    Abstract: 民國九十六年於金門地區栽植之高粱上發生嚴重植株萎凋死亡的問題。病株首先於莖部出現淡褐色不規則斑,隨著病斑擴大,顏色加深爲深紅褐色,病勢迅速進展,有時可見數片葉片乾枯,嚴重時整個植株乾枯萎凋。罹病莖部組織呈軟腐狀,縱切莖部其內部組織呈水浸狀褐化的病徵,罹病組織分離所得之病原細菌經柯霍氏法則、生理生化及專一引子Ec3F/4R增幅鑑定結果爲軟腐病菌Pectobacterium(原屬於Erwinia)chrysanthemi(Ech),屬biovar 3。以培養基抑制圈測試供試11種藥劑在一般推薦濃度下對該病原菌之生長均有抑制效果,其中又以歐索林酸及四環黴素抑制效果最顯著。
