Compounds of the general formula I or a salt thereof are provided as pesticides against whiteflies, lepidoptera and certain fungi, in which n represents an integer from 0 to 4; m represents an integer 0 or 1; each R independently represents a halogen atom or a nitro, cyano, hydroxyl, alkyl, alkenyl, haloalkyl, haloalkenyl, alkoxy haloalkoxy, haloalkenoxy, amino, alkylamino, dialkylamino, alkoxycarbonyl, carboxyl, alkanoyl alkylthio, alkylsulfinyl, alkylamino, carbamoyl group. , cycloalkyl, aryl, or aralkyl; R1 and R2 each independently represent an optionally substituted alkoxy group or together represent a group = O, = S or = N-OR9, where R9 represent a hydrogen atom or an optionally substituted alkyl group; R3 represents a hydroxyl group, or a group -OL where L is a leaving group, or a group which in vivo is transformed into a group -OL1, where L1 is a leaving group, R7 and R8 independently represent an optionally substituted alkoxy group or together represents a group = O, = So = N-OR9, is as previously defined; wherein R4 and R5 independently represent a halogen atom of an optionally substituted alkyl or alkenyl group, or together with the interadjacent carbon atom represent an optionally substituted cycloalkyl or cycloalkenyl ring; and A represents a straight or branched chain alkyl or alkenyl group which can be optionally substituted, an acyclic carbon chain which is attached to position 3 of the naphthalene ring shown and the -CHR4R5 portion and where A does not include a quaternary carbon atom in that chain; and where the total number of carbon atoms in the longest carbon chain running from portion 3 of the naphthalene ring shown is not more than 8. |
