Abstract

Herbicidal compositions having an effective amount of aclonifen and the other herbicides pendimethalin 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) pendimethalin (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)
is (1-10):(1-100):(1-10),
and the components are present in amounts to provide synergistic results.

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 components selected from the group consisting of agrochemical active compounds comprising 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. The herbicidal composition as claimed in claim 1 , wherein the weight ratio of (range component A):(range component B):(range component C) is (1-10):(1-10):(1-10).

6. 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 pendimethalin, and component C is diflufenican
wherein the herbicide components, with respect to one another, are applied in the weight ratio stated below:(range component A):(range component B):(range component C)
is (1-10):(1-100):(1-10)
and the components are applied in amounts to provide synergistic results.

7. The method as claimed in claim 6 for the selective control of harmful plants in plant crops.

8. The method as claimed in claim 7 in which the plant crops are genetically modified or have been obtained by mutation selection.

9. The method as defined in claim 6 comprising controlling one or more harmful plants.

10. The method as defined in claim 6 comprising controlling one or more herbicide-resistant harmful plants.

11. The method as claimed in claim 6 , wherein component B is applied from 500 to 3000 g of AS/ha of pendimethalin.

12. The method as claimed in claim 6 , wherein component B is applied from 500 to 2500 g of AS/ha of pendimethalin.

13. The method as claimed in claim 6 , wherein component B is applied from 500 to 1200 g of AS/ha of pendimethalin; and component C is applied from 30 to 200 g of AS/ha of diflufenican.

14. The method as claimed in claim 6 , wherein component B is applied from 300 to 2500 g of AS/ha of pendimethalin.
