Abstract A description is provided for Fusarium oxysporum f.sp. conglutinans. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Brassica oleracea (cabbage) and other Cruciferae: kale, Brussels sprouts, cauliflower, broccoli, kohlrabi, rutabaga, turnip, mustard, rape, Chinese cabbage, garden cress, stock, raddish. Armstrong & Armstrong (1952) consider the form infecting cabbage, raddish and stock as races of Fusarium conglutinans, however, Gordon (1965) recognizes these three as distinct formae speciales of Fusarium oxysporum, f.sp. conglutinans, f.sp. raphani Kendrick & Snyder and f.sp. mathioli Baker, respectively. DISEASES: Yellows of cabbage and other Cruciferae. GEOGRAPHICAL DISTRIBUTION: Africa (Congo, Cameroon, Rhodesia); Asia (China, Japan); Australasia (Australia, New Zealand); Europe (France, Netherlands, U.S.S.R.); N. America (U.S.A.); C. America and W. Indies (Cuba,? Trinidad); S. America (Brazil (Sao Paulo)) (CMI Map 54). TRANSMISSION: Soil-borne. Dissemination by means of soil on implements, transplants, surface drainage water and water-borne and wind-borne.

Abstract A description is provided for Fusarium oxysporum f.sp. vasinfectum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Gossypium spp., and species of Cajanus, Coffea, Hevea, Hibiscus, Medicago, Ricinus, Solanum and Vigna. DISEASE: Vascular wilt or Fusariosis of cotton is a disease affecting its host at all stages of its growth. Early symptoms on seedlings consist of vein clearing of the leaves followed by necrosis of the interveinal tissue and death of the leaves. On older plants leaves become chlorotic and the vascular tissues show a brown discolouration. Growth is retarded and the plant eventually wilts. GEOGRAPHICAL DISTRIBUTION: Africa: Congo, Central African Republic, Egypt, Ethiopia, Madagascar, Senegal, Somalia, Sudan, South Africa, Tanganyika, Uganda; Asia: Burma, China, Formosa, India, Indo-China, Iran, Iraq, Pakistan, U.S.S.R. ; Europe: France, Greece, Italy, Romania, Yugoslavia; North America, Mexico, U.S.A. (cotton belt); Central America & West Indies: Guatemala, Nevis, Nicaragua, Puerto Rico, Salvador, St. Vincent; South America: Argentina, Brazil, Chile, Colombia, Peru, Venezuela. (C.M.I. Map 362). TRANSMISSION: Soil-borne, but may also be transmitted by water and seed. The pathogen has been recovered from delineated seed obtained from infected cotton plants in the Central African Republic, Congo, Tanganyika and Brazil (32: 186; 33: 143; 40: 754; 41: 389). The percentage infection ranged from 0.2 to 5.0.

Abstract A description is provided for Fusarium oxysporum f. sp. ciceris. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cicer arietinum (gram, chickpea). DISEASE: Vascular wilt. GEOGRAPHICAL DISTRIBUTION: First recorded from India; subsequently reported from Bangladesh, Burma, Chile, Ethiopia, Iran, Malawi, Mexico, Pakistan, Peru, Spain, Sudan, Syria, Tunisia and USA.

Abstract A description is provided for Fusarium oxysporum f. sp. dianthi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Dianthus spp. (carnation, pinks, sweet williams), Lychnis chalcedoica L. (Caryophyllaceae) (Armstrong & Armstrong, 1954; Hood & Stewart, 1957). DISEASE: Vascular wilt. GEOGRAPHICAL DISTRIBUTION: Widespread where Dianthus is grown. TRANSMISSION: Via infected planting materials and contaminated soil. Local dispersal is by water flow and splash droplets containing slimy macro- or microconidia.

Abstract A description is provided for Fusarium oxysporum f.sp. cubense. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On cultivated banana and abaca (Musa spp.) and wild spp. of Heliconia (Musaceae), esp. H. caribaea (42: 80); three species of grass (Paspalum fasciculatum, Panicum purpurascens andlxophorus unisetus), and Commelina diffusa (Commelinaceae) may serve as alternative hosts (Waite & Dunlap, 1953).

America and W. Indies, N. & S. America (CMI Map 31). TRANSMISSION: Primarily soil-borne; possibly air-borne also. Pathogen may spread in infected leaf trash or soil and debris in surface flood-water.
