Abstract

A herbicidal mixture, comprising a) a herbicidally effective amount of an imidazolinone herbicide selected from the group consisting of imazamox, imazapic, imazapyr; b) an adjuvant comprising at least one of the following components: a partial phosphoric ester or a partial sulfuric ester of a monohydroxy-functional polyalkyl ether and optionally c) a further additive.

Claims

1. A herbicidal mixture, comprising

a) a herbicidally effective amount of at least one imidazolinone herbicide selected from the group consisting of imazamox, imazapic, and imazapyr;

b) at least one adjuvant which is a partial phosphoric ester or a partial sulfuric ester of a monohydroxy-functional polyalkyl ether

and optionally

c) a further additive.

2. A herbicidal mixture as claimed in claim 1, wherein the imidazolinone herbicide is imazapyr, imazamox or a mixture thereof.

3. A herbicidal mixture as claimed in claim 1 wherein the imidazolinone herbicide is imazapyr.

4. A herbicidal mixture as claimed in claim 1, wherein the adjuvant b) is a partial phosphoric ester of a monohydroxy-functional polyalkyl ether and the component c) is an alkyl polyoxyalkylene polyether.

5. A herbicidal mixture as claimed in claim 1, wherein the adjuvant b) is KLEARFAC®

AA 270.

6. A herbicidal mixture as claimed in claim 1, wherein the adjuvant b) is KLEARFAC®

AA 270 and the component c) is present and is an alkyl polyoxyalkylene polyether.

7. A herbicidal finished formulation comprising the herbicidal mixture as defined in claim 1 and further additives.

8. A herbicidal composition comprising the herbicidal mixture as defined in claim 1 and water.

9. A process for preparing a herbicidal mixture as defined in claim 1, which comprises mixing the components a) and b) of the herbicidal mixture.

10. A process for preparing a herbicidal composition as defined in claim 7, which comprises mixing the components a) and b) of the herbicidal mixture and further additives.

11. A process for preparing a herbicidal composition as defined in claim 8, which comprises mixing water with the components a) and b) of the herbicidal mixture with or without further additives.

14. A method for controlling undesirable vegetation in forestry, which comprises allowing a herbicidally effective amount of the components a) and b) of the herbicidal mixture as claimed in claim 1 to act separately or jointly on the vegetation or the vegetation habitat.

17. The herbicidal mixture of claim 1, wherein the components a) and b) are present in a weight ratio of 1 to 99:

99 to 1.

18. The herbicidal composition of claim 17, wherein the weight ratio is 20 to 80:

80 to 20.

19. The herbicidal composition of claim 18, wherein the weight ratio is 45 to 55:

55 to 45.

12. A method for controlling undesirable vegetation, which comprises allowing a herbicidally effective amount of a herbicidal mixture comprising at least one imidazolinone herbicide selected from the group consisting of imazamox, imazapic, and imazapvr;

and

at least one adjuvant comprising a partial phosphoric ester or a partial sulfuric ester of a monohydroxy-functional polyalkyl ether to act separately or jointly on the vegetation or habitat thereof.

13. A method for controlling undesirable vegetation as claimed in claim 12, wherein the undesired vegetation is in the presence of trees.

15. The method of claim 12, wherein the herbicidal mixture is in the form of a finished formulation.

16. The method of claim 12, wherein the herbicidal mixture contains water.

20. The method of claim 12, wherein the imidazolinone herbicide is imazapyr.
