Abstract A description is provided for Cercospora carbonacea. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Dioscoria spp. DISEASE: Leaf spot of yams. Causes fairly large, 5-20 mm, angular leaf spots, which are usually delimited by the leaf veins. The dark brown to almost black leaf spots give an almost charred appearance to the leaves, while on the lower surface the spots are grey becoming brown with age. GEOGRAPHICAL DISTRIBUTION: Africa: Ethiopia, Ghana, Guinea, Nigeria, Sierra Leone, Tanzania, Togo, Asia: Burma, India, North America: Canada (Ontario), West Indies (Barbados, Grenada, Jamaica, St. Vincent, Puerto Rico, Trinidad); South America: Venezuela.

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).

B. abyssinica: Abyssinian kale). DISEASE: Found associated with pale brown, often dark bordered leaf spots. GEOGRAPHICAL DISTRIBUTION: Africa (Kenya, Malawi, Mauritius, Nigeria, Sierra Leone, Sudan, Tanzania, Togo, Uganda), Asia (Burma, India, Malaya, Sri Lanka), East Indies (Papua New Guinea, Philippines, Sabah, Sarawak, Solomon Islands), West Indies (Antigua, Trinidad).

Abstract A description is provided for Cercospora beticola. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Beta ciclae, B. maritima (wild sea beet), B. putternulaei, B. trigyna, B. vulgaris (beet, sugar beet), Chenopodium ambrosioides (wormseed), C. beticola, C. murale, C. polyspermi, C. urbicum, Spinacea oleracea (spinach). DISEASE: Causing whitish, grey or pale brown spots usually surrounded by a narrow reddish-purple or brown border on living and wilting leaves. GEOGRAPHICAL DISTRIBUTION: Africa (Ethiopia, Kenya, Libya, Malawi, Mauritius, Nigeria, Sierra Leone, Sudan, Tanzania, Togo, Uganda, Zambia, Zimbabwe), Asia (Hong Kong, India, Malaya, Nepal, Pakistan), East Indies (Borneo, Papua New Guinea), Europe (Channel Isles, Cyprus, Czechoslovakia, England, France, Germany, Italy, Malta, Poland, Roumania, Switzerland), Middle East (Iran, Iraq, Israel, Jordan, Oman, Turkey), North America (USA), South America (Venezuela), West Indies (Antigua, Cuba, Jamaica). TRANSMISSION: Wind dispersal of conidia showed diurnal periodicity with a peak at 10.00 hrs. The increase in concentration of conidia above the crop coincided with an increase in wind speed and temperature and a decrease in RH. The largest number of conidia were trapped on warm dry days following rain or overnight dew (50, 362). Epiphytotics were proceeded by periods of 6h at more than 90% RH for 3-4 successive days and at a temperature of more than 12.5°C (55, 1205).

Abstract A description is provided for Cercospora malayensis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Hibiscus abelmoschus (musk mallow), H. cannabinus (deccan hemp), H. esculentus (okra), H. fisculatus, H. mutabilis, H. sabdariffa, H. suranensis, Euphorbia pulcherrima, Sphaeralcea cisplaniina. DISEASE: Leaf spot or brown leaf spot of Hibiscus spp. The first symptoms are yellowish patches on the leaf surface. These then become necrotic and gradually expand into irregular greyish brown leaf spots with dark brown to purple borders, surrounded by a pale yellow halo. Ultimately the necrotic areas become shrivelled and crack (30, 445). GEOGRAPHICAL DISTRIBUTION: The fungus is found wherever Hibiscus is cultivated (Chupp & Sherf, 1960). Africa: Ethiopia, Ghana, Mauritius, Sierra Leone, South Africa, Sudan, Tanzania, Uganda, Zimbabwe; Asia: Borneo, India, Indonesia, Japan, Malaysia, Philippines; Australasia: Fiji, Papua New Guinea; North America: West Indies (Jamaica, Trinidad, Cuba); South America: Colombia, Venezuela. TRANSMISSION: Presumably by wind-borne and rain-splash dispersed conidia.
