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.

Abstract A description is provided for Greeneria uvicola. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Muscadine grapes (Vitis rotundifolia) are most susceptible; other grapes (Vitis vinifera, V. bourquina, V. labrusea, V. munsoniana) appreciably susceptible. Also recorded on apple (37, 241). Shown to be capable of invasion of fruits of apple, cherry, peach, strawberry, blueberry and banana (Ridings & Clayton, 1970). DISEASE: Bitter rot, ripe rot of grape, necrotic fleck of grapevine. GEOGRAPHICAL DISTRIBUTION: Europe (Greece); Asia (India, Hong Kong); North America (USA); Central America (Costa Rica); South America (Brazil); Africa (South Africa); Australia (Queensland). TRANSMISSION: By air-borne conidia. No information has been traced on the role of infected debris in spread and perennation of this fungus but the pathogen can carry over on infected first few internodes of the vine (5, 471).

Abstract A description is provided for Podosphaera leucotricha. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Malus spp., chiefly on M. pumila (apple), peach (Prunus persica), quince (Cydonia ualgaris) and Photinia spp. also attacked (Hirata, 1966). Also reported on almond fruit (43, 2544).
