Abstract

Abstract Combating fungi with dicarboxylic acid mono-aryl-hydrazides of the formula ##STR1## in which R 1 and R 2 each independently is hydrogen, halogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, C 1 -C 4 alkylmercapto, trihalogenomethyl, trihalogenomethoxy, trihalogenomethylmercapto or nitro, X is an alkylene, alkenylene, cycloalkylene, cycloalkenylene, cycloalkadienylene or phenylene radical, and M is hydrogen or one equivalent of a metal, or a salt thereof.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 94 words
A method of combating fungi which comprises applying to the fungi, or to a habitat thereof, a fungicidally effective amount of at least one dicarboxylic acid monoarylhydrazide, or a salt thereof, of the formula ##STR15## in which R 1 and R 2 each independently is hydrogen, halogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, C 1 -C 4 alkylmercapto, trihalogenomethyl, trihalogenomethoxy, trihalogenomethylmercapto or nitro, X is an alkylene, alkenylene, cycloalkylene, cycloalkenylene, cycloalkadienylene or phenylene radical, and M is hydrogen or one equivalent of an alkali or alkaline earth metal or ammonium.
Claim 2
Independent Claim 94 words
A method of combating fungi which comprises applying to the fungi, or to a habitat thereof, a fungicidally effective amount of at least one dicarboxylic acid monoarylhydrazide, or a salt thereof, of the formula ##STR15## in which R 1 and R 2 each independently is hydrogen, halogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, C 1 -C 4 alkylmercapto, trihalogenomethyl, trihalogenomethoxy, trihalogenomethylmercapto or nitro, X is an alkylene, alkenylene, cycloalkylene, cycloalkenylene, cycloalkadienylene or phenylene radical, and M is hydrogen or one equivalent of an alkali or alkaline earth metal or ammonium.
Claim 3
Dependent Claim 56 words
The method according to claim 1, in which R 1 and R 2 each independently is hydrogen, chlorine, methyl, methoxy, methylmercapto, trifluoromethyl, trifluoromethoxy, trifluoromethylmercapto or nitro, and X is an alkylene or alkenylene radical with 2 to 4 carbon atoms, a cycloalkylene, cycloalkenylene or cycloalkadienylene radical with 4 to 7 carbon atoms or a phenylene radical.
Claim 4
Dependent Claim 19 words
The method according to claim 1, wherein such dicarboxylic acid mono-arylhydrazide is maleic acid mono(3-chloro-4-trifluoromethyl-phenyl)-hydrazide of the formula ##STR16##
Claim 5
Dependent Claim 19 words
The method according to claim 1, wherein such dicarboxylic acid mono-arylhydrazide is maleic acid mono(3-chloro-phenyl)-hydrazide of the formula ##STR17##
Claim 6
Dependent Claim 19 words
The method according to claim 1, wherein such dicarboxylic acid mono-arylhydrazide is maleic acid mono(3-trifluoromethyl-phenyl)-hydrazide of the formula ##STR18##
Claim 7
Dependent Claim 19 words
The method according to claim 1, wherein such dicarboxylic acid mono-arylhydrazide is maleic acid mono(4-choro-3-trifluoromethyl-phenyl)-hydrazide of the formula ##STR19##
Claim 8
Dependent Claim 19 words
The method according to claim 1, wherein such dicarboxylic acid mono-arylhydrazide is 1,2-cyclohexene-4-dicarboxylic acid mono-(3-chloro-4-trifluoromethyl-phenyl)-hydrazide of the formula ##STR20##
