Abstract A description is provided for Fusarium oxysporum f.sp. tracheiphilum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Glycine max, Vigna sinensis and V. unguiculata. DISEASE: A fairly widespread disease of both soyabean and cowpea and generally most serious in U.S.A. In cowpea the leaves become flaccid and chlorotic; in young plants a fairly rapid wilt can occur and leads to death. On older plants infection causes stunting, and chlorosis precedes leaf fall and a gradual wilt. The vascular tissue is necrotic and the roots may be more severely diseased than the above-ground symptoms suggest. The lower stem may become swollen before any chlorosis occurs. In the woody soyabean a generai wilt is not usually found. The plants become stunted, with the ehlorotic leaves gradually falling. Death ensues later than in the case of cowpea. Internal stem necrosis is a conspicuous symptom and removal of the petioles reveals this. Although the fungus chiefly causes the typical vascular disorders of this pathogenic group, there are reports of soyabean pod infection from Japan (19: 453). Infection of cowpea in India has also been described (35: 503). Some isolates from cowpea have proved pathogenic to bean (Phaseolus vulgaris) and it has been suggested that isolates of Fusarium oxysporum f.sp. phaseoli might be virulent towards cowpea (43, 1472). GEOGRAPHICAL DISTRIBUTION: North America (Canada (Ontario) and in U.S.A., on cowpea, general in the southern states; on soyabean it occurs from Florida, La, Texas, Neb. and California); South America (Colombia); Asia (Formosa, India, U.S.S.R.); Australasia (Australia). Reports of its presence in Central Africa require confirmation. TRANSMISSION: Through soil and probably seed (11: 220; 29: 453).

Abstract A description is provided for Fusarium oxysporum f.sp. phaseoli. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Phaseolus vulgaris (common bean), P. coccineus (scarlet runner bean). May also infect some lupin varieties (Armstrong & Armstrong, 1963). Not pathogenic to other types of beans such as Lima beans (P. limensis var. limenanus), cowpea (Vigna sinensis[Vigna unguiculata]) or soyabeans (Soja max[Glycine max]). DISEASE: Fusarium Yellows, vascular wilt. GEOGRAPHICAL DISTRIBUTION: Widespread where Phaseolus vulgaris is grown, including Brazil, Czech Republic, China, Colombia, Costa Rica, Egypt, Greece, Italy, Japan, Kenya, Mexico, Peru, Poland, Rwanda, Slovakia, The Netherlands, UK, USA, (former) Yugoslavia. TRANSMISSION: Conidia are dispersed locally by water flow and splash droplets. Chlamydospores may be dispersed by movement of contaminated soil or plant debris. The fungus is also seed-borne by conidial contamination (Kendrick, 1934).

Abstract A description is provided for Fusarium oxysporum f.sp. elaeidis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Elaeis guineensis. DISEASE: A vascular wilt of the oil palm was first reported from Africa (26: 103; 28: 124). In young palms the first symptom is an extensive chlorosis in some of the central leaves (4th-15th). This is followed by leaf necrosis (giving a flat-topped appearance) and death within a year. In mature palms leaf wilt and necrosis and breaking of the rachis may be rapid, causing death in a few months (acute form). But in the chronic form the progressive dying of the crown inwards may be very slow with new, though smaller, leaves being produced. The vascular tissue in roots and stems becomes orange, darkening progressively to black. It is very characteristic of the disease that the internal necrosis is restricted to the xylem region. Elaeis madagascariensis and E. melanococca have also been found to be affected (37: 52). GEOGRAPHICAL DISTRIBUTION: First found in the Congo, then later in Nigeria (27: 523), Cameroon (40: 148) and Colombia (46, 3389). TRANSMISSION: Presumably through soil.

Callose (β-1,3-glucan) was localized with the electron microscope in the contact cells surrounding vessels of tomato and cotton infected with Fusarium oxysporum by means of gold labelling with a polyclonal antiserum to β-1,3-glucan. The callose was deposited in the apposition layers formed after infection in the cells surrounding initially infected vessels. Callose was not detected in the contact cells surrounding secondarily infected vessels. Callose could be detected in the contact cells of resistant and susceptible tomato cultivars 4 h after inoculation. Key words: β-1,3-glucans, contact cells, gold labelling, Gossypium, Lycopersicon esculentum.

Abstract A description is provided for Septoria glycines. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Glycine max. DISEASE: Brown spot of soyabean (Glycine max). Early symptoms are usually on the cotyledons and first true leaves, spots are redish-brown, somewhat angular, up to 5 mm diam. and very numerous. They spread acropetally, coalesce and result in defoliation. Spots appear on stems and pods, which bear pycnidia (6: 74). GEOGRAPHICAL DISTRIBUTION: Occurs in E. Asia (China, Japan, USSR), and parts of E. and central Canada and USA (CMI Map 361, ed. 1, 1958). An additional record not yet mapped is Colombia. TRANSMISSION: Largely by seed which is penetrated mostly via the placenta and funicle; seed bears necrotic areas and pycnidia (35: 66; 37: 199).

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.
