中文摘要 | 梅白粉病係由病原菌Podosphaera tridactyla(Wallr.)de Bary所引起,可為害 梅幼嫩枝條、葉片與梅果,是梅樹的重要病害之一。一九九一和一九九二年元月 至四月分別在南投縣信義鄉及水里鄉兩地梅園進行梅白粉病的化學防治試驗。發 現40邁克尼可濕性粉劑、40護矽得乳劑及20.8比芬諾乳劑等三種農藥均可有效防 治梅白粉病的發生。此外,施用這三種藥劑期間,梅葉或梅果並無任何藥害產生。 因此,擬建議推薦給梅農使用。 |
英文摘要 | Powdery mildew on Japanese apricot (Prunus, murne Sieb. et Zucc.). caused hyPodosphaera tridactyla (Wallr.) de Bary is one of the most serious diseases on fruits andleaves of Japanese apricot in Taiwan. In 1991 and 1992, three field experiments were conducted to study the effect of three fungicides on control of powdery mildew of Japaneseapricot (cv. Ch'ing-May), at Hsinyi and Shuili in Nantow County. The experimental resultsshowed that Myclobutanil 40 WP (8000X), Flusilazole 40 EC (8000X), and Pyrifenox 20.8 EC(6000X) were significantly effective to reduce disease severity of powdery mildew on fruitsand leaves of Japanese apricot. In addition, it was also proved that three fungicides did notcause any chemical injury on fruits and leaves of Japanese aprcot during the periods of threefield trials. |
