摘　　要：对金力士加柔水通对辣椒白粉病进行了防治试验。结果表明：药后5d和10d，25％金力士乳油＋柔水通1500倍液对辣椒白粉病防效分别为74.459／6和83.65％，与25％金力士乳油＋柔水通1000倍液的防效（74.08％和82.54％）相当，高于25％金力士乳油＋柔水通3000倍液的防效（分别为66.8％和73.12％）。加入柔水通的处理防效均高于单纯使用25％金力士乳油的防效（分别为63.93％和68.54％），表明在喷雾用水中加入一定量的柔水通可提高金力士对辣椒白粉的防治效果，用量以1000-1500倍液为宜。Field experiments were conducted to determine the effects of Jinlishi adding Roushuitong （BOISOFT） against pepper powdery mildew. The results showed that the control efficiencies of 5 days and 10 days after treatment using 25% Jinlishi （Propiconazole） EC added Roushuitong（BOISOFT） 1500 times against pepper powdery mildew was 74.45% and 83.65%, respectively. And those were equal to thai of 25% Jinlishi（Propiconazole） EC added Roushuitong（BOISOFT） 1000 times（74.08% and 82.54%）, but better than that of 25% Jinlishi（Propiconazole） EC added Roushuitong （BOISOFT） 3000 times（66.80% and 73.12%）. The control efficiency of adding Roushuitong（BOISOFT） were all higher than that of using 25% Jinlishi（Propiconazole）EC only, it implied that adding proper amount of Roushuitong（BOISOFT） to the spraying water could enhance the control efficiency of Jinlishi against pepper powdery mildew.
