A compound, composition, and method for controlling Take-all disease of plants by applying a fungicide of the formula: ##STR1## wherein Z.sub.1 and Z.sub.2 are carbons of a furan ring; A is selected from the group consisting of --C(X)-amine wherein the amine is substituted with a first and a second amine substituent or with an alkylaminocarbonyl and a hydrogen, --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 may also be selected from --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, or 2; m is 0 or 1; p is 0, 1, or 2; wherein two R.sub.2 groups may be combined to form a cyclo group with Q which is 1-methylcyclopropyl, 1-methylcyclobutyl, 1-methylcyclopentyl, or 1-methylcyclohexyl; provided that B is not trimethylsilyl when A is (diethylamino)carbonyl or (t-butylamino)carbonyl; or an agronomic salt thereof; the first and second amine substituents and R, R.sub.2, R.sub.3, R.sub.4, and R.sub.7 are defined herein.
