摘 要：
[目的]明确42.4%唑醚·氟酰胺SC在推荐使用剂量下防治马铃薯早疫病的效果,为生产上安全应用提供理论依据。[方法]采用"DMRT"法进行方差分析,并用邓肯氏新复极差法检验差异显著性。[结果]3次施药后10 d,42.4%唑醚·氟酰胺SC 112.5、150 g a.i./hm~2对马铃薯早疫病防效为86.33%~90.17%;42.4%唑醚·氟酰胺SC 75 g a.i./hm~2与300 g/L氟唑菌酰胺SC防效相当,高于250 g/L醚菌酯EC和50%啶酰菌胺WG的防效。[结论]42.4%唑醚·氟酰胺SC对马铃薯早疫病具有较好的防治效果,建议发病初期施用,推荐使用剂量为112.5~150 g a.i./hm~2。

摘 要：
[Aims] This study aims to illuminate the effect of fluxapyroxad-pyraclostrobin 42.4% SC at recommended dosage on potato early blight and to provide the basis for security application in yield.[Methods] The data was analyzed by variance "DMRT" method and Duncan-style with new multiple ranges to test the significance of differences.[Results] The results showed that 10 days after three times of applying pesticide,the control effects of fluxapyroxad-pyraclostrobin 42.4% SC at 112.5 and 150 g a.i./ha on potato early blight are ranging from 86.33 to90.17%.The control effect at 75 g a.i./ha is higher than that of pyraclostrobin EC and boscalid 50% WG at 250 g/L,and is equivalent to that of fluxapyroxad SC at 300 g/L.[Conclusions] The potato early blight disease could be effectively controlled by fluxapyroxad-pyraclostrobin 42.4% SC,especially at initial infection stage treated with the recommended dose of 112.5-150 g a.i./ha in the fields.
