落花生蚽f的防治藥劑80﹪Mancozeb W.P.,75﹪Chlorothalonil W.P.及5﹪Hexaconazole F.P.等,與夜盜蟲類及小綠葉蟬的防治藥劑5﹪Cypermethrin E.C.,31.6﹪Plucythrinate E.C.及2.8﹪Bifenthrin E.C.等混合後立即使用,除Hexaconazole與Cypermethrin之混合對夜盜蟲類之防治效果略有影響外,其餘八種混合使用之組合,對蚽f,夜盜蟲類及小綠葉蟬之影響均不顯著,其中以Hexaconazole與Bifenthrin之混合使用效益最佳。Hexaconazole與Plucythrinate混合使用次之。應用時,可減少2~3次防治工資,每公頃以1,500元計算,則可減輕3,000元~4,500元之生產成本。
