Ecology and Control of Fusarial Wilt of Banana

Abstract

Fusarial wilt of banana (Musa AAA 'Giant Cavendish' and 'Robusta'). caused by Fusarium oxysporum f. sp. cubense race 4, is affecting more than 1,500 hectares of banana plantations annuallyn in Taiwan. Cases per year increased from 1,500 in 1968 to more than 500,000 in 1983. The fungus was widely distributed in Pingtung and Kaohsiung counties, and also appeared sporadically in Changhua, Nantu, and Chia-I counties. 目前臺灣香蕉發生黃葉病 (病原菌：Fusarium oxysporum f. sp. cubense生理小種4) 的蕉園面積每年達1,500公頃以上，發病株數於1968年僅有1,500株，到1983年增至500,000株。本病病原菌普遍分佈於高、屏兩縣，局部性分佈於彰化、南投、和嘉義等縣。本病遠距離傳播主要以流水和病苗為媒介，在蕉園內則可依賴灌溉水，除萌作業和種植病苗而擴散。
