Abstract A description is provided for Phomopsis caricae-papayae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Carica papaya (papaw or papaya or pawpaw). DISEASE: Stem rot and fruit rot of Carica papaya. Stem rot starts near the base or higher as well defined lesions spreading rapidly. In severe cases causes death of plants. On fruits the visible symptoms are water-soaked spot on the surface which increases on maturity. The infected area becomes depressed, dark brown to black and revealing cracks at an advanced stage (Dhingra & Khare, 1971). GEOGRAPHICAL DISTRIBUTION: Africa (Nigeria, South Africa), Asia (India, Pakistan), Australasia and Oceania (Australia, Queensland; Hawaii); West Indies (Dominican Republic, St. Lucia); South America (Brazil, Pernambuco; Venezuela). TRANSMISSION: The method of natural infection and factors which favour the spread of the disease have not been thoroughly studied. Presumably by conidia dispersed by water splash and the fungus survives on dry stems and leaf stalks.

Abstract A description is provided for Cercospora duddiae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Allium ascalonicum, A. cepa, A. fistulosum, A porrum, A. sativum. DISEASE: Leaf spot or withertip on onion and garlic. The symptoms vary on the different host species. On onion circular, chlorotic spots 3-5 mm diam. form mainly on the tip of the leaf, gradually decreasing in number towards the leaf base. The lesions at the leaf tip coalesce, forming a dry greyish-brown area, and in severe cases the entire leaf tip may be killed. The base of the leaf is mottled with brown necrotic leaf spots. Eventually the necrotic tissue may spread down the leaf surface, delimited by a narrow band (3 mm) of chlorotic tissue (Welles, 1923). Rarely does the disease cause much damage (Chupp & Sherf, 1960). GEOGRAPHICAL DISTRIBUTION: Africa: Mauritius, Nigeria, Sierra Leone, Somalia, Uganda; Asia: Borneo, Brunei, Burma, India, Indonesia, Oman, The Yemen; Australasia: Papua New Guinea; North America: West Indies (Barbados, Jamaica). TRANSMISSION: By air-borne or water-splash dispersed conidia, and by transportation with onion parts. The fungus is also reported to be seed borne (Chupp & Sherf, 1960).

Abstract A description is provided for Diplocarpon earliana. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Fragaria. DISEASE: Strawberry leaf scorch. GEOGRAPHICAL DISTRIBUTION: Throughout temperate zones and extending into the tropics in Malaysia, Taiwan, Australia and New Guinea; Africa (Rhodesia, Zambia, South Africa, Canary Islands); Europe (except Ireland, Spain, Sweden, Russia); North America (Canada, USA, Jamaica); South America (Brazil, Uruguay); Asia (Armenia, Cambodia, Hong Kong, India, Israel, Japan, W. Malaysia). Appears to be most important in USA and eastern Europe (CMI Map 452, ed. 1, 1969). TRANSMISSION: Mainly by splash dispersal of conidia from infected leaves. Ascospores appear to be unimportant and in some regions (Poland; 46, 2074) where the perfect state has not been found.
