香蕉丝核腐烂病是由立枯丝核菌侵染香蕉组培苗引起的一种真菌性新病害。近年已在广西南宁、隆安、邕宁、武鸣、田东等县(市)的香蕉组培苗大棚生产基地中发生,造成较大的经济损失。成为香蕉组培苗大棚生产的重要病害。病害初次侵染来源于带病的泥土、肥料及曾被感染的其他植物病残体。高温高湿利于病害的发生发展。据此,作者提出如下防治措施: 供育苗用的营养杯泥和农家肥应选用老塘泥和腐熟的有机肥;禁止在残留有水稻纹枯病残体的地方拌泥装杯;禁止用稻草作育苗棚遮阴物,尽可能减 Banana filamentous rot is a new fungal disease caused by Rhizoctonia solani infection of banana tissue culture seedlings. In recent years, Guangxi Nanning, Long’an, Suining, Wuming, Tiandong and other counties (cities) banana tissue culture greenhouse production base occurred, resulting in greater economic losses. Become a banana tissue culture greenhouse production of important diseases. The initial infestation of the disease comes from diseased soil, fertilizers and other plant diseases that have been infected. High temperature and humidity conducive to the occurrence of disease development. Accordingly, the author put forward the following prevention and control measures: Nutritional cup mud and farmyard manure used for raising seedling should use old pond mud and decomposed organic fertilizer; Prohibit paddy clinging cups where residual rice sheath blight remains; Prohibit the use of straw For nursery shelter shade, as much as possible
