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 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 ;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 dialkyl-phosphonyl;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 0 or S;n is 0, 1, 2 or 3;m is 0 or 1;p is 0, 1, or 2;each R.sub.2 is independently selected from alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl and phenyl, each optionally substituted with R.sub.4 or halogen; andwherein, when Q is C, R.sub.2 is selected from the group consisting of alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl alkoxy, alkyloxy, alkylthio, alkylamino, dialkylamino and phenyl, each optionally substituted with R.sub.4 or halogen; or,wherein two R.sub.2 groups as defined above are 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; andR.sub.7 is C.sub.1 -C.sub.4 alkyl, haloalkyl, or phenyl, optionally substituted with halo, nitro, or R.sub.4 ;or an agronomic salt forming cation;R is 0, 1, 2 or 3 and each R is independently selected froma) formyl, amino, trimethylsilyl, and hydroxy;b) C.sub.1 -C.sub.4 alkyl, alkenyl, alkynyl, C.sub.3 -C.sub.6 cycloalkyl, and cycloalkenyl, each 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, alkylsufinyl, or alkylsulfonyl;c) phenyl, furyl, thienyl, pyrrolyl, each optionally substituted with halo, formyl, cyano, amino, nitro, C.sub.1 -C.sub.4 alkyl, alkenyl, alkynyl, alkoxy, alkylthio, alkylamino, dialkylamino, haloalkyl, and haloalkenyl; ord) C.sub.1 -C.sub.4 alkoxy, alkenoxy, alkynoxy, C.sub.3 -C.sub.6 cycloalkyloxy, cycloalkenyloxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, dialkylamino, alkylcarbonylamino, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkylcarbonyl, alkylcarbonyloxy, alkoxycarbonyl, (alkylthio)carbonyl, phenylcarbonylamino, phenylamino, each optionally substituted with halo; andwherein two R groups optionally combine to form a fused benzene ring with the pyrrole ring.
