A selective herbicidal composition for controlling grasses and weeds in crops of cultivated plants, comprising 

Herbicidal composition

A selectively herbicidal composition which comprises, besides customary inert formulation auxiliaries, as active ingredient a mixture of: a) a herbicidally active amount of a herbicide selected from the group consisting of the compounds of formula (Ia), and/or (Ib), in which R is hydrogen or fluorine and/or (Ic) or of a salt of the compounds of formulae (Ia) and/or (Ib) and/or (Ic), and b) a herbicidally antagonistically active amount of a compound of formula (IIa), of a compound of formula (IIb), of a compound of formula (IIb), of a compound of formula (IIc), of a compound of formula (IIe), of a compound of formula (IIf), or of a compound of formula (IIg), in which the substituents have the meanings given in claim

Herbicide agent

The present invention relates to novel herbicidally active 3-hydroxy-4-aryl-5-oxopyrazoline derivatives, to processes for their preparation, to compositions which comprise these compounds and may additionally comprise safeners, and to the use of these compounds as herbicides for controlling weeds and grasses, in particular in crops of useful plants.

Herbicidally active 3-hydroxy-4-aryl-5-oxopyrazoline derivatives

A selective herbicidal composition for controlling grasses and weeds in crops of cultivated plants, comprising a) a herbicidally effective amount of a herbicide of formula I ##STR1## and b) to antagonise the herbicide, an antidotally effective amount of a safener selected from the group of the compounds of formula 1.01 (CGA 185,072), 2.01, 2.05, 3.03, 4.001, 5.006 (benoxacor), and 6.02 (fluxofenim). ##STR2##

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

Mixtures of a herbicidally effective amount of a haloacetamide of formula I ##STR1## and, to antagonize the herbicide, an antidotally effective amount of a compound of formula II

Safened dimethenamid herbicidal compositions

A selective herbicidal composition for the control of grasses and weeds in crops of useful plants comprises a) a herbicidally effective amount of a pyrimidine of formula I ##STR1## wherein the substituents are defined in claim 1 and b) as safener a herbicide-antagonistically effective amount of an N-acylsulfamoylphenylurea of formula IIb ##STR2## wherein the substituents are defined in claim 1.
