摘　　要：引进7种农药对辣椒白粉病进行药效试验。试验结果表明,施药21 d后,5%己唑醇微乳剂持效性长,防效达82.00%,保产效果达33.6%,与25%腈菌唑乳油防效差异达显著水平,与其他农药防效差异达极显著水平。25%三唑酮可湿性粉剂和20%硫磺·三唑酮可湿性粉剂后期防效达到50%以上,生产中可作为搭配农药交替使用。The trial was carried out to study control efficiency of seven introduced pesticides on powdery mildew of pepper. The results showed that, 21 days after applying the pesticides, 5% hexaconazole micro emulsion （ME） possessed longer lasting effect, with yield increasing rate of 33.6% and control efficiency of 82%, and its control efficiency had significant difference with that of 25% myclobutanil emulsifiable concentrate （EC） and had very significant difference with those of other pesticides. Both the control efficiency of 25% triadimefon and 20% sulfur-triadimefon wettable powder （WP） were higher than 50% at later spraying stages, and they could be used alternately in pepper production.
