A Newly Emerging Disease of Papaya in Ethiopia: Black Spot (Asperisporium caricae) Disease and Management Options

Endriyas Gabrekiristos

Papaya (Carica papaya L.) is an important fruit crop which is cultivated widely for consumption as a fresh fruit and for use in drinks, jams, candies and as dried and crystallized fruit. It has high nutritive and medicinal value. Papaya is also used as a source of cash-income. Production of papaya in Ethiopia is increasing through time; yet the average production and export is very low due to various abiotic and biotic factors. Among which, diseases cause much of the damage. Papaya is attacked by several diseases like, anthracnose, powdery mildew, black spot and papaya ring spot. Among the emerging diseases of papaya in Ethiopia, black spot disease caused by Asperisporium caricae is the most lethal by causing disease on photosynthetic and economic (fruit) plant parts. The fruits are affected on the surface, reducing the fresh-market value. In Ethiopia, Asperisporium caricae has been observed in most papaya producing areas. However, the severity of the pathogen has not been well profiled. The pathogen was not also characterized, which is the base to device management options. Currently, the use of fungicides and resistant cultivars are the preferred management options. This disease is found to be serious in the recent past few years by causing substantial economic loss. Therefore, the aim of this paper is to review the newly emerging black spot disease of papaya, its distribution and management options.
