| 摘 要： | 采用3%苯醚甲环唑悬浮种衣剂、2.5%咯菌腈悬浮种衣剂、4.8%苯醚·咯菌腈悬浮种衣剂、400g/L萎锈·福美双悬浮种衣剂4种种衣剂对青稞种子进行拌种处理,评价不同种衣剂对青稞条纹病防治效果和对青稞产量的影响。结果表明,不同种衣剂拌种处理对青稞条纹病均有一定抑制作用,其中3%苯醚甲环唑悬浮种衣剂2.0 mL/kg处理的防效达96.43%,1.5 mL/kg处理的小区青稞增产效果最明显,可显著减少条纹病引起的产量损失。说明3%苯醚甲环唑悬浮种衣剂是一种有前途的青稞条纹病抑制剂,可在农业生产实践中进行推广应用。

| Abstract: | In this study, control effects of four seed coatings including 3% difenoconazole FSC, 2.5% fludioxonil FSC, 4.8% difenoconazole·fludioxonil FSC and 400 g/L carboxin·thiram FSC were investigated on barley leaf stripe caused by Drechslera graminea. The results showed that four seed coatings have good control effect on barley leaf stripe. Control efficacy of 3% difenoconazole FSC 2.0 mL/kg reached 96.43%. 3% difenoconazole FSC 1.5 mL/kg significantly reduced yield loss caused by barley leaf stripe. These results indicated that 3% difenoconazole FSC is a promising fungicide for barley leaf stripe and is suitable for wide application in practical disease control. |
