甘蔗夙梨病(Ceratocystis paradoxa(de Seynes)Moreau)是甘蔗种苗的毁灭性大病害。它广泛分布于世界各热带蔗区,我国的台湾、广东、广西和福建等省(区)也都普遍发生。 一九五八年以来,海南岛大量引进感病品种台糖134,又加上忽略了蔗田的卫生工作,致使甘蔗夙梨病在北部蔗区蔓延扩展十分迅速。种苗发病率相当高,甚至出现不少全田死亡的失败事例。海南甘蔗试验站在一九五八至一九六一年对夙梨病的发生情况及防治途径进行了试验研究,兹将所获结果以及我们对防治甘蔗夙梨病的一些看法叙述如下。
Ceratocystis paradoxa (de Seynes) Moreau is a devastating disease of sugarcane seedlings. It is widely distributed in various tropical sugar cane regions in the world. It is also common in the provinces (regions) of Taiwan, Guangdong, Guangxi and Fujian in China. Since 1958, the introduction of a large number of susceptible cultivars, Taiwan Sugar 134, in Hainan Island, coupled with the neglect of sanitary work on sugar cane fields, has caused the rapid spread of sugar cane pear diseases in the northern sugar cane area. The incidence of seedlings is quite high, and even many failed cases of death in the whole field. Hainan Cane Experiment Station in 1958 to 1961 the incidence of pear diseases and prevention and control of the pilot study conducted, the results we get and we are some of the views on the prevention and control of sugarcane pear pear diseases are described below.
