近十年香蕉黄叶病严重地威胁着台湾蕉产业,重灾地区植蕉时发病率高达30～40％。利用水田轮作,水稻2年后再植蕉,可使发病率降至5％以下,目前实际应用中已使发病率控制在10～15％,损失还是惨重。以高屏蕉园5,000公顷估算,每年约有100多万株得病,损失金额高达新台币2亿元之巨。引进和选育抗病品种成了最重要的一环,台湾香蕉研究所曾从国外引进大约170个香蕉 Banana leaf disease has threatened Taiwan’s banana industry seriously in recent ten years. The incidence of banana plantain in the hardest hit areas is as high as 30-40%. The use of paddy field rotation, rice replanting 2 years later, the incidence can be reduced to 5% or less, the current practice has been to control the incidence of 10 to 15% loss or heavy.
