A compound of formula (I): where A is an ortho-substituted ring selected from a number of specified rings; R1 is halogen, cyano, nitro, C1-4 alkyl, C1-4 haloalkyl, C1-4 alkoxy or C1-4 haloalkoxy or optionally substituted C2-4 alkenyl, optionally substituted C2-4 alkynyl or optionally substituted SO2(C1-4)alkyl (where the optionally substituted moieties may each have up to 3 substituents, each independently selected from halogen and C1-4 alkoxy); R2 is C1-4 alkyl, C1-4 haloalkyl, C1-4 alkoxy(C1-4)alkyl or C1-4 alkylthio(C1-4)alkyl or [optionally substituted aryl](C1-4)alkyl- or [optionally substituted aryl]oxy(C1-4)alkyl-(where the optionally substituted aryl moieties may each have up to 3 substituents, each independently selected from halogen and C1-4 alkoxy); R3 is hydrogen, CH2C≡CR4, CH2CR4═C(H)R4, CH═C═CH2 or COR5 or optionally substituted C1-4 alkyl, optionally substituted C1-4 alkoxy or optionally substituted (C1-4) alkylC(═O)O (where the optionally substituted moieties may each have up to 3 substituents, each independently selected from halogen and C1-4 alkoxy, C1-4 alkyl, C1-2 haloalkoxy, hydroxy, cyano, carboxyl, methoxycarbonyl, ethoxycarbonyl, methylsulfonyl and ethylsulfonyl); each R4 is, independently, hydrogen, halogen, C1-4 alkyl, C1-4 haloalkyl, C1-4 alkoxy or C1-4 alkoxy(C1-4)alkyl; and R5 is hydrogen or optionally substituted C1-6 alkyl, optionally substituted C1-4 alkoxy, optionally substituted C1-4 alkoxy(C1-4)alkyl, optionally substituted C1-4 alkylthio(C1-4)alkyl or optionally substituted aryl (where the optionally substituted moieties may each have up to 3 substituents, each independently selected from halogen, C1-6 alkoxy, C1-6 haloalkoxy, cyano, hydroxy, methoxycarbonyl and ethoxycarbonyl).
