Fungicidal compounds of formula (I): ##STR1## in which X and Y are independently O or S, and A and R.sup.1 to R.sup.4 have various specified values.

Fungicides

Fungicidal compounds of the formula (I): ##STR1## in which A and B are independently H, fluoro, chloro, bromo, C.sub.1-4 alkyl, C.sub.1-4 alkoxy or halo(C.sub.1-4)alkyl provided that both are not H; D and E are independently H or fluoro; R.sup.1 is H, C.sub.1-4 alkyl or C.sub.1-4 alkoxy; R.sup.2 is CC.sub.1-4 alkyl, C.sub.1-4 alkoxy or optionally substituted phenyl, or R.sup.1 and R.sup.2 together with the nitrogen atom to which they are attached join to form a morpholine, piperidine, pyrrolidine or azetidine ring which is optionally substituted with C.sub.1-4 alkyl; R.sup.3 is H; R.sup.4 is trichloromethyl, C.sub.2-8 alkyl (optionally substituted with halogen, C.sub.1-8 alkoxy or R'S(O) in which R' is C.sub.1-4 alkyl, C.sub.2-4 alkenyl or C.sub.2-4 alkynyl and n is 0, 1 or 2), cyclopropyl (optionally substituted with halogen or C.sub.1-4 alkyl), C.sub.2-8 alkenyl, C.sub.2-8 alkynyl, C.sub.1-8 alkoxy, mono- or di(C.sub.1-4)alkyl- amino or the group, R'ON.dbd.C(CN) in which R' is C.sub.1-4 alkyl, or R.sup.3 and R.sup.4 together with the group C(O)N to which they are attached join to form an azetidin-2-one ring which is optionally substituted with halogen or C.sub.1-4 alkyl; and X and Y are independently oxygen or sulphur.
