Beschreibung
Zusammenfassung:	Novel, herbicidally active substituted sulfonylurea derivatives of the general formula (I), wherein R1 stands for hydrogen, halogen, C1-4 alkoxy, halo-C1-4 alkoxy, C1-3 alkylsulfonyl or a group of the formula COR6; R2 means hydrogen, C1-3 alkyl or phenyl; R3 represents C1-6 alkyl, C3-6 alkenyl, C1-3 alkoxyalkyl group, C2-4 alkyl substituted by one or more halogen(s) or benzyl; R4 and R5 mean independently of each other a C1-4 alkyl, C1-4 alkoxy group, halogen, C1-3 alkylamino or di(C1-3alkyl) amino or C1-3 alkylthio; R6 stands for a C1-4 alkoxy, C3-6 alkenyloxy, C1-3 alkylamino, di(C1-3 alkyl) amino, piperazinyl or morpholinyl group; X means oxygen of sulfur; and E stands for a methine group or nitrogen, their salts as well as herbicide compositions containing these compounds optionally together with an antidote are disclosed. The compositions are highly effective against a number of weeds and selective when used in cultures of cultivated @.
