Abstract
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.
Claims10
A method of selectively treating useful plant crops against weeds and harmful grasses before germination of the seeds, after germination of the seeds or before and after germination of the seeds which comprises applying one or more 4-DL-alkyl ester-.alpha.-alaninyl-6-chloro-s-triazines having the formula (1):
- ##STR9## wherein R.sub.1 is a radical having not more than 10 carbon atoms selected from the group of straight or branched chained alkyl, alkoxy, alkoxyalkyl or alkylol radicals which are unsubstituted, or which are substituted by a cyclopentyl or cyclohexyl group, which is itself, unsubstituted or substituted by up to five 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.
A method of selectively treating useful plant crops against weeds and harmful grasses before germination of the seeds, after germination of the seeds or before and after germination of the seeds which comprises applying a composition comprising an effective amount of one or more 4-DL-alkyl ester-.alpha.-alaninyl-6-chloro-s-triazines having the formula (I):
- ##STR10## wherein R.sub.1 is a radial having not more than 10 carbon atoms selected from the group of straight or branched alkyl, alkoxy, alkoxyalkyl or alkylol radicals which are unsubstituted, or which are 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 hydrogen atoms;
- and R is a radical from the group of alkyl radicals of 1 to about 3 carbon atoms.
