An N-2-(hetero)arylethylcarboxamide derivative represented by the formula (I)
wherein R1 and R2 are each independently a hydrogen atom etc., R3 and R4 are each independently a hydrogen atom etc., each Y is independently a halogen atom; a (C1-C6)alkyl group optionally substituted by halogen atom(s) etc., n is an integer of 1 to 5, A is a specific substituted cyclic group, E is C-H; C-Y (Y is as defined above); or a nitrogen atom, a salt thereof, and a pest controlling agent containing the derivative or salt as an active ingredient show superior performance as compared to the prior art technique, and are useful particularly as plant disease controlling agents or nematocides having a broad control spectrum at a low dose.
由式 (I) 代表的 N-2-(杂)芳基乙基甲酰胺衍生物
其中 R1 和 R2 各自独立地为氢原子等,R3 和 R4 各自独立地为氢原子等,Y 各自独立地为卤素原子、任选被卤素原子等取代的(C1-C6)烷基、n 是 1 至 5 的整数,A 是特定取代的环状基团,E 是 C-H;C-Y(Y 如上文所定义);或氮原子,其盐和含有该衍生物或盐作为活性成分的害虫防治剂与现有技术相比表现出更优越的性能,尤其可用作植物病害防治剂或杀线虫剂,具有低剂量、广谱防治的特点。
