摘要

落花生銹病的防治藥劑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，對銹病，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。

Fungicides, 80% Mancozeb W. P., 75% Chlorothalonil W. P. and 5% Hexaconazole F. P., to control rust and insecticides, 5% Cypermethrin E. C., 31.6% Plucythrinate E. C. and 2.8% Bifenthrin E. C., to control smaller green leaf hopper and army worms was mixed right before spraying or sprayed separately. Except the mixture of Hexaconazole and Cypermethrin had less efficiency to control for army worms, the other 8 combinoions had no influence of control for rust, army worms and smaller green leafhopper. Mixture of Hexaconazole and Bifenthrin got the best results and income.In application, it will save 2-3 times of spraying wage, which costs NT$1,500 dollars per hectare. Thus it will save $3,000~4,500 N. T. dollars per hectare.
