摘要

爲於短期内解決草莓白粉病（Sphaerotheca macularis f. sp. fragariae）防治藥劑不足問題，行政院農業委員會動植物防疫檢疫局鼓勵廠商申請新藥，並同時依新制度之登記藥劑進行延伸使用之相關試驗。在2008年進行新藥劑田間試驗，及2007年至2008年初進行延伸使用範圍藥劑試驗，篩選出25％布瑞莫與50％克收欣2種藥劑稀釋2000倍對草莓白粉病可達57〜58％防治。此外，所推薦藥劑25％布瑞莫及延伸使用藥劑50％克收欣，防治效果不但優於其他藥劑，安全採收期亦僅爲3天，更符合農民作業及觀光採果安全要求。

Owing to the poverty of pesticides against strawberry diseases, the Bureau of Animal and Plant Health Inspection and Quarantine (BAPHIQ) decided to encourage pharmaceutical factories to develop new chemical agents and expand additional planted areas for their trial implementation. The BAPHIQ expected to popularize the usage of these new selected pesticides in strawberry farming to effectively deter the spread of powdery mildew in a short term. After a series of considerate and exhaustive experiments conducted in 2007 and early 2008, the results was shown that the selected two chemical agents, 25% of Bupirimate and 50% of Kresoxim-methyl, as the landmark recommendation. These two recommended pesticides performed better than others because of their high disease-control efficiency, 57~58%, least marker residue and the shortest 3-day pre-harvesting waiting periods. This would fulfill the demands for more effective farming management, higher production, and more stable fruit-edible-safety during the tourist season.
