Fungal disease. It damages fruit during storage, causing fruit rot; when it damages branches it is called gummosis. Harvesting fruit after rain or when humid, and not leaving a fruit stalk, favors the occurrence of this disease.Control methods: ① Clear the orchard in winter, and usually apply more lime and potassium fertilizer; strengthen spraying during the flowering and fruiting periods to reduce the amount of latent inoculum (the fungicides used for anthracnose control can be consulted). ② Harvest fruit on sunny days after the dew has dried, avoid mechanical injury, and leave a 1cm fruit stalk. ③ Within 24h after harvest, dip the fruit in a 1000-fold dilution of 25% prochloraz (miconazole) (31°C) for 2-5min, or dip the fruit in a 500-1000-fold hot solution (53±1°C) of 50% benlate or 50% thiabendazole for 10-15min.
