摘　　要：[目的]明确9%吡唑醚菌酯微囊悬浮剂对水稻稻瘟病的防治效果。[方法]9%吡唑醚菌酯微囊悬浮剂55.56、64.44、73.33 ml/667m^(2)三个浓度处理,以75%肟菌·戊唑醇水分散粒剂为对照药剂,采用田间茎叶喷雾的方法,评价杀菌剂的防治效果。[结果]9%吡唑醚菌酯微囊悬浮剂对水稻稻瘟病有较好的防治效果,且持效期长,对水稻叶瘟和穗颈瘟的最高防效分别为83.98%和80.26%,显著优于对照药剂,对水稻具有增产效果,增产率为4.17%~10.48%。[结论]9%吡唑醚菌酯微囊悬浮剂可有效防治水稻稻瘟病,最适使用剂量为64.44~73.33 ml/667 m^(2)。[Aims]The aim is to further confirm the controlling efficiency of the Pyraclostrobin 9%CS against rice blast and to be applied widely to production practice.[Methods]Three spraying dosages 55.56 ml/667 m2,64.44 ml/667 m2 and 73.33 ml/667 m2 of Pyraclostrobin 9%CS agent were used in the test,trifloxystrobin and tebuconazole 75%wg were used as contrasts.While field trial was also conducted to evaluate the control efficacy.[Results]The result indicated that Pyraclostrobin 9%CS had better control effect on rice blast,the left blast and the neck blast control effect could reach to 83.98%and 80.26%.The effect was higher than the control.The yield was increased by 4.17%-10.48%than the control.[Conclusions]The Pyraclostrobin 9%CS was effective in control of the rice blast.The recommended concentration is 64.44 ml/667 m2-73.33 ml/667 m^(2).
