acid has successfully inhibited linear growth and spore germination of C. gloeosporioides (in vitro) and prevented anthracnose diseases of mango fruits (in vivo). A complete reduction in mycelial growth and spore germination was observed when a mixture of 0.09% propionic acid and 8% bee-carnauba wax was used. Similar results were shown on mango fruits treated with 0.12% propionic acid which obtained a highly protective effect against anthracnose disease. The results of this study revealed that propionic acid could be used as a safe fungicide alternative against anthracnose disease, which causes economic losses during transportation, marketing and storage.
