A compound of formula (I)
wherein R¹, R², R⁴ and R⁵ are independently selected from hydrogen, halogen, lower alkyl optionally substituted by halogen, lower alkoxy optionally substituted by halogen and lower alkenyl optionally substituted by halogen;
R³ is halogen, amino, mono- or di(lower alkyl)-amino, lower alkyl substituted by halogen, lower alkoxy optionally substituted by halogen and lower alkenyl optionally substituted by halogen provided that R³ is not monochloro or monobromo-methyl;
R⁶ is oxygen or sulphur;
R⁷ and R¹⁰ are independently selected from hydrogen, halogen, lower alkyl optionally substituted by halogen, lower alkoxy optionally substituted by halogen, and lower thioalkoxy optionally substituted by halogen; and
R⁸ is hydrogen, halogen, optionally substituted lower alkyl, optionally substituted lower alkoxy, optionally substituted lower thioalkoxy, cyano, nitro, optionally substituted oximino, optionally substituted lower alkenyl, optionally substituted aryloxy, optionally substituted amino or S(O)nR¹¹ wherein n is 0, 1 or 2 and R¹¹ is optionally substituted lower alkyl;
R⁹ is hydrogen, or lower alkyl optionally substituted by halogen, lower alkenyl optionally substituted by halogen or C0₂R¹² wherein R¹² is lower alkyl optionally substituted by halogen; provided that R¹, R², R³, R⁴ and R⁵ are not all hydrogen: and further provided that when R³ is trifluoromethyl and R¹ and R⁵ are halogen, R² and R⁴ are not both hydrogen, or R⁷, R⁸, R⁹ and R¹⁰ do not comprise from one to four halogen or trihalomethyl substitutents.
