中文摘要 | 本試驗目的在阻止銀葉粉蝨蔓延及評估防治效益。調查結果顯示,以花椰菜受害最嚴重,其次為球莖甘藍及甘藍菜。經緊急防治後,後龍地區銀葉粉蝨之危害減少80%,疫情迅速得以控制,不再繼續蔓延。花椰菜銀葉粉蝨緊急防治之效益評估結果,以施藥配合黃色黏板誘殺處理之防治效果最佳,每公頃收益比為281。 |
英文摘要 | The experiment was aimed to evaluate the effect of urgent control on silverleaf whitefly, Bemisia argentifollii from spreading. The silverleaf whitefly mainly damaged on cauliflower, kohlrab and cabbage. Urgent control of silverleaf whitefly by application 2.8 % Bifenthrin E. C., using yellow sticky card and combined of both were tested on cauliflower in Houlung area. A significant decrease of 80 % in silverleaf whitefly damage was obtained in field after assessment of urgent control. The highest net profit ratio of 281 per hectare was obtained from the treatment by application 2.8 % Bifenthrin E. C. in combination with yellow sticky card. |
