Title: Fungicides for the control of take-all disease of plants

Abstract: A method of controlling Take-all disease of plants by applying, preferably to the seed prior to planting, a fungicide of the formula ##STR1## wherein Z.sub.1 and Z.sub.2 are C or N and are part of an aromatic ring selected from benzene, pyridine, thiophene, furan, pyrrole, pyrazole, thiazole, and isothiazole; A is selected from --C(X)-amine, --C(O)--SR.sub.3, --NH--C(X)R.sub.4, and --C(.dbd.NR.sub.3)--XR.sub.7 ; B is --W.sub.m --Q(R.sub.2).sub.3 or selected from o-tolyl, 1-naphthyl, 2-naphthyl, and 9-phenanthryl, each optionally substituted with halogen or R.sub.4 ; Q is C, Si, Ge, or Sn; W is --C(R.sub.3).sub.p H.sub.(2-p) --; or when Q is C, W is selected from --C(R.sub.3).sub.p H.sub.(2-p) --, --N(R.sub.3).sub.m H.sub.(1-m) --, --S(O).sub.p --, and --O--; X is O or S; n is 0, 1, 2, or 3; m is 0 or 1; p is 0, 1, or 2; each R is independently selected from a) halo, formyl, cyano, amino, nitro, thiocyanato, isothiocyanato, trimethylsilyl, and hydroxy; b) C1-C4 alkyl, alkenyl, alkynyl, C3-C6 cycloalkyl, and cycloalkenyl, each optionally substituted with halo, hydroxy, thio, amino, nitro, cyano, formyl, phenyl, C1-C4 alkoxy, alkylcarbonyl, alkylthio, alkylamino, dialkylamino, alkoxycarbonyl, (alkylthio)carbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkylsulfinyl, or alkylsulfonyl; c) phenyl, furyl, thienyl, pyrrolyl, each optionally substituted with halo, formyl, cyano, amino, nitro, C1-C4 alkyl, alkenyl, alkynyl, alkoxy, alkylthio, alkylamino, dialkylamino, haloalkyl, and haloalkenyl; d) C1-C4 alkoxy, alkenoxy, alkynoxy, C3-C6 cycloalkyloxy, cycloalkenyloxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, dialkylamino, alkylcarbonylamino, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkylcarbonyl, alkylcarbonyloxy, alkoxycarbonyl, (alkylthio)carbonyl, phenylcarbonylamino, phenylamino, each optionally substituted with halo; wherein two R groups may be combined to form a fused ring; each R.sub.2 is independently selected from alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl and phenyl, each optionally substituted with R.sub.4 or halogen; and wherein, when Q is C, R.sub.2 may also be selected from halo, alkoxy, alkylthio, alkylamino, and dialkylamino; wherein two R.sub.2 groups may be combined to form a cyclo group with Q; R.sub.3 is C1-C4 alkyl; R.sub.4 is C1-C4 alkyl, haloalkyl, alkoxy, alkylthio, alkylamino, or dialkylamino; and R.sub.7 is C1-C4 alkyl, haloalkyl, or phenyl, optionally substituted with halo, nitro, or R.sub.4 ; or an agronomic salt thereof.
