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) ##STR1## wherein: R.sup.1 to R.sup.4 are independently H, halo, (C.sub.1 -C.sub.4) alkyl, branched (C.sub.3 -C.sub.4) alkyl, halo (C.sub.1 -C.sub.4) alkyl, (C.sub.1 -C.sub.4) alkoxy, NO.sub.2, or HN.sub.2, at least two of R.sup.1 to R.sup.4 being H, or one of R.sup.2 to R.sup.4 is --NR.sup.7 --Y--Ar or O--Y--Ar and the rest of R.sup.1 to R.sup.4 are H; W is N, or CR.sup.5 ; R.sup.5 is H, CH.sub.3, Cl, O--Y--Ar, or --NR.sup.7 --Y--Ar; R.sup.6 is H, CH.sub.3, Cl, or Br; A is --O--Alk or --X--Y--Ar; Alk is a C.sub.2 -C.sub.18 saturated or unsaturated hydrocarbon chain, straight chain or branched, optionally substituted with halo, halo (C.sub.1 -C.sub.4) alkoxy, (C.sub.3 -C.sub.8) cycloalkyl, hydroxy, or acetyl; X is O, NR.sup.7, or CR.sup.8 R.sup.9, provided that if one of R.sup.2 to R.sup.5 is NR.sup.7 --Y--Ar or O--Y--Ar, then X--Y--Ar is an identical group; R.sup.7 is H, (C.sub.1 -C.sub.4) alkyl, or acetyl; R.sup.8 and R.sup.9 are independently H, (C.sub.1 -C.sub.4) alkyl, halo, or OH, or R.sup.8 and R.sup.9 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, SO.sub.2, or NR.sup.7 group, and optionally includes a saturated or unsaturated carbocyclic ring comprising three to seven carbon atoms, and optionally is substituted with (C.sub.1 -C.sub.3) alkyl, (C.sub.1 -C.sub.4) alkenyl, phenyl, (C.sub.3 -C.sub.8) cycloalkyl, hydroxy, halo, or acetyl; and Ar is an aryl group.
