• Anthracnose caused by Colletotrichum gloeosporioides is one of the most important postharvest diseases in mango fruit, often causing huge economic losses. In this study, the effect of 1-methylcyclopropene (1-MCP) against anthracnose in postharvest mango fruit and the mechanisms involved were investigated. 1-MCP induced reactive oxygen species (ROS) generation, damaged the mitochondria and destroyed the integrity of plasma membrane of spores of C. gloeosporioides, significantly suppressing spore germination and mycelial growth of C. gloeosporioides. 1-MCP also decreased the decay incidence and lesion expansion of mango fruit caused by C. gloeosporioides. For the first time this study demonstrated that 1-MCP suppressed anthracnose of postharvest mango fruit by directly inhibiting spore germination and mycelial growth of C. gloeosporioides, thus providing a promising strategy for disease control. •Antifungal activity of 1-MCP against anthracnose in postharvest mango fruit was investigated.•1-MCP decreased anthracnose caused by C. gloeosporioides in mango fruit.•1-MCP suppressed the spore germination and mycelial growth of C. gloeosporioides.•1-MCP induced reactive oxygen species (ROS) generation in spores of C. gloeosporioides.•1-MCP damaged the mitochondrial and integrity of plasma membrane of spores of C. gloeosporioides.
