Abstract

Herbicidal compositions having an effective amount of aclonifen and the other herbicides pyroxasulfone and diflufenican.
These herbicidal compositions have an improved application profile.

First claim

The invention claimed is:

1. A herbicidal composition comprising, as herbicidally active constituents,
A) aclonifen (component A),
B) pyroxasulfone (component B) and
C) diflufenican (component C)
wherein the herbicide components, with respect to one another, are present in the weight ratio stated below:
(range component A): (range component B): (range component C) of (1-25): (1-10): (1-10)
and wherein the components are present in amounts to give synergistic effects.

2. The herbicidal composition as claimed in claim 1 , additionally comprising one or more formulation auxiliaries and/or additives customary in crop protection.

3. The herbicidal composition as claimed in claim 1 , additionally comprising one or more further agrochemical active compounds selected from the group consisting of insecticides, fungicides and safeners.

4. The herbicidal composition according to claim 1 , wherein components A, B, and C are the sole herbicidally active constituents in the composition.

5. A method for controlling unwanted vegetation which comprises applying components A, B and C of an herbicidal composition jointly or separately to one or more plants, plant parts, plant seeds and/or an area on which plants grow, wherein component A is aclonifen, component B is pyroxasulfone, and component C is diflufenican,
wherein the herbicide components, with respect to one another, are used in the weight ratio stated below:

(range component A): (range component B): (range component C) (1-25): (1-10): (1-10)
and wherein the components are used in amounts to give synergistic effects.

6. A method as defined in claim 5 comprising controlling one or more harmful plants.

7. A method as defined in claim 5 comprising controlling one or more herbicide-resistant harmful plants.

8. The method as claimed in claim 5 for the selective control of harmful plants in plant crops.

9. The method as claimed in claim 8 in which the plant crops are genetically modified or have been obtained by mutation selection.

10. The method as claimed in claim 5 , wherein component B is applied from 10 to 100 g of AS/ha of pyroxsulfone.

11. A method for controlling unwanted vegetation which comprises applying components A, B, and C of an herbicidal composition jointly or separately to one or more plants, plant parts, plant seeds, and/or an area on which plants grow, wherein component A is aclonifen, component B is pyroxasulfone, and component C is diflufenican, and wherein:
component A is applied from 80 to 1000 g of AS/ha of aclonifen;
component B is applied from 10 to 75 g of AS/ha of pyroxasulfone;
component C is applied from 30 to 200 g of AS/ha of diflufenican; and

wherein the components are used in amounts to give synergistic results.
