摘要： 通过田间药效试验，结果表明，已唑醇3000倍、4000倍、5000倍三个浓度处理对桃褐斑病的防效均高于对照药剂代森锰锌处理，且差异性显著；已唑醇3000倍和4000倍处理防效均在90%以上，二者之间无差异显著性，但与已唑醇5000倍处理间在5%水平上存在显著性差异；试验结果还显示250 g/L己唑醇悬浮剂不仅对桃褐斑病防治效果好，不污染果面，而且安全性好，可在果树花期、幼果期使用，增强叶片的光合作用，是目前防治桃褐斑病的理想药剂。

Abstract: A field effect experiment on the Peach Brown Spot (PBS) was conducted. Its results show that the effects of 250 g/L Hexaconazole SC of 3000 times, 4000 times, and 5000 times were higher than Mancozeb with significant difference. Hexaconazole Suspension of 3000 times and 4000 times were higher than 90% in prevention effect with no significant difference. The results also showed that Hexaconazole SC had good effect in preventing peach from PBS, and could be safely used in florescence and infant fruiting period with no pollution peach fruit surface. In all Hexaconazole SC was an ideal pharmacy of controlling PBS by enhancing peach leaf photosynthesis.
