分布和历史椰子败生病(Cadangcadang)目前只局限在菲律宾的某些地区,世界其他地方还没有发生此病的报道。1926年菲律宾圣米格尔岛最先报道发生此病。到1950年,比科尔半岛的四个省都发生此病。现已蔓延到东北的卡坦端内斯省,南则已到马斯巴特和北部海岸以及萨马的东南端。(译注:从分布图看,此病主要分布在菲律宾群岛的中部)。在比科尔半岛上,此病至少发生在42个类型的土壤区内。分布于小山顶、山坡、山谷和滨海。
Distribution and History Cadangcadang is currently confined to certain parts of the Philippines and the disease has not been reported elsewhere in the world. 1926 Philippines San Miguel Island was the first reported incidence of the disease. By 1950, the disease occurred in all four provinces of the Bicol Peninsula. It has now spread to the province of Catanduanes, in the northeast, to the south of Masbat and to the north coast and to the south-eastern tip of Sama. (Annotation: view from the distribution chart, the disease is mainly distributed in the middle of the Philippine archipelago). In the Bicol Peninsula, the disease occurs in at least 42 types of soils. Distributed in the hilltops, slopes, valleys and coastal.
