Abstract

Herbicide combinations comprising an effective amount of components (A) and (B), where
component (A) is/are one or more herbicides of the formula (I) or salts thereof,

in which
R 1 is H or a group of the formula CZ 1 Z 2 Z 3 , where Z 1 , Z 2 and Z 3 are as defined in claim 1, R 2 and R 3 are each H, alkyl, haloalkyl, alkenyl, haloalkenyl, alkynyl, haloalkynyl having in each case up to 4 carbon atoms or acyl, R 4 is H, (C 1 -C 6 )-alkyl or (C 1 -C 6 )-alkoxy; R 5 , R 6 , R 7 and R 8 are each H, (C 1 -C 4 )-alkyl, (C 1 -C 3 )-haloalkyl, halogen, (C 1 -C 3 )-alkoxy, (C 1 -C 3 )-haloalkoxy or cyano; A is CH 2 or O or a direct bond, and the component (B) is one or more herbicides from the group of compounds consisting of (B1) thiencarbazone, tembotrione, SYN-523, pyroxsulam, penoxsulam, SYN-449, (B2) pyrasulfotole, trifloxysulfuron, saflufenacil, aminopyralid, ethofumesate, aminocyclopyrachlor and (B3) pyroxasulfone (KIH-485)

are suitable for controlling harmful plants or for regulating the growth of plants.

First claim

The invention claimed is:

1. A herbicide combination comprising:
an effective amount of components (A) and (B); wherein component A includes one or more herbicidally active compounds (A) selected from the group consisting of:

wherein component (B) is one or more herbicidally active compounds (B) selected from the group consisting of:
(B1.2.1) tembotrione;
(B1.3) ethyl [[3-[2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2H)-pyrimidinyl]-4-fluorophenoxyl-2-pyridinyl]oxy]acetate (SYN-523);
(B1.4.1) pyroxsulam;
(B1.6.1) 4-hydroxy-3-[[2-[(2-methoxyethoxy)methyl]-6-trifluoromethyl-3-pyridinyl]carbonyl]bicyclo[3.2.1]oct-3-en-2-one (SYN-449);
(B2.2.2) trifloxysulfuron sodium salt;
(B2.3.1) saflufenacil;
(B2.4.1) aminopyralid;
(B2.5) ethofumesate; and
(B3.1) pyroxasulfone (KIH-485).

2. The herbicide combination as claimed in claim 1 ;
wherein active compound components (A) and (B) are present in a weight ratio of from 1:100000 to 2000:1.

3. The herbicide combination as claimed in claim 1 ;
wherein active compound components (A) and (B) are present in a weight ratio of from 1:40000 to 750:1.

4. The herbicide combination as claimed in claim 1 ;
which comprises one or more further components from the group comprising crop protection agents.

5. A herbicidal composition which comprises:
the herbicide combination as claimed in claim 1 ; and one or more additives customary in crop protection.

6. A method for controlling harmful plants which comprises:
applying a synergistically effective amount of the active compound components of the herbicide combination as defined in claim 1 together or separately, by the pre-emergence method, by the post-emergence method, or by the pre-emergence and the post-emergence method, onto the plants, parts of plants, plant seeds, or the area where the plants grow.

7. The method as claimed in claim 6 ;
wherein the herbicide component (A) is applied in an application amount of from 0.01 to 2000 g of active substance per hectare and the herbicide component (B) is applied in an application amount of from 0.01 to 1000 g of active substance per hectare.

8. The method as claimed in claim 6 for the control of harmful plants on non-crop land or in plantation crops.

9. The method as claimed in claim 6 ;
wherein the active compounds of the herbicide combination are applied in the form of a herbicidal composition which comprises one or more additives customary in crop protection, if appropriate after dilution with water.

10. A herbicide combination comprising:
a synergistically effective amount of components (A) and (B); wherein component A comprises:

wherein component (B) comprises one or more compounds (B) selected from the group consisting of:
(B2.6) aminocyclopyrachlor and its salts and esters.

11. The herbicide combination as claimed in claim 10;
wherein components (A) and (B) are present in a weight ratio of from 1:100000 to 2000:1.

12. The herbicide combination as claimed in claim 10;
wherein components (A) and (B) are present in a weight ratio of from 1:40000 to 750:1.

13. The herbicide combination as claimed in claim 10;
wherein components (A) and (B) are present in a weight ratio of from 1:75000 to 200:1.

14. The herbicide combination as claimed in claim 10;
components (A) and (B) are present in a weight ratio of from 1:25000 to 75:1.

15. The herbicide combination as claimed in claim 10;
which comprises one or more crop protection agents.

16. A herbicidal composition which comprises:
the herbicide combination as claimed in claim 10; and one or more additives customary in crop protection.

17. A method of controlling harmful plants, said method comprising applying an herbicide combination according to claim 10 together or separately, by the pre-emergence method, by the post-emergence method, or by the pre-emergence and the post-emergence method, onto the plants, parts of plants, plant seeds, or the area where the plants grow on a path, rail track, or industrial terrain.

18. The method as claimed in claim 17;
wherein the herbicide component (A) is applied in an application amount of from 0.01 to 2000 g of active substance per hectare and the herbicide component (B) is applied in an application amount of from 0.01 to 1000 g of active substance per hectare.

19. The method as claimed in claim 17;
wherein component (B) is applied in an application amount of from 2 to 350 g of active substance per hectare.

20. The method as claimed in claim 17;
