摘要

銷日菊花害蟲檢疫問題可以田間花蕾套袋與切花後藥液浸漬莖葉配合應用而獲得解決。田間自花蕾尚未展開時即予以套袋，可杜絕爲害花部害蟲之發生，並減少田間之施用殺蟲藥劑。切花後浸漬切花之莖葉於殺蟲劑與殺蟎劑之混合稀釋液中，可毒殺附著莖葉上之害蟲及害蟎。此種方式處理之菊花無害蟲存在，且任何品種之菊花均可應用。以往白色花浸藥後因污斑而品質降低之現象將可消除。經處理之切花其保鮮期不受影響。

並列摘要

Transparent PE bags (13×17cm) fully covered with holes (din. 0.2-0.5 mm) were used to protect chrysanthemum blooms in field. Young buds were covered and protected with these bags prior to the appearance of any petals, and these buds growing and blooming inside the bags. The change of attack of insect pests was hence significantly eliminated or avoided depending on the size of holes on bags.
After cutting, dipping the stem below the flower head in diluted insecticides and acaricides would kill the aphids and mites stayed on leaves. Acricide 25 WP and Decis 2.8 EC were the most effective chemicals screened in this experiment.
The application of the proper protection bags on buds and the improvement of dipping method offered insect-free cut flowers and eliminated the amount of insecticides used in field. Blooms, especially those in white color were not polluted with insecticides. And the keeping period of cut flowers was not influenced.
