Abstract A description is provided for Phoma caricae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Carica papaya. DISEASE: Black leathery rot of fruit, sunken bleached rot of young stems and leaf petioles and brown and white spot of leaves. On half-grown fruit the first visible symptom is a small circular water-soaked spot which slowly enlarges and darkens whilst the fruit is still immature but develops more rapidly as the plant tissues break colour. Within 2 weeks the lesion may reach 5 cm diam., become sunken and brownish-black in colour. On leaves, spots on both upper and lower surfaces are brown with a darker margin but gradually turn white as they dry out. On flowers the visible symptoms are brown decayed areas. GEOGRAPHICAL DISTRIBUTION: Africa (Ethiopia, Kenya, Mauritius, Rhodesia, Tanzania, Togo, Sudan, Zambia); Asia (India, Nepal, Thailand); Australasia & Oceania (Australia, New South Wales, Queensland, West Irian, Hawaii); Central America (Honduras); South America (Ecuador: Quito). TRANSMISSION: Probably by water splash and contact; infection through both wounded and unwounded surfaces (17, 627).
