ABSTRACT:
The present invention relates to novel N-phenyl-N-pyrimidin-2-ylureas having a herbicidal and plant growth-regulating activity, to agrochemical compositions containing those substances as active ingredients, to the use of the novel ureas for controlling weeds or for regulating plant growth, and to processes for the preparation of the novel compounds. The invention also relates to novel intermediates and to processes for the preparation thereof.
The novel compounds correspond to formula I ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 are each, independently of the others, hydrogen; halogen; C.sub.1 -C.sub.4 alkyl; C.sub.1 -C.sub.4 alkoxy; C.sub.1 -C.sub.4 haloalkyl; C.sub.1 -C.sub.4 haloalkoxy; C.sub.1 -C.sub.4 alkyl-S(O).sub.n -; nitro; cyano; C.sub.1 -C.sub.4 alkoxycarbonyl; C.sub.1 -C.sub.4 alkylcarbonyl; di-(C.sub.1 -C.sub.4 alkylamino)-carbonyl; mono-(C.sub.1 -C.sub.4 alkylamino)carbonyl; carbamoyl; C.sub.1 -C.sub.4 haloalkyl-S(O).sub.n -; or -PO[O-(C.sub.1 -C.sub.4)-alkyl].sub.2 ;
