Abstract: This invention embodies compositions comprising herbicidally effective compounds corresponding to the formula ##STR1## in which R.sub.1 and R.sub.2 are independently methyl or ethyl,X is H, methyl, chlorine, bromine, fluorine;Y is chlorine, bromine, fluorine; andn is 0, 1 or 2and a non-phytotoxic antidotally effective amount of an antidote therefor selected from the group of amides of haloalkanoic acids, including oxazolidines and thiazolidines, aromatic oxime derivatives, thiazole carboxylic acids and derivatives, substituted phenylpyrimidines, 2-(dichloroacetyl)-2-methyl-1,3-dioxolane and 2-(dichloromethyl)-2-thiazoline.

Abstract: A method of selectively controlling undesirable vegetation in corn by applying an herbicidally effective amount of 2-(2'-nitro-4'-trifluoromethylbenzoyl)- 1,3-cyclohexanedione to the locus of such vegetation.

Abstract: 4-substituted pyridyl-3-carbinols of the formula ##STR1## wherein R is hydrogen, or an acyl, alkyl or carbamyl group exhibit desirable preemergent and postemergent herbicidal activity. Also disclosed are herbicidal compositions comprising such compounds and methods of controlling undesirable vegetation employing such compounds. The compounds wherein AR is hydroxyl serve as useful intermediates for the production of the alpha-benzyl substituted compounds as well as exhibiting herbicidal activity.

Abstract: This invention embodies compositions comprising herbicidally effective compounds corresponding to the formula ##STR1## in which R.sub.1 and R.sub.2 are independently methyl or ethyl,X is H, methyl, chlorine, bromine, fluorine;Y is chlorine, bromine, fluorine; andn is 0, 1 or 2and a non-phytotoxic antidotally effective amount of an antidote therefor selected from the group of amides of haloalkanoic acids, including oxazolidines and thiazolidines, aromatic oxime derivatives, thiazole carboxylic acids and derivatives, substituted phenylpyrimidines, 2-(dichloroacetyl)-2-methyl-1,3-dioxolane and 2-(dichloromethyl)-2-thiazoline.

Abstract: This invention embodies compositions comprising herbicidally effective compounds corresponding to the formula ##STR1## in which R.sub.1 and R.sub.2 are independently methyl or ethyl,X is H methyl, chlorine, bromine, fluorine;Y is chlorine, bromine, fluorine: andn is 0, 1, or 2 and a non-phytotoxic antidotally effective amount of an antidote therefore selected from the group of amides of haloalkanoic acids, including oxazolidines and thiazolidines, aromatic oxime derivatives, thiazole carboxylic acids and derivatives, substituted phenylpyrimidines, 2-(dichloroacetyl)-2-methyl-1,3-dioxolane and 2-(dichloromethyl)-2-thiazoline.

Abstract: A method of selectively controlling undesirable vegetation in corn by applying an herbicidally effective amount of 2-(2'-nitro-4'-methylsulfonylbenzoyl)-1,3-cyclohexanedione to the locus of such vegetation.

Abstract: This invention embodies compositions comprising herbicidally effective compounds corresponding to the formula ##STR1## in which R.sub.1 and R.sub.2 are independently methyl or ethyl,X is H, methyl, chlorine, bromine, fluorine;Y is chlorine, bromine, fluorine;andn is 0, 1 or 2and a non-phytotoxic antidotally effective amount of an antidote therefor selected from the group of amides of haloalkanoic acids, including oxazolidines and thiazolidines, aromatic oxime derivatives, thiazole carboxylic acids and derivatives, substituted phenylpyrimidines, 2-(dichloroacetyl)-2-methyl-1,3-dioxolane and 2-(dichloromethyl)-2-thiazoline.

Abstract: This invention embodies a two-part herbicidal system comprised of an acylated 1,3-dicarbonyl herbicide compound corresponding to the formula ##STR1## and tautomeric forms thereof wherein R is an aromatic moiety, optionally substituted, and a non-phytotoxic antidotally effective amount of an antidote therefor selected from the group of amides of haloalkanoic acids, including oxazolidines and thiazolidines, aromatic oxime derivatives, thiazole carboxylic acids and derivatives, and 1,8-naphthalic anhydride.
