目的]筛选水稻纹枯病的防治药剂.方法]研究了不同厂家生产的噻呋酰胺单剂与复配制剂,以及23％醚菌·氟环唑、30％苯甲,丙环唑等药剂防治水稻纹枯病效果.结果]药后10 d,23％醚菌·氟环唑SC600ml/hm2、24％噻呋酰胺SC 300 ml/hm2（进口）、30％苯甲·丙环唑EC 450 ml/hm2 、40％噻呋酰胺WDG 270 g/hm2、24％噻呋酰胺EC 300 ml/hm2（国产）、40％戊唑·噻唑锌EC 1 050ml/hm2、27.8％噻呋·己唑醇EC 300 ml/hm2 7个处理的校正防效分别为85.47％、85.69％、85.39％、90.74％、85.44％、85.29％和87.78％,10％丙硫·多菌灵SC 750 ml/hm2和6％丙硫·多菌灵SC 1 350 ml/hm2的校正防效分别为57.91％和70.61％;药后20d,各处理防效进一步提高.结论]噻呋酰胺制剂与23％醚菌·氟环唑、30％苯甲·丙环唑、40％戊唑·噻唑锌都可作为防治水稻纹枯病的推荐药剂.

Control Effects of Several Preparations Associated with Trifluzamide against Rice Sheath Blight Disease

Objective]The aim was to screen out efficient agents for controlling rice sheath blight disease.Method]Single agent and compound preparations of Trifluzamide from deferent manufacturers were tested to comfirm field efficacy to control rice sheath blight disease,comparing with 23％ kresoxim methyl · epoxiconazole and 30％ difenoconazole · propiconazole.Result]Ten days after spraying,seven treatments＇ s correction control effects of 23％ kresoxim methyl · epoxiconazole SC 600 ml/hm2,24％ trifluzamide SC 300 ml/hm2 （imported）,30％ difenoconazole · propiconazole EC 450 ml/hm2,40％ trifluzamide WDG 270 g,/hm2,24％ trifluzamide EC 300 ml/hm2 （domestic）,40％ tebuconazole · zinc thiazole EC 1 050 ml/hm2,27.8％ trifluzamide · hexaconazole EC 300 ml/hm2 were 85.47％,85.69％,85.39％,90.74％,85.44％,85.29％ and 87.78％ respectively; the correction control effects of 10％ albendazole · carbendazim SC 750 ml/hm2 and 6％ albendazole · carbendazim SC 1 350 ml/hm2 were 57.91％ and 70.61％ respectively.Twenty days after spraying,the control effect of each treatment was risen.Conclusion]Trifluzamide and its compound preparations and 23％ kresoxim methyl · epoxiconazole,30％ difenoconazole · propiconazole,40％ tebuconazole · zinc thiazole all can be recommendated as the pesticides to control rice sheath blight disease.
