2-DIMETYLKARBAMOYLIMINO-1,3,4-TIADIAZOLIN-3-ID SALTS, APPROVED TO PREPARE THESE AND HERBICIDES

摘要

The herbicidal composition contains at least one novel 2-(dimethylcarbamoylimino)-1,3,4-thiadiazolin-3-ide salt of the general formula I IMAGE in which R denotes an aliphatic hydrocarbon radical and B(+) denotes a monovalent metal equivalent, as at least one active ingredient. The compounds are distinguished, for example, by a broad soil- and leaf-acting herbicidal activity. They can be used for controlling mono- and dicotyledon weeds. Two preparation processes of the compounds of the formula I are defined in Patent Claim 17.
