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 fingicide 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 respectively, --C(O)--SR.sub.3, --NH--C(X)R.sub.4 and --C(.dbd.NR.sub.3)--XR.sub.7 or an alkylaminocarbonyl and a hydrogen; wherein X is O or S;wherein 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;wherein B is --W.sub.m --Q(R.sub.2).sub.3 ;Q is C or Si;W is --C(R.sub.3).sub.p H.sub.(2-p) --, --N(R.sub.3).sub.m H.sub.(1-m)--, --S(O).sub.p --, or --O--;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; alkoxy, alkylthio, alkylamino, and dialkylamino;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; 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 thereof;wherein R is 0, 1, 2, 3 or 4 and each R is independently selected from;a) halo, formyl, cyano, amino, nitro, thiocyanato, isothiocyanato, 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;d) 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.
