Abstract:
A method of controlling disease in a plant caused by Gaeumannomyces sp. comprising applying to the plant locus a fungicidally effective amount of a fungicide of the formula ##STR3## wherein Z.sub.1 and Z.sub.2 are C and are part of an aromatic ring which is thiophene; andA is --C(X)-amine wherein the amine is an N-bonded heterocyclic compound chosen from the group consisting of pyrrole, pyrazole imidazole, and triazole, each optionally substituted with C.sub.1 -C.sub.6 alkyl groups;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 or Si;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;n is 2;m is 0 or 1;p is 0, 1, or 2;wherein the two R groups are alkenyl groups and are combined to form a fused ring with the thiophene ring which is benzothiophene; wherein the alkenyl groups are optionally substituted with halo, hydroxy, thio, amino, nitro, cyano, formyl, phenyl, C.sub.1 -C.sub.4 alkoxy, alkylcarbonyl, alkylthio, alkylamino, dialkylamino, alkoxycarbonyl, (alkylthio)carbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkylsulfinyl, or alkylsulfonyl;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; or wherein two R.sub.2 groups may be combined to form a cyclo group with Q;R.sub.3 is C.sub.1 -C.sub.4 alkyl;R.sub.4 is C.sub.1 -C.sub.4 alkyl, haloalkyl, alkoxy, alkylthio, alkylamino, or dialkylamino;or an agronomic salt thereof.
