Fusarium oxysporum f.sp. cubense. [Descriptions of Fungi and Bacteria].
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.
