Novel compounds and their herbicidal use having the formula ##STR1## wherein A is selected from the group ##STR2##

Herbicidal meta-bifunctional benzenes

Herbicidal ureido containing carbanilates

N,N-disubstituted-N'-arylamidino dialkyldithiocarbamate hydrochlorides are prepared by reaction of trisubstituted thioureas with disubstituted thiocarbamoyl chlorides. N,N-disubstituted-N'-arylamidino dialkyldithiocarbamate hydrochlorides are particularly useful as pre-emergent and contact herbicides.

Dithiocarbamate hydrochloride salts and their manufacture

Meta-bifunctional of the general formula ##EQU1## wherein A is selected from the groups ##EQU2## These compounds possess herbicidal activity.
