## Abstract

A selective herbicidal composition for controlling grasses and weeds in crops of useful plants comprises a) a herbicidally effective amount of a sulfonylurea of formula I ##STR1## wherein R.sub.1 and R.sub.2 independently of one another are methyl or methoxy; R.sub.3 is hydrogen, halogen, methyl or methoxy; and b) a herbicide-antagonistically effective amount of a quinoline derivative of formula II ##STR2## wherein R is hydrogen or C.sub.1 -C.sub.8 alkyl and X is hydrogen or chlorine.

## Claims

### Claim 1

A composition for the selective control of weeds in crops of useful plants, which, in addition to inert carriers and additives, comprises as active ingredient a mixture comprising
a) a herbicidally effective amount of a sulfonylurea of formula I ##STR9## wherein R.sub.1 and R.sub.2 independently of one another are methyl or methoxy;
R.sub.3 is hydrogen, halogen, methyl or methoxy; and
b) as safener, a herbicide-antagonistically effective amount of a quinoline derivative of formula II ##STR10## wherein R is hydrogen or C.sub.1 -C.sub.8 alkyl and
X is hydrogen or chlorine.

### Claim 2 (depends on 1)

A composition according to claim 1 wherein R.sub.3 is hydrogen.

### Claim 3 (depends on 1)

A composition according to claim 1 wherein R.sub.3 is 4-fluorine.

### Claim 4 (depends on 1)

A composition according to claim 1 wherein R.sub.1 is methoxy.

### Claim 5 (depends on 4)

A composition according to claim 4 wherein X is chlorine and R is C.sub.4 -C.sub.8 alkyl.

### Claim 6 (depends on 5)

A composition according to claim 5 wherein R is 1-methylhexyl.

### Claim 7 (depends on 1)

A composition according to claim 1 wherein R.sub.1 is methyl and R.sub.2 is methoxy.

### Claim 8 (depends on 7)

A composition according to claim 7 wherein X is chlorine and R is C.sub.4 -C.sub.8 alkyl.

### Claim 9 (depends on 8)

A composition according to claim 8 wherein R is 1-methylhexyl.

### Claim 10 (depends on 1)

A composition according to claim 1 comprising a herbicidally effective amount of a sulfonylurea of formula Ia ##STR11## and, as safener, a herbicide-antagonistically effective amount of a quinoline derivative of formula IIa ##STR12##

### Claim 11 (depends on 1)

A method for the selective control of weeds and grasses in crops of useful plants, which comprises treating the crops, the seeds thereof or the cultivated area thereof with an effective amount of a herbicide of formula I according to claim 1 and a herbicide-antagonistically effective amount of a compound of formula II according to claim 1, simultaneously or independently of one another.

### Claim 12 (depends on 11)

A method according to claim 11, which comprises treating crop plants or cultivated areas intended for crop plants with 0.001 to 2 kg/ha of a compound of formula I and an amount of 0.001 to 5 kg/ha of a compound of formula II.

### Claim 13 (depends on 11)

A method according to claim 11 for the selective control of weeds and grasses in cereal crops.

### Claim 14 (depends on 13)

A method according to claim 13, wherein the cereal crops are wheat or barley.
