A compound of formula I
where R1 is alkyl, alkenyl or alkynyl, each of which may be optionally substituted by halogen, alkoxy or aryl, -N=CR4R5 or -NR6R7;
R2 is halo, hydroxy, amino, nitro, cyano, carboxy, alkoxycarbonyl or an optionally substituted alkyl, alkoxy, alkylthio, alkylamino, dialkylamino or alkylsulphonyl group;
R3 is -YR9;
R4, R5, R6, R7 and R8 may be the same or different and are hydrogen, aryl or an optionally substituted alkyl, alkenyl or alkynyl group
R9 has the same meaning as R8 or is acyl;
X and Y are O, S or NR9;
and when R1 is -N=CR4R5 or -NR6R7, R3 can also be hydrogen. The compounds have valuable fungicidal activity, especially against rice blast.
