Abstract: The invention relates to a plant protecting composition which contains 1 to 80% by weight substituted alkoxycarbonyl dithiocarbamates or thiolcarbamates of formula (I) ##STR1## wherein R.sup.1 and R.sup.2 are the same or different and stand for hydrogen, straight or branched chain, saturated or unsaturated alkyl, alkoxyalkyl, alkylaminoalkyl, dialkylaminoalkyl having 1 to 10 carbon atoms, cycloalkyl, phenyl or halogenphenyl,R.sup.3 stands for straight or branched chain, saturated or unsaturated alkyl, cycloalkyl, phenyl or halogenphenyl, andX stands for oxygen or sulfur,as well as 10 to 90% by weight solid and/or liquid diluent(s) and 1 to 30% by weight additive(s).The novel compounds of formua (I) may be obtained in such way that a salt of disubstituted dithiocarbamic acid or thiolcarbamic acid of formula (II) ##STR2## wherein R.sup.1, R.sup.

Abstract: The invention relates to a herbicide composition as well as to the preparation of carboxylic-acid-amido-thiol-carbamate derivatives forming the active agent of the composition. The carboxylic acid-amido-thiolcarbamate derivatives are illustrated by general formula (I) ##STR1## wherein R.sub.1 and R.sub.2 can be identical or different and can stand for hydrogen, a C.sub.1-10 straight or branched alkyl group, a C.sub.2-10 straight or branched alkenyl group, a C.sub.5-6 cycloalkyl or phenyl group, a phenyl radical substituted by a C.sub.1-3 alkyl group, a C.sub.1-3 dialkyl group or halogen, but R.sub.1 and R.sub.2 can form together a hexamethylene group, too;R.sub.2 can stand for a C.sub.1-5 straight or branched alkyl radical;R.sub.4 can represent a C.sub.1-10 straight or branched alkyl group, a C.sub.2-10 straight or branched alkenyl group, furthermore a phenyl or benzyl radical.
