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. 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). DISEASES: Panama disease (vascular wilt) of banana (banana wilt) and vascular wilt in abaca (Musa textilis). GEOGRAPHICAL DISTRIBUTION: Widespread: Africa, Asia, Australasia and Oceania, C. 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. Infected planting material is another source of infection and spread.

Abstract A description is provided for Fusarium oxysporum f.sp. melonis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cucumis melo. DISEASE: Causes a destructive wilt of muskmelon and cantaloupe. The casaba or winter melon is resistant (e.g. var. Honey Dew). Infection occurs on seedlings (pre-emergence and post-emergence damping-off) and older plants (leaf chlorosis, stunting and generai wilt). Streaks appear on the stems up to 0.6 m long; they become necrotic and bear the salmon-pink sporulating masses. In some cases stem cracks develop and a brownish exudate forms. The vascular elements become orange-red and the fruit is much reduced in size. The formae speciales of F. oxysporum from muskmelon and watermelon (Citrullus lanatus) will each attack the seedlings of both hosts, but older plants are susceptible only to their own f.sp. Generally the virulence of a given isolate is greater on its original host (12: 744; 27: 307; 31: 473; Leach, 1936). Cucumber (Cucumis sativus) and marrow (Cucurbita pepo) are resistant (39: 117). GEOGRAPHICAL DISTRIBUTION: Generai in North America (U.S.A., Canada) and Europe. Also reported from Asia (Formosa, Iraq, Japan, Philippines) and Australasia (Australia). TRANSMISSION: Through soil and seed (Leach, 1936).

Abstract A description is provided for Alternaria cucumerina. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Citrullus lanatus, Cucumis melo, C. sativus, Cucurbita spp. DISEASE: Leaf spot of cucumber and melon (watermelon, musk melon, cantaloupe). Symptoms begin as yellow-brown flecks, 0.5 mm diam., on the upper surface of usually the crown leaves. They have a light green halo and gradually enlarge, becoming coalescent, with concentric ringing more commonly on the upper surface. Death of the leaves can be followed by lesions, several cm diam., forming on ripe fruit. These become covered with a dark, olive-green, conidial mass; they may be sunken and also show the concentric zonation. Infection of fruit in the field may be aggravated by exposure to sunlight (10: 431). Infection of stems or petioles does not occur. The pathogen can also cause decay in transit and storage, especially of melons and squash. GEOGRAPHICAL DISTRIBUTION: Arabia, Australia, Canada, Chile, Cuba, Cyprus, England, France, Japan, Kenya, Libya, Mozambique, New Zealand, Nigeria, Rhodesia, Rumania, Sierra Leone, South Africa, Sudan, Thailand, Trinidad, U.S.A., Venezuela, Zambia. TRANSMISSION: Seed may become contaminated with conidia. Survival from season to season is probably through mycelium in host debris. No air dispersal studies have been reported.
