中文摘要 | 設施內栽培之玫瑰,白粉病發生時期較露地栽培者長,而二種栽培環境之白粉病發生最嚴重時期皆在 2~3月間。調查 59個品種對白粉病之抗感性,發現其中有 16個品種不感病,而較感病 (罹病率 50~100%)的品種有 16個。田間藥劑試驗結果顯示, 50%保粒黴素 (甲) W.P. 5000倍、23.8%得克利 E.C. 2000倍、展著劑 CS-7 500倍、23%三泰隆 E.C. 2000倍、 29%核胺光動素 S.P. 1500倍、40%護矽得 E.C. 8000倍及25%依瑞莫 F.P. 1500倍等7種藥劑,對玫瑰白粉病具有良好防治效果。 |
英文摘要 | On greenhouse-growth rose, powdery mildew occurring period was longer than field-growth rose, but the most serious period was found from February to March on both growth condition. Fifty-nine rose cultivars were tested for their susceptibilities to powdery mildew. Among them, 16 cultivars were resistance and 16 cultivars were highly susceptible that the disease incidence of leaflets ranging from 50% to 100%. Field trials showed that 50% Polyoxins W.P., 23.8% Tebuconazole E.C., CS-7., 23% Triadimenol E.C., 29% Riboflavin + DL-methionine + Copper sulphate S.P., 40% Flusilazol E.C. and 25% Ethirimol F.P. were effective to control the rose powdery mildew. |
