摘要： 为有效防治水稻纹枯病，延缓病原菌对嘧菌酯抗药性的产生，开展了6种嘧菌酯复配剂对水稻纹枯病的田间药效试验。试验结果表明，20%氟酰胺?嘧菌酯水分散粒剂、75%甲硫?嘧菌酯水分散粒剂、75%戊唑醇?嘧菌酯水分散粒剂和32%丙环唑?嘧菌酯悬浮剂4种复配剂对水稻纹枯病有良好的防治效果，其防效均高于生产上广泛应用的5%井岗霉素水剂，防治效果分别为82.50%~86.68%、73.87%~85.33%、73.20%~84.75%和73.71%~82.63%。

Abstract: In order to control rice sheath blight and delay the onset of azoxystrobin resistance, field efficacy trials of six azoxystrobin mixtures on rice sheath blight was carried out. The results showed that, flutolanil?azoxystrobin 20% WDG, thiophanate-methyl?azoxystrobin 75% WDG, tebuconazole?azoxystrobin 75% WDG and propiconazole?azoxystrobin 32% SC were effective in control of rice sheath blight, as well as the control effect were respectively 82.50%-86.68%, 73.87%-85.33%, 73.20%-84.75% and 73.71%-82.63%, which were higher than those of jinggangmycin 5% AS used in the production widely.
