The invention provides a method for the control of arthropod, plant, nematode, helminth or protozoan pests using a 2-phenylimidazole derivative of the formula:
wherein R¹ represents hydrogen, alkyl (optionally substituted by alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, cyano, carboxy, or alkoxycarbonyl), R² and R³, each represents hydrogen, halogen, nitro, carboxy, cyano, alkoxycarbonyl, alkanoyl, or optionally alkyl substituted carbamoyl, or sulphamoyl, or amino (optionally substituted by alkyl, alkoxycarbonyl or alkanoyl) or a group R, RO, RS, RSO or RSO₂ in which R represents alkyl (optionally substituted by halogen), and
Ar represents a group of the formula:
wherein R⁴ and R⁶ each represents halogen or a group R, RO, RS, RSO or RSO₂, and R⁵, R⁷ and R⁸ each represents a substituent as defined for R⁴ and R⁶, or represents hydrogen, hydroxy, carboxy, nitro, cyano, amino, alkylamino (optionally substituted by alkyl, alkoxycarbonyl or alkanoyl), alkoxycarbonyl or alkanoyl or a pesticidally acceptable salt thereof, with the exclusion of compounds in which R² and R³ simultaneously represent hydrogen atoms, compositions for use in the method and novel compounds of formula I.
本发明提供了一种利用式 2-苯基咪唑衍生物防治节肢动物、植物、线虫、蠕虫或原生动物害虫的方法:
其中 R¹ 代表氢、烷基(任选被烷氧基、烷硫基、烷基亚磺酰基、烷基磺酰基、氰基、羧基或烷氧基羰基取代),R² 和 R³ 各自代表氢、卤素、硝基、羧基、氰基、烷氧基羰基、烷酰基、或任选被烷基取代的氨基甲酰基、或氨基磺酰基、或氨基(任选被烷基、烷氧羰基或烷酰基取代)或一个基团 R、RO、RS、RSO 或 RSO₂,其中 R 代表烷基(任选被卤素取代),以及
Ar 代表式中的一个基团:
其中 R⁴ 和 R⁶ 各自代表卤素或一个基团 R、RO、RS、RSO 或 RSO₂,而 R⁵、R⁷ 和 R⁸ 各自代表一个如 R⁴ 和 R⁶ 所定义的取代基,或代表氢、羟基、羧基、硝基、氰基、氨基、烷基氨基(任选被烷基取代)、烷氧基羰基或烷烃基、烷氧基羰基或烷酰基)、烷氧基羰基或烷酰基或其杀虫剂可接受的盐,但不包括 R² 和 R³ 同时代表氢原子的化合物、用于本方法的组合物和式 I 的新型化合物。
