摘　　要：对具有高效、低毒、广谱性的新型杀菌剂25%嘧菌酯悬浮剂,对香蕉尾孢菌叶斑病的防治与应用技术进行探讨。2004～2005年试验结果表明,25%嘧菌酯悬浮剂防治香蕉尾孢菌叶斑病效果优良,该药剂833倍的防治效果分别达到85.39%和85.18%,显著优于对照药剂25%丙环唑(敌力脱)乳油1500倍的防效。25%嘧菌酯悬浮剂使用上推荐在发病前或发病初期开始施药,施药浓度为1250～833倍,每隔10 d喷药1次,连喷3次,最好能与其他类型的杀菌剂混用或交替使用。The application technology of Azoxystrobin 25% SC, which is a new type of fungicide has highly-efficient, low toxicity, and broad-spectrum, against Cercosproa musae was assessed in the field. The results showed that Azoxystrobin 25% SC had high effect against Cercosproa musae, during 2004 to 2005, the result of tests showed that Azoxystrobin 25% SC using 1：833 gave a control effect of 85.39% and 85.18% against Cercosproa musae, and it was much better than Propiconazole（Tilt）25% EC （1：1 500）. Sprayed prior to the onset or early onset of the disease using 1：1 250 to 1：833 every 10 days, used continuously for 3 times, and at the same time mixed with other types of fungicides or used interchangeably.
