Application of chlorine dioxide (ClO2) and marine yeasts to control postharvest anthracnose disease in mango (Mangifera indica L.)

Abstract

Montiel. 2019. Application of chlorine dioxide (ClO 2 ) and marine yeasts to control postharvest anthracnose disease in mango (Mangifera indica L.). Cien. Inv. Agr. 46(3): 266-275. 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 (ClO 2 ) 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 ClO 2 inhibited the mycelium growth and spore germination of Colletotrichum gloeosporioides in vitro. When ClO 2 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 ClO 2 plus antagonist yeasts provides excellent control of anthracnose disease in Ataulfo mango fruits.

Natural Compounds and Derivates: Alternative Treatments to Reduce Post-Harvest Losses in Fruits

“…In recent years, the focus of technology and research in the agri-food sector has shifted towards products that allow an increase in crop yields, as well as improvements in quality during the pre-and post-harvest stages, utilizing natural, biodegradable, and environmentally benign active substances which do not negatively impact the environment, as established by the United Nations General Assembly in its 2030 Agenda [5,110].…”

Influence of Marine Yeast Debaryomyces hansenii on Antifungal and Physicochemical Properties of Chitosan-Based Films

“…On the other hand, antagonists have been used successfully for controlling important pathogens such as Colletotrichum gloeosporioides [15,16], Fusarium proliferatum [17], Botrytis cinerea [18], Penicillium digitatum [19] and Penicillium italicum [20]. Marine yeast Debaryomyces hansenii can control phytopathogens throughout several mechanisms of action such as the synthesis of hydrolytic enzymes (chitinase, glucanase, protease), competition for space and nutrients, production of killer toxins and biofilms onto the fruit surface, thus the use of antagonistic D. hansenii to manage fungal diseases is a promising alternative to chemical management [21][22][23].…”
