台灣蘆筍立枯病及根腐病害之發生情形與要因之研究(第一年)

Abstract

調查本省苗栗、彰化、嘉義及屏東等4個縣主要蘆筍栽培鄉鎮共 11,201 處 (每處0.1公頃) 蘆筍田，發現根部病害周年平均發生率達 1.77-5.17%。其中 Fusarium oxysporum f.sp.asparagi 引起之立枯病約 46%，F. moniliforme 引起之根腐病約 17%，餘為其他病原菌如 F. Solani，Rhizoctonia solani 及 Pythium sp. 等所引起。 A survey on Fusarial wilt and other root diseases of asparagus was carried out from 11,201 fields located at 4 different asparagus growing prefectures in Taiwan in 1975. It was found that annual average of wilt and root disease reached as high as 1.77-5.17%. Among these diseased plants fourty-six percent were proved to be incited by Fusarium oxysporum f. sp. asparagi, 17% by F. moniliforme, and the rest of them by F. solani, Rhizoctonia solani and Pythium sp.
