| 中文摘要: |
| 小麦叶锈病是威胁我国小麦安全生产的重要病害之一, 近年来其发生程度有逐年加重的趋势。为了筛选有效的化学防治药剂, 对5种杀菌剂进行了田间药效试验。结果表明, 5%烯唑醇微乳剂1 000～2 000倍液、430 g/L戊唑醇悬浮剂3 000～5 000倍液、10%氟硅唑微乳剂1 500倍液、1 750倍液、20%丙环唑微乳剂400～800倍液、2%武夷菌素水剂300倍液、400倍液试验处理防效均高于50%。从增产效果来看, 20%丙环唑微乳剂600倍液的增产率最高, 达到42.33%。5%烯唑醇微乳剂2 000倍液, 430 g/L戊唑醇悬浮剂5 000倍液兼具高防效和高效益(产出/投入), 建议推广使用。 |
| 英文摘要: |
| Wheat leaf rust caused by Puccinia triticina is one of the important epidemic diseases that threaten to wheat safety. In order to select the most effective fungicides, five fungicides were chosen to test the control effect on wheat leaf rust in field plot. The effects of diniconazole 5% ME diluted 1 0002 000 times, 430 g/L tebuconazole SC diluted 3 0005 000 times, 10% flusilazole ME diluted 1 500 and 1 750 times, 20% propiconazole ME diluted 400800 times, 2% wuyiencin AS diluted 300 and 400 times are excellent, with the control efficacy of above 50%. Propiconazole 20% ME diluted 600 times can increase wheat production by up to 42.33%, higher than other treatments. We suggest to apply diniconazole 5% ME diluted 2 000 times and 430 g/L tebuconazole SC diluted 5 000 times on wheat leaf rust control due to their excellent effect and high benefits (output/input). |
