Diseases of crop-plants in the Diseases of crop-plants in the Lesser Antilles diseasesofcroppl00nowe Year: 1923 242 DISEASES OF CROP-PLANTS it can be controlled and prevented from destructive spread by careful measures of quarantine. With Government assistance the infected areas are being planted with the immune ' Chinese ' banana to be prepared for export as a dried product. The disease exists to a serious extent on the Manzana variety but not the Chameluco in Cuba and on the Chameluco but not the Manzana in Porto Rico (Brandes) : in each case the most esteemed and most widely grown of the local kinds. An affection believed to be Panama disease prevents the cultivation of the Gros Michel on any large scale in Trinidad, but no adequate description has been published. A reference by Brandes to the existence of the disease in Barbados appears to be due to a misapprehension. A disease which closely resembles and may Fig. 89 Macroconidia of Fusarium vasinfectum. Exactly like those of F. cuBENSE IN Size and Shape From a drawing by C. W. Carpenter in Journal of Agricultural Research be identical with Panama disease seriously affects the Gros Michel in St. Lucia. In Central America the disease is present in Panama, Costa Rica, Nicaragua, Guatemala, Honduras, and British Honduras. In South America it occurs in Surinam and British Guiana; there is no evidence of its existence in the large banana-growing districts of Colombia, which are irrigated. In India a disease which appears to correspond in all respects with Panama disease is recorded as exterminating one kind of banana in a district of Bengal, while a disease different in its symptoms, but caused by a species of Fusarium has been described from Pusa. Affections similar in their nature to Panama disease occur in the Hawaiian Islands, Australia and the Dutch East Indies, and in the first named the identity of the fungus with Fusarium cubense has been established.
