The flesh of the apricot first becomes brown with lesion expression. The lesion is mostly firm and leathery, with an uneven margin. Spore masses of an ash-grey / brown colour, cover the surface of the infected fruit, as the fungus progresses. The skin of the infected fruit readily slips away with a slight touch / sliding movement of one’s finger. This phenomenon is referred to as ‘slip-skin’. The decayed tissue does not separate easily from healthy tissue. Spread of decay to adjacent fruit is common during storage.
