A fungicidal method which comprises applying to the locus of a plant pathogen a fungicidally effective but non-phytotoxic amount of a compound of the formula (1) <IMAGE> (1) wherein: R1 to R4 are independently H, halo, (C1-C4) alkyl, branched (C3-C4) alkyl, halo (C1-C4) alkyl, (C1-C4) alkoxy, NO2, or HN2, at least two of R1 to R4 being H, or one of R2 to R4 is -NR7-Y-Ar or O-Y-Ar and the rest of R1 to R4 are H; W is N, or CR5; R5 is H, CH3, Cl, O-Y-Ar, or -NR7-Y-Ar; R6 is H, CH3, Cl, or Br; A is -O-Alk or -X-Y-Ar; Alk is a C2-C18 saturated or unsaturated hydrocarbon chain, straight chain or branched, optionally substituted with halo, halo (C1-C4) alkoxy, (C3-C8) cycloalkyl, hydroxy, or acetyl; X is O, NR7, or CR8R9, provided that if one of R2 to R5 is NR7-Y-Ar or O-Y-Ar, then X-Y-Ar is an identical group; R7 is H, (C1-C4) alkyl, or acetyl; R8 and R9 are independently H, (C1-C4) alkyl, halo, or OH, or R8 and R9 combine to form a saturated or unsaturated carbocyclic ring comprising three to seven carbon atoms; Y is an alkylene chain 2 to 8 carbon atoms long that optionally includes an O, S, SO, SO2, or NR7 group, and optionally includes a saturated or unsaturated carbocyclic ring comprising three to seven carbon atoms, and optionally is substituted with (C1-C3) alkyl, (C1-C4) alkenyl, phenyl, (C3-C8) cycloalkyl, hydroxy, halo, or acetyl; and Ar is an aryl group. |
