A herbicidal compound, and a method of use therefor, for the selective treatment of useful plant cultures, having a broad spectrum of activity against weeds and noxious grasses in pre-emergence and/or post-emergence periods having the formula: ##STR1## wherein R.sub.1 is a straight-chain or branched-chain alkyl, alkoxy, alkoxyalkyl, or alkylol radical having less than a total of 15 oxygen and carbon atoms combined, or a hydrogen atom; (R) is a lower alkyl group; A is --CH.sub.2 -- or --CH.sub.2 CH.sub.2 --; with the proviso that n is 0-6, when A is --CH.sub.2 --, and n is 3-6, when A is --CH.sub.2 CH.sub.2 --; and wherein the substituents (R) on the cycloalkyl ring are identical to or different from each other.

Cycloalkyl amino-s-triazines and their use as selective agents against

4-DL-alkylester-.gamma.-alaninyl-6-chloro-S-triazines having the formula (I): ##STR1## wherein R.sub.1 is a straight or branched chain alkyl, alkoxy, alkoxyalkyl or alkylol radical which is unsubstituted or substituted by a cyclopentyl or cyclohexyl group, which is, itself, unsubstituted or substituted by up to 5 methyl groups; R.sub.2 is a radical from the group of alkyl radicals of 1 to about 3 carbon atoms, or a hydrogen atom; and R is a radical from the group of alkyl radicals of 1 to about 3 carbon atoms.

4-DL-Alkylester-.alpha.-alaninyl-6-chloro-S-triazines and the use

Herbicidal-substituted .alpha.-(trimethylcycloalkenyl)-N-alkylacetamides of the formula ##STR1## wherein R is a linear or branched alkyl or alkoxyalkyl radical with 1-6 carbon atoms or an allyl radical, optionally substituted with C.sub.1 -C.sub.4 alkylene groups, and X is a substituent from the group consisting of hydrogen, methyl, chlorine and bromine, in any combination, the free valences signify hydrogen and two of the methyl groups on the ring are attached to the same carbon atom, are useful pre- and post-emergent herbicides for weed control in crops.
