| 摘 要： | 为了筛选防治小麦纹枯病的高效药剂,对生产上常用的6种药剂进行了示范研究。试验结果表明:药后50 d,6种药剂对小麦纹枯病病指防效在46.08%~93.14%之间。240 g/L噻呋酰胺SC 150 m L/hm2、75%肟菌·戊唑醇WG 150 g/hm2对小麦纹枯病的防效在90%以上,持效期长。20%井冈霉素AF 375 g/hm2的防效为85.95%,该药剂成本较低,可以在小麦纹枯病发生初期与240 g/L噻呋酰胺SC、75%肟菌·戊唑醇WG交替使用。75%戊唑·嘧菌酯WG 150 g/hm2药后30,50 d的病指防效均在70%以上,在纹枯病轻发年份可考虑使用。

| Abstract: | In order to screen out efficient fungicides, six kinds of fungicides were used to control wheat sharp eyespot by demonstration trial. On the 50 th day after spraying, the control effects of the six fungicides were 46.08%-93.14%. Thifluzamide 240 g/L SC and trifloxystrobin ＋ tebuconazole 75% WG had long persistent efficacy period and the control efficacies were more than 90%. The control effect of Jingangmycin 20% AF was 85.95%, it could be used as substitutional fungicide. The control effects of tebuconazole ＋ azoxystrobin 75% WG were above 70% on the 30 th and 50 th day after spraying. |
