## Abstract

The present invention relates to the use of a herbicidal composition comprising as component A) 4-(2,4-dichlorophenoxy)butanoic acid or salts or esters thereof and as component B) 3,6-dichloro-2-methoxybenzoic acid or salts or esters thereof for controlling unwanted vegetation in crop plants. The present invention also relates to a method for controlling unwanted vegetation in crop plants, which comprises allowing a composition comprising said components A) and B) to act on plants, their seeds and/or their habitat.

## Claims

### Claim 1

A method for controlling unwanted vegetation in crop plants, which comprises treating plants, their seeds and/or their habitat with a herbicidal composition comprising as component
A) 4-(2,4-dichlorophenoxy)butanoic acid of formula (I) or salts or esters thereof
and as component
B) 3,6-dichloro-2-methoxybenzoic acid of formula (II) or salts or esters thereof,
wherein the weight ratio of components A) to B) based on acid equivalents is from 1:12 to 1:50.

### Claim 2 (depends on 1)

The method of claim 1, wherein the weight ratio of components A) to B) based on acid equivalents is from 1:12 to 1:24.

### Claim 3 (depends on 1)

The method of claim 1, wherein the composition comprises components A) and B) in a total amount of from 300 to 1300 g of active ingredients per hectar based on acid equivalents.

### Claim 4 (depends on 1)

The method of claim 1, wherein the component B) is dicamba-N,N-bis-(3-aminopropyl)methylamine salt or dicamba-diethylenetriamine salt.

### Claim 5 (depends on 1)

The method of claim 1, wherein the component A) and the component B) are the respective N,N-bis-(3-aminopropyl)methylamine salt or diethylenetriamine salt.

### Claim 6 (depends on 1)

The method of claim 1, wherein the crop plant is soybean.

### Claim 7 (depends on 1)

The method of claim 1, wherein the unwanted vegetation to be controlled is selected from the family of Amaranthaceae.

### Claim 8 (depends on 1)

The method of claim 1, wherein the unwanted vegetation to be controlled is selected from the class of Amaranthus.

### Claim 9 (depends on 1)

The method of claim 1, wherein the crop plants are tolerant or resistant to component A) and/or component B).

### Claim 10

A method for controlling unwanted vegetation in crop plants, which comprises applying simultaneously, separately, or in succession:
component
A) 4-(2,4-dichlorophenoxy)butanoic acid of formula (I) or salts or esters thereof
and component
B) 3,6-dichloro-2-methoxybenzoic acid formula (II) or salts or esters thereof,
at a weight ratio of components A) to B) based on acid equivalents of from 1:12 to 1:50; on plants, their seeds, or their habitat.

### Claim 11 (depends on 10)

A method as claimed in claim 10, wherein the compounds are applied after emergence of the crop plant.

### Claim 12 (depends on 10)

The method of claim 10, wherein the weight ratio of components A) to B) based on acid equivalents is from 1:12 to 1:24.

### Claim 13 (depends on 10)

The method of claim 10, a total amount of from 300 to 1300 g of active ingredients per hectar based on acid equivalents.

### Claim 14 (depends on 10)

The method of claim 10, wherein the component B) is dicamba-N,N-bis-(3-aminopropyl)methylamine salt or dicamba-diethylenetriamine salt.

### Claim 15 (depends on 10)

The method of claim 10, wherein the component A) and the component B) are the respective N,N-bis-(3-aminopropyl)methylamine salt or diethylenetriamine salt.

### Claim 16 (depends on 10)

The method of claim 10, wherein the crop plant is soybean.

### Claim 17 (depends on 10)

The method of claim 10, wherein the unwanted vegetation to be controlled is selected from the family of Amaranthaceae.

### Claim 18 (depends on 10)

The method of claim 10, wherein the unwanted vegetation to be controlled is selected from the class of Amaranthus.

### Claim 19 (depends on 10)

The method of claim 10, wherein the crop plants are tolerant or resistant to component A) and/or component B).
