The optically active mixture of isomers of aRS,1'S(-)-N-(1'-methyl-2'-methoxyethyl)-N-chloroacetyl-2-ethyl-6-methylan iline has improved action against problem weeds over the racemic mixture of isomers known as 'Metolachlor'.

Optically active

The optically active isomer of S(-)-N-(1'methyl-2'-methoxyethyl)-N-chloroacetyl-2,6-dimethylaniline has improved action against problem weeds over the racemic mixture of isomers.

N-(1'-methyl-2'-methoxyethyl)-N-chloroacetyl-2,6-dimethylaniline as

2-Chloro-N-(2'-methoxypropyl)- and 2-chloro-N-(2'ethoxypropyl)-2',6'-dimethyl-acetanilide are very effective agents for combating weeds and for regulating plant growth with improved stability in the soil.

2-Chloro-N-(2'-methoxypropyl)- and

2,6-diethyl-N-(1'-methoxyprop-2'-yl)[N]-chloroacetanilide is disclosed as plant growth regulating and herbicidal agent with improved stability in the soil.

Herbicidal and plant growth inhibiting agent

2-Chloro-2',6'-dimethyl-N-(2-methoxyethyl)-acetanilide is disclosed as plant growth regulating agent with long lasting activity.

Plant growth regulating agent

2-Ethyl-6-methyl-N-(1'-ethoxyprop-2'-yl)-N-chloroacetanilide is disclosed as plant growth regulating and herbicidal agent with improved stability in the soil.

2,6-DIETHYL-N-(2'-propoxyethyl)-chloroacetanilide is an outstanding selective herbicide for combating weeds in rice cultures.

2,6-Diethyl-n-(2'-N-propoxyethyl)-chloroacetanilide for selectively

2-CHLORO-2',6'-DIMETHYL-N-(1-ethoxyprop-2-yl)-acetanilide is disclosed as plant growth regulating and herbicidal agent with improved stability in the soil.

Acetanilide plant growth regulating agent

N-(Cycloalkylalkoxymethyl)-halogenoacetanilides are very suitable for selectively combating of weeds in cultivated plants such, for example, as maize, soya, cotton, sorghum sugar beets.

Halogeno-acetanilides as herbicides

N-(2'-alkoxy-ethyl)-N-chloroacetyl-2,3,6-trimethyl-anilines wherein the alkoxy residue is methoxy, ethoxy or isopropoxy are effective weedkillers in plant crops, such as soya and cotton. They may also be used for retarding plant growth.

Plant growth regulation with

2-ETHYL-6-METHYL-N-(1'-methoxyprop-2'-yl)-N-chloroacetanilide is disclosed as plant growth regulating and herbicidal agent with improved stability in the soil.

2-Chloro-2',6'-dimethyl-N-(1-methoxyprop-2-yl)-acetanilide is disclosed as plant growth regulating and herbicidal agent with improved stability in the soil.

Compounds of the Formula I ##STR1## wherein R represents alkyl having from 1 to 4 carbon atoms and one of the symbols R.sub.1 and R.sub.2 is methyl and the other is hydrogen possess favorable herbicidal properties for practical purposes when used in crops for controlling their infestation by undesired plant growth.

Substituted 2-azabicycloalkanes as selective herbicides

2-chloro-2',6'-dimethyl-N-(1-methoxyprop-2-yl)-acetanilide is disclosed as plant growth regulating and herbicidal agent with improved stability in the soil.
