The invention relates to ureas having a herbicidal and plant growth-regulating action of the formula ##STR1## in which R.sup.1 and R.sup.2 each represent, independently of the other, hydrogen, halogen, C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, C.sub.1 -C.sub.4 -alkoxycarbonyl, C.sub.1 -C.sub.4 -alkoxy-(C.sub.1 -C.sub.4)-alkyl, nitro or cyano, and

Pyrimidine-2-phenylamino derivatives

The invention relates to ureas having a herbicidal and plant growth-regulating action of the formula ##STR1## in which R.sup.1 and R.sup.2 each represents, independently of the other, hydrogen, halogen, C.sub.1 -C.sub.6 -alkyl C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, C.sub.1 -C.sub.4 -alkoxycarbonyl, C.sub.1 -C.sub.4 -alkoxy-(C.sub.1 -C.sub.4)-alkyl, nitro or cyano, and

Ureas and their use as herbicides

A method for controlling weeds preferably in the crops of useful plants by using a 1-methyl-1H-imidazole-5-carboxylic acid derivative; herbicidal compositions containing the same; 1-methyl-1H-imidazole-5-carboxylic acid derivatives.

Herbicidal imidazole-5-carboxylic acid derivatives

N-Pyrimidin-4-yl-N'-sulfonylureas of the formula I and the basic addition salts thereof have herbicidal properties and properties for regulating, especially inhibiting, plant growth: ##STR1## the symbols in this formula having the following meanings: Q is halogen, lower alkyl, lower haloalkyl, lower alkoxy, lower haloalkoxy, nitro, amino, lower alkyl or dialkylamino, lower alkoxycarbonyl, formyl, lower alkoxyalkyl, lower alkoxyalkoxy, lower alkylthio, lower alkylsulfinyl or alkylsulfonyl, C.sub.1 -C.sub.4 -alkenyl or C.sub.1 -C.sub.4 -alkynyl,
