[目的]白粉病是影响辣椒正常生长的重要病害,严重影响辣椒的产量和品质。化学防治是控制辣椒白粉病的重要措施,多种药剂,如三唑酮、苯醚甲环唑、氟硅唑等均可用于该病害的防治。[结果]田间小区试验结果一致表明:20%烯肟菌胺.戊唑醇悬浮剂对辣椒白粉病具有优异的防治效果,100~200 mg/L处理剂量,施药2~3次,对辣椒白粉病的防治效果在85%以上,优于醚菌酯和三唑酮。在试验剂量下,对供试作物辣椒安全。[结论]20%烯肟菌胺.戊唑醇悬浮剂可用于田间辣椒白粉病的防治,具备较好的防治效果和安全性。
[Objective] Powdery mildew is an important disease that affects the normal growth of pepper and seriously affects the yield and quality of pepper. Chemical control is an important measure to control pepper powdery mildew. A variety of agents, such as triadimefon, difenoconazole and flusilazole, can be used for the prevention and control of this disease. [Result] The test results of field plot consistently showed that 20% propoxypyr-tebuconazole SC had excellent control effect on pepper powdery mildew, 100 ~ 200 mg / L treatment dosage and 2 to 3 times spraying. Powdery mildew control effect in more than 85%, better than kresoxim-methyl and triadimefon. In the test dose, the pepper for the test crop safety. [Conclusion] The 20% thiamethoxam and tebuconazole suspending agent could be used for the prevention and control of pepper powdery mildew in the field with good control and safety.
