A fungicidal compound of formula (1): where Het is a 5- or 6-membered heterocyclic ring containing one to three heteroatoms, each independently selected from oxygen, nitrogen and sulphur, the ring being substituted by groups R7, R8 and R9; R1 is hydrogen, optionally substituted (C1- 4)alkylC(=O),optionally substituted (C1-4)alkylC(=O)O, optionally substitute d (C1-4)alkoxy(C1-4)alkyl, optionally substituted allyl, optionally substitute d propargyl or optionally substituted allenyl; R2, R3, R4 and R5 are each, independently, hydrogen, halogen, optionally substituted (C1-4)alkoxy(C1- 4)alkoxy or optionally substituted (C1-4)alkoxy(C1-4)alkyl; R6 is an organic group containing three to thirteen carbon atoms and at least one silicon ato m and, optionally, one to three heteroatoms, each independently selected from oxygen, nitrogen and sulphur, and is optionally substituted by one to four independently selected halogen atoms; R7, R8 and R9 are each, independently, hydrogen, halogen, C1-3alkyl, C1-3haloalkyl, C1-3alkoxy(C1-3)alkyl or cyano, where at least one of R7, R8 and R9 is not hydrogen; and X is O or S; or an N- oxide thereof; and when present, each optional substituent on alkyl moieties , allyl, propargyl and allenyl is, independently, selected.from halogen, hydroxy, cyano, methoxycarbonyl, ethoxycarbonyl, methoxy, ethoxy, methylsulfonyl, ethylsulfonyl, diflouromethoxy, trifluoromethoxy and trifluorothiomethoxy.
