| 中文摘要: |
| 为明确不同杀菌剂对小麦纹枯病、赤霉病的防治效果, 在大田条件下以‘开麦21’为试验材料研究了12种杀菌剂对小麦纹枯病、11种杀菌剂对赤霉病的防治效果及对小麦产量的影响。结果表明:30%己唑醇悬浮剂76.5 g/hm2、75%肟菌·戊唑醇水分散粒剂168.75 g/hm2处理对小麦纹枯病的防效较好, 拔节期病指防效(乳熟期枯白穗防效)分别为62.77%(56.21%)和60.58%(53.45%), 小麦产量较对照分别增加27.65%和21.30%; 48%氰烯·戊唑醇悬浮剂432 g/hm2、25%氰烯菌酯悬浮剂750 g/hm2处理对小麦赤霉病的防效较好, 病指防效(病穗防效)分别为70.78%(56.57%)和68.84%(46.86%), 小麦产量较对照分别增加25.44%和24.40%。综合分析, 以上药剂可做田间大面积推广应用。 |

| In order to clear the control effects of different fungicides against wheat sharp eyespot and wheat scab, wheat ‘Kaimai 21’ was used as experimental material to compare disease control effects of 12 fungicides against wheat sharp eyespot and 11 fungicides against wheat scab in the field and their effect on wheat yield. The results showed that 30% hexaconazole SC 76.5 g/hm2 and 75% trifloxystrobin·tebuconazole WG 168.75 g/hm2 had better control effects against wheat sharp eyespot. The disease index control effects at jointing stage (the withered white wheat ear control effects at milk stage) were 62.77% (56.21%) and 60.58% (53.45%), respectively. The wheat yield increased by 27.65% and 21.30%, respectively, compared with the control group. 48% phenamacril·tebuconazole SC 432 g/hm2 and 25% phenamacril SC 750 g/hm2 had better control effects against wheat scab. The disease index control effects (the diseased ears control effects) were 70.78% (56.57%) and 68.84% (46.86%), respectively. The wheat yield increased by 25.44% and 24.40%, respectively, compared with the control group. By comprehensive analysis, these fungicides were recommended in wheat production. |
