- Pesticidal method using 2-phenylimidazole derivatives
-
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 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: STR2 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.
