摘  要:
[目的]明确42.4%唑醚·氟酰胺悬浮剂对桑果菌核病的田间防治效果,为生产上应用提供理论依据。[方法]以70%甲基硫菌灵可湿性粉剂为对照药剂,采用田间小区试验,在浙江省杭州市富阳区、桐庐县、临安区3地进行了田间药效试验。[结果]42.4%唑醚·氟酰胺悬浮剂对桑果肥大型菌核病和小粒型菌核病均有很好的防治效果,106~424 mg a.i./kg范围内防效达到89.66%~98.58%,其防效显著优于70%甲基硫菌灵可湿性粉剂。[结论]42.4%唑醚·氟酰胺悬浮剂对桑果菌核病具有良好的防治效果,对桑树叶片和植株未出现药害。

摘  要:
[Aims] This study aims to determine the field control effect of pyraclostrobin and fluxapyroxad 42.4% SC on mulberry fruit sclerotiniose. [Methods] Taking thiophanate-methyl 70% WP as a control agent, the plot experiment was carried out in Tonglu, Fuyang and Lin′ an of Zhejiang Province. [Results] The control effect of pyraclostrobin and fluxapyroxad 42.4% SC applied at the doses of 106-424 mg a.i./kg against mulberry fruit sclerotiniose was89.66-98.58%, which was better than that of thiophanate-methyl 70% WP. [Conclusions] Pyraclostrobin and fluxapyroxad 42.4% SC had good control effect on mulberry fruit sclerotiniose and was safe to mulberry plants.
