Stemphylium Lycopersici

Abstract A description is provided for Stemphylium lycopersici. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Lycopersicon most commonly but also found on Allium, Carthamus, Gladiolus and other plants. DISEASE: Stemphylium leaf blight of tomato, petal blight of carnation. The fungus forms necrotic lesions, closely resembling those of grey leaf spot (S. solani), on foliage and floral parts in which conidia are borne in later stages of infection. Relatively severe attacks have been recorded on chrysanthemum in Canada (41, 309; 46, 3384) and tomato in Israel (53, 2683). GEOGRAPHICAL DISTRIBUTION: Asia (Arabia, Israel, Malaysia (W. and Sarawak), India, Hong Kong, Yemen); Africa (Kenya); N. America (USA, Canada); S. America (Venezuela); Central America and W. Indies (Cuba); Australasia and Oceania (Tahiti). TRANSMISSION: By air-borne conidia. Conidia have been shown to survive in dried plant refuse for 4 months and in dried agar culture for 8 months (Hannon & Weber, 1955).

Abstract A description is provided for Pestalotiopsis mangiferae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Mangifera indica; also on Anacardium occidentale, Combretum decandrum, Eucalyptus spp., Mimusops spp., Vitis vinifera and many other unrelated host plants. DISEASE: Grey leaf spot of Mangifera indica. The spots vary in size from a few mm to several cm in length, are usually sharply delimited by a dark, raised border, and are silvery grey above and grey to brown below; leaf spots on other hosts are similar. Brown spot or rot of mango fruits is also known. GEOGRAPHICAL DISTRIBUTION: Ghana, Nigeria, Sierra Leone, Tanzania, Uganda, Zaire, Zambia; Bangladesh, Brunei, Burma, Hong Kong, India, Malaysia, Nepal, Sabah, Solomon Islands, Sri Lanka; Australia; Dominican Republic; Venezuela. TRANSMISSION: Inoculation studies with conidia and mycelium have shown P. mangiferae to be a weak parasite, capable of infecting young injured leaves, injured fruits, older uninjured leaves and healthy fruits if in contact with diseased tissue (35, 378; 40, 421). It has been isolated from soil, but the possibility of transmission through soil has not been investigated.

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.
