Abstract

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

First claim

The invention claimed is:

1. A herbicidal composition comprising, as sole herbicidally active constituents in the composition,
A) aclonifen (component A),
B) pyroxasulfone (component B) and
C) picolinafen (component C),
wherein combination of said A, B, and C provides a synergistically enhanced activity which allows an application rate to be reduced compared to an individual application rate of the active constituents, A, B or C.

2. The herbicidal composition as claimed in claim 1 , wherein the herbicide components A, B, and C, with respect to one another, are present in a weight ratio of:
(1-100):(1-100):(0.1-100).

3. The herbicidal composition as claimed in claim 1 , comprising the respective herbicide components in amounts for an application rate of:
component A: 10-5000 g of AS/ha of aclonifen;
component B: 10-300 g of AS/ha of pyroxasulfone;
component C: 1-500 g of AS/ha.

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

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

6. The herbicidal composition as claimed in claim 1 , wherein the herbicide components A, B, and C, with respect to one another, are present in a weight ratio of (1-25):(1-25):(0.5-50).

7. The herbicidal composition as claimed in claim 1 , wherein the herbicide components A, B, and C, with respect to one another, are present in a weight ratio of (1-10):(1-10):(1-10).

8. The herbicidal composition as claimed in claim 1 , comprising the respective herbicide components in amounts for an application rate of:
component A: 80-3000 g of AS/ha of aclonifen;
component B: 25-100 g of AS/ha of pyroxasulfone;
component C: 10-300 g of AS/ha, of picolinafen.

9. The herbicidal composition as claimed in claim 1 , comprising the respective herbicide components in amounts for an application rate of:
component A: 80-1000 g of AS/ha of aclonifen;
component B: 25-75 g of AS/ha of pyroxasulfone;
component C: 30-200 g of AS/ha of picolinafen.

10. A method for controlling unwanted vegetation which comprises applying the components A, B and C of the herbicidal compositions, defined in claim 1 , jointly or separately to one or more plants, plant parts, plant seeds and/or an area on which the plants grow.

11. The method as claimed in claim 10 , wherein harmful plants in plant crops are controlled.

12. The method as claimed in claim 11 in which the plant crops are genetically modified or have been obtained by mutation selection.
