A selective herbicidal composition for controlling grasses and weeds in crops of cultivated plants, comprising, in addition to inert carriers and adjuvants, as active component a mixture of a) a herbicidally effective mount of a N-phenylsulfonyl-N'-triazinylurea of formula I ##STR1## wherein the substituents are as defined in claim 1, and b) to antagonise the herbicide, an antidotally effective mount of a quinoline derivative of formula IIa ##STR2## wherein R.sub.10 is hydrogen, C.sub.1 -C.sub.8 alkyl or C.sub.1 -C.sub.8 alkyl which is substituted by C.sub.1 -C.sub.6 alkoxy or C.sub.3 -C.sub.6 alkenyloxy; and X.sub.2 is hydrogen or chloro; or of a 1-phenylazole-3-carboxylic acid derivative of formula IIb ##STR3## wherein E is nitrogen or methine; R.sub.11 is --CCl.sub.3, phenyl or halogen-substituted phenyl; R.sub.12 and R.sub.13 are each independently of the other hydrogen or halogen; and R.sub.14 is C.sub.1 -C.sub.4 alkyl.

Selective safened herbicidal composition

Compounds of the formula XI, wherein R, R.sub.4, R.sub.8 and R.sub.38 are as defined in claim 1, are useful as intermediates in the preparation of compounds of formula I. Mixtures of a herbicidally effective amount of a pyridylsulfonylurea of formula I, ##STR1## wherein R, R.sub.1, R.sub.2 and A are as defined in the specification and of a herbicide-antagonistically effective amount of a sulfamoylphenylurea of formula II, ##STR2## wherein R.sub.7 to R.sub.11 and A.sub.2 are as defined in the specification are very suitable for controlling weeds in crops of useful plants, especially maize and sugar cane.
