Abstract:
A method of controlling disease in a plant caused by Gaeumannomyces sp. comprising applying to the plant locus a composition comprising 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 furan; andA 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 ;the first amine substituent is selected from the group consisting of C.sub.1 -C.sub.10 straight or branched alkyl, alkenyl, or alkynyl groups or mixtures thereof, optionally substituted with one or more halogen, hydroxy, alkoxy, alkylthio, nitrile, alkylsulfonate, haloalkylsulfonate, phenyl, a 5-membered heteroaryl, C.sub.3 -C.sub.6 cycloalkyl and C.sub.5 -C.sub.6 cycloalkenyl; phenyl optionally substituted with one or more C.sub.1 -C.sub.4 straight or branched alkyl, alkenyl, or alkynyl groups or mixtures thereof, cycloalkyl, cycloalkenyl, haloalkyl, alkoxy and nitro; C.sub.3 -C.sub.6 cycloalkyl, C.sub.5 -C.sub.6 cycloalkenyl, alkoxy, alkenoxy, alkynoxy, dialkylamino, and alkylthio;and the second amine substituent is selected from the group consisting of hydrogen, C.sub.1 -C.sub.6 straight or branched alkyl, alkenyl, or alkynyl groups or mixtures thereof optionally substituted with one or more halogen; hydroxy, alkylcarbonyl, haloalkylcarbonyl, alkoxycarbonyl, and dialkylphosphonyl;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 2;m is 0 or 1;p is 0, 1, or 2;wherein the two R groups are combined to form a ionheterocyclic ring fused to said furan ring which is not benzofuran when A is C(X) amine, B is W.sub.m (Q)(R.sub.2).sub.3, and Q is C or Si, said R groups being selected from the group consisting of C.sub.1 -C.sub.4 alkyl, alkenyl, C.sub.3 -C.sub.6 cycloalkyl and cycloalkenyl, each optionally substituted with hydroxy, thio, phenyl, C.sub.1 -C.sub.4 alkoxy, alkylthio, alkylsulfinyl, or alkylsulfonyl; andeach 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 alkoxy, alkylthio, alkylamino, and dialkylamino;wherein further when Q is C, then two R.sub.2 groups may be combined to form a cycloalkyl 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; andR.sub.7 is C.sub.1 -C.sub.4 alkyl, haloalkyl, or phenyl, optionally substituted with halo, nitro, or R.sub.4 ;provided that B is not trimethylsilyl when A is (diethylamino)carbonyl;or an agronomic salt thereof.
