【摘要】 通过试验，探索出10%叶菌唑SC不同剂量单用或其与430 g/L戊唑醇SC不同剂量复配防治小麦穗期赤霉病、白粉病的防治效果。结论：用10%叶菌唑SC 50～60 mL/667 m~2或10%叶菌唑SC 40～50 mL+430 g/L戊唑醇SC 20～30 mL/667 m~2，对赤霉病防效好，其防效与用40%丙硫·戊唑醇SC 40 mL/667 m~2相当；在小麦白粉病偏重发生情况下，不可单用叶菌唑，而要每667m~2用10%叶菌唑SC 40～50 mL+430 g/L戊唑醇SC 20～30 mL，对白粉病防效较好，其病指防效在83.52%～92.09%之间，与每667 m~2用40%丙硫·戊唑醇SC 40 mL、麦甜组合50+33 mL、45%戊唑·咪鲜胺EW 50 mL防效相当，优于每667 m~2用48%氰烯菌酯·戊唑醇SC 50 mL。所有含有10% 叶菌唑 SC 的 7 个处理的小麦产量均显著高于空白对照。更多还原

【Abstract】 Through experiments, the control effects of 10% carbendazole SC at different doses alone or in combination with430 g/L tebuconazole SC at different doses on wheat head blight and powdery mildew were explored. Conclusion: the control effect of 10% carbendazole SC 50～60 m L/667 m~2or 10% carbendazole SC 40～50 mL+430 g/L tebuconazole SC 20～30 m L/667 m~2 on scab was good, and the control effect was equivalent to that of 40% propionazole and tebuconazole SC 40 m L/667 m~2; In the case that wheat powdery mildew is more serious, it was not allowed to use carbendazole alone, but to use10% carbendazole SC 40～50 m L+ 430 g/L tebuconazole SC 20～30 m L every 667 m~2.The control effect on wheat powdery mildew was better. The disease index control effect was between 83.52% and 92.09%, which was equivalent to that of using 40% propionazole ·tebuconazole SC 40 mL every 667 m~2, 50 + 33m L of maitian combination, and 45% pentazole· prochlorazole EW 50 mL every 667 m~2, and was better than that of using 48% cyanendrin· tebuconazole SC 50 mL every 667 m~2. The wheat yield of all 7 treatments containing 10%carbendazole SC was significantly higher than that of the blank control.更多还原
