| 中文摘要 | 從玫瑰及蓎菖蒲上採回含有神澤氏葉璊的葉片,選常用之殺璊劑,以 噴霧法處理葉片。試驗結果,玫瑰上神澤氏葉璊在供試14種殺璊劑中,殺璊率 達91.2%以上的藥劑有25%璊離丹(Oxythioquinox)可濕性粉劑500倍、2.8%畢芬 寧(Bifenthrin)乳劑2,000倍、25%新殺璊(Bromopropylate)乳劑500倍、20%西脫 璊(Benzomate)乳劑1,500倍及57%歐璊多(Propargite)乳劑2,000倍等5種藥劑。 次為20%三亞璊(Amitraz)乳劑800倍、80%硫黃(Sulfur)水分散性粒劑500倍、50% 芬佈賜(Fenbutatin-oxide)可濕性粉劑2,000倍,其殺璊率在83.4∼89.6%之間。但 對神澤氏葉璊的卵僅20%西脫璊(Benzomate)乳劑1,500倍及50%芬佈賜 (Fenbutatin-oxide)可濕性粉劑2,000倍及50% Polo可濕性粉劑1,500倍較有效, 其殺卵率在83.8∼92.5%之間;對蓎菖蒲上之神澤氏葉璊成、若璊之殺璊效果, 在8種供試藥劑中以25%璊離丹(Oxythioquinox)可濕性粉劑500倍、2.8%畢芬寧 (Bifenthrin)乳劑1,000倍、57%歐璊多(Propargite)乳劑1,000倍及25%新殺璊 (Bromopropylate)乳劑500倍等4種較優,其殺璊率在93.5∼99.2%之間,效果甚 佳,對卵亦以上述藥劑較佳,唯殺卵率略有下降。從試驗結果顯示,多種殺璊劑 同時對玫瑰及蓎菖蒲上之神澤氏葉璊均有佳效,若能正式推荐,足供花農輪流使 用。 |
| 英文摘要 | Several common miticides were sprayed onto leaves to test their effectiveness against the kanzawa spider mites collected from roses and gladiolus. Five of the 14 miticides tested, i.e., 25% Oxythioquinox W.P. (500-fold), 2.8% Bifenthrin E.C. (2000-fold), 25% Brom- opropylate E.C. (500-fold), 20% Bnzomate E.C. (1500-fold) and 57% Propargite E.C. (2000-fold) produced mortality as high as 91.2% of this spider mite of roses. 20% Amitraz E.C. (800-fold), 80% Sulfur F.G. (500-fold), 50% Fenbutatin-oxide W.P. (2000-fold), and 50% Polo W.P. (1500-fold) also produced 83.4% to 89.6% mortality. However, only 20% Benzomate E.C. (1500- fold), 50% Fenbutatin-oxide W.P. (2000-fold) and 50% Polo W.P (1500-fold) were ovicidal and gave 83.8% to 92.5% mortality. Among the 8 miticides tested, 25% Oxythioquinox W.P. (500-fold), 2.8% Bifenthrin E.C. (1000-fold), 57% Propargite E.C. (1000-fold) and 25% Bromopropylate E.C. (500-fold) gave excellent control (93.5% to 99.2%) of nymphs and adults of Kanzawa spider mites collected from gladiolus. These chemicals also showed good, but somewhat lower, ovicidal activity. These results indicate that many miticides are still effective against Kanzawa spider mites on roses and gladiolus, and if officially recommended, they can be used alternately by the growers. |
