A method of controlling Take-All disease of plants by applying a fungicide of the formula <IMAGE> wherein Z1 and Z2 are C and are part of an aromatic ring which is benzothiophene; and A is selected from -C(X)-amine wherein the amine is an unsubstituted, monosubstituted or disubstituted amino radical, -C(O)-SR3, -NH-C(X)R4, and -C(=NR3)-XR7; B is -Wm-Q(R2)3 or selected from O-tolyl, 1-naphthyl, 2-naphthyl, and 9-phenanthryl, each optionally substituted with halogen or R4; Q is C, Si, Ge, or Sn; W is -C(R3)pH(2-p)-; or when Q is C, W is selected from -C(R3)pH(2-p), -N(R3)mH(1-m)-, -S(O)p-, and -O-; X is 0 or S; n is 0, 1, 2, or 3; m is 0 or 1; p is 0, 1, or 2; each R and R2 is independently defined herein; R3 is C1-C4 alkyl; R4 is C1-C4 alkyl, haloalkyl, alkoxy, alkylthio, alkylamino, or dialkylamino; and R7 is C1-C4 alkyl, haloalkyl, or phenyl, optionally substituted with halo, nitro, or R4; or an agronomic salt thereof. |
