BACKGROUND Mangoes are tropical fruits appreciated worldwide but are extremely perishable, being susceptible to decay, pest infestation and fungal diseases. Using the flavorful and highly valued ‘Manila’ cultivar, we examined the effect of second‐generation chitosan coatings on shelf‐life, phenolic compound variation, phytohormones, pest infestation by fruit flies (Anastrepha obliqua) and anthracnose disease caused by the fungus Colletotrichum gloeosporioides. RESULTS We observed almost total elimination of A. obliqua eggs with 10 and 20 g L−1 chitosan in diluted acetic acid and a five‐ to sixfold reduction in anthracnose damage. Treatment with 20 g L−1 chitosan also extended the shelf‐life. External (skin) and internal (pulp) discoloration processes were delayed. Fruit firmness was higher when compared with control and acetic acid treatments, and total soluble solids were lower in chitosan‐treated fruit. Targeted and non‐targeted metabolomics analyses on chitosan‐coated fruit identified some phenolic compounds related to the tannin pathway. In addition, abscisic acid and jasmonic acid in the peel were downregulated in chitosan‐coated mango peels. Both phytohormones and phenolic content may explain the reduced susceptibility of mangoes to anthracnose development and A. obliqua egg eclosion or larval development. CONCLUSIONS We conclude that chitosan coatings represent an effective postharvest treatment that significantly reduces anthracnose disease, inhibits A. obliqua egg eclosion and significantly extends ‘Manila’ mango shelf‐life, a key factor currently inhibiting large‐scale commercialization of this valuable fruit. © 2020 Society of Chemical Industry

“…Among the several factors that directly or indirectly affect post-harvest losses, the diseases caused by phytopathogenic fungi in a quiescent manner stand out, which cause great inconvenience to wholesalers, retailers and, above all, to fruit exporters and importers, such as those from mango fruits (Terao et al, 2013). Anthracnose, a disease caused by fungi of the genus Colletotrichum, is of great importance in the post-harvest of different vegetables, Colletotrichum gloesporioides being the species that causes the greatest economic losses in mangoproducing areas, reaching 100% losses in areas of tropical and humid climate in the world (Kamle & Kumar, 2016). In regions with semi-arid climate and/or with low rainfall, where the largest planted area of this fruit is found (Lima et al, 2018), anthracnose is of less importance, concentrating in the rainiest months.…”

This work aimed to perform the molecular identification of fungi mango fruits, in addition to verifying the effect of the essential oils for microbial control. Pericarp segments containing injured and healthy areas of mango fruits were initially disinfested, and then incubated in PDA culture medium at 25 °C. From all isolated material, UDC03, UDC04, UDC09 and UDC12 were preselected, which presented homogeneous cultures. The UDC04 and UDC12 isolates were submitted to the sequencing of the ITS region for presenting mycelial growth both greater and morphologically distinct of fungi from Colletotrichum genus. When BLAST is used in species identification, it was observed that UDC04 and UDC12 belong to Botryosphaeria dothidea and Neofusicoccum parvum, respectively. Regarding the control of UDC04, it was observed that BDA culture medium containing 1.5 to 2% of lemongrass and eucalyptus oils resulted in complete inhibition. For UDC12, mycelial growth inhibition was detected with the use of 1% and 1.5% essential oils of eucalyptus and lemongrass, respectively. The chia essential oil was not effective for the isolates control. Finally, the results reveal the importance of molecular identification of these phytopathogens associated with the establishment of an alternative control of fruits due to problems of contamination with chemical products.

“…Colletotrichum gloeosporioides is a dangerous phytopathogen threatening global plant productivity in a wide range of species, including horticultural crops (fruits, vegetables, and flowers), cereals, and grasses [ 1 , 2 ]. Mango anthracnose caused by C. gloeosporioides is one of the most dominant and destructive diseases that has emerged in the field and postharvest storage, resulting in severe rot and huge economic losses worldwide [ 3 ]. Synthetic fungicides (e.g., prochloraz, difenoconazole, carbendazim, and azoxystrobin) have been typically used as preventive and curative measures to control the infection of C. gloeosporioides [ 4 ].…”

We investigated alpha-mangostin (α-mangostin, α-MG), a xanthone natural product extracted from the pericarp of mangosteen (Garcinia mangostana), for its antifungal activities and possible mechanism against Colletotrichum gloeosporioides, which causes mango anthracnose. The results demonstrated that α-MG had a relatively high in vitro inhibitory activity against C. gloeosporioides among 20 plant pathogenic fungi. The median effective concentration (EC50) values of α-MG against mycelial growth were nearly 10 times higher than those of spore germination inhibition for both strains of C. gloeosporioides, the carbendazim-sensitive (CBD-s) and carbendazim-resistant (CBD-r). The results suggested that α-MG exhibited a better inhibitory effect on spore germination than on the mycelial growth of C. gloeosporioides. Further investigation indicated that the protective effect could be superior to the therapeutic effect for mango leaves for scab development. The morphological observations of mycelium showed that α-MG caused the accumulation of dense bodies. Ultrastructural observation further revealed that α-MG caused a decrease in the quantity and shape of the swelling of mitochondria in the mycelium cells of C. gloeosporioides. In addition, bioassays disclosed that the inhibitory activity of α-MG on spore germination was reduced by adding exogenous adenosine triphosphate (ATP). These results suggested that the mode of action of α-MG could be involved in the destruction of mitochondrial energy metabolism. The current study supports α-MG as a natural antifungal agent in crop protection.
