The invention provides a method for the control of arthropod, plant nematode, helminth or protozoan pests using a 2-phenylimidazole derivative of the formula: ##STR1## wherein R.sup.1 represents hydrogen, alkyl (optionally substituted by alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, cyano, carboxy or alkoxycarbonyl), R.sup.2 and R.sup.3, 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 RSO.sub.2 in which R represents alkyl (optionally substituted by halogen), and Ar represents a group of the formula: ##STR2## wherein R.sup.4 and R.sup.6 each represents halogen or a group R, RO, RS, RSO or RSO.sub.2, and R.sup.5, R.sup.7 and R.sup.8 each represents a substituent as defined for R.sup.4 and R.sup.6, 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 R.sup.2 and R.sup.3 simultaneously represent hydrogen atoms, compositions for use in the method and novel compounds of formula I.
本发明提供了一种使用2-苯基咪唑衍生物的方法来控制节肢动物、植物线虫、蠕虫或原生动物害虫,其中所述2-苯基咪唑衍生物的结构式为:##STR1## 其中R.sup.1代表氢、烷基(可选地被烷氧基、烷基硫醇基、烷基亚磺酰基、烷基亚磺酸基、氰基、羧基或烷氧羰基取代)、R.sup.2和R.sup.3各自代表氢、卤素、硝基、羧基、氰基、烷氧羰基、脂肪酰基或可选地被烷基取代的氨基甲酰基或磺酰基,或者是氨基(可选地被烷基、烷氧羰基或脂肪酰基取代)或R、RO、RS、RSO或RSO.sub.2基团,其中R代表烷基(可选地被卤素取代),Ar代表下列结构式的基团:##STR2## 其中R.sup.4和R.sup.6各自代表卤素或R、RO、RS、RSO或RSO.sub.2基团,而R.sup.5、R.sup.7和R.sup.8各自代表与R.sup.4和R.sup.6的定义相同的取代基,或代表氢、羟基、羧基、硝基、氰基、氨基、烷基氨基(可选地被烷基、烷氧羰基或脂肪酰基取代)、烷氧羰基或脂肪酰基,或其农药可接受的盐,但不包括R.sup.2和R.sup.3同时代表氢原子的化合物,以及用于该方法的组合物和公式I的新化合物。
