-
, (2008/06/13)
A method of controlling Take-All disease of plants by applying a fungicide of the formula STR1 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)p H(2-p) --; or when Q is C, W is selected from --C(R3)p H(2-p), --N(R3)m H(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.

From studies of the kinetics of the reactions of N-tert-butylbenzoazetinone (3a) with diethylamine and with alcohols to give the ring-opened adducts 4, the presence of a trace equilibrium component, the more electrophilic imino ketene 2a, has been inferre
