Abstract
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 PA0 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 …
