Abstract

The invention provides fungicidal compounds of formula (I) and salts thereof wherein: R1 is alkyl, alkenyl, alkynyl, carbocyclyl or heterocyclyl, each of which may be substituted, or hydrogen; R2 and R3, which may be the same or different, are any group defined for R1; cyano; acyl; —ORa or —SRa, where Ra is alkyl, alkenyl, alkynyl, carbocyclyl or heterocyclyl, each of which may be substituted; or R2 and R3, or R2 and R1, together with their interconnecting atoms may form a ring, which may be substituted; R4 is alkyl, alkenyl, alkynyl, carbocyclyl or heterocyclyl, each of which may be substituted; hydroxy; mercapto; azido; nitro; halogen; cyano; acyl; optionally substituted amino; cyanato; thiocyanato; —SF5; —ORa; —SRa or —Si(Ra)3; m is 0 to 3; when present R5, which may be the same or different to any other R5, is any group defined for R4; R6 is optionally substituted carbo- or heterocylclyl; and A is a defined linking group, or —A—R6 and R5 together with benzene ring M form an optionally substituted fused ring system.
