中文摘要 | 91年1月發現林業試驗所六龜研究中心之六龜研究中心之樹木標本園遭受褐根病危害,受害樹木種類計有桃花心木,巴西橡膠樹、卡鄧柏、銀樺、欖仁、竹柏及火焰木。對於已枯死樹木砍伐並以挖土機除去殘根,而初期被感染且尚未枯死的桃花心木,嘗試以外科手術方式進行處理。切除被感染的概部組織,並且以銅快得寧稀釋500倍進行傷口淋洗處理,樹木週遭土壤以三泰芬及銅快得寧進行灌注處理。褐根病屬於快速萎凋病,一般觀察及文獻記載遭褐根病感染之樹木從感染發病到完全枯萎約3個月的時間,以外科手術及藥物處理的桃花心木,經16個月後,原植地上部黃化枯萎的枝幹,已長出新的枝葉並不再產生不正常落葉情形,判斷應已恢復健康。 |
英文摘要 | Tree specimen garden of Lkukuei Research Center was endangered by tree brown root disease on January 2002. the infected tree species included Swietenia mahogoni (L.) Jacq., Castilla elastica Cerv., Catalpa speciosa Warde ex Ergelm, Grevillea robusta A. Cunn., Terminalia catappa Linn., Nageia nagi (Thunb.) O. Ktze, and Spathodea campanulata Breauv., The wilted and died trees were cut down and their residual roots were removed by excavators. Tree Surgery treatment was applied ot the preliminarily infected and still alive mahogany trees. The infected root tissued were excised, and treated the wound with Oxine copper (500X). Fungicides Triadimefon (500X) and Qxine copper (500X) were applied into the soil arounding the diseased trees. Tree brown root rot disease was a fast wilted disease, and infected trees survived only for 3 months from falling leaves to death on general observation and documents. The mahogany trees have survived for more than 16 months after tree surgery and chemical treatment, and grown new twigs and leaves. These diseased trees were gradually restored. |
