ABSTRACT:
The invention discloses novel herbicidally active and plant growth-regulating benzthiazolylurea derivatives of the formula ##STR1## wherein R.sub.1 is hydrogen, C.sub.1 -C.sub.6 alkyl, C.sub.3 -C.sub.6 alkenyl, C.sub.3 -C.sub.6 -alkylnyl or C.sub.3 -C.sub.6 cycloalkyl; R.sub.2 has the same meaning as R.sub.1 or is C.sub.1 -C.sub.6 alkoxy; R.sub.1 and R.sub.2, together with the nitrogen atom to which they are attached, also form a 5- to 6-membered heterocyclic ring which can be substituted by C.sub.1 -C.sub.3 alkyl; R.sub.3 is hydrogen, C.sub.1 -C.sub.6 alkyl, an alkali metal cation or an alkaline earth metal cation or a C.sub.1 -C.sub.4 alkylammonium radical, the alkyl moieties of which can be substituted by OH, NH.sub.2, CN or C.sub.1 -C.sub.4 alkoxy; R.sub.5 to R.sub.9 are preferably hydrogen or C.sub.1 -C.sub.4 alkyl, but can also have one of the other meanings defined more closely in the specification; X.sub.1 and X.sub.2, each independently of the other, is a C.sub.1 -C.sub.8 alkoxy or C.sub.1 -C.sub.8 alkylthio radical which can be substituted by halogen and/or interrupted by oxygen or sulfur, while X.sub.1 and X.sub.2 together can also be a double bonded oxygen atom or C.sub.2 -C.sub.3 alkylene-dioxide or -disulfide which can be substituted in the alkyl moiety by halogen, C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.6 alkoxy or C.sub.1 -C.sub.4 alkylthio; and Y is an oxygen or a sulfur atom.
