ABSTRACT:
N-Pyridinesulfonyl-N'-pyrimidinyl- and -triazinylureas of the formula I ##STR1## in which R.sub.1 and R.sub.2 independently of one another are hydrogen, C.sub.1 -C.sub.8 alkyl or C.sub.3 -C.sub.8 cycloalkyl; C.sub.2 -C.sub.8 alkyl or C.sub.3 -C.sub.8 cycloalkyl substituted by halogen; C.sub.1 -C.sub.8 alkyl or C.sub.3 -C.sub.8 cycloalkyl substituted by --NR.sub.5 R.sub.6, C.sub.1 -C.sub.4 alkoxy or C.sub.1 -C.sub.4 alkyl-S(O).sub.n --; C.sub.1 -C.sub.4 alkyl or C.sub.3 -C.sub.6 cycloalkyl substituted by C.sub.2 -C.sub.4 alkenyl, C.sub.5 -C.sub.6 cycloalkenyl, C.sub.2 -C.sub.6 alkynyl or C.sub.4 -C.sub.8 alkadienyl; or C.sub.2 -C.sub.4 alkenyl, C.sub.5 -C.sub.6 cycloalkenyl and C.sub.4 -C.sub.8 alkadienyl substituted by halogen; or R.sub.1 and R.sub.2 together are a 4-5-membered C.sub.4 -C.sub.10 alkylene chain which can be interrupted by oxygen, sulfur or N--R.sub.7 ; R.sub.3 is hydrogen, halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy or C.sub.1 - C.sub.4 alkylthio; C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy or C.sub.1 -C.sub.4 alkylthio substituted by halogen; R.sub.4, R.sub.5, R.sub.6 and R.sub.7 independently of one another are hydrogen or C.sub.1 -C.sub.4 alkyl; n is 0, 1 or 2; X is C.sub.1 -C.sub.3 alkyl, or C.sub.1 -C.sub.3 alkyl which is substituted by 1 to 3 halogens; C.sub.1 -C.sub.3 alkoxy, or C.sub.1 -C.sub.3 alkoxy which is substituted by 1 to 3 halogens; Y is halogen, C.sub.1 -C.sub.3 alkyl or C.sub.1 -C.sub.3 alkyl which is substituted by 1 to 3 halogens; C.sub.1 -C.sub.3 alkoxy, or C.sub.1 -C.sub.3 alkoxy which is substituted by 1 to 3 halogens; cyclopropyl, methylamino or dimethylamino; and E is nitrogen or the methine group, and the salts of these compounds with amines, alkali metal bases or alkaline earth metal bases or with quaternary ammonium bases have good selective herbicidal and growth-regulating properties when used pre- and post-emergence.
